Abstract
Description
Technical Field
[0001] The invention relates to a drainage system for lowering the water level of an anti-floating device, in particular to a drainage system for lowering the water level of an anti-floating device used in an underground building. Background Art
[0002] With the development of economy and the continuous increase of urban population density, the development and application of underground space are becoming more and more extensive, especially for underground space structures with poor permeability such as rock, silt soil, clay soil and high anti-floating water level. The anti-floating problem of such buildings is becoming more and more prominent, and is affected by the flood season and strong rainfall in a short period of time, the groundwater level rises, and the drainage is not timely during the construction process, causing the raft foundation to float up under the action of water buoyancy, and the bottom plate to bulge and crack, and water seepage occurs. The underground buildings are seriously damaged, affecting the normal use of underground buildings. For example, an underground garage in Nanchang sank due to the increase of groundwater buoyancy, accompanied by cracks in some walls, causing more than 40 load-bearing columns to crack without reason. The phenomenon of underground garages being damaged by water buoyancy often occurs in rainy seasons. Summary of the invention
[0003] In view of the deficiencies in the prior art, the object of the present invention is to provide a drainage system for lowering the anti-floating defense water level which can discharge water above the drainage plane and can automatically drain water when the water level is higher than the warning water level.
[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:
[0005] A drainage system for lowering the water level of an anti-floating device, comprising a water collecting trough, which is lower than a drainage plane; a pressure-resistant chamber, which is arranged as a closed tank, with a bottom arranged in the water collecting trough and connected to the water collecting trough, and an upper part extending out of the drainage plane; a guide pipe, one end of the guide pipe extends into the pressure-resistant chamber, and the other end extends out to a certain height above the drainage plane; a drain valve, which is arranged at the bottom of the guide pipe and is higher than the drainage plane; a water level observation hole, which is arranged on the guide pipe; a pressure relief pipe, which is connected to the guide pipe and arranged in parallel, and an outlet extends to a drainage ditch; and an exhaust pipe, which is arranged at the upper end of the guide pipe.
[0006] Preferably, a pressure inspection cover is provided on the top of the pressure-resistant bin.
[0007] Preferably, at least one water level observation hole is provided.
[0008] Preferably, four water level observation holes are provided, namely, two normal water level observation holes, one high water level observation hole, and one warning water level observation hole.
[0009] Preferably, an alarm is arranged around the warning water level observation hole.
[0010] Preferably, the connection point between the pressure relief pipe and the diversion pipe is higher than the warning water level observation hole.
[0011] Preferably, a water filter is provided at the lower part of the pressure-resistant bin.
[0012] Preferably, a water stop plate is provided on the top of the water collecting tank outside the pressure-resistant warehouse.
[0013] Preferably, the flow guide pipe is provided with a valve.
[0014] The technical solution is a drainage system for lowering the water level of anti-floating defense, which includes a water collecting trough, which is lower than the drainage plane; a pressure-resistant chamber, which is arranged as a closed tank body, with the bottom arranged in the water collecting trough and connected to the water collecting trough, and the upper part extending out of the drainage plane; a guide pipe, one end of the guide pipe extends into the pressure-resistant chamber, and the other end extends out and is higher than the drainage plane by a certain height; a drain valve, which is arranged at the bottom of the guide pipe and is higher than the drainage plane; a water level observation hole, which is arranged on the guide pipe; a pressure relief pipe, which is connected to the guide pipe and arranged in parallel, and the outlet extends to the drainage ditch; an exhaust pipe, which is arranged at the upper end of the guide pipe. Normally, the water collection tank can be filled in daily applications. The water in the groundwater table will enter the pressure-resistant chamber under normal conditions. When the groundwater level rises, the groundwater enters the water collection tank, circulates through the pressure-resistant chamber, and guides the water into the diversion pipe. Maintenance personnel observe the water level elevation through the glass display in seasons with increased precipitation. When the groundwater level reaches the high water level observation hole, maintenance personnel can open the water valve to drain the groundwater naturally and lower the groundwater level. If the warning water level is reached, attention should be paid to discharge the rising water level in the underground space through both artificial and automatic pressure relief, that is, a large amount of groundwater should be discharged through the pressure relief pipe.
[0015] In the technical solution, a pressure inspection cover is arranged on the top of the pressure-resistant bin, through which maintenance personnel can observe the situation inside the pressure-resistant bin and perform maintenance.
[0016] The number of water level observation holes of the technical solution can be set as needed, at least one can be set, and four can be set as needed, namely two regular water level observation holes, one high water level observation hole, and one warning water level observation hole.
[0017] In this technical solution, an alarm is arranged around the warning water level observation hole, and an alarm is sounded when the water level reaches the warning water level, so that the maintenance personnel must perform manual drainage.
[0018] The connection point between the pressure relief pipe and the diversion pipe of the technical solution is higher than the warning water level observation hole. In this way, when the water level is higher than the warning water level and the maintenance personnel do not find it in time, the drainage system of the technical solution for lowering the anti-floating defense water level can automatically drain the water into the drainage ditch without any danger.
[0019] A water filter net is arranged at the bottom of the pressure-resistant warehouse of the technical solution, and the water filter net filters the water entering the water collection tank, and will not pollute or damage the drainage system that reduces the water level of the anti-floating protection device.
[0020] In the technical solution, a water stop plate is arranged on the top of the water collecting tank outside the pressure-resistant warehouse, so as to prevent water from buoying out through the drainage system that lowers the water level of the anti-floating protection device when the water level is high.
[0021] The guide pipe of the technical solution is provided with a valve, so that the valve can be closed when repairing or replacing accessories, and maintenance can be carried out normally when the water level is slightly higher.
[0022] The drainage system for lowering the water level of anti-floating defense facilities of this technical solution has a simple structure and solves major problems. It fundamentally solves the drainage problem of underground buildings such as basements and underground garages when the water level rises, and avoids the situation where basements and underground garages are flooded and can only be solved by pumping water.
[0023] On the basis of being in accordance with common knowledge in the art, the above-mentioned preferred conditions can be arbitrarily combined to obtain the embodiments of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
