[0033] In order to make the purpose, technical solution and advantages of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0034] The present application provides an anti-floating pressure relief and water precipitation device, such as Figure 1 , Figure 3 and Figure 4 As shown, the anti-floating pressure relief and dewatering device includes a plurality of dewatering wells 1, at least one water collection well 2, a water pump 3, and an anti-floating water pressure detection mechanism 4; the dewatering well 1 is used to be arranged below the foundation pit, and the dewatering well 1 is provided with a plurality of water inlet holes, so that groundwater can enter the dewatering well 1 from the water inlet holes, thereby achieving the lowering of the groundwater level below the foundation pit. The water collection well 2 is connected to the dewatering well 1 through a drainage pipe 5; the water pump 3 is arranged in the dewatering well 1, and is used to supply water from the dewatering well 1 to the water collection well 2; the anti-floating water pressure detection mechanism 4 is arranged in the foundation pit.

[0035] Specifically, the anti-floating water pressure detection mechanism 4 is used to monitor the gravity balance between the buoyancy of groundwater and the deadweight of the superstructure. When the detection value of the anti-floating water pressure detection mechanism 4 reaches or exceeds a predetermined threshold value, the buoyancy of groundwater is insufficient to balance the gravity of the deadweight of the superstructure, and the water pump 3 is turned on to supply the water in the precipitation well 1 to the collection well 2, so that the groundwater below the foundation pit is collected into the precipitation well 1 through the water inlet hole, thereby realizing a drop in the groundwater level and depressurizing the groundwater, thereby ensuring that quality problems such as structural damage and leakage will not occur due to water pressure during subsequent structural construction.

[0036] The present application cooperates with the anti-floating water pressure detection mechanism 4, the water pump 3, the precipitation well 1 and the water collection well 2, so that when necessary, the water in the precipitation well 1 can be supplied to the water collection well 2 through the water pump 3, so as to collect groundwater through the precipitation well 1 to dewater and relieve the pressure of the groundwater without setting a post-cast strip, thereby avoiding the risks of corrosion of the bottom plate and structural steel bars, leakage of the main structure, and water accumulation in the basement due to long-term precipitation before the sealing process of the post-cast strip of the basement, which greatly reduces the trouble caused by groundwater to the foundation pit construction and ensures that the structure will not be damaged due to water pressure during the subsequent structure construction.

[0037] In one embodiment of the present application, the anti-buoyancy water pressure detection mechanism 4 includes a pressure sensor, which is arranged at the bottom of the foundation pit and partially buried below the bottom of the foundation pit, so as to monitor the pressure below the foundation pit to determine the balance relationship between the buoyancy of groundwater and the gravity of the upper structure.

[0038] In one embodiment of the present application, the precipitation well 1 includes a cylinder 11 and a cone 132; the cylinder 11 is cylindrical; the axial direction of the cylinder 11 is vertically arranged, and both axial ends (i.e., the upper and lower ends) of the cylinder 11 are open; the cone 132 is arranged at the lower end of the cylinder 11 and is connected to the cylinder 11; the large diameter end of the cone 132 is connected to the cone 132; the water inlet hole is provided on the cone core and the cylinder 11.

[0039] Specifically, the cone 132 is placed at the lower end of the cylinder 11, so that the dewatering well 1 can be effectively inserted under the foundation pit through the conical structure of the cone 132, thereby improving the convenience of assembling the dewatering well 1 under the foundation pit.

[0040] In one embodiment of the present application, the plurality of precipitation wells 1 are arranged in a matrix, and the distance between two adjacent precipitation wells 1 in the same row in the matrix is ​​greater than or equal to 8 m.

[0041] In one implementation of this embodiment, Figure 3 As shown, every six precipitation wells 1 constitute a precipitation well 1 unit, and each precipitation well 1 unit is connected to two collection wells 2; each precipitation well 1 unit is arranged in an array of two rows and three columns, and the row spacing of the precipitation wells 1 in the array is greater than 10m, and the two collection wells 2 are distributed on both sides of the precipitation well 1 unit along the row direction of the array, and all precipitation wells 1 are connected.

[0042] In one embodiment of the present application, a filter screen is provided at the water inlet to filter out sediment and reduce the sediment entering the precipitation well 1.

[0043] In one embodiment of the present application, the cylinder 11 and the cone 132 are an integrally formed structure to enhance the strength between the cylinder 11 and the cone 132 , thereby ensuring the stability of the precipitation well 1 placed below the foundation pit to collect groundwater.

[0044] In one embodiment of the present application, Figure 2 As shown, the precipitation well 1 further includes a cover 13 , which is detachably connected to the upper end of the cylinder 11 and is used to seal the upper end opening of the cylinder 11 ; the drainage pipe 5 is connected to the cover 13 .

[0045] The sealing cover 13 seals the upper opening of the cylinder 11 and is connected to the drainage pipe 5, so that the precipitation well 1 can only collect groundwater through the water inlet hole and supply water to the water collection well 2 through the drainage pipe 5, thereby stabilizing the water pressure in the precipitation well 1 and ensuring that the groundwater outside the precipitation well 1 can smoothly enter the precipitation well 1 through the water inlet hole.

[0046] The sealing cover 13 includes a cover body 131 and a connecting portion 12; the cover body 131 is detachably connected to the cylinder body 11; the connecting portion 12 is located above the cover body 131; the connecting portion 12 is conical, and the small diameter end of the connecting portion 12 is connected to the drain pipe 5, and the large diameter end of the connecting portion 12 is connected to the cover body 131.

[0047] The connecting portion 12 is used to guide the water flow, making it easier to discharge the water in the precipitation well 1 into the water collection well 2 through the drainage pipe 5. When the cover 13 is connected to the cylinder 11 and closes the upper end opening of the cylinder 11, the pressure difference between the inside and outside of the precipitation well 1 can be guaranteed, thereby ensuring that the groundwater outside the precipitation well 1 can smoothly enter the precipitation well 1 from the water inlet hole to precipitate and depressurize the groundwater without setting up a post-cast strip, avoiding the risks of long-term precipitation before the closure process of the post-cast strip in the basement, corrosion of the bottom plate and structural steel bars, leakage of the main structure quality, and water accumulation in the basement, greatly reducing the trouble caused by groundwater to the foundation pit construction, and ensuring that the structure will not be damaged due to water pressure during the subsequent structural construction.

[0048] In one embodiment of the present application, Figure 2 As shown, the anti-floating pressure relief and water drainage device further includes a pressure relief valve 6 , which is disposed at one end of the drain pipe 5 close to the sealing cover 13 and is used to control the on-off of the drain pipe 5 .

[0049] When the detection value of the anti-floating water pressure detection mechanism 4 does not reach a predetermined threshold value, the water pump 3 and the pressure relief valve 6 can be turned off to ensure that the water path between the precipitation well 1 and the water collection well 2 is shut off; when the detection value of the anti-floating water pressure detection mechanism 4 reaches or exceeds a predetermined threshold value, the water pump 3 and the pressure relief valve 6 can be turned on to ensure that the water path between the precipitation well 1 and the water collection well 2 is connected, thereby vacating the precipitation well 1, allowing groundwater to enter the precipitation well 1, and realizing precipitation and pressure relief of groundwater.

[0050] In one embodiment of the present application, the anti-floating pressure relief and water discharge device also includes a first flange ring 7 and a second flange ring 8; the first flange ring 7 is arranged on the periphery of the cover 13 and is located at one end of the cover 13 close to the cylinder 11; the second flange ring 8 is arranged on the periphery of the cylinder 11 and is located at one end of the cylinder 11 close to the cover 13; the first flange ring 7 and the second flange ring 8 are detachably connected.

[0051] In this embodiment, the sealing cover 13 and the cylinder body 11 can be connected by the cooperation between the first flange ring 7 and the second flange ring 8; the cooperation between the first flange ring 7 and the second flange ring 8 can increase the contact area between the sealing cover 13 and the cylinder body 11, and improve the accuracy of the alignment between the sealing cover 13 and the cylinder body 11.

[0052] In one implementation of this embodiment, the first flange ring 7 and the second flange ring 8 are detachably connected by screws. The first flange ring 7 and the second flange ring 8 are symmetrical to each other; Figure 5 As shown, a plurality of threaded mounting holes 71 are provided on the first flange ring 7, and the diameter of the threaded mounting holes 71 is 1 / 5 of the outer diameter of the first flange ring 7; the plurality of threaded mounting holes 71 are evenly arranged along the circumferential direction of the first flange ring 7, and the corresponding central angle between two adjacent threaded mounting holes 71 is 22.5°, so as to ensure the stability of the connection between the first flange ring 7 and the second flange ring 8 while ensuring the self strength of the first flange ring 7.
