A basement floor anti-buoyancy system and method

Abstract

This invention relates to an anti-buoyancy system and method for basement floor slabs, comprising a water collection chamber located below and to the side of a side wall; multiple capillary water collection pipes spaced apart along the depth and length of the trench in the side wall; a collection pipe extending from the bottom of the side wall to the bottom of the water collection chamber and communicating with the inner cavity of the water collection chamber; and a suction pipe connected to a pump, which drives the suction pipe to suction the water flow in the water collection chamber. During the anti-buoyancy operation of the basement floor slab, multiple sets of capillary water collection pipes are spaced apart along the length and height of the trench and connected to the collection pipe. Water can be directed through the capillary water collection pipes to the collection pipe, which then leads into the water collection chamber. By starting the pump, the suction pipe rapidly suctions the water flow below the water collection chamber, effectively reducing the groundwater level in the trench and thus effectively preventing buoyancy in the basement floor slab, thereby reducing damage caused by buoyancy issues.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of anti-floating foundation treatment, in particular to a basement bottom plate anti-floating system and anti-floating method. BACKGROUND

[0002] The basement bottom plate is prone to be affected by the underground water floating and cause certain diseases, such as basement bottom plate cracking, arching, and even more serious cracking or breaking of the basement bearing column, so the anti-floating design of the basement is the focus of the actual construction. The reason for the basement bottom plate to produce the floating force is that the external rainwater seeps in through the fat groove position of the building peripheral side wall and seeps into the basement bottom plate below through the building side wall below. With the accumulation of underground water, the underground water produces a floating force on the bottom plate of the building, thus easily causing the above-mentioned diseases, and the larger the span of the basement, the more obvious the above-mentioned diseases. The larger the span of the basement, the greater the gravity of the building above the basement can resist the floating force below the basement bottom plate. However, the larger the span of the empty area between buildings, the greater the shear force on the basement bottom plate below the empty area, which can easily cause the diseases caused by the floating force of the basement. In the prior art, the anti-floating pile or anti-floating anchor rod is used to eliminate the floating force of the basement bottom plate, and the anti-floating pile or anti-floating anchor rod needs to be densely arranged. However, the actual construction cost is high, and a large amount of foundation construction work needs to be done before the construction of the basement, which leads to low construction efficiency.

[0036] In order to make the objects and advantages of the present application more clear, the following will make a specific description of the present application in combination with embodiments. It should be understood that the following description is only used to describe one or several specific embodiments of the present application, and does not strictly limit the scope of protection of the present application. As used herein, the terms "parallel" and "perpendicular" are not limited to their strict geometric definitions, but include reasonable and inconsistent tolerances for machining or human error;

[0037] The present application will be described in greater detail below in combination with the accompanying drawings Figures 1 to 13 The basement floor anti-floating system of the present application will be described in detail:

[0038] The basement floor is prone to certain diseases caused by the upward floating of underground water, such as cracking and arching of the basement floor, and even more seriously, cracking or breaking of the load-bearing column of the basement. Therefore, the anti-floating design of the basement is the focus of actual construction. The reason for the floating of the basement floor is mainly the infiltration of external rainwater. The external precipitation infiltrates through the fat groove of the peripheral side wall of the building and infiltrates under the side wall of the building to the bottom of the basement floor. There is also a part of the underground water flowing into the bottom of the basement floor. With the accumulation of underground water, the underground water generates a floating force on the floor of the building, thus easily causing the above-mentioned diseases. Moreover, the larger the span of the basement, the more obvious the above-mentioned diseases. The larger the span of the basement, the greater the gravity of the building above the basement can resist the floating force under the basement floor. However, the larger the span of the empty area between buildings, the greater the shear force on the basement floor under the empty area, thus easily causing the diseases caused by the floating force of the basement.

[0039] To this end, the present application provides a basement floor anti-floating system and an anti-floating method. The basement floor anti-floating system comprises a water collecting chamber 100 arranged below the side wall 200; a plurality of capillary water collecting pipes 300 are arranged in the fat groove of the side wall 200 in the length direction; a collecting pipe 400 extends from the bottom of the side wall 200 to the bottom of the water collecting chamber 100 and communicates with the inner chamber of the water collecting chamber 100; a suction pipe 500 communicates with a pump, and the pump drives the suction pipe 500 to suck the water flow in the water collecting chamber 100.

[0040] In an embodiment, the capillary water collecting pipe 300 is a permeable pipe commonly used in the engineering field, and a large number of voids exist on the capillary water collecting pipe 300. When the capillary water collecting pipe 300 is arranged in multiple groups along the width direction and the depth direction of the fertilizer groove, the water flow in the fertilizer groove can effectively permeate through the capillary water collecting pipe 300 into the collecting pipe 400, and then be guided into the bottom of the water collecting chamber 100 through the collecting pipe 400. The suction pipe 500 is arranged in the water collecting chamber 100, and when the pump is started, the suction pipe 500 can be pumped, so that the water flow in the side wall fertilizer groove can be effectively reduced to enter the bottom plate of the basement, thereby effectively reducing the buoyancy generated by the basement bottom plate to reduce the occurrence of basement bottom plate diseases.

[0041] In an embodiment, the water collecting chamber 100 is provided with a casing 600, the lower end of the casing 600 is provided with a filter disc 610, the lower side of the filter disc 610 is provided with an isolation disc 620, the filter disc 610 and the isolation disc 620 are arranged in a spaced manner, the isolation disc 620 is arrayed with filter holes, and the lower end of the water collecting chamber 100 is arranged on the upper disc surface of the filter disc 610.

[0042] In an embodiment, the casing 600 is a prefabricated concrete cylinder structure, and the water collecting chamber 100 is installed in the casing 600. When the water flow in the fertilizer groove enters the filter disc 610 through the isolation disc 620, it can further enter the water collecting chamber 100, thereby improving the collection effect of the water collecting chamber 100 on underground water.

[0043] In an embodiment, by arranging the isolation disc 620 and the filter disc 610 at the lower end of the water collecting chamber 100, large stones can be effectively blocked from entering the water collecting chamber 100, so that underground water can seep into the water collecting chamber 100, thereby implementing pumping of underground water.

[0044] In an embodiment, in order to collect underground water below the basement bottom plate, the lower end of the water collecting chamber 100 is provided with a water collecting chamber 110, the lower end surface of the water collecting chamber 100 is provided with a water guide groove 120, the water guide groove 120 is arranged along the radial direction of the water collecting chamber 100, multiple groups of the water guide groove 120 are arranged along the circumferential direction of the water collecting chamber 100, both ends of the water guide groove 120 are respectively communicated with the filter disc 610 and the water collecting chamber 110, and one end of the collecting pipe 400 extends into the water collecting chamber 110.

[0045] In an embodiment, the groundwater is collected on the filter disc 610, the water flows into the water collecting chamber 110 through the water guide groove 120, and the collecting pipe 400 is a PVC pipe, the collecting pipe 400 also communicates with the water collecting chamber 110, and the water collecting chamber 110 can effectively collect the groundwater, the lower end of the suction pipe 500 extends into the water collecting chamber 110, and the water in the water collecting chamber 110 can be effectively pumped by starting the pump to reduce the groundwater pressure under the basement floor and reduce the buoyancy of the basement floor.

[0046] In an embodiment, the water collecting bin 100 is also provided with a transition chamber 130, which is arranged above and communicates with the water collecting chamber 110, and a first table surface 131 is arranged between the transition chamber 130 and the water collecting chamber 110, the lower end of the suction pipe 500 is provided with a water baffle 510, the water baffle 510 slides in the transition chamber 130, and when the water baffle 510 abuts against the first table surface 131, the pump is started and the water in the water collecting chamber 110 is pumped.

[0047] In an embodiment, the water baffle 510 is made of flexible rubber material, and the water baffle 510 as a whole has a horn-shaped arrangement that is small at the top and large at the bottom, and when the water baffle 510 abuts against the first table surface 131 in the transition chamber 130, the water collecting chamber 110 and the transition chamber 130 are isolated, the pump is started, and the suction pipe 500 can pump the water in the water collecting chamber 110 alone to reduce the water buoyancy under the basement floor in a short time.

[0048] In an embodiment, during actual groundwater collection, multiple gap stones are often used for filling, and a permeable pipe is buried in the stones, but as the use time increases, the capillary tube and the permeable pipe and the stones arranged under the basement are easily blocked, the groundwater changes the flow path, and the groundwater remains in other positions of the groundwater, so there are great difficulties in actual groundwater collection, and therefore the basement floor disease problem still exists.

[0049] To this end, the water collecting chamber 100 is further provided with a compression chamber 140, which is arranged above the transition chamber 130 and is in communication. The compression chamber 140 is provided with a compression piston 700, and the outer wall of the compression piston 700 abuts against the inner wall of the compression chamber 140.

The entire pipeline can be cleaned by lifting the suction pipe 500, so that the water baffle 510 abuts against the second table surface 132, so that the compression chamber 140 forms a closed space. By introducing cleaning water into the compression chamber 140, the driving mechanism is started, so that the cleaning water is pushed into the collecting pipe 400 from the cleaning water pipe 150, and then introduced into the capillary water collecting pipe 300 through the collecting pipe 400. The clogging in the gap of the capillary water collecting pipe 300 is backwashed to ensure that the entire water collecting system can efficiently collect underground water.

[0051] In an embodiment, the cleaning water can add a certain blocking agent, which can effectively eliminate the deposits in the capillary water collecting pipe 300, improve the backwashing effect, and the addition of the cleaning agent in the compression chamber 140 can separately arrange a cleaning water adding system to introduce the cleaning water into the compression chamber 140.
