Description

Technical Field

[0001] The invention relates to the technical field of anti-floating foundation treatment, and in particular to a groundwater collection and drainage system for anti-floating of basement bottom plates. Background Art

[0002] Anti-floating design is an important part of basement design. In actual projects, the current measures to solve anti-floating mainly include precipitation method, weight method, setting up anti-pullout piles or anti-floating anchors, etc. Different anti-floating methods have their own advantages, disadvantages and applicability. Although relevant building codes have also conducted relevant explorations, the relevant regulations are not clear enough, there is a lack of unified understanding of anti-floating design, the current anti-floating design concept is incomplete, and a clear system theory has not been established. In addition, the commonly used anti-floating design models and calculation methods are also simplified. When the groundwater level rises during rain, the basement bottom slab is gradually subjected to upward pressure until the pressure exceeds the limit of the slab, and the basement bottom slab bulges and cracks.

[0003] In order to solve the above-mentioned problems caused by the floating of the basement, the weight method, anti-pulling pile or anti-floating anchor rod method are often used. However, the above-mentioned construction is very costly and the construction period is very long. In order to solve the above-mentioned problems of high cost and low construction efficiency, there is also a method in the prior art of setting a pressure relief well on the basement floor to pump out the groundwater to reduce the floating problem caused by the groundwater under the basement floor. Although the above-mentioned method of pumping out the pressure relief well can relieve pressure and effectively reduce the construction cost, when the above-mentioned drainage is carried out by the pumping method, the infiltration pipe under the basement floor will be blocked as the use time increases. The blockage of the infiltration pipe is mostly caused by the deposition of silt or other sediment solids. The pressure relief well cannot fully collect the water flow below the basement substrate, so it will still cause the basement floor to be damaged. Summary of the invention

[0031] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described in conjunction with the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present 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 combined with Figures 1 to 10 , the water collection system under the basement floor of the present invention is described in detail:

[0033] The basement floor is susceptible to certain damage caused by the rise of groundwater, such as cracking and arching of the basement floor. What's worse, the basement's load-bearing columns may crack or break. Therefore, the anti-floating design of the basement is the focus of actual construction. The reason for the buoyancy of the basement floor is mostly due to the infiltration of rainwater from the outside. The precipitation from the outside infiltrates through the outer side walls of the building and penetrates under the side walls of the building into the basement floor. There is also a part of groundwater flowing in from under the basement floor. As the groundwater accumulates, the groundwater creates buoyancy on the building's floor, which can easily cause the above-mentioned damage. The larger the span of the basement, the more obvious the above-mentioned damage. The larger the span of the basement, the more obvious the gravity of the building above the basement can resist the buoyancy under the basement floor. However, the larger the span of the open area between the buildings, the greater the buoyancy of the basement floor under the open area. The shear force is generated on the basement floor, which can easily cause the damage caused by the buoyancy of the basement. In the prior art, pull-out piles or anti-floating anchors are often used to eliminate the buoyancy generated by the basement floor, which requires dense arrangement of pull-out piles or anti-pull-out anchors. However, the actual construction cost is very high, and a lot of basic construction work needs to be done before the basement construction, resulting in low construction efficiency. Therefore, a method of collecting and pumping groundwater to eliminate the buoyancy under the basement floor is currently proposed. However, when collecting groundwater, porous stones are often used for filling, and infiltration pipes are buried in the stones. However, as time goes by, The growth of the limit will easily cause blockage in the infiltration pipe and the stone, and the groundwater will change its flow path. The groundwater will remain in other places of the groundwater. When actually collecting the groundwater, there will be great difficulties. Therefore, it will still cause the problem of basement floor disease. In this regard, the present invention proposes a groundwater collection and drainage system for anti-floating basement floor, including a collection well 100, which is vertically arranged at a position below the bottom plate 200; a first infiltration pipe 300, which is horizontal in length and is arranged in multiple groups along the circumferential direction of the collection well 100; a second infiltration pipe 400, which is horizontal in length and is arranged in multiple groups along the circumferential direction of the collection well 100. The second permeation tube 400 is arranged below the first permeation tube 300; one end of the first permeation tube 300 and the second permeation tube 400 are connected to the collection well 100; a central tube 500 is vertically arranged in the collection well 100, and one end of the central tube 500 extends out of the upper end of the collection well 100 and is connected to a pump; a push piston 600 is arranged on the inner wall of the collection well 100, and a driving mechanism drives the push piston 600 to reciprocate along the height direction of the collection well 100, and the edge of the piston 600 is sealed with the inner wall of the collection well 100, and the piston 600 is installed on the outer wall of the central tube 500.

[0034] In one embodiment, before the basement is built, a collection well 100 is set in the foundation pit. The collection well 100 should be arranged in an open area above the basement where there is no building, and the collection wells 100 should be arranged at intervals according to the actual span of the open area. The spacing between the collection wells 100 should be appropriate, between 20m and 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 along the collection well. A plurality of groups of groundwater are arranged at intervals in the circumferential direction of 100. The first permeation tube 300 and the second permeation tube 400 are made of PVC porous hard permeation tubes. Groundwater can pass through the first permeation tube 300 and the second permeation tube 400 to be introduced into the collection well 100. The bottom of the collection well 100 can be open. A portion of the groundwater enters the collection well 100 through the open position below the collection well 100, and the central tube 500 is pumped by a pump, thereby pumping the water in the collection well 100 to ensure the rapid discharge of groundwater.

[0035] In one embodiment, a water volume sensor may be provided in the collection well 100. When a certain volume is reached, the water in the collection well 100 may be quickly drained out by starting a pump.

[0036] In one embodiment, as the service life of the infiltrating water material under the bottom plate increases, the groundwater infiltrating into the permeable gravel and the permeable pipe is rich in a large amount of calcium, magnesium, iron and other ions. The free ions and various hydrochloric acid ions remaining in the permeable material form salt aggregates that are difficult to dissolve by themselves, and accumulate in the gaps in the permeable pipe and various groundwater diversion gaps, thereby preventing the groundwater from infiltrating into the collection well 100. After 1 to 2 years of use, the problem of clogging is likely to occur. A blocking agent can be introduced into the central pipe 500 by a pump, so that after the collection well 100 is filled with the blocking agent, by starting The driving mechanism drives the pushing piston 600 to move back and forth along the height direction of the collection well 100, so that the blocking agent in the collection well 100 flows back into the first permeation tube 300 and the second permeation tube 400, thereby implementing backwashing of the first permeation tube 300 and the second permeation tube 400, so that the blocking agent can effectively enter the first permeation tube 300, the second permeation tube 400 and each groundwater diversion gap, thereby achieving the purpose of ablating the deposited salt, achieving the purpose of effectively clearing the blockage problem, ensuring the conduction of the entire groundwater diversion channel, and ensuring that the groundwater can effectively penetrate into the collection well 100.

[0037] In one embodiment, when the collection well 100 is filled with the blocking agent, the driving mechanism is started to drive the piston 600 to move back and forth along the height direction of the collection well 100, and then under the action of pressure, the blocking agent flows back to each groundwater gap through the first permeation tube 300 and the second permeation tube 400, thereby achieving the ablation of the sediment. The piston 600 is pushed up and down repeatedly in the collection well 100, which can achieve repeated suction and push out of the blocking agent, thereby ensuring the flow of the entire blocking agent and thus ensuring the ablation of the sediment.

[0038] In one embodiment, the blocker is a natural polymer blocker, a phosphorus-containing descaling agent, a copolymer blocker and other varieties, which can effectively eliminate various polymers and form soluble polymers with calcium ions, magnesium ions and the like in the permeation pipe gaps and diversion gaps under the bottom plate, so that the precipitates cannot aggregate to form a larger volume of precipitates, thereby ensuring the normal diversion of the entire groundwater and diverting it to the collection well 100.

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

[0040] In one embodiment, a trumpet seal 510 is provided at the lower end of the central tube 500, and an annular table 130 is provided on the inner wall of the lower end of the collecting well 100. The large-sized end of the trumpet seal 510 and the annular table 130 constitute two states. One is that the large-sized end of the trumpet seal 510 abuts against the annular table 130, and the lower end of the collecting well 100 is sealed, corresponding to the driving mechanism driving the piston 600 to reciprocate along the inner wall of the collecting well 100. The other is that the large-sized end of the trumpet seal 510 is separated from the annular table 130, corresponding to the start of the pump.

[0041] In one embodiment, when the trumpet seal 510 at the lower end of the central tube 500 abuts against the annular table 130 at the lower end of the collecting well 100, the piston 600 is pushed to form a closed space in the collecting well 100. By starting the driving mechanism, the blocking agent in the collecting well 100 can be guided from the first permeation tube 300 and the second permeation tube 400 to other water flow gaps under the bottom plate, thereby dissolving the precipitate and ensuring conduction.

[0042] In one embodiment, when the trumpet seal 510 at the lower end of the central pipe 500 is separated from the annular table 130 at the lower end of the collecting well 100, this state is the normal state of water suction in the collecting well 100. By starting the pump, the water in the collecting well 100 is suctioned in real time through the central pipe 500 to reduce the buoyancy of the basement floor.

[0043] In one embodiment, in order to ensure that the infiltrated water flows into the collection well 100 from the lower end of the collection well 100, the lower end of the collection well 100 is open as a whole, and the lower end of the collection well 100 is provided with water collection channels 110 at intervals in the circumferential direction. The water collection channels 110 are arranged along the radial direction of the collection well 100, and the lower end of the collection well 100 is also extended with an anti-floating plate 120.

[0044] In one embodiment, external water flows into the collection well 100 through the first permeation tube 300 and the second permeation tube 400, and a portion of water flows into the interior from the lower end opening of the collection well 100 through the water collection channel 110, thereby collecting groundwater in real time.

[0045] In one embodiment, the collection well 100 and the anti-floating plate 120 form a "T"-shaped cap structure. The anti-floating plate 120 is placed on the base surface of the foundation pit, which can effectively improve the stability of the entire collection well 100 and support the bottom plate of the bottom line chamber.

[0046] In one embodiment, arranging the first permeable pipe 300 and the second permeable pipe 400 in the vertical direction of the collection well 100 can ensure effective collection in the vertical space of the basement, and the arrangement spacing of the first permeable pipe 300 and the second permeable pipe 400 should not be too large.

[0047] In one embodiment, a branch pipe 310 is provided on the body of the first permeation tube 300, and an extended end of the branch pipe 310 is connected to the collection well 100. An extrusion piston 320 is provided in the tube cavity at one end of the first permeation tube 300. The extrusion piston 320 slides back and forth along the tube cavity of the first permeation tube 300 and pushes the liquid in the first permeation tube 300.

[0048] In one embodiment, for collecting groundwater at an upper position, a branch pipe 310 is provided on the first permeation tube 300, and the branch pipe 110 is located below the first permeation tube 300. By starting the driving mechanism, the piston 600 is pushed to move back and forth along the collection well 100, and the extrusion piston 320 can also be linked to drive the first permeation tube 300 to push the blocking agent in the first permeation tube 300, thereby ensuring that the blocking agent in the first permeation tube 300 can flow repeatedly, ensuring that the blocking agent can dissolve the sediment in the gap, and ensuring that the first permeation tube 300 can effectively collect the infiltration of groundwater.

A wedge-shaped folding plate 322 is provided at one end of the extrusion piston 320, and the outer side of the wedge-shaped folding plate 322 abuts against the driving roller 323. The driving mechanism drives the piston 600 to reciprocate along the inner wall of the collection well 100 and links the extrusion piston 320 to slide back and forth along the tube cavity of the first permeation tube 300.

[0050] In one embodiment, the above-mentioned driving mechanism drives the push piston 600 to move back and forth along the inner wall of the collection well 100, so that the push piston 600 moves back and forth along the inner wall of the collection well 100, and links the flow of the entire blocking agent in the entire collection system, and can also link the extrusion piston 320 to slide back and forth along the tube cavity of the first permeation tube 300, thereby driving the blocking agent in the first permeation tube 300 at a high position, so that the blocking agent can flow back and forth in the first permeation tube 300 and the gap, ensuring the water flow in the gap of the entire collection system is conductive.

[0051] Furthermore, in order to support the pushing piston 600 so that the pushing piston 600 is in a high position under normal conditions, a support body 700 is provided at the upper end of the collecting well 100. The support body 700 is annular as a whole and a rubber elastic body 710 is provided between the upper end of the collecting well 100. The rubber elastic body 710 is coaxially arranged with the support body 700. A drive cover 720 is coaxially arranged above the support body 700. A plurality of groups of reset elastic bodies 730 are arranged at intervals in the circumferential direction between the drive cover 720 and the annular surface of the support body 700. The reset elastic bodies 730 are arranged along the axial direction of the support body 700, and the wheel frame of the drive roller 323 is installed on the drive cover 720.

[0052] In one embodiment, the rubber elastic body 710 can support the support body 700 so that the support body 700 is in a normal state under normal conditions, thereby linking the internal pushing piston 600 and the center tube 500 to a high position, so that the horn seal body 510 at the lower end of the center tube 500 is separated from the annular table 130 at the lower end of the collection well 100, so that under normal conditions, the groundwater in the collection well 100 can be pumped out to ensure that the groundwater below the basement floor is in a reasonable state.

[0053] In one embodiment, the driving mechanism further comprises a driving ring 520 disposed on the outer wall of the central tube 500 , the driving ring 520 abuts against the upper cover surface of the driving cover 720 , and the upper end of the central tube 500 is connected to the pump via a hose 530 .

[0054] In one embodiment, a working well 210 is provided on the upper surface of the base plate 200, and a manhole cover 220 is vertically slidably provided at the wellhead position of the working well 210, a driving pipe 221 is extended on the manhole cover 220, the center pipe 500 passes through the driving pipe 221 to communicate with the outside, the driving pipe 221 abuts against the upper ring surface of the driving ring 520, and the driving mechanism also includes a driving eccentric body 540 arranged above the cover surface of the manhole cover 220, one end of the driving eccentric body 540 is provided with a driving wheel 541, the driving wheel 541 abuts against or moves away from the upper surface of the manhole cover 220, and the other end of the driving eccentric body 540 is rotatably mounted on the frame through a rotating shaft, and a driving motor 542 drives the rotating shaft to rotate.

[0055] When the backwashing operation is implemented in the entire collection system, the driving eccentric body 540 is driven by starting the driving motor 542, and then the manhole cover 220 is driven to slide up and down along the working well 210, so that the driving ring 520 is driven in real time through the driving tube 221 to drive the support body 700 through the central tube 500, so as to compress the rubber elastic body 710, and then the pushing piston 600 is pushed back and forth to suck and push out the blocking agent, so that the blocking agent flows back and forth in the gaps of the entire groundwater collection system to ensure the ablation of sediments and conduction. At this time, the trumpet sealing body 510 at the lower end of the central tube 500 abuts against the annular table 130 at the lower end of the collection well 100, so that the collection well 100 presents a closed space.

[0056] In one embodiment, in order to adjust the position state of the central tube 500 so that the trumpet seal 510 at the lower end of the central tube 500 abuts against or separates from the annular table 130 at the lower end of the collection well 100, thereby ensuring that the central tube 500 switches between the two states of pumping groundwater or introducing blocking agents, a limiting wheel 550 is rotatably provided on the manhole cover 220, and the limiting wheel 550 abuts against or moves away from the upper plate surface of the manhole cover 220, and the limiting wheel 550 is assembled to be able to adjust the height of the upper cover surface of the manhole cover 220.
