Description

T-shaped retaining wall concrete block

technical field

The utility model relates to the field of building masonry materials, in particular to a T-shaped concrete block for retaining walls.

Background technique

Concrete block is a new type of building masonry structure material that does not use clay as raw material and does not need to be fired to shape. All of them are of great significance, and they are environmentally friendly and energy-saving new building materials that countries all over the world are actively promoting and developing.

In recent years, my country has also begun to choose to use concrete blocks as protection projects such as roadbeds and slopes on both sides of railways and highways, dams and cofferdams of rivers, rivers, lakes, reservoirs, and embankments of urban landscape waters. Building structural material for building retaining wall masonry.

In geotechnical engineering, the application of retaining walls has a considerable history, mainly to resist the effect of earth pressure and prevent the sliding and instability of slope and embankment soil. ``

Most of the traditional retaining wall structures only consider the function and effect of retaining soil, while ignoring the effects such as flexibility, aesthetics, convenient construction and economy.

At present, my country can provide optional concrete block products for the construction of retaining walls. Most of them are concrete blocks commonly used in construction projects. They are usually connected and fixed by concrete mortar. The special functional environment and technical requirements of earth walls. When the retaining wall encounters ordinary natural phenomena such as uneven settlement, heavy rain erosion, long-term flooding, continuous and long-term beating of waves, etc., the masonry of the retaining wall may be damaged such as loosening, displacement, arching, and collapse. If the protective effect is lost, it may even cause serious accidents such as roadbeds, slopes, embankments and other substrates being exposed and collapsed.

Contents of the invention

The purpose of the utility model is to provide a T-shaped concrete block for retaining walls with simple and reasonable structure, easy manufacture, firmness and durability, convenient construction and beautification of the environment.

The purpose of this utility model is achieved in that the concrete block of the retaining wall includes a block body in the shape of a "T", the top surface of the block body is provided with a U-shaped tension groove, and the block body The front side of the block is a vertical smooth plane with a trapezoidal groove in the middle, and the shoulders on the left and right sides of the main body of the block have a plurality of convex ribs arranged in parallel evenly in a semicircle, and the shoulders on the left and right sides are A plurality of protruding ribs on the upper part are matched with each other, the left side and the right side of the block body are curved planes with a vertical and smooth transition, and a rectangular groove is symmetrically arranged on the left side and the right side.

The utility model has the following advantages and positive effects:

1. Convenient and fast construction

Compared with the traditional retaining wall structure, the retaining wall block of the utility model has great advantages in convenient construction, and can double the construction progress and project quality. A team of three to four skilled workers can construct a wall of 20 to 40 square meters a day. The main body of the block is produced by a modern factory with the same size and shape. Masonry and anchor bolts, fast speed and short construction period. The unique self-interlocking rear edge structure of the retaining wall blocks ensures that the position of each block is accurate and the entire wall is neat; the requirements for the foundation are low, usually no special treatment is required, and the amount of excavation is small. Under normal circumstances, it is enough to ensure that the foundation soil has sufficient compactness and set a well-tamped graded crushed stone or plain concrete cushion of ≥150mm; 

2. Beautiful and natural

The utility model is a retaining wall block with both functionality and landscape, which is produced in a modern factory and has various colors, surface shapes, textures and textures. It can also be specially designed according to environmental requirements to meet the requirements of engineering diversity; the rough surface texture of the retaining wall blocks provides a natural and elegant landscape effect and a comfortable visual sense; each independent retaining wall block unit is staggered up and down , and the unique wall formed by gradually retreating and offsetting has more vitality and freshness, and can better integrate into the surrounding buildings, forming a harmonious and comfortable urban and living environment; 

3. Ecological and environmental protection

The blocks of the retaining wall of the utility model can be built vertically, save about three times of land resources compared with the traditional slope protection wall, and at the same time ensure large-area greening. The block wall of the retaining wall is a breathable wall, and water, air and other substances circulate naturally to ensure ecological protection;

4. Flexible structure, safe and reliable

The blocks of the retaining wall of the utility model are relatively independent and free, and have relatively high adaptability and self-adjustment ability for small-scale foundation subsidence or short-term extraordinary load combinations such as earthquakes and high groundwater levels; The self-embedded structure between blocks can effectively transmit lateral force from top to bottom to increase the shear resistance of the wall; the wall naturally forms a specific inclination, which is safer and firmer;

5. Durable material

The retaining wall block of the utility model is formed under strict quality control by hydraulic vibration on a modern production line, and is a high-strength, high-density, high-quality concrete block after steam curing, with extremely high compressive strength and impact resistance, it will not split or corrode; the high strength and low water absorption of the retaining wall block make it have a very high freeze-thaw resistance; the main body of the block is made of natural mineral pigments and the whole body is made of Does not fade in the environment;

6. Strong practicability

The earth retaining wall blocks of the utility model have no special requirements on topographic conditions, and can be safely used in any places where earth retaining is required, such as gardens, slope protection, dike protection, expressways, overpasses, etc. The size and weight of the retaining wall blocks allow construction in places with inconvenient traffic without the need for lifting machinery; the flexible wall body can drain water quickly, reduce and eliminate the water pressure behind the wall, especially suitable for river retaining wall slope protection; it can be built into Ladder type, inner right angle, outer right angle, inner circular arc, outer circular arc or other special shapes required by landscape design or terrain conditions; the height of a single wall can range from 0.3 meters to 15 meters, and it can be built by adopting the ladder type any height;

7. Cost economy

The utility model retaining wall blocks have low requirements on the foundation, are suitable for poor foundations such as weak and silt, and reduce expensive foundation treatment costs such as foundation piling and soil replacement. If necessary, the width of the reinforced soil can be widened to effectively reduce the foundation stress under the wall; the main surface layer of the retaining wall block does not require any surface treatment or secondary decoration; most of the composition material of the entire wall is backfill soil , can obtain local materials and save building materials; the construction progress is fast, which can save a lot of labor costs; it has high durability, long service life, and no maintenance in the later period; it is easy to disassemble and can be reused when necessary.
