Abstract
Description
Technical Field
[0001] This application belongs to the field of construction dewatering technology, specifically relating to a dewatering anti-buoyancy pressure relief device and construction structure. Background Technology
[0002] Underground engineering projects are frequently threatened by groundwater buoyancy during construction and use. Dynamic changes in groundwater levels can easily cause structural uplift, foundation cracking, and beam-column joint damage, seriously affecting the safety and durability of buildings. Especially in highly permeable silty and sandy soil strata, uncalculated anti-buoyancy designs or inappropriate water level values can lead to major accidents. Therefore, scientifically assessing buoyancy loads and implementing dewatering and anti-buoyancy measures are necessary prerequisites for ensuring the stability of underground engineering projects.
[0003] During current construction, necessary measures for dewatering are required. However, different dewatering devices need to be designed specifically for different locations or structural forms. Furthermore, existing dewatering devices have poor water filtration effects, which can easily cause pipe blockage and affect the dewatering effect. In other words, existing dewatering devices lack flexibility, cannot be adjusted according to construction needs, and the quality of dewatering cannot be guaranteed. Utility Model Content

[0007] Furthermore, both the water filter pipe and the pressure relief pipe are galvanized pipes.
[0008] Furthermore, the filter plate is a PVC water grate.
[0009] Furthermore, the inner side of the filter plate is provided with a retaining ring, which is inserted into and locked onto the water inlet end of the filter pipe.

The structure also includes the aforementioned pressure relief device for preventing buoyancy during dewatering. The pressure relief device is located inside the raft. The wellhead of the dewatering well is equipped with a well cap. The inlet end of the filter pipe extends through the well cap into the dewatering well. The pressure relief valve extends into the collection well.
[0016] Furthermore, several dewatering wells are arranged, and the pressure relief pipes of several dewatering wells converge into a collection well.
[0017] A construction structure for preventing buoyancy during precipitation includes a precipitation trough, a raft, and a collection well.

In addition, the pressure relief valve can be used to regulate the precipitation process and flexibly switch between pressure relief and water release or valve closure and water storage to meet the needs of different construction periods.
[0021] (2) The components of the device are connected by bolts, which allows for flexible assembly or replacement of the device.

Detailed Implementation
[0028] The present application will be further described below with reference to specific embodiments and accompanying drawings.
[0029] Example 0
[0030] refer to Figures 1-4 As shown, a pressure relief device for preventing buoyancy during precipitation includes a filter pipe 1, a filter plate 2, a filter particle filling layer 3, a first conversion joint 4, a pressure relief pipe 5, a second conversion joint 6, and a pressure relief valve 7.
[0031] The filter pipe 1 is used to house the filter material so that the groundwater can be filtered and discharged later. The inlet end of the filter pipe 1 is equipped with a filter plate 2, which is a plate-shaped structure with filter holes. The groundwater is initially filtered through the filter plate 2 to block large stones, soil and other debris.
[0032] The filter pipe 1 is equipped with a filter particle filling layer 3, which is a layered structure formed by the accumulation of filter particles. It forms infiltration gaps within the layer, allowing for secondary infiltration of groundwater and blocking small volumes of silt and other particles. This double-layer filtration effectively filters groundwater and prevents blockage of the internal pipes.
[0033] The outlet end of the filter pipe 1 is connected to the first conversion joint 4, which is connected to the pressure relief pipe 5. The first conversion joint 4 is used for transition between large and small pipe diameters, so as to transition the large-diameter filter pipe 1 to the small-diameter pressure relief pipe 5. The pressure relief pipe 5 is used for drainage, so as to drain the groundwater at the filter pipe 1 to other locations.
[0034] The pressure relief pipe 5 is connected to the second conversion joint 6, which in turn is connected to the pressure relief valve 7. The second conversion joint 6 is used for transitional connection between the pipe and the valve, allowing the pipeline to transition to the valve. The pressure relief valve 7 controls whether the entire device is connected or not, thereby regulating the pressure relief and drainage status.
[0035] The filter pipe 1 is a DN100 galvanized pipe, the first conversion joint 4 is a DN100*25 conversion joint, the pressure relief pipe 5 is a DN25 galvanized pipe, and the second conversion joint 6 is a DN25*15 conversion joint.
[0036] The filter plate 2 is a PVC water grate. The inner side of the filter plate 2 is provided with an integrated insert ring. The insert ring is inserted and locked into the water inlet end of the filter pipe 1, so that the filter plate 2 can be installed in the filter pipe 1. Due to the blocking effect of the filter plate 2, the filter particle filling layer 3 is also blocked in the filter pipe 1.
[0037] The filter granule filling layer 3 is a pebble filling layer, which is low in cost and easy to obtain. It can effectively filter muddy water, allowing clear water to pass through while mud and sand are retained in the tortuous and narrow channels.
[0038] The filter pipe 1 is connected to the first conversion joint 4, the first conversion joint 4 to the pressure relief pipe 5, the pressure relief pipe 5 to the second conversion joint 6, and the second conversion joint 6 to the pressure relief valve 7 by threaded connections. Bolt connections allow for detachable connections between components, enabling the adjustment and replacement of component specifications according to different site conditions, making the device flexible and adaptable to various operating scenarios. For example, the length and shape of the pressure relief pipe 5 can be adjusted.
[0039] The pressure relief valve 7 is a faucet, which is low in cost and easy to purchase. Operators can turn the faucet to release or turn off the water, making it quick and flexible to operate.
[0040] Example 1

The pressure relief device is located inside the wall 8 and is applied to the exterior wall of the basement. It is installed 50cm from the top of the raft slab and is tied (welded) together with the reinforcing steel bars and poured together with the main structure.
[0042] The inlet end of the filter pipe 1 extends to the outside of the wall 8, protruding 70cm-100cm beyond the outer side of the wall, to release the groundwater outside the wall 8. The pressure relief valve 7 extends to the inside of the wall 8, that is, the groundwater on the outside is released to the inside, realizing the anti-buoyancy of the rainwater on the outside of the basement.
[0043] The pressure relief pipe 5 is a straight pipe, and a water-stop ring 15 is provided on the pressure relief pipe 5. The water-stop ring 15 is used to block water in the direction of the pressure relief pipe 5 to prevent water from seeping along the pipe direction.
[0044] Example 2
[0045] refer to Figure 2 and Figure 4 As shown, a construction structure for preventing buoyancy during precipitation includes a precipitation well 9, a raft 11, and a collection well 12. The precipitation well 9 is located at the bottom of the raft 11. The structure also includes a pressure relief device for preventing buoyancy during precipitation as described in Example 1. The pressure relief device is located inside the raft 11 and installed at the bottom of the raft 11. The raft 11 is located on the foundation 16.
[0046] The dewatering well 9 extends into the raft slab 11, meaning the wellhead of the dewatering well 9 is higher than the bottom surface of the raft slab 11. A well cap 10 is installed at the wellhead of the dewatering well 9 to cover and seal the wellhead. The pressure relief device is fixed to the well cap 10 for stable installation. The pressure relief pipe 5 uses a bent pipe to ensure vertical and then horizontal connectivity.
[0047] The inlet end of the filter pipe 1 extends through the well cap 10 into the dewatering well 9, and the pressure relief valve 7 extends into the collection well 12. Several dewatering wells 9 are arranged, and the pressure relief pipes 5 of several dewatering wells 9 converge into the collection well 12, thereby filtering the groundwater in several dewatering wells 9 and then storing it together in a collection well 12 for discharge.
[0048] Example 3
[0049] refer to Figure 3 and Figure 4 As shown, a construction structure for preventing buoyancy during precipitation includes a precipitation trough 13, a raft 11, and a collection well 12. The precipitation trough 13 is located at the bottom of the raft 11. It also includes a pressure relief device for preventing buoyancy during precipitation as described in Example 1. The pressure relief device is located inside the raft 11 and installed at the bottom of the raft 11. The raft 11 is located on the foundation 16.
[0050] The opening of the rain trough 13 is flush with the bottom surface of the raft 11. A cover plate 14 is provided at the opening of the rain trough 13 to block and seal the opening. The pressure relief device is fixed to the cover plate 14 for stable installation. The pressure relief pipe 5 is a bent pipe to ensure vertical and then horizontal connectivity.
[0051] The inlet end of the filter pipe 1 extends through the cover plate 14 into the dewatering well 9, and the pressure relief valve 7 extends into the collection well 12. Several dewatering troughs 13 are arranged, and the pressure relief pipes 5 of several dewatering troughs 13 converge into the collection well 12, thereby filtering the groundwater in several dewatering troughs 13 and then storing it together in a collection well 12 for discharge.
