Description

Technical Field

[0001] This application relates to the field of drainage, and in particular to a drainage system and construction method for a deep foundation pit basement. Background Technology

[0002] Waterproofing of basements in deep foundation pit construction mainly relies on the structure's self-waterproofing and the application of waterproofing materials constructed according to specifications. However, leakage is unavoidable in deep foundation pit construction due to factors such as the quality of waterproofing materials (rolls, waterproof concrete, etc.), workmanship, material characteristics, and inadequate quality behavior and awareness among subcontractors and management personnel. Therefore, a drainage system is necessary for the basement of deep foundation pits.

[0003] Among related technologies, Chinese patent CN114439038A discloses a drainage system for a deep foundation pit basement, including a foundation slab, a structural floor slab, and semi-circular PVC pipes embedded along the corners of the foundation slab and the structural floor slab from the exterior wall. The semi-circular PVC pipes of the upper and lower layers are connected by vertical PVC pipes. A horizontal drainage board is laid on the foundation slab. Concrete flooring is poured on the horizontal drainage board and the structural floor slab in areas other than where the PVC pipes are laid. Cement mortar is laid on the semi-circular PVC pipes embedded in the structural floor slab. Vertical drainage boards and cement pressure boards are fixed at the drainage points on the exterior wall, and other areas are coated with a plaster layer.

[0004] When water seeps through the interior trim panels, it flows into the semi-circular PVC pipe at the inside corner where the structural floor slab and the interior trim panels meet, and then flows along the vertical PVC pipe into the semi-circular PVC pipe on the foundation slab. The water travels a long path in the vertical PVC pipe, and after long-term use, impurities easily accumulate in the vertical PVC pipe, clogging it and affecting drainage. Therefore, this needs to be improved. Summary of the Invention

[0005] To address the issue of vertical PVC pipes being prone to clogging and affecting drainage, this application provides a drainage system and construction method for deep foundation pit basements.

[0006] Firstly, the drainage system for deep foundation pit basements provided in this application adopts the following technical solution:

[0007] A drainage system for deep foundation pit basements, used to drain seepage water at the junctions of walls and foundation slabs, and at the junctions of walls and structural floor slabs, comprising:

[0008] The upper cover pipe is horizontally installed and fixedly connected to the structural floor slab. The upper cover pipe is located at the edge of the structural floor slab and is used to cover the connection between the wall and the structural floor slab.

[0009] A lower cover pipe is horizontally arranged and fixedly connected with the foundation bottom plate, and is arranged at the edge of the foundation bottom plate to cover the joint of the wall body and the foundation bottom plate.

[0010] A connecting pipe is vertically arranged between the upper cover pipe and the lower cover pipe to connect the upper cover pipe and the lower cover pipe, and an open-top storage tank is fixed on the inner wall of the connecting pipe to store impurities in water.

[0011] A guide assembly is arranged in the connecting pipe to divide the connecting pipe into an upper sewage area and a lower clean water area, and the guide assembly is used to guide all water in the sewage area into the storage tank.

[0012] When the wall body leaks, water flows along the wall body to the joint of the wall body and the structural floor, i.e. the upper cover pipe, and then flows into the connecting pipe. When the water flows to the guide assembly, the guide assembly guides the water into the storage tank. When the water in the storage tank accumulates at the opening of the storage tank, the water overflows from the opening of the storage tank, part of the water passes through the filter plate into the clean water area, and the filter plate filters the water so that only water can flow through the filter plate and the impurities in the water are left in the storage tank. Another part of the water re-enters the sewage area and then is guided by the guide assembly into the storage tank, and then enters the clean water area through the filter plate.

[0013] The guide assembly simultaneously blocks the water in the sewage area, so that the water in the sewage area must pass through the storage tank to reach the clean water area, and the water in the storage tank must pass through the filter plate to enter the clean water area, so that the impurities are stored in the storage tank, thereby preventing the impurities from being stored between the storage tank and the inner wall of the connecting pipe in the clean water area, and preventing the connecting pipe from being blocked by the impurities.

[0014] Optionally, a plurality of filter holes are arranged through the side wall of the storage tank, and the diameter of the filter holes is smaller than the diameter of the impurities in the water.

[0015] By using the above technical solution, when the guide assembly guides the water in the sewage area into the storage tank, the water in the storage tank directly passes through the filter holes into the clean water area, and the impurities in the water cannot pass through the filter holes, so that the impurities are left in the storage tank, the rate of draining the relatively clean water to the clean water area is increased, and the efficiency of draining water is improved.

[0016] Optionally, the guide assembly comprises:

[0017] A driving wheel is arranged in the connecting pipe and rotationally connected to the inner wall of the connecting pipe.

[0018] A driven wheel is arranged in the connecting pipe and rotationally connected to the inner wall of the connecting pipe. The driven wheel is located on the side of the central axis of the connecting pipe away from the driving wheel, below the driving wheel, and at the opening of the storage box.

[0019] A conveying belt is sleeved on the driving wheel and the driven wheel. The driving wheel is rotated to drive the conveying belt to move. The sewage area is located above the conveying belt, the clean water area is located below the conveying belt, and the filter plate is below the conveying belt.

[0020] A rotating rod is horizontally arranged in the connecting pipe. One end of the rotating rod extends out of the connecting pipe, and the rotating rod is coaxially fixed with the driving wheel.

[0021] When water moves downward along the connecting pipe to the direction of the cover pipe, the water first falls on the conveying belt, so that part of the impurities in the water are left on the conveying belt. Then the rotating rod is driven to rotate, so that the driving wheel rotates to drive the conveying belt to move, so that the conveying belt drives the impurities left on the conveying belt to move in the direction of the storage box, and then falls from the edge of the conveying belt into the storage box, so that the impurities are not accumulated on the conveying belt, reducing the possibility of the connecting pipe being blocked by the impurities accumulated between the conveying belt and the inner wall of the connecting pipe, so as to not affect the drainage.

[0022] Optionally, a plurality of flow-through holes are arranged through the conveying belt. The diameter of the flow-through holes is smaller than the diameter of the impurities in the water.

[0023] By adopting the above technical scheme, when the water falls on the conveying belt, the water directly enters the clean water area through the flow-through holes, and the impurities in the water cannot pass through the flow-through holes, so as to be left on the upper surface of the conveying belt. The rate of relatively clean water being discharged to the clean water area is increased, and the efficiency of drainage is improved.

[0024] Optionally, a plurality of push rods are fixed on the conveying belt. The end of the push rod away from the conveying belt can abut against the inner wall of the connecting pipe. The distance between the plurality of push rods is smaller than the diameter of the impurities in the water.

[0025] By adopting the technical scheme, water enters the storage tank from the top opening of the storage tank, and the moving of the conveying belt also sends impurities to the opening of the storage tank, so that the impurities in the water and the impurities on the conveying belt are all gathered at the bottom end of the conveying belt, thereby impurities are easily accumulated between the bottom end of the conveying belt and the inner wall of the connecting pipe, and the conveying belt also drives the plurality of poking rods to move in the moving process, when the poking rod moves to the bottom end of the conveying belt, the impurities accumulated through the bottom of the conveying belt, thereby the accumulated impurities are stirred and dispersed, and part of the impurities are pushed into the storage tank, so that the accumulated impurities are loose and easy to fall into the storage tank, thereby the opening of the storage tank is not easy to be blocked, and the drainage is not affected.

[0026] Optionally, a plurality of cleaning rods are fixed on the side wall of the conveying belt close to the filter plate, the cleaning rods are staggered with the poking rods, one end of the cleaning rod away from the filter plate abuts against the side wall of the conveying belt, and the poking rod can pass through between adjacent cleaning rods.

[0027] By adopting the technical scheme, when the poking rod moves to the bottom of the conveying belt, the poking rod moves to the bottom of the conveying belt with the center axis of the driven wheel as the axis, in this process, each poking rod passes through between adjacent cleaning rods, so that the impurities embedded between adjacent poking rods are scraped down by the cleaning rods, thereby the cleaning rods play a cleaning role on the poking rods, and the poking rods do not carry impurities to the bottom of the conveying belt and fall into the clean water area, thereby the clean water area in the connecting pipe is not easy to be blocked by impurities, and the drainage is not affected.

[0028] Optionally, the connecting pipe comprises:

[0029] The mounting pipe is vertically arranged, a sleeve is vertically inserted into the structural floor, the top end of the sleeve is communicated with the upper cover pipe, the top end of the mounting pipe is inserted into the sleeve, and the storage tank and the guide assembly are arranged in the mounting pipe;

[0030] The fixing pipe is vertically arranged below the mounting pipe, the bottom end of the fixing pipe is fixed and communicated with the lower cover pipe, the fixing pipe is provided with a connecting assembly, and the connecting assembly is used for connecting the top of the fixing sleeve and the bottom of the mounting pipe;

[0031] The hose is inserted into the bottom of the mounting pipe at one end, and the outer wall of the hose is fixedly attached to the inner wall of the mounting pipe, and the other end of the hose is inserted into the fixing pipe.

[0032] By adopting the technical scheme, when too many impurities are accumulated in the storage box, the connecting assembly is separated from the mounting pipe, so that the mounting pipe can move up and down, then the mounting pipe is manually moved downward until the mounting pipe is separated from the sleeve, then the mounting pipe is translated in the horizontal direction, so that the hose is deformed and directly separated from the fixed pipe. Then the new mounting pipe is in the vertical direction and is moved to the position directly below the sleeve, then the mounting pipe is moved upward, so that the top end of the new mounting pipe is inserted into the sleeve, then the hose is deformed and is convenient to be inserted into the fixed pipe, the connecting assembly is used to fixedly connect the mounting pipe and the fixed pipe, so that the replacement of the mounting pipe is realized, the problem that too many impurities are accumulated in the sewage area when too many impurities are accumulated in the storage box is solved, and the influence on drainage is avoided.

[0033] Optionally, the mounting pipe is sleeved with a sealing sleeve, the sealing sleeve is fixedly connected with the mounting sleeve and is located at the top of the mounting sleeve, and the outer wall of the sealing sleeve abuts against the inner wall of the sleeve.

[0034] By adopting the technical scheme, when installing, the mounting pipe drives the sealing sleeve to be directly inserted into the sleeve, the sealing sleeve is deformed, that is, the interference fit between the mounting pipe and the sleeve is formed, so that the extrusion force is always applied to the inner wall of the sleeve, the sealing sleeve is tightly attached to the inner wall of the sleeve, the sealing effect is achieved, and water cannot be directly discharged from the sleeve.

[0035] Optionally, the connecting assembly comprises:

[0036] The connecting ring is fixedly sleeved on the fixed pipe and is located at the top of the fixed pipe.

[0037] The connecting block is inserted into the connecting hole in the inner wall of the connecting ring and can move in the connecting hole, the connecting block is connected with the inner wall of the connecting hole through the connecting spring, the connecting spring is used to push the connecting block towards the direction close to the central axis of the connecting ring, the side wall of the mounting pipe is provided with a mounting hole for inserting the connecting block, the connecting block is fixedly connected with a connecting rod, and one end of the connecting rod extends out of the connecting sleeve.

[0038] By adopting the technical scheme, when the top end of the installation pipe is inserted into the sleeve and the bottom hose is also inserted into the fixed pipe, then the connecting rod is manually pulled, the connecting block compresses the connecting spring and is accommodated in the connecting hole, the position of the installation pipe is adjusted up and down, the installation hole is aligned with the connecting block, the force of pulling the connecting rod is released, the connecting spring restores the deformation, the connecting block is pushed towards the installation pipe, until the connecting block is inserted into the installation hole, the side wall of the connecting block abuts against the inner wall of the installation hole, the supporting is limited, the installation pipe is fixedly connected with the connecting ring, and the installation of the installation pipe is realized. When the middle water of the upper cover pipe flows into the sleeve, enters the installation pipe, and enters the hose along the installation pipe, because the hose is directly inserted into the fixed pipe, the water in the hose directly enters the fixed pipe, and no leakage occurs, and then the water enters the lower cover pipe from the fixed pipe and is discharged.

[0039] In a second aspect, the construction method of the deep foundation pit basement drainage system provided by the application adopts the following technical scheme:

[0040] S1, the foundation slab and the wall are waterproofed by using self-adhesive waterproof coiled material, the leakage points of the foundation slab and the wall are concentrated at the connection of the foundation slab and the wall, and the drainage position is determined;

[0041] S2, a lower cover pipe for covering the connection is buried at the connection of the foundation slab and the wall, then a horizontal drainage plate is laid on the surface of the foundation slab, the horizontal drainage plate covers the lower cover pipe, and an upper cover pipe for covering the connection is buried at the connection of the structural floor and the wall;

[0042] S3, the floor concrete is poured on the foundation slab, but the area of the foundation slab occupied by the lower cover pipe is temporarily not poured with the floor concrete, the floor concrete is also poured on the structural floor, but the area of the structural floor occupied by the upper cover pipe is not poured with the floor concrete, and the cement mortar is poured on the upper cover pipe, so that the upper cover pipe is fixed on the structural floor and is also protected;

[0043] S4, a plurality of sleeves are pre-buried on the structural floor along the arrangement direction of the upper cover pipe, then an installation pipe is inserted into the sleeve, the sealing sleeve on the outer wall of the installation pipe abuts against the inner wall of the sleeve, sealing is realized, a hose at the bottom of the installation pipe is inserted into a fixed pipe, and the bottom of the fixed pipe is fixed with the lower cover pipe through a connecting ring and communicates with the lower cover pipe;

[0044] S5, a vertical drainage plate is arranged at the drainage position, the vertical drainage plate is fixed on the wall, the wall between adjacent vertical drainage plates is painted, and then a cement pressure plate is fixed on the surface of the vertical drainage plate for fixation;

[0045] S6. After observing that there is no leakage and the drainage is smooth on the outside of the wall, fill in the gaps in the foundation slab and structural floor slab where the floor concrete has not been constructed. That is, pour floor concrete on the upper and lower sealing pipes. In the later decoration stage, decorative gypsum board is used to detachably connect to the wall to seal the parts of the pipes and fix the pipes.

[0046] By adopting the above technical solution, during construction, self-adhesive waterproof membrane is used to waterproof the foundation slab and walls, concentrating leaks at the joints between the foundation slab and walls and determining drainage points. Then, a lower sealing pipe is embedded at the joint, completely covering the connection. A horizontal drainage board is then laid on the surface of the foundation slab, covering the lower sealing pipe, thus securing it to the foundation slab. Similarly, an upper sealing pipe is embedded at the joint between the structural floor slab and walls, completely covering the connection. Next, concrete is poured onto both the foundation slab and the structural floor slab, but the areas for the upper and lower sealing pipes are left unpoured. Cement mortar is poured over the upper sealing pipe to secure it to the structural floor slab and protect it.

[0047] Several sleeves are pre-embedded at intervals along the direction of the upper cover pipe on the structural floor slab. An installation pipe is then inserted into each sleeve, with a sealing sleeve on the outer wall of the installation pipe abutting against the inner wall of the sleeve to achieve a seal. A flexible hose at the bottom of the installation pipe is then inserted into a fixed pipe, connecting the hose to the fixed pipe. The bottom of the fixed pipe is fixedly connected to the lower cover pipe via a connecting ring, completing the installation of the installation pipe between the upper and lower cover pipes. Vertical drainage boards are bolted to the wall drainage locations. A cement pressure plate is then fixed to the surface of the vertical drainage board away from the wall to reinforce the overall structure. The wall surfaces between adjacent vertical drainage boards are then plastered.

[0048] Finally, after observing that there is no leakage on the outside of the wall and that the drainage is unobstructed, the unfinished parts of the foundation slab and structural floor slab with concrete flooring are filled in. That is, concrete flooring is poured on the upper and lower cover pipes. The upper and lower cover pipes are then processed. In the later decoration stage, decorative gypsum board is used. The decorative gypsum board is set vertically and can be detachably connected to the wall. The installation pipe and fixing pipe are located between the decorative gypsum board and the wall, which conceals the installation pipe and fixing pipe and makes it more aesthetically pleasing.

[0049] In summary, this application includes at least one of the following beneficial effects:

[0050] 1. When water seeps into the wall, it flows along the wall to the connection point between the wall and the structural floor slab, specifically into the upper cover pipe. The water then flows into the connecting pipe. When the water reaches the guide component, it is directed to the storage tank. As the water accumulates in the storage tank and reaches its opening, it overflows. A portion of this overflows through the filter plate into the clean water zone. During this process, the filter plate filters the water, allowing only water to pass through while impurities remain in the storage tank. The remaining water flows back into the wastewater zone, then is guided back to the storage tank by the guide component, until it finally passes through the filter plate and enters the clean water zone.

[0051] 2. After the guide component guides the water from the wastewater area into the storage tank, the water in the storage tank will directly pass through the filter holes into the clean water area. Impurities in the water cannot pass through the filter holes, so the impurities are left in the storage tank, increasing the rate at which the drier water is discharged into the clean water area and improving the drainage efficiency.

[0060] Referring to Figure 1 and Figure 2 A lower cover pipe 20 is arranged horizontally on the foundation bottom plate 110, the lower cover pipe 20 is located at a connecting position of the foundation bottom plate 110 and the wall body 120 and completely covers the connecting position, a horizontal drainage plate 140 is laid on an upper surface of the foundation bottom plate 110, and the horizontal drainage plate 140 also covers an upper surface of the lower cover pipe 20, so that the lower cover pipe 20 is fixed and installed on the foundation bottom plate 110. An upper cover pipe 10 is arranged horizontally on the structural floor 90, the upper cover pipe 10 is located at a connecting position of the structural floor 90 and the interior wall 122 and completely covers the connecting position. Cement mortar 130 is poured on the upper cover pipe 10, so that the upper cover pipe 10 is fixed on the structural floor 90 and also protected.

[0061] Referring to Figure 1 and Figure 2A plurality of sleeves 80 are reserved on the structural floor 90, the sleeves 80 are arranged along the length direction of the upper cover pipe 10, the sleeves 80 pass through the structural floor 90, and the top end of the sleeve 80 is communicated with the upper cover pipe 10, the connecting pipe 30 is inserted into each sleeve 80 and communicated with the sleeve 80, and the connecting pipe 30 is vertically arranged, the bottom end of the connecting pipe 30 is communicated with the lower cover pipe 20, that is, the plurality of connecting pipes 30 are communicated with the upper cover pipe 10 and the lower cover pipe 20, and the water leakage flow path is that the water flows along the vertical drainage plate 123 into the upper cover pipe 10, then enters the sleeve 80, and then enters the lower cover pipe 20 through the connecting pipe 30, and finally is discharged through the horizontal drainage plate 140.

[0062] With reference to Figure 3 And Figure 4 In order to avoid that impurities in the water accumulate in the connecting pipe 30 and block the connecting pipe 30, affecting the drainage efficiency, a storage tank 50 with an open top is arranged in the connecting pipe 30, the side wall of the storage tank 50 is fixedly connected with the inner wall of the connecting pipe 30 on three sides, a plurality of filter holes 51 are arranged in the side wall of the storage tank 50, and the diameter of the filter holes 51 is smaller than the diameter of the impurities in the water. A guide assembly 40 is arranged in the connecting pipe 30, the bottom end of the guide assembly 40 is inclined downward, the connecting pipe 30 is divided into a sewage area at the top and a clean water area at the bottom, the storage tank 50 is located in the clean water area, the bottom end of the guide assembly 40 is inserted into the opening of the storage tank 50, and the guide assembly 40 is used for guiding all the water in the sewage area into the storage tank 50. A filter plate 52 is horizontally arranged at the open top of the storage tank 50, the filter plate 52 is fixedly connected with the storage tank 50, the filter plate 52 is located below the guide assembly 40, and the filter plate 52 blocks the opening of the storage tank 50 below the guide assembly 40.

[0063] When the wall 120 seeps water, the water flows along the wall 120 to the connection between the wall 120 and the structural floor 90, that is, in the upper cover pipe 10, then the water flows into the connecting pipe 30 through the sleeve 80, when the water flows to the guide assembly 40, the guide assembly 40 guides the water into the storage tank 50, the water directly passes through the filter holes 51 into the clean water area, and the impurities in the water cannot pass through the filter holes 51, so that the impurities are left in the storage tank 50, when the impurities accumulate too much, the filter holes 51 are easily blocked, the water circulation is affected, the impurities are stored in the storage tank 50, and the subsequent water will overflow from the opening of the storage tank 50 when the water accumulates at the opening of the storage tank 50, part of the water will pass through the filter plate 52 into the clean water area, in this process, the filter plate 52 filters the water, so that only the water can flow through the filter plate 52, and the impurities in the water are left in the storage tank 50. Another part of the water will re-enter the sewage area and then be guided into the storage tank 50 by the guide assembly 40, and then enter the clean water area through the filter plate 52.

[0064] With reference to Figure 3 And Figure 4 , the guide assembly 40 simultaneously plays a blocking role on the water in the sewage area, so that the water in the sewage area must pass through the storage tank 50 to reach the clean water area, and the water in the storage tank 50 must also pass through the filter plate 52 to enter the clean water area, so that impurities are stored in the storage tank 50, so that there is no impurities between the storage tank 50 and the inner wall of the connecting pipe 30 in the clean water area, that is, there is always a section of the connecting pipe 30 that does not appear impurities, thereby preventing the connecting pipe 30 from being affected by impurities and being blocked, and preventing the drainage efficiency from being affected.

[0065] With reference to Figure 3 And Figure 4 , the guide assembly 40 includes a driving wheel 41, a driven wheel 42 and a conveyor belt 43, the driving wheel 41 and the driven wheel 42 are both rotationally connected to the inner wall of the connecting pipe 30, the driven wheel 42 is located on the side of the central axis of the connecting pipe 30 away from the driving wheel 41, the driven wheel 42 is located below the driving wheel 41 and at the opening of the storage tank 50.

[0066] With reference to Figure 3 And Figure 4 , the driving wheel 41 is coaxially fixed with a rotating rod 44, the end of the rotating rod 44 penetrates out of the connecting pipe 30, and is connected in series with the driving wheels 41 in the connecting pipes 30, and is coaxially fixed with all the driving wheels 41. A gasket is added at the connection where the rotating rod 44 penetrates out of the connecting pipe 30 to achieve sealing. The conveyor belt 43 is sleeved on the driving wheel 41 and the driven wheel 42, the driving wheel 41 rotationally drives the conveyor belt 43 to move, a plurality of flow-through holes 431 are penetratingly formed on the conveyor belt 43, and the diameter of the flow-through holes 431 is smaller than the diameter of the impurities in the water. The sewage area is located above the conveyor belt 43, and the clean water area is located below the conveyor belt 43.

[0067] When the water moves along the connecting pipe 30 in the direction of the cover pipe 20, the water will first fall on the conveyor belt 43, the water will directly pass through the flow-through holes 431 into the clean water area, and the impurities in the water will not be able to pass through the flow-through holes 431, thereby being left on the upper surface of the conveyor belt 43. Then the rotating rod 44 is driven to rotate, so that the driving wheel 41 rotates to drive the conveyor belt 43 to move, so that the conveyor belt 43 drives the impurities left on the conveyor belt 43 to move in the direction of the storage tank 50, and then falls into the storage tank 50 from the edge of the conveyor belt 43, so that the impurities will not accumulate on the conveyor belt 43, reducing the possibility that the inner wall of the connecting pipe 30 and the conveyor belt 43 will be filled with impurities and the connecting pipe 30 will be blocked, thereby not affecting the drainage.

[0068] With reference to Figure 3 And Figure 4In order to prevent impurities from accumulating between the bottom of the conveying belt 43 and the inner wall of the connecting pipe 30, a plurality of poking rods 432 are fixed on the conveying belt 43, and the distance between the plurality of poking rods 432 is less than the diameter of the impurities in the water. The distance between the end of the conveying belt 43 and the inner wall of the connecting pipe 30 is equal to the length of the poking rod 432, so that the conveying belt 43 can drive the poking rod 432 to abut against the inner wall of the connecting pipe 30 during movement of the conveying belt 43.

[0069] The water enters the storage tank 50 from the top opening of the storage tank 50, and the movement of the conveying belt 43 also sends the impurities to the opening of the storage tank 50, so that the impurities in the water and the impurities on the conveying belt 43 are all gathered at the bottom end of the conveying belt 43, thereby making it easy for impurities to accumulate between the bottom end of the conveying belt 43 and the inner wall of the connecting pipe 30. During the movement of the conveying belt 43, the plurality of poking rods 432 are also moved, and when the poking rods 432 move to the bottom end of the conveying belt 43, the impurities accumulated through the bottom of the conveying belt 43 are stirred and dispersed, and part of the impurities are pushed into the storage tank 50, so that the accumulated impurities are loose and fall into the storage tank 50, thereby preventing the opening of the storage tank 50 from being easily blocked and affecting the drainage.

[0070] Referring to Figure 3 and Figure 4 When the impurities are stuck between adjacent poking rods 432, in order to prevent the impurities from entering the clean water area, a plurality of cleaning rods 60 are fixed on the side wall of the filter plate 52 close to the conveying belt 43, the cleaning rods 60 are staggered with the poking rods 432, that is, the poking rods 432 can pass through between adjacent cleaning rods 60, and the end of the cleaning rod 60 away from the filter plate 52 abuts against the side wall of the conveying belt 43. A plurality of cleaning rods 60 are also fixed on the inner wall of the connecting pipe 30, and the cleaning rods 60 connected with the connecting pipe 30 are located at the top of the conveying belt 43, and are used to fill the distance between the top end of the conveying belt 43 and the inner wall of the connecting pipe 30.

[0071] When the poking rod 432 moves to the bottom of the conveying belt 43, the poking rod 432 moves to the bottom of the conveying belt 43 with the center axis of the driven wheel 42 as the axis, and in this process, each poking rod 432 passes through between adjacent cleaning rods 60 from top to bottom, so that the impurities embedded between adjacent poking rods 432 are scraped by the cleaning rod 60 to the upper surface of the cleaning rod 60, thereby the cleaning rod 60 plays a cleaning role on the poking rod 432, and also makes the poking rod 432 not carry the impurities to the bottom of the conveying belt 43 and fall into the clean water area, thereby preventing the impurities in the clean water area of the connecting pipe 30 from blocking the connecting pipe 30, that is, the drainage is not affected.

[0072] Referring to Figure 3 and Figure 4The cleaning rod 60 on the connecting pipe 30 makes the impurities in the sewage area not easy to move directly from the distance between the top end of the conveying belt 43 and the connecting pipe 30 to the clean water area, that is, the impurities are blocked above the cleaning rod 60, when the pushing rod 432 moves to this position driven by the conveying belt 43, the pushing rod 432 moves from bottom to top relative to the cleaning rod 60 at this position, so as to push the impurities of the cleaning rod 60 to the upper surface of the conveying belt 43, and then transported to the storage box 50 by the conveying belt 43, thereby ensuring the cleanliness of the area in the clean water area except the storage box 50.

[0073] With reference to Figure 1 And Figure 3 When the storage box 50 accumulates more impurities, in order to prevent the impurities from accumulating upwards to the conveying belt 43 and affecting the flow of water, it is necessary to clean the connecting pipe 30 regularly. The connecting pipe 30 includes a mounting pipe 31, a hose 312 and a fixed pipe 32. The mounting pipe 31 is vertically arranged, and the top end of the mounting pipe 31 can be inserted into the sleeve 80. A sealing sleeve 311 is fixedly sleeved on the mounting pipe 31, and the sealing sleeve 311 is located at the top of the mounting pipe 31. When the mounting pipe 31 is inserted into the sleeve 80, the sealing sleeve 311 deforms into the sleeve 80, that is, it is in interference fit with the mounting pipe 31 and the sleeve 80, so as to always apply extrusion force to the inner wall of the sleeve 80, so that the sealing sleeve 311 is tightly attached to the inner wall of the sleeve 80, thereby sealing the sleeve 80 and preventing water from directly flowing out of the sleeve 80. The storage box 50 and the guide assembly 40 are both located in the mounting pipe 31, so that when the water in the sleeve 80 enters the mounting pipe 31, it will be quickly filtered by the storage box 50, thereby preventing impurities from accumulating in the mounting pipe 31.

[0074] With reference to Figure 1 And Figure 3 The hose 312 is located at the bottom of the mounting pipe 31, the top end of the hose 312 is inserted into the mounting pipe 31, and the outer wall of the hose 312 is fixedly attached to the inner wall of the mounting pipe 31. The fixed pipe 32 is vertically arranged and located below the mounting pipe 31. The bottom end of the fixed pipe 32 is fixed on the lower cover pipe 20 and communicates with the lower cover pipe 20. When the water in the upper cover pipe 10 flows into the sleeve 80, enters the mounting pipe 31, and then enters the hose 312 along the mounting pipe 31, the water in the hose 312 will directly enter the fixed pipe 32 without leakage, and then enter the lower cover pipe 20 and be discharged.

[0075] With reference to Figure 1 And Figure 3When the impurities in the storage tank 50 accumulate too much, the mounting pipe 31 can be moved up and down, then manually move the mounting pipe 31 downward until the mounting pipe 31 is separated from the sleeve 80, then translate the mounting pipe 31 in the horizontal direction, so that the hose 312 is deformed and directly separated from the fixed pipe 32. Then reverse the direction of the water flow in the mounting pipe 31 to flush the impurities in the mounting pipe 31 out of the opening at the end of the mounting pipe 31 close to the sealing sleeve 311, thereby achieving regular cleaning of the mounting pipe 31.

[0076] Then the new mounting pipe 31 is in the vertical direction and is moved directly below the sleeve 80, then move the mounting pipe 31 upward so that the top end of the new mounting pipe 31 is inserted into the sleeve 80, then deform the hose 312 to facilitate insertion into the fixed pipe 32, thereby achieving replacement of the mounting pipe 31, solving the problem of impurities accumulating in the sewage area when the storage tank 50 accumulates more, and avoiding affecting the drainage.

[0077] Referring to Figure 3 and Figure 5 In order to increase the stability of the mounting pipe 31 installed on the upper cover pipe 10 and the fixed pipe 32, a connecting assembly 70 is provided on the fixed pipe 32 for fixedly connecting the bottom of the mounting pipe 31 with the fixed pipe 32, the connecting assembly 70 includes a connecting ring 71 and a connecting block 72, the connecting ring 71 is fixedly sleeved on the fixed pipe 32 and located at the top of the fixed pipe 32, part of the top of the connecting ring 71 is higher than the fixed pipe 32, a connecting hole 711 is formed in the inner wall of the connecting ring 71, the connecting block 72 is inserted into and movable in the connecting hole 711, a connecting spring 73 is arranged in the connecting hole 711 and located between the connecting block 72 away from the central axis of the connecting ring 71 and the inner wall of the connecting hole 711, one end of the connecting spring 73 is fixed with the connecting block 72 and the other end is fixed with the inner wall of the connecting hole 711, a connecting rod 74 is fixed on the connecting block 72, one end of the connecting rod 74 extends out of the outer wall of the connecting ring 71, pulling the connecting rod 74 can drive the connecting block 72 to move, and a mounting hole 313 is formed in the outer side wall of the mounting pipe 31.

[0078] Referring to Figure 3 and Figure 5When the top end of the installation pipe 31 is inserted into the sleeve 80, and the bottom hose 312 is also inserted into the fixed pipe 32, then the connecting rod 74 is manually pulled to compress the connecting spring 73 and be accommodated in the connecting hole 711, and then the position of the installation pipe 31 is adjusted up and down to align the installation hole 313 with the connecting block 72, the force of pulling the connecting rod 74 is released, the connecting spring 73 restores the deformation to push the connecting block 72 towards the installation pipe 31 until the connecting block 72 is inserted into the installation hole 313, and the side wall of the connecting block 72 abuts against the inner wall of the installation hole 313 to limit and support, so that the installation pipe 31 is fixedly connected with the connecting ring 71 to achieve the installation of the installation pipe 31. When the middle water of the upper cover pipe 10 flows into the sleeve 80, enters the installation pipe 31, and then enters the hose 312 along the installation pipe 31, because the hose 312 is directly inserted into the fixed pipe 32, the water in the hose 312 directly enters the fixed pipe 32 and does not leak, and then enters the lower cover pipe 20 from the fixed pipe 32 and is discharged.

[0079] If the installation pipes 31 are connected by the rotating rod 44, the installation pipes 31 are located on the same straight line, that is, when the height of one installation pipe 31 is determined to align the installation hole 313 with the connecting block 72, the installation holes 313 on the remaining installation pipes 31 are aligned with the corresponding connecting blocks 72, so that the installation of the installation pipes 31 is facilitated.

[0080] The implementation principle of the deep foundation pit basement drainage system and the construction method is that when the wall 120 leaks, water flows along the wall 120 to the connection between the wall 120 and the structural floor 90, that is, in the upper cover pipe 10, and then flows into the connecting pipe 30, and when the water flows to the guide assembly 40, the guide assembly 40 guides the water into the storage tank 50. When the water in the storage tank 50 accumulates at the opening of the storage tank 50, the water overflows from the opening of the storage tank 50, part of the water passes through the filter plate 52 into the clean water area, and in this process, the filter plate 52 filters the water, so that only water can flow through the filter plate 52, and impurities in the water are left in the storage tank 50. Another part of the water reenters the sewage area and then is guided by the guide assembly 40 into the storage tank 50, and then enters the clean water area through the filter plate 52.

[0081] The guide assembly 40 also blocks the water in the sewage area, so that the water in the sewage area must pass through the storage tank 50 to reach the clean water area, and the water in the storage tank 50 must pass through the filter plate 52 to enter the clean water area, so that impurities are stored in the storage tank 50, so that impurities are not easy to appear between the inner wall of the storage tank 50 and the connecting pipe 30 in the clean water area, and the connecting pipe 30 is not easy to be affected by impurities and be blocked, so that the drainage is not easy to be affected.
