Description

Basement drainage structure

Technical Field

The utility model relates to a basement waterproof construction specifically is a basement drainage structure.

Background

Along with the continuous development of city construction, the construction of high-rise buildings and super high-rise buildings is more and more, the depth and the number of floors of basements are also continuously increased, the construction projects with underground civil air defense, underground shopping malls, underground parking lots and the like are more and more common, however, the leakage phenomena of the basements caused by the construction projects are increased, the quality of the construction projects is seriously influenced, and great inconvenience is brought to the normal use and management of the basements.

Due to the fact that construction is careless or underground water pressure is large, water leakage is prone to occurring in buildings with the depth of the basement below the underground water level, accumulated water is accumulated in one place due to water leakage, and therefore the basement drainage structure is provided.

SUMMERY OF THE UTILITY MODEL

1. Problems to be solved

Problem to exist among the prior art, the utility model aims at providing a basement hydrophobic structure, communicate each other through communicating pipe between the sump pit, make in the sump pit too late exhaust ponding can disperse flow in the sump pit on every side, accelerate drainage speed, thereby avoided overflowing ponding pile up in one and cause the harm to ground too much, and laid the grid net between rubble supporting layer and the hydrophobic layer, thereby make ponding on the seepage can evenly distributed, avoid piling up in one, promote water-proof effects, thereby the problem of mentioning in the above-mentioned background story has been solved.

2. Technical scheme

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides a basement drainage structure, includes basement bottom plate, basement roof and water collection well, set up a plurality of evenly distributed's sump pit on the basement bottom plate, and the lower terminal surface fixed intercommunication of sump pit has the drain pipe, the delivery port and the escape canal intercommunication of drain pipe bottom, the hydrophobic layer has been laid to the upper surface of basement bottom plate, and the rubble supporting layer has been laid to the hydrophobic layer upper surface, and the basement roof has been laid to rubble supporting layer upper surface.

As a further aspect of the present invention: and a grid net is laid between the gravel supporting layer and the hydrophobic layer.

As a further aspect of the present invention: the water collecting wells are communicated with each other through communicating pipes.

As a further aspect of the present invention: and both ends of the communicating pipe are connected with filter screens.

As a further aspect of the present invention: the thickness of the gravel supporting layer is at least 100 mm.

Compared with the prior art, the beneficial effects of the utility model are that:

1. when the seepage takes place in the ground, ponding can be piled up in the sump pit, ponding in the sump pit passes through the timely discharge of drain pipe, and communicate each other through communicating pipe between the sump pit, make in the sump pit too late during discharged ponding can the dispersion flow in the sump pit on every side, accelerate drainage speed, thereby the ponding of having avoided overflowing is piled up in one and is too much to cause the harm to ground, and laid the grid net between rubble supporting layer and the hydrophobic layer, thereby make ponding on the seepage can evenly distributed, avoid piling up in one too much, promote water-proof effects.

2. The utility model discloses both ends at communicating pipe all are connected with the filter screen to reduce the probability that communicating pipe is blockked up, makeed to keep the connected state between the sump pit, the dispersion ponding of being convenient for has promoted the water-proof effects of device.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, in the embodiment of the present invention, a basement drainage structure includes a basement bottom plate 8, a basement top plate 6 and a water collection well 1, a plurality of water collecting wells 1 which are uniformly distributed are arranged on the basement bottom plate 8, the water collecting wells 1 are used for collecting accumulated liquid leaked underground, and the lower end surface of the water collecting well 1 is fixedly communicated with a drain pipe 5, the water outlet at the bottom end of the drain pipe 5 is communicated with a drainage ditch, thereby facilitating the timely discharge of the residual effusion, avoiding the accumulation phenomenon, improving the anti-seepage effect, the upper surface of the basement bottom plate 8 is paved with the hydrophobic layer 2, the upper surface of the hydrophobic layer 2 is paved with the gravel supporting layer 4, the gravel supporting layer 4 is used for supporting the basement top plate 6, the stability of the ground is improved, and the thickness of rubble supporting layer 4 is 100mm at least to guarantee the support effect, basement roof 6 has been laid to rubble supporting layer 4 upper surface.
