Abstract

PROBLEM TO BE SOLVED: To simultaneously solve a contrary countermeasure since it is necessary to make bulkhead using a strong concrete block for protecting an urban environment for enduring against increasing local heavy rain accompanied by global warming on one hand, and a river environment is deteriorated by a change in an ecological system when a food chain in an underwater organism is not continued, since the deterioration in a water quality environment proceeds, when a varied flow where it is easy for underwater organisms to live, an evacuation place in flooding time and also a varied bulkhead for compensating for dissolved oxygen are eliminated on the other hand.SOLUTION: When installing a different diameter hole fish bed block having a surface having a large number of different size holes integrally formed by deadly burying a waste vinyl chloride pipe, for protecting a nest of an underwater organism and a hole of a bed from the frictional deterioration from the inside, it is continuously laid such that a surface where a fish bed hole does not exist touches at an acute angle, at almost 60 degrees in a straight line and at the acute angle in a curve by adjusting in accordance with a radius with respect to a water flowing direction so that a water flow does not directly enter the inside of a fish bed hole, and is laid in a sawtooth shape of making a deposit hardly enter the fish bed hole or making oxygen easily melt into by making a reversal flow on the fish bed hole periphery.SELECTED DRAWING: Figure 1

Description

The present invention reinforces the revetment of rivers and the like by stacking square blocks of concrete blocks making use of weight and unevenness. In the river straight line area, the surface without holes for fish beds is arranged at an acute angle of approximately 60 degrees with respect to the main stream, and in the curve, the square pillars are made continuously like a saw blade at an angle according to the radius. One side of the wall creates an arrangement that protrudes in the mainstream direction, it becomes a wall that prevents the mainstream direction from dispersing and the mainstream direction directly hitting the fish bed hole, the back of the wall is a necessary place for improving the breeding environment of aquatic organisms, It is a safe revetment that is gentle to aquatic organisms that have a difference in flow, such as a safe space when underwater organisms appear in the mainstream, and a reverse flow that easily obtains oxygen in the water.
Because of the back of the wall, there is little damage due to sediment accumulation or foreign object collision in the fish hole. A PVC pipe is used when forming the fish bed hole, and it is buried and used for protection to eliminate friction deterioration from the inside of the concrete hole for the fish bed, thereby enhancing the overall durability. In addition, by using waste PVC pipes to fill, the greenhouse gas generated in the material recycling process of waste PVC pipes can be reduced by all the waste PVC pipes that have been buried, and the combined environmental improvement and strengthening of the revetment can be achieved. This is related to the saw blade type laying revetment method for the target different diameter hole fish bed block.

In recent years, local heavy rains that seem to be affected by global warming have occurred frequently. Moreover, there are many cases where the assumption is exceeded and reinforcement of the revetment is urgently needed. At the same time, retaining walls combining fish nest blocks are being used to increase the breeding place for aquatic organisms. For example (see Patent Document 1), the passage communicated through the opening on the side surface of the revetment fish nest block is arranged obliquely with respect to the river extension direction, and therefore obliquely with respect to the river mainstream. Therefore, the water flow that flows into the block from the opening on the front side of each block is forced to turn diagonally with respect to the main flow direction of the river when passing through the block row, so it is decelerated. Some fish have entered the block so that they can easily move upstream without receiving excessive water resistance.

  Also (see Patent Document 2), there are some that lay eggs in rough concrete such as unglazed clay pipes, bamboo charcoal, and shells in concrete to promote egg laying.

  In the above-mentioned Patent Document 1, there is an unsolved problem that a complicated flow occurs in the block at the time of water increase and a space for weakened underwater creatures to hide can not be obtained. According to Patent Document 2, the fish nest block is a straight portion with a 90 ° burrow opening with respect to the water flow, and outside the curve is a sharp burrow opening with respect to the water flow. There are problems of lowering the strength of the revetment, such as damage caused by damage, and the disadvantage that the situation that is dangerous for young and weak fish to enter and exit has not been solved. In addition, because the revetment wall with little change due to the reinforcement of the revetment with concrete cannot reverse flow to increase oxygen in the water, even if aquatic organisms increase on the revetment, dissolved oxygen does not increase and the water quality deteriorates and the food chain does not continue The environmental problem is not solved.

  Therefore, in order to improve the sedimentation in the fish nest and the revetment with low dissolved oxygen, which is a problem of the above-mentioned conventional technology, the present invention makes the hole in the fish bed into the water flow not only in the straight part but also outside the curve. Lay in a saw blade shape with an obtuse angle that does not directly hit. Since the rectangular end of the different-diameter hole fishbed block hits the water flow, a reverse flow can be generated, and the surface area of the water surface can be increased, so that oxygen can be easily taken into the water. Since the water flow does not directly hit the fish bed hole, sediment accumulation can be prevented and the possibility of drifting objects coming into the shore can be reduced. Furthermore, the present invention contributes to the reduction of greenhouse gas, which is said to be the source of abnormal weather that contributes to strengthening the revetment, so that PVC pipes have the role of protecting concrete holes from the inside when making fish beds. By using waste PVC, it is possible to contribute to a comprehensive reduction of greenhouse gases because the greenhouse gases that were originally emitted during the material recycling process are no longer emitted due to the use change recycling.

  When making a square pillar concrete block with through holes for fish nests and bedding, to protect against friction degradation from the inside of the holes, the PVC pipes are buried and integrally formed to protect the holes. When manufacturing a different-diameter hole fish floor block with a large number of surfaces, the wall dimensions of the frame required to maintain the strength of the square pillar concrete block are measured from the fish floor hole to an iron or PVC pipe or Secured to be used as a spacer by assembling in a cross-beam shape with square bars and reinforcing bars, etc., and ensuring a dimension that allows concrete to be filled between a PVC pipe for forming a fish bed hole and protecting it from the inside and an adjacent PVC pipe of the same purpose In order to maintain the strength, a PVC pipe with a dimension equal to or less than the length obtained by subtracting the dimension of the concrete frame wall from the total length of the fish floor hole is buried as a spacer.

  Reinforce with piles with different diameter holes, integrated with unevenness such as anti-slip, or with holes for reinforcing piles when there is a possibility of movement due to the formation or water flow To do.

  In order to prevent the mainstream from entering the fishbed hole directly when installing a different-diameter fishbed block, the surface without the fishbed hole is an acute angle with respect to the mainstream direction, approximately 60 degrees for straight lines, and the radius for curves. It is laid like a saw blade continuously so that it hits an acute angle, and deposits are difficult to enter the fish bed hole, and a reverse flow is created around the fish bed hole so that oxygen is easily dissolved.

  The use of waste PVC pipes as PVC pipes used to form and protect different-diameter fish floor holes reduces greenhouse gases generated during the material recycling process of waste PVC pipes.

  In order to use waste PVC pipes for purposes other than fluid transportation, construct a system that can be washed, cut to the required dimensions, and used for recycling applications.

The revetment is reinforced with concrete in an orderly manner, creating a reversal flow throughout the revetment and constantly replenishing underwater oxygen, creating an environment where aquatic life is liable to live.
Each different-diameter fish bed block has a saw hole that allows underwater organisms to escape even during sudden water increases or abnormal heat, and can move to a different-diameter fish bed hole as it grows. become.
Since the surface with a different diameter hole is the backside that is not directly affected by the main stream, there is little risk of foreign objects and dust being caught, there is no risk of accumulation, and there is less risk of damage to the revetment.
When the concrete block square pillar 1m x 1m x 1m = 1m ³ and the revetment reinforcement utilizing the strength and weight is set to at least 0.08t or more, the pipe block of different diameter holes is used. By using one, the greenhouse gas can be reduced from the material recycling treatment process for waste PVC pipes of 0.08t or more.

FIG. 2 is a completed perspective view of a different-diameter hole fishbed block according to the present invention. FIG.

Hereinafter, the creation and installation of the different diameter hole fishbed block in the present invention will be described with reference to FIGS. Open the upper part and one side of the temporary frame and form a well girder using 4 clamps with a spacer for securing 1 wall thickness and set it in the temporary frame. 2 Set up the concrete-blocked PVC pipe in the concrete hole, set up the spacer short PVC pipe between the 3 PVC pipes, and secure the cover. Install. This final state is an elevational sectional view 3 and a plan sectional view is shown in FIG.
Fix the temporary frame on the side and cover the concrete hole in the concrete hole and temporarily fix the top of the PVC pipe. Appropriate concrete is driven in from the outer wall, and when the height of the spacer PVC pipe between the three PVC pipes is exceeded, a vibrator is applied to lift the spacer PVC pipe between the three PVC pipes with a low specific gravity. Equalize aggregates. When placing the PVC pipe sideways and placing the concrete, 2 concrete holes in the concrete hole are buried, the PVC pipe is lifted up, 3 spacers between the PVC pipes and the possibility of air remaining in the PVC pipe and the aggregate around the PVC pipe There is a problem that does not equalize. Due to the stability of the overall strength of the different-diameter holed fish block, the protective concrete padding in the 2 concrete holes and the PVC pipe is set up, and the spacer between the 3 PVC pipes and the short PVC pipe are also set up and placed with sufficient dimensions. By using waste PVC pipes for all PVC pipes in this process, the first step of environmental improvement starts and more greenhouse gases are reduced.

Figure 8 Completion of the finished perth of the different diameter hole fish floor block, the improved Figure 5 irregularity collapse prevention type, Figure 6 partially reinforced pile reinforcement type, and Figure 7 multiple connection type, revetment and geology This can be selected in consideration of the carry-in route.

  FIG. 1 shows the laying plane of the saw blade type laying revetment method of the different diameter hole fish floor block of the present invention. By setting the surface g1 without holes at an acute angle e1 of approximately 60 degrees with respect to the water flow direction h1, the angle b1 of the square pillar is set. Interferes with the water flow direction h1 in the forefront, and an environment where the reverse flow c1 is easy to be made is prepared, and the water surface area into which oxygen can be taken up is increased. At the same time, since the surface on which the fish bed hole a1 is arranged is an obtuse angle f1 which becomes the back wall surface with respect to the water flow direction h1 of the surface g1 having no holes, the water flow direction h1 does not directly hit the fish bed hole a1, The fish hole a1 and the anchorage d1 that ensure the safety of underwater organisms can be created, and the probability that dust and dirt will enter the fish hole a1 is extremely low.

In this way, when waste PVC pipes, which are very difficult to process in the manufacturing stage, are used as a material for changing the usage and recycling as a protective material against friction deterioration inside the concrete hole, when used as a fish bed, it is a structure that prevents sediment from accumulating on a smooth wall. The longer the maintenance cycle is, the more it is used, it becomes a nest of various underwater organisms, leading to the reduction of greenhouse gases emitted in the material recycling process of waste PVC pipes. By using it for revetment construction, a strong revetment is secured, and at the same time, a river bank is created where a reverse flow in which dissolved oxygen continues to increase is ensured, and a space where fish can live safely is secured. It becomes a riverbank without.
In addition, the maintenance cycle of the revetment becomes longer due to the setting of different-diameter fish bed blocks in a shape that does not collect dirt and earth and sand.
