Description

Technical Field

[0001] The present invention belongs to the technical field of basement pressure relief, and particularly relates to a basement anti-floating and pressure-limiting filter layer connection system and a construction method thereof. Background Art

[0002] The basement anti-floating and pressure relief system is an engineering measure used to prevent the basement from floating or leaking due to excessive groundwater pressure. Its principle is to set pressure relief holes or drainage channels to timely drain the accumulated groundwater, reduce the buoyancy of groundwater on the underground structure, and thus effectively prevent the basement structure from being lifted by water pressure or causing leakage. The function of this system is to ensure the stability of the basement, prevent water disasters from damaging the underground space, and improve the safety and durability of the building.

[0003] Chinese Patent with Application No. 202011085600.4 discloses a device and a construction method for basement anti-floating and pressure relief equipment, including a basement floor slab, a water storage tank and a foundation soil layer. The basement floor slab is provided above the foundation soil layer, a water storage tank is provided on one side of the foundation soil layer, a filter pipe network is provided inside the foundation soil layer, a water collecting pipe is inserted inside the filter pipe network, a drain pipe is installed inside the basement floor slab, the water collecting pipe is connected to the drain pipe, and a first sedimentation partition is provided at the bottom of the inner wall of the water storage tank and close to one side of the drain pipe. Water precipitates under the action of gravity for secondary sedimentation. After sedimentation, the water overflows the second sedimentation partition and flows under the floating plate. When the water level reaches a certain height, the floating plate touches the touch switch to turn on the power supply of the high-pressure water pump. The high-pressure water pump pumps away the clear water under the action of the floating plate and the protective filter cylinder. Through multiple sedimentation and clarification, the upper clear water is convenient for direct utilization and use, avoiding resource waste caused by multiple treatments.

[0004] Regarding the basement anti-floating and pressure relief method, usually a gravel layer is used as the filter layer. However, after a long time of use, the soil and fine particles carried by groundwater will adhere to the gravel, resulting in pore blockage, and seriously, it will cause damage to the basement structure. At the same time, the gravel layer is generally buried deeper, making it impossible to quickly carry out cleaning and maintenance work. Moreover, when the system is blocked, if it cannot be quickly detected and emergency pressure relief cannot be carried out, there is still a risk of damaging the basement structure. When draining water, if the water pressure suddenly increases due to an emergency, although the drainage system is draining water, it is no longer possible to quickly carry out pressure relief operations, which may lead to damage to the basement structure.

[0010] A limiting ring is fixedly provided on the inner wall of the connection between the pressure relief pipe and the sedimentation bucket. An adjusting piston is slidably connected to the inner side wall of the pressure relief pipe. The bottom of the adjusting piston is fixedly connected to the inner bottom of the sedimentation bucket through a return spring.

[0011] Further, the first water pipe is a tee pipe, and check valves are installed on both branches of the first water pipe that are far from the pressure relief pipe. The check valves allow water to enter the inside of the well body; a first water pump is installed at the end of the upward-facing branch of the first water pipe.

[0012] Further, a second water pump is installed inside the well body, and the water outlet end of the second water pump is communicated with the outside of the basement through a drain pipe.

[0023] S4. Weld the first water pipe to the pressure relief pipe inside the well body. After installing the water pump circuit components, insert the rotating cylinder into the rotating groove, and then install and fix the top ring cover on the top of the gravel filter layer groove.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] (1) Through the connection and cooperation between the filter layer mechanism and the well body, the present invention can not only ensure that the water body in the well body can flow back to the ground through the filter layer mechanism to solve the blockage, but also enable the flowing-back water body to better wash away impurities such as soil adhered to the gravel, achieving the effect of cleaning impurities; and it facilitates the staff to quickly maintain and clean the gravel filter layer; specifically, when the groundwater pressure becomes small, the water body remaining in the well body flows back to the ground through the filter layer mechanism in the reverse direction. At this time, due to some soil and fine particles remaining on the gravel at the bottom of the gravel filter layer groove, the water body cannot flow back. At this time, the rotating cylinder is controlled by the motor to rotate, so that the spiral blade rotates, which can not only stir the gravel with soil adhered to the bottom, make the bottom of the gravel filter layer groove active and have a flowing space, thereby ensuring that the water body in the well body can flow back to the ground through the filter layer mechanism to solve the blockage, but also enable the flowing-back water body to better wash away impurities such as soil adhered to the gravel, achieving the effect of cleaning impurities; and, through the rotation of the spiral blade, the clean gravel at the top circulates to the bottom of the gravel filter layer groove, and the gravel with soil adhered to the bottom is lifted to the top, facilitating the staff to quickly maintain and clean the gravel filter layer. By flushing water into the top of the gravel filter layer groove, the sludge is washed back to the ground, or the gravel with impurities adhered to it can be directly taken out and cleaned.

[0026] (2) Through the cooperation between the filter layer mechanism, the well body and the water inlet pipe, the present invention can not only quickly detect the blockage problems of the filter layer mechanism and the water inlet pipe, but also perform emergency pressure relief to avoid damage to the basement; specifically, when the system is depressurized, if the filter element of the water inlet pipe is blocked, the water body can be temporarily filtered through a certain height of gravel in the gravel filter layer groove, and the water body enters the well body through the overflow hole to achieve pressure relief; if the gravel filter layer groove is blocked, it can be dredged through the lifting mechanism, thereby avoiding damage to the basement; at the same time, the blockage situation can be quickly judged through the water level in the gravel filter layer groove and the water level in the well body.

[0027] (3) By adjusting the cooperation between the piston and the first water pipe and the second water pipe, the present invention can not only perform emergency pressure relief for the increased water pressure in case of emergency, but also automatically adjust the pressure relief method under different water pressure conditions, avoiding the problems of power consumption and short service life caused by frequent use of the water pump. Specifically, when the groundwater pressure at the bottom of the basement increases, the water body enters the sedimentation bucket from the water inlet pipe and pushes the adjusting piston to move upward inside the pressure relief pipe and pulls the return spring, so that the pressure relief pipe is first communicated with the second water pipe, and the water body enters the well body from the sedimentation bucket through the second water pipe for pressure relief, preventing the damage of the building complex structure caused by the increase of the groundwater pressure under the basement of the building complex. When the water pressure increases rapidly in case of emergency and the flow rate of the second water pipe can no longer meet the pressure relief requirement of the groundwater, the rapidly increasing water pressure forces the adjusting piston to continue to move upward inside the pressure relief pipe and pull the return spring, so that the first water pipe is communicated with the pressure relief pipe, and the water body enters the well body from the first water pipe for auxiliary pressure relief, achieving the purpose of rapid pressure relief under the cooperation of the first water pipe and the second water pipe. When the pressure cannot be reduced with the cooperation of the first water pipe, the water pressure forces the adjusting piston to continue to move upward and pull the return spring, so that the adjusting piston reaches the top of the pressure relief pipe to trigger the contact switch, and the first water pump is controlled to start through the contact switch to assist in pumping water, so as to achieve rapid pressure reduction. At the same time, through the cooperation between the adjusting piston and the pressure relief pipe of the present invention, the pressure relief under different pressures can be satisfied, avoiding the problems of power consumption and short service life caused by frequent use of the water pump.

[0028] (4) By adjusting the cooperation between the piston and the return spring and the limit ring, the present invention can not only realize the automatic reverse drainage inside the well body when the water pressure is small, avoiding the accumulation of impurities in the well body during the pumping process and being difficult to clean, but also quickly promote the discharge of impurities to prevent blockage. Specifically, when the water pressure is large, it acts on the adjusting piston and the sealing disc, causing the adjusting piston to move upward. At this time, due to the action of the one-way valve inside the adjusting piston, the adjusting piston is a closed whole, so as to realize the upward movement of the adjusting piston controlled by the water pressure to achieve pressure relief. When the water pressure is small and pressure relief is not required, through the reset action of the return spring of the present invention, the sealing disc is pulled downward to disengage from the bottom groove, so that the water body inside the well can be discharged into the water passing hole and the bottom hole inside the adjusting piston through the second water pipe, and finally the reverse flow of the water body is realized, so that the water body penetrates backward into the soil from the water inlet pipe of the sedimentation bucket, thus realizing the automatic reverse drainage inside the well body when the water pressure is small and avoiding the pumping process. At this time, the impurities inside the well will flow backward into the sedimentation bucket and be precipitated and collected in the sedimentation bucket, avoiding the accumulation of impurities in the well body and being difficult to clean. At the same time, when the sealing disc moves downward, the sliding rod slides downward to make the control rod rotate on the hinge groove. During the rotation of the control rod, one end will slide in the sliding groove, and finally drive the pushing disc to push downward, which can quickly promote the discharge of impurities in the bottom hole to prevent blockage.

[0045] Embodiment

[0046] As Figures 1 to 12 shown, a basement anti - floating pressure - limiting filter layer connection system includes a well body 100 and a filter layer mechanism 900. A pressure relief pipe 700 is fixedly connected to the middle of the bottom of the well body 100. The bottom of the pressure relief pipe 700 is fixedly connected to a precipitation bucket 200. A plurality of water inlet pipes 210 are evenly and fixedly connected to the periphery of the precipitation bucket 200, and a filter element is installed in the water inlet pipe 210. The filter layer mechanism 900 includes a gravel filter layer groove 910, and the gravel filter layer groove 910 is inserted outside the well body 100. The inner bottom of the gravel filter layer groove 910 is fixedly connected to the corresponding water inlet pipe 210. The outer bottom of the gravel filter layer groove 910 is fixedly connected to a filter cloth groove 911, and a filter cloth 920 is filled in the filter cloth groove 911. A rotating groove 913 is fixedly provided in the middle of the inner bottom of the gravel filter layer groove 910, and a lifting mechanism 930 is rotatably connected to the rotating groove 913.

[0047] Through the connection and cooperation between the filter layer mechanism 900 and the well body 100, the present invention can not only ensure that the water in the well body 100 can flow back to the ground through the filter layer mechanism 900 to solve the blockage, but also enable the flowing-back water to better wash away impurities such as soil adhering to the gravel, achieving the effect of cleaning impurities; and it facilitates the staff to quickly maintain and clean the gravel filter layer; a detailed description will be given later.

[0048] Further, the lifting mechanism 930 includes a rotating cylinder 931, the bottom of the rotating cylinder 931 is rotatably connected to the rotating groove 913, a spiral blade 932 is fixedly arranged on the side wall of the rotating cylinder 931, and an external gear ring 933 is fixedly arranged outside the top of the rotating cylinder 931; a top ring cover 940 is fixedly installed on the outer side wall of the gravel filter layer groove 910, a motor 941 is installed on the top ring cover 940 through a bracket, and the gear on the output shaft of the motor 941 meshes with the external gear ring 933; a plurality of overflow holes 912 are commonly formed through the upper side of the insertion side of the gravel filter layer groove 910 and the well body 100.

[0049] When the groundwater pressure becomes small in the present invention, the water retained in the well body 100 flows back to the ground in the reverse direction through the filter layer mechanism 900. At this time, due to some soil and fine particles remaining in the gravel at the bottom of the gravel filter layer groove 910, the water body cannot flow back. At this time, the rotating cylinder 931 is controlled to rotate by the motor 941, so that the spiral blade 932 rotates, which can not only stir the gravel with soil adhered to the bottom, make the bottom of the gravel filter layer groove 910 active and have a flowing space, thereby ensuring that the water in the well body 100 can flow back to the ground through the filter layer mechanism 900 to solve the blockage, but also enable the flowing-back water to better wash away impurities such as soil adhering to the gravel, achieving the effect of cleaning impurities; and, through the rotation of the spiral blade 932, the clean gravel at the top is circulated to the bottom of the gravel filter layer groove 910, and the gravel with soil adhered to the bottom is lifted to the top, which facilitates the staff to quickly maintain and clean the gravel filter layer. By flushing water into the top of the gravel filter layer groove 910, the sludge is washed back to the ground, or the gravel with impurities adhered to it can be directly taken out and cleaned.

[0050] Through the cooperation between the filter layer mechanism 900, the well body 100 and the water inlet pipe 210, the present invention can not only quickly detect the blockage problems of the filter layer mechanism 900 and the water inlet pipe 210, but also perform emergency pressure relief to avoid damage to the basement; specifically, when the system is depressurized, if the filter element of the water inlet pipe 210 is blocked, the water body can be temporarily filtered through a certain height of gravel in the gravel filter layer groove 910, and the water body enters the well body 100 from the overflow hole 912 to achieve emergency pressure relief; if the gravel filter layer groove 910 is blocked, it can be dredged through the lifting mechanism 930, thereby avoiding damage to the basement; at the same time, the blockage situation can be quickly judged by the water level in the gravel filter layer groove 910 and the water level in the well body 100.

[0051] Furthermore, the top of the pressure relief pipe 700 is closed and installed with a contact switch 710. A plurality of first water pipes 500 are uniformly and fixedly communicated with the side wall of the pressure relief pipe 700 inside the well body 100, and a first water pump 600 is installed on the first water pipe 500. A plurality of second water pipes 300 are uniformly and fixedly communicated with the side wall of the pressure relief pipe 700 outside the well body 100, and the other ends of the second water pipes 300 are fixedly communicated with the bottom of the well body 100.

[0052] A limiting ring 220 is fixedly arranged on the inner wall of the connection between the pressure relief pipe 700 and the sedimentation bucket 200. A regulating piston 800 is slidably connected to the inner side wall of the pressure relief pipe 700, and the bottom of the regulating piston 800 is fixedly connected to the inner bottom of the sedimentation bucket 200 through a return spring 810.

[0053] Through the cooperation of the regulating piston 800 with the first water pipe 500 and the second water pipe 300, the present invention can not only perform emergency pressure relief for the increased water pressure in case of emergency, but also automatically adjust the pressure relief method under different water pressure conditions, avoiding the problems of power consumption and short service life caused by the frequent use of the water pump; detailed description will be made later.

[0054] It should be noted that the power equipment such as the contact switch 710 and the first water pump 600 of the present invention are all provided by an external power supply, which is a conventional setting and will not be described in detail herein.

[0055] Furthermore, the first water pipe 500 is a tee pipe, and check valves are installed on both branches of the first water pipe 500 away from the pressure relief pipe 700, and the check valves allow water to enter the well body 100. The first water pump 600 is installed at the end of the upward branch of the first water pipe 500.

[0056] When the groundwater pressure at the bottom of the basement increases in the present invention, water enters the sedimentation barrel 200 from the water inlet pipe 210, pushes the regulating piston 800 to move upward inside the pressure relief pipe 700, and pulls the return spring 810, so that the pressure relief pipe 700 is first communicated with the second water pipe 300, and the water body enters the inside of the well body 100 from the sedimentation barrel 200 through the second water pipe 300 for pressure relief, preventing the damage of the building complex structure caused by the increase of groundwater pressure under the basement of the building complex; when encountering an emergency with a rapid increase in water pressure, the flow rate of the second water pipe 300 can no longer meet the pressure relief requirements of the groundwater. At this time, the rapidly increasing water pressure forces the regulating piston 300 to continue to move upward inside the pressure relief pipe 700 and pull the return spring 810, so that the first water pipe 500 is communicated with the pressure relief pipe 700, and the water body enters the well body 100 from the first water pipe 500 for auxiliary pressure relief. With the cooperation of the first water pipe 500 and the second water pipe 300, the purpose of rapid pressure relief is achieved; when the pressure cannot be reduced with the cooperation of the first water pipe 500, at this time, the water pressure forces the regulating piston 300 to continue to move upward and pull the return spring 810, so that the regulating piston 300 reaches the top of the pressure relief pipe 700 to trigger the contact switch 710, and the first water pump 600 is controlled to start through the contact switch 710, so that the first water pump 600 assists in pumping water, thereby realizing rapid decompression; at the same time, through the cooperation of the regulating piston 800 and the pressure relief pipe 700 of the present invention, the pressure relief under different pressures can be satisfied, avoiding the problems of power consumption and short service life caused by the frequent use of the water pump.

[0057] Further, a second water pump 400 is installed inside the well body 100, and the water outlet end of the second water pump 400 is communicated with the outside of the basement through a drain pipe 410.

[0058] When the water body in the well body 100 reaches the critical value, the second water pump 400 can be controlled by the induction device to pump the water body to the outside of the basement through the drain pipe 410, preventing the water body from overflowing and flooding the basement.

[0059] Further, a plurality of water through holes 820 are provided on the side wall of the regulating piston 800, and the water through holes 820 are communicated with each other; a one-way valve is installed on the water through holes 820, and the one-way valve allows water to enter the inside of the regulating piston 800;

[0060] A bottom groove 830 is formed in the middle of the bottom of the regulating piston 800, and the middle part of the bottom groove 830 is communicated with the water through holes 820 through a bottom hole 831.

[0061] Through the cooperation of the regulating piston 800 with the return spring 810 and the limit ring 220, the present invention can not only realize the automatic reverse drainage inside the well body 100 when the water pressure is small, avoid the accumulation of impurities in the well body 100 during the pumping process and make it difficult to clean, but also quickly promote the discharge of impurities to prevent blockage; a detailed description will be given later.

[0062] Further, a plurality of sliding holes 840 are evenly formed around the bottom groove 830. A sliding rod 860 is slidably connected to the sliding hole 840. The bottoms of the sliding rods 860 are fixedly connected together to form a closing disc 850. The bottom of the closing disc 850 is fixedly connected to a return spring 810.

[0063] Further, a hinge groove 861 is fixedly provided at the top of the sliding rod 860. The hinge groove 861 is hinged to the side wall of a control rod 870. A pushing disc 880 is arranged among a plurality of control rods 870. A plurality of sliding grooves 890 are fixedly provided corresponding to the side wall of the pushing disc 880. One end of the control rod 870 is horizontally slidably connected within the notch of the corresponding sliding groove 890.

[0064] When the water pressure is relatively high in the present invention, it acts on the adjusting piston 800 and the closing disc 850, causing the adjusting piston 800 to move upward. At this time, due to the action of the one-way valve within the adjusting piston 800, the adjusting piston 800 forms a closed whole, thereby realizing the upward movement of the adjusting piston 800 controlled by the water pressure to achieve pressure relief. When the water pressure is relatively low and pressure relief is not required, through the reset action of the return spring 810 of the present invention, the closing disc 850 is pulled downward to disengage from the bottom groove 830, enabling the water in the well body 100 to be discharged into the water passing hole 820 and the bottom hole 831 within the adjusting piston 800 through the second water pipe 300, and finally realizing the reverse backflow of the water, so that the water deeply penetrates into the soil body in the reverse direction from the water inlet pipe 210 of the sedimentation bucket 200, thereby realizing the automatic reverse drainage inside the well body 100 when the water pressure is relatively low and avoiding the pumping link. At this time, the impurities in the well body 100 will flow back into the sedimentation bucket 200 in the reverse direction and are precipitated and collected in the sedimentation bucket 200, avoiding the accumulation of impurities in the well body 100 and being difficult to clean. Meanwhile, when the closing disc 850 moves downward, the control rod 870 rotates on the hinge groove 861 as the sliding rod 860 slides downward. During the rotation of the control rod 870, one end thereof will slide within the sliding groove 890, and finally drive the pushing disc 880 to push downward, which can quickly promote the discharge of the impurities in the bottom hole 831 and prevent blockage.

[0065] Further, the control rod 870 is an L-shaped rod. The L-shaped rod facilitates the rotation of the control rod 870 to drive the pushing disc 880 to move downward.

[0066] Further, inclined surface annular grooves 110 are fixedly communicated around the bottom of the well body 100. The bottom of the inclined surface annular grooves 110 is fixedly communicated with the second water pipe 300.

[0067] The inclined surface annular grooves 110 facilitate the guiding of impurities and promote the discharge of impurities.

[0068] A construction method using the above basement anti-floating pressure-limiting filter layer connection system comprises the following steps:

[0069] S1. Dig a well pit and install a gravel filter layer trough 910 in the well pit;

[0070] S2. Install a sedimentation bucket 200 and a pressure relief pipe 700, and weld and fix the second water pipe 300 to the pressure relief pipe 700; weld and fix both ends of the water inlet pipe 210 to the inner side of the gravel filter layer trough 910 and the sedimentation bucket 200 respectively;

[0071] S3. Sleeve the well body 100 on the pressure relief pipe 700, and weld and fix the connection parts of the pressure relief pipe 700, the second water pipe 300 and the well body 100 inside the well body;

[0072] S4. Weld the first water pipe 500 to the pressure relief pipe 700 inside the well body 100. After installing the water pump circuit components, insert the rotating cylinder 931 into the rotating groove 913, and then install and fix the top ring cover 940 on the top of the gravel filter layer trough 910.

[0073] Through the construction method of the present invention, the system can be quickly installed step by step, avoiding the large impact of equipment on the construction.

[0074] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the inventive concept of the present invention, several improvements and transformations can be made, and these all belong to the protection scope of the present invention.
