Technical Field
The invention relates to a drainage method for an underground garage, in particular to a drainage method for a top plate of a non-gradient garage and application thereof.
Background
At present, underground garages are mainly divided into large-chassis ground garages and common independent ground garages. Because the large-chassis ground reservoir has a higher land utilization rate than an independent ground reservoir, and the independent ground reservoir is very easy to cause the situations of road surface collapse, sinking and pipeline fracture due to the fact that the tamping requirements of backfill on the upper part of a top plate of the ground reservoir and backfill between a main building and the ground reservoir are different and the situations of long-term uneven settlement are easily caused, most developers adopt the large-chassis ground reservoir at present. However, due to the large span of north and south and east and west of the large-chassis ground reservoir, the difficulty of structure slope finding is large, the siphon type drainage has high cost and unobvious efficiency, the contact surface of soil and the ground reservoir is larger than that of a common independent ground reservoir, and the water leakage phenomenon is easy to occur after the ground reservoir operates for a period of time.

Furthermore, the drainage well is arranged in planting soil between the lower part of the vegetation and the upper part of the top plate of the ground reservoir, the top of the drainage well is connected with a well cover, and the well cover is positioned at the vegetation; a floor drain communicated with the drainage well cavity is arranged on a top plate of the ground reservoir positioned in the drainage well cavity, a ladder stand is arranged on the inner side of the well wall of the drainage well, a water through hole is formed in the well wall at the bottom of the drainage well, geotextile is covered on the well wall provided with the water through hole, fillers of pebbles, gravels and coarse sand are sequentially filled on the outer side of the geotextile from near to far, and the height of the fillers is higher than that of the geotextile; and the bottom of the drainage well is coated with waterproof paint.
Rainwater and outdoor greening watering are absorbed by evaporation and ground vegetation, residual accumulated water can permeate through planting soil on the upper portion of a top plate of the ground reservoir, the water and soil are filtered through coarse sand, gravel, pebbles and geotextile around a drainage well, the problem that the planting soil on the upper portion of the top plate of the ground reservoir is washed by long-time rainwater to cause water and soil loss is avoided, the water and soil are drained into the well through water through holes formed in the bottom of the drainage well, the bottom of the drainage well is subjected to waterproof treatment to prevent the accumulated water drained into the well from permeating into the ground reservoir around a floor drain opening, the accumulated water is led into a nearby water collecting pit in the ground reservoir through a drainage pipe communicated with the floor drain, and the accumulated water is drained into. The steel crawling ladders arranged around the well wall are used for cleaning the drainage well regularly according to the depth requirement of the drainage well.
In addition, the invention also provides application of the non-gradient ground garage top plate drainage method in large-chassis ground garage top plate drainage.
Compared with the prior art, the invention has the following beneficial effects:
the method has good drainage effect, so that rainwater accumulated in the earth covering of the top plate of the underground reservoir and greening watering can be drained in time, and the problems of ground subsidence and water leakage in the underground reservoir caused by long-term water accumulation in the earth covering of the top plate of the underground reservoir are avoided.
The ground reservoir blocked by the traditional plugging agent in the same area is easy to cause wall surface pollution in the construction process, and the building structure is easy to be influenced due to the large number of holes. Because the traditional plugging agent belongs to chemical products and is easy to age, plugging needs to be carried out again at intervals of 3-5 years, and the problem of water leakage cannot be effectively solved at one time.
Compared with a ground reservoir blocked by using the traditional plugging agent in the same area, the method can save 402 ten thousand yuan, and has good economic benefit and social benefit.
