Description

Technical Field

[0001] This invention relates to the field of anti-buoyancy foundation treatment technology, specifically to a groundwater collection and drainage system for anti-buoyancy of basement floor slabs. Background Technology

[0002] Anti-buoyancy design is a crucial aspect of basement design. Current measures for addressing buoyancy in practical engineering include dewatering, ballast methods, and the installation of anti-uplift piles or anti-buoyancy anchors. Each method has its advantages, disadvantages, and applicability. Although relevant building codes have explored this area, the regulations are not clear enough, there is a lack of unified understanding of buoyancy design, the current anti-buoyancy design concept is incomplete, a clear systematic theory has not yet been established, and commonly used anti-buoyancy design models and calculation methods tend to be overly simplified. When it rains and the groundwater level rises, the basement floor slab experiences upward pressure, gradually rising until the pressure exceeds the slab's withstand limit, at which point the basement floor slab bulges and cracks.

[0003] To address the problems caused by basement uplift, methods such as ballast, anti-uplift piles, or anti-uplift anchors are commonly used. However, these methods are costly and time-consuming. To overcome these issues of high cost and low efficiency, existing technologies also include installing pressure relief wells on the basement floor slab to pump out groundwater and reduce uplift caused by groundwater beneath the slab. While this method effectively relieves pressure and reduces construction costs, the seepage pipes beneath the basement floor slab become clogged over time due to the accumulation of silt or other sediments. Consequently, the pressure relief wells cannot adequately collect water from below the basement floor slab, still leading to problems with the basement floor slab. Summary of the Invention

[0031] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention. As used herein, the terms "parallel" and "perpendicular" are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors.

[0032] The following is in conjunction with the appendix Figures 1 to 10 The water collection system under the basement floor slab of the present invention will be described in detail below:

[0033] The basement floor is easy to be affected by the underground water floating to cause certain diseases, such as the basement floor cracking, arching, and even more, the basement bearing column cracking or breaking, so the anti-floating design of the basement is the key point of the actual construction. The reason for the basement floor floating is that the rainwater outside seeps into the basement floor through the building peripheral side wall position and seeps into the basement floor below the building side wall, and a part of the underground water below the basement floor also flows in. With the accumulation of underground water, the underground water produces floating force on the floor of the building, so the above diseases are easy to cause. The larger the span of the basement is, the more obvious the above diseases are. The gravity of the building above the basement can resist the floating force below the basement floor. However, the larger the span of the empty area between buildings is, the more shear force the basement floor below the empty area will produce, and thus the diseases caused by the floating force of the basement are easy to cause. In the prior art, the anti-floating pile or anti-floating anchor rod is used to eliminate the floating force of the basement floor, and the anti-floating pile or anti-floating anchor rod needs to be densely arranged. However, in the actual construction, the cost is high, and a large amount of foundation construction work needs to be done before the basement construction, which leads to low construction efficiency. Therefore, the method of collecting and pumping the underground water to eliminate the floating force below the basement floor is proposed. However, in the actual collection of underground water, the stone with multiple voids is used to fill, and the permeation pipe is embedded in the stone. However, with the increase of the service life, the permeation pipe and the stone are easy to be blocked, the underground water changes the flow path, and the underground water is stored in other positions. In the actual collection of underground water, there are great difficulties, so the diseases of the basement floor still exist. Therefore, the underground water collection and pumping system for the basement floor anti-floating is proposed, which comprises a collection well 100 vertically arranged below the floor 200, a first permeation pipe 300 horizontally arranged in length and spaced apart in multiple groups along the circumferential direction of the collection well 100, a second permeation pipe 400 horizontally arranged in length and spaced apart in multiple groups along the circumferential direction of the collection well 100, the second permeation pipe 400 being arranged below the first permeation pipe 300, one end of the first permeation pipe 300 and the second permeation pipe 400 being communicated with the collection well 100, a central pipe 500 vertically arranged in the collection well 100, one end of the central pipe 500 protruding from the upper end of the collection well 100 being communicated with a pump, a pushing piston 600 being arranged on the inner wall of the collection well 100, a driving mechanism driving the pushing piston 600 to reciprocate along the height direction of the collection well 100, the edge of the piston 600 being sealed with the inner wall of the collection well 100, and the piston 600 being installed on the outer wall of the central pipe 500.

[0034] In an embodiment, before the basement construction, the collection well 100 is arranged in the foundation pit, the position of the collection well 100 should be arranged in the open area above the basement without buildings, and the arrangement of the collection well 100 should be spaced according to the actual span of the open area, the spacing between the collection wells 100 should be appropriate, between 20m to 30m, and the first permeation pipe 300 and the second permeation pipe 400 are arranged in the vertical direction of the collection well 10, the first permeation pipe 300 and the second permeation pipe 400 are arranged in multiple groups along the circumferential direction of the collection well 100, the first permeation pipe 300 and the second permeation pipe 400 are selected from PVC porous hard permeation pipes, groundwater can permeate through the first permeation pipe 300 and the second permeation pipe 400, and the groundwater is guided into the collection well 100, the lower part of the collection well 100 can be selected as an open form, a part of the groundwater enters the collection well 100 through the open position of the lower part of the collection well 100, and is pumped through the central pipe 500, thereby the pumping of the water in the collection well 100 is implemented quickly, and the rapid discharge of the groundwater is ensured.

[0035] In an embodiment, a water quantity sensor can be arranged in the collection well 100, when a certain amount is reached, the pump is started to quickly implement the rapid discharge of the water flow in the collection well 100.

[0036] In an embodiment, as the service life of the material permeating water under the bottom plate increases, the groundwater permeating into the permeation pipe and the permeable stone is rich in a large amount of calcium, magnesium, iron ions, free ions and various salt acid root ions remaining in the permeable material to form salt aggregates difficult to self-dissolve, and are aggregated in the void of the permeation pipe and the various groundwater flow gaps, thereby causing the groundwater to be unable to permeate into the collection well 100, so that after 1 to 2 years of use, the problem of blockage is prone to occur, the blocking agent is introduced into the central pipe 500 by the pump, the blocking agent is filled in the collection well 100, the driving mechanism is started to drive the push piston 600 to reciprocate along the height direction of the collection well 100, thereby the blocking agent in the collection well 100 is backflowed into the first permeation pipe 300 and the second permeation pipe 400, thereby the backwashing of the first permeation pipe 300 and the second permeation pipe 400 is implemented, the blocking agent can effectively enter the first permeation pipe 300, the second permeation pipe 400 and the various groundwater flow gaps, thereby the purpose of dissolving the deposited salt is achieved, the purpose of effectively cleaning the blockage problem is achieved, the conduction of the entire groundwater flow channel is ensured, and the effective permeation of the groundwater into the collection well 100 is ensured.

[0037] In an embodiment, when the collection well 100 is filled with the blocking agent, the driving mechanism is started to drive the push piston 600 to reciprocate along the height direction of the collection well 100, so that the blocking agent is reversely flowed into the underground water fissures through the first permeation pipe 300 and the second permeation pipe 400 under the pressure, thereby realizing the dissolution of the sediment. The push piston 600 repeatedly moves up and down in the collection well 100, which can realize the repeated pumping and pushing of the blocking agent, ensure the flow of the entire blocking agent, and further ensure the dissolution of the sediment.

[0038] In an embodiment, the blocking agent is a natural polymer blocking agent, a phosphorus-containing scale inhibitor, a copolymer blocking agent, and the like, which can effectively eliminate various polymers, form soluble polymers with calcium ions, magnesium ions and the like in the permeation pipe fissures and the flow guide fissures under the floor, so that the sediment cannot be aggregated to form a large volume of sediment, and ensure the normal flow of the entire underground water and the flow into the collection well 100.

[0039] In an embodiment, the push piston 600 can be made of flexible rubber or hard high-slip stone, which can basically ensure the sealing between the push piston 600 and the collection well 100, and avoid large water leakage problems.

By starting the driving mechanism, the blocking agent in the collection well 100 can be guided out of the first permeation pipe 300 and the second permeation pipe 400 to other water flow fissures under the floor, thereby realizing the dissolution of the sediment and ensuring the conduction.

[0042] In an embodiment, when the horn sealing body 510 at the lower end of the central pipe 500 is separated from the annular table 130 at the lower end of the collection well 100, this state is the normal state of water flow pumping in the collection well 100. By starting the pump, the water flow in the collection well 100 is pumped in real time through the central pipe 500 to reduce the buoyancy received by the basement floor.

[0043] In an embodiment, to ensure the permeated water flow from the lower end of the collection well 100 into the collection well 100, the lower end of the collection well 100 is integrally open, and the lower end of the collection well 100 is spaced in a circumferential direction by a water collection channel 110, which is arranged along the radial direction of the collection well 100, and the lower end of the collection well 100 is further extended to be provided with an anti-floating flap 120.
