Wall Draingy device

I MPK7E02D31 / 02

The utility model relates to construction, namely, the installation of drainages around the existing foundations of buildings and structures and can be used to protect and empty the basements and basement floors of buildings and underground structures.

A drainage device is known, which consists of a drainage wall and a drainage system (collector). The draining wall is made of a composite of sand-gravel mixture slabs on a water-soluble binder, laid closely to the foundation. This device allows you to make plates outside the place of work, then transport them and ready to put in the design position. Under the influence of moisture, the binder of the plates dissolves, and the wall turns into a continuous drainage layer 1.

The disadvantages of this device include the need for a technological process for the manufacture of materials for such drainage, and the development of traps to create a drainage route for collecting and removing water is required.

The closest in technical essence to the proposed is the device of wall drainage, consisting of a drainage system, the collector of which is made in the form of drainage pipes placed with the building parallel to the walls of the foundation at the level of its base. It is connected to the drainage wells in the corners of the building by means of pipes passing through the foundation, with a drain filling filled under the floor of the submerged underground room (basement). The device also contains a drainage backfill made outside the building, on which backfill from the ground is laid, and a clay castle is made under the backfill. A waterproof blind area is placed on top of the backfill, and there is vertical waterproofing on the wall of the drainage room.

The depth of the drainage of such a device is greater than the depth of the foundation, which ensures a decrease in the level of groundwater below the bottom of the foundation and the floor of the drainable floor (basement), and this protects them from flooding 2.

The disadvantages of the device are the necessity of driving trenches along the foundation, the construction of drainage wells at a distance from the foundation, which is laborious and not always possible in urban areas, as well as the implementation of drainage backfill inside the building and the installation of the floor for drainage backfill.

The objective of the utility model is that, with the least laboriousness, using the existing sewer wells, to protect underground obstacles from flooding; buildings (basements, basement floors of buildings).

The problem is solved as follows:

Similarly to the prototype, the device contains a drainage backfill outside the building or structure, on which a backfill from the ground is laid on top, and a clay castle is located below it. A waterproof blind area is made on the back flap. There is vertical waterproofing on the wall of the drained underground building. The device also includes a drainage system, which includes a collector and pipes passing through the drainable wall of the underground premises and connected to the collector. But unlike the known device in the claimed collector is located inside the building and is made in the form of channels in the basement floor or other drained underground premises. In addition, this channel is placed with the possibility of forced pumping of water into the sewer network inside the building. The difference is also that the drainage filling is located above the floor level of the drained building premises and is connected to the pipes.

Thus, the claimed device differs from the known one in that:

the collector is made in the form of a channel in the floor of the drained room. This arrangement and implementation of the collector does not require additional routes for water removal and creates the ability to remove water directly into the sewer network, for example by pumping. In addition, it becomes possible to measure water inflow and the ability to monitor the state of drainage, its siltation;

The drainage backfill is made above the floor level of the underground room (basement) and is connected to pipes, which, with this arrangement of the drainage backlog, have an inclination towards the collector, which favors the flow of water into the collector. With such a depth of drainage backfill, the groundwater level is not up to the floor level of the room being drained, and moisture is removed unhindered through the pipes into the collector. The floor of the room to be drained become waterproof.

The proposed drainage device does not require deep trenches to be drilled along the perimeter of the building, simplifies the removal of water and allows for monitoring the state of drainage, i.e. with the least laboriousness to protect underground premises from flooding.

In fig. shows a diagram of a drainage device.

The device contains steel pipes 1, passed through an opening in the wall of the underground room 2, on one side connected to a drainage backfill 3 made of a gravel-sand mixture and laid in a clay lock (waterproofing) 4, and on top covered with backfill soil 5. The other side of the pipe 1 is connected by a guide tray 6, to the collector 7. The pipe 1 can be made longer and directly connected to the collector. The incoming water is removed to the sewer network by pump 8. To prevent soaking (humidification) of the underground room from the outside, a vertical waterproofing 9 was made from the bottom of the foundation 2 to the top of the waterproof pavement 10. t 1 The drainage device using the proposed method is performed in the following order: First a pit of the required depth is opened at the site of the water reduction, then in the existing wall of the underground room 2 below the groundwater level punch through holes Trom at least 20 mm with a slope with respect to the floor of the underground facilities. It is enough to carry out a slope from 5 to 15. Steel pipes 1 are installed in the holes. Then, vertical waterproofing 9 and installation of the clay castle 4 below the outer holes for pipes are performed. Next, drainage filling 3 is performed at the location of the pipes, i.e. above the floor level of the underground room, but below the groundwater level (ground water in the drawing) and make backfill 5 and blind area 10. In the basement of the building, drainage channel 7 and guide trays 6 from pipe 1 are installed. Install pump 8 of the required capacity for forced pumping water from collector 7 to the sewer network. The literature used in the preparation of the description 1.A.
