Description
Technical Field
The utility model relates to a device of water level of defence is resisted floating in control basement belongs to basement anti technical field that floats.
Background
The anti-floating problem of the basement bottom plate must be considered when the basement is designed and constructed. The anti-floating defense water level refers to the highest water level of underground water possibly encountered by the building engineering when the construction period and the service life meet the anti-floating defense standard, or the underground water level of the maximum buoyancy possibly received by the bottom surface of the underground structure bottom plate when the building engineering meets the worst working condition combination of the anti-floating defense standard in the construction period and the service life according to static conversion.
The anti-floating defense water level is provided, and a reasonable water level is provided according to the actual water head condition in the geological exploration process and the regional experience judgment by a geological exploration unit. Because the underground water level is greatly influenced by seasons and is greatly related to a groundwater replenishment mode, the difficulty of providing an economical and safe anti-floating water level by a geological exploration unit in the early stage of a project is high. Generally speaking, the anti-floating defense water level provided by a geological exploration unit adopts an empirical method, namely, the anti-floating water level of a basement is 1-1.5m below the outdoor ground.
The anti floating water level of seting up defences that the unit of prospecting provided can generally satisfy the anti superficial safety problem of project. However, the water level of different basements varies greatly, and the influence of underground soil layers, the source of underground water supply, the infiltration of surface water, the drainage condition of underground water, the construction process and the like all have great influence on the actual water level of the basements.
Therefore, in the basement anti-floating design, the owner wants to reduce the anti-floating water level through some measures to obtain good economic effect. At present, a water drainage depressurization method is generally adopted, and communicated water filter pipes, water collecting wells, sedimentation tanks and the like are arranged under a basement bottom plate, so that water drainage facilities are added, and the water drainage amount is greatly increased; it mainly has the following problems:
1. the drainage elevation is positioned below the basement bottom plate, and the submersible pump needs to pump water as long as water is positioned below the basement bottom plate, so that the operation time of the submersible pump is long, and equipment is easy to lose;
2. the groundwater level is lowered to the position below the basement bottom plate, the groundwater in the peripheral area is affected, and ground settlement, collapse and the like can be caused;
3. more additional drainage facilities are provided, the workload and the construction cost are increased, and the maintenance cost is increased.
Due to the problems, the water drainage depressurization method is difficult to apply in practical engineering and has limited use scenes.
For a scene that the anti-floating defense water level is higher than the basement bottom plate and the surface water changes greatly, an effective and economic anti-floating defense water level control scheme is needed.
SUMMERY OF THE UTILITY MODEL
In order to control effectively and resist floating and defend the water level, the utility model provides a device of water level is defended to anti floating of control basement, concrete technical scheme as follows.
The utility model provides a device of anti floating defence water level of control basement, the basement includes basement bottom plate and basement side wall, its characterized in that: a water collecting groove is formed in the edge of the basement bottom plate, and a first through hole is formed in the side wall, close to the basement side wall, of the water collecting groove; the device is characterized by further comprising an inverted U-shaped pipe and a drainage pump arranged in the water collecting groove, one end of the inverted U-shaped pipe is communicated with the first through hole, and the other end of the inverted U-shaped pipe faces towards the water collecting groove.
By adopting the technical scheme, the vertex of the inverted U-shaped pipe is the designed anti-floating defense water level, when the water pressure at the side wall of the water collecting groove exceeds the designed anti-floating pressure of the basement bottom plate, water below the basement bottom plate can flow into the water collecting groove through the inverted U-shaped pipe, and when the water pressure at the side wall of the water collecting groove does not exceed the designed anti-floating pressure of the basement bottom plate, the water below the basement bottom plate cannot be discharged into the water collecting groove from the inverted U-shaped pipe; the water in the sump recess may be drained by a drain pump. The first through-hole of recess that catchments sets up on the lateral wall that is close to the basement side wall, and this is particularly favorable to discharging infiltration's surface water, if the below of a large amount of surface water along basement side wall infiltration to basement bottom plate in flood season, if can not in time discharge probably cause destruction for basement bottom plate.
Furthermore, the water collecting grooves are arranged along the extension direction of the side wall of the basement at intervals. Set up a plurality of recesses that catchment, every recess that catchments all is provided with the inverted U-shaped pipe that corresponds, is convenient for like this float and sets up water level control to many places edges of basement bottom plate.
Furthermore, the side wall of the water collecting groove provided with the first through hole is positioned right below the side wall of the basement. This is beneficial to the first time discharge of the surface water seeping down beyond the anti-floating prevention water level.
Furthermore, a second through hole is further formed in the side wall, close to the side wall of the basement, of the water collecting groove, and the second through hole is connected with a water level recorder. Through setting up this water level record appearance, can monitor the water pressure of this lateral wall department, be convenient for verify the normal work of the U-shaped pipe of falling.
Further, the drain pump is preferably an automatic drain pump. When the water in the water collecting groove reaches a certain height, the automatic draining pump drains water automatically, which is beneficial to improving the automation level.
The utility model discloses a control basement anti floating defence water level provides a comprehensive, comprehensive solution. The advantages are as follows:
1. through the setting of the inverted U-shaped pipe, the basement is prevented floating and is prevented the water level. When the outdoor underground water level is higher than the top of the inverted U-shaped pipe, the water collecting groove begins to collect redundant water from the inverted U-shaped pipe, and the drainage pump begins to work; when the outdoor underground water level is lower than the top of the inverted U-shaped pipe, the drainage pump does not need to be started; the water discharge can be greatly reduced; a large amount of water can be consumed by the infiltration. Only when the rainwater season is in a rain season, the water is drained through the drainage pump when the water quantity is large.
2. The water level of the surrounding underground water is prevented from being too low, the hydraulic gradient can be reduced, fine particles in a soil layer are reduced and taken away by water flow, and water and soil loss is avoided.
3. The top elevation of the inverted U-shaped pipe can be controlled through design, and the inverted U-shaped pipe is safe and economical.
