Description

Technical Field

[0001] This invention relates to the field of foundation pit support technology, specifically to an auxiliary drainage type foundation pit support component and its usage method. Background Technology

[0002] The main functions of foundation pit support are soil retention, water prevention, and drainage, as well as providing a safe space for construction within the pit. During operation, the support components primarily aim to prevent slope collapse, protect surrounding buildings and pipelines, and simultaneously guide groundwater to ensure that foundation engineering is carried out in a dry and stable environment. It is a crucial temporary engineering element for ensuring the safety of deep foundation pit operations. During the foundation pit support process, foundation pit support components are required. However, when these components are in operation, increased water pressure within the soil can cause excessive stress on the support structure, leading to deformation or collapse. Simultaneously, water seepage can carry away soil particles, causing piping and quicksand, resulting in soil strength loss. Therefore, timely water drainage is necessary. For rapid drainage, existing technologies, such as the Chinese utility model patent application with application number 202223340770.X and application date of 2022-12-12, propose a drainage structure... The first invention relates to a foundation pit support component. It utilizes a movable structure to address the challenge of manually assembling foundation pit components during rainy weather. This movable structure, triggered when water accumulates in the pit, moves the support plates to the sides, reinforcing the pit in a simple and safe manner. The second invention is a Chinese invention patent application (application number 202211087258.0, application date 2022-09-07), which describes a reinforced foundation pit support component that facilitates drainage. During operation, it features a drainage pipe with multiple inlet grooves. The diameter of the first drainage hole is smaller than that of the second drainage hole. The support plate has an adjustment component for driving the adjustment sleeve to rotate, and the adjustment sleeve contains a cleaning component for removing mud and sand, reducing drainage pipe blockage. The third invention is application number 202010612916.8. A deep foundation pit support component with an application date of 2020-06-30 is described. When in use, both the baffle and support components are installed quickly, and the water diversion component solves the problem of water seepage on the slope of the deep foundation pit. Compared with the traditional method of setting drainage ditches in the deep foundation pit, it increases the working surface of the foundation construction and reduces labor and material costs.

[0003] After the support components and anchors have been in operation for a long time, the water in the soil will repeatedly lubricate the contact surface, soften the surrounding soil, and generate pore water pressure that reduces the effective stress. This causes the holding force between the anchor and the soil to continuously decrease, leading to the anchor gradually loosening and failing. As a result, it is necessary to install anchors to assist in stabilizing the structure. If the anchor is not equipped with auxiliary stabilizing components during use, the anchor will not be able to compensate for the loss of holding force caused by water lubrication and soil softening. Over time, the anchoring force will continue to decay, and eventually the anchor may be pulled out or the entire structure may become unstable, causing the foundation pit to collapse. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary drainage type foundation pit support component and its usage method, in order to solve the problem mentioned in the background art that when the anchor rod is used, if an auxiliary stabilizing component is not installed in the subsequent process, the anchor rod will not be able to compensate for the loss of holding force caused by water lubrication and soil softening. As time goes by, the anchoring force will continue to decay, and eventually the anchor rod may be pulled out or the whole structure may become unstable, causing the foundation pit to collapse.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An auxiliary drainage type foundation pit support component includes a base plate, a side plate connected to the upper surface of the base plate via a support rod, a guide groove on the back of the side plate, and positioning anchors installed inside both the base plate and the side plate. An auxiliary anchor is also fixedly connected inside the side plate. A water guide pipe is fixedly connected inside the side plate, and a fixing plate is fixedly connected to the inner wall of the water guide pipe. A filter plate is connected inside the water guide pipe via a swing assembly. An inner plate is fixedly connected to the inner wall of the water guide pipe, and an air bladder is bonded to the surface of the inner plate. A long pin is connected to the fixing plate via a reciprocating assembly, and a brush is fixedly connected to the surface of the long pin. When the air bladder is in operation, air is supplied to the long pin via a hose. A side rod is connected to the auxiliary anchor via a release assembly.

[0007] Preferably, the swing assembly includes a connecting plate fixedly connected to the inner wall of the water guide pipe, and a telescopic rod is bolted to the surface of the connecting plate. A pressing plate is fixedly connected to the output end of the telescopic rod. In addition, the pressing plate is rotatably connected to the long pin, and a ball bearing is movably connected to the end of the long pin. The water guide pipe is inclined.

[0008] Preferably, the reciprocating assembly includes a drive motor fixedly connected to the surface of the extrusion plate, and the output end of the drive motor is fixedly connected to the long pin.

[0009] Preferably, the airbags are symmetrically distributed on both sides of the inner plate.

[0010] Preferably, the surface of the extrusion plate is in contact with the surface of the airbag, and an air intake pipe is fixedly connected to the upper surface of the airbag, and an output pipe is fixedly connected to the side of the airbag. In addition, the output pipe is connected to the long pin through a flexible tube, and the surface of the long pin is provided with air jets at equal intervals.

[0011] Preferably, a one-way valve is fixedly connected to both the surface of the intake pipe and the surface of the output pipe.

[0012] Preferably, the release assembly includes a connecting rod fixedly connected to the side of the extrusion plate, and the end of the connecting rod is fixedly connected to a working plate, and a push rod is movably disposed on the surface of the working plate.

[0013] Preferably, the auxiliary anchor rod has a sliding rod inside, and the end of the sliding rod is hemispherical, and the end of the sliding rod is initially in contact with the surface of the push rod.

[0014] Preferably, a limiting plate is fixedly connected to the surface of the slide rod, and the outer wall of the limiting plate is in contact with the inner wall of the auxiliary anchor rod. A connecting shaft is rotatably provided inside the auxiliary anchor rod, and a side rod is fixedly connected to the surface of the connecting shaft. A side block is fixedly connected to the inner wall of the side rod, and the side block is hemispherical. The lower surface of the slide rod is in contact with the surface of the side block.

[0015] A method for using an auxiliary drainage type foundation pit support component includes the following steps:

[0016] S1. During use, water seeping from the soil layer is discharged through the guide channel and water pipe. After a long period of use, the telescopic rod is activated. At this time, the telescopic rod drives the filter plate to swing through the swing component, so that no particles remain on the filter plate and the water is discharged better.

[0017] S2. When the telescopic rod is working, under the action of the reciprocating component, the long pin and the brush work inside the water pipe to reciprocate and efficiently unclog the water pipe, so that the water pipe drains more smoothly. At the same time, the airbag is also in working condition, and the airbag and the air jet play an auxiliary role in unblocking.

[0018] S3. When the telescopic rod is working, the sliding rod is directly pushed by the push rod, and the sliding rod directly pushes the side block, causing the side block and the side rod to rotate around the connecting shaft. Then the side rod opens from the inside of the auxiliary anchor and inserts into the soil layer, which plays the role of auxiliary positioning and loosening compensation, making the auxiliary anchor more stable when working.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] Employing a novel structural design, during normal operation, water within the soil layer is discharged through the water pipe. After prolonged use, when auxiliary stabilization of the base plate and side plates is required, the telescopic rod activates. During the operation of the telescopic rod, the filter plate vibrates under the action of the swing assembly, preventing impurities from remaining. Simultaneously, the long pin, under the action of the reciprocating assembly, drives the brush components and airbags to clear the water pipe, allowing for better water flow. Furthermore, the sliding rod is directly pushed by the push rod, which in turn pushes the side block, opening the side rod and thus assisting in securing the soil layer. This improves the stability of the auxiliary anchor rod, base plate, and side plates during operation. Specific details are as follows:

[0021] (1) When the auxiliary drainage type foundation pit support component is working normally, the water inside the soil layer is discharged through the water pipe. After long-term use, when it is necessary to stabilize the bottom plate and side plate, the telescopic rod is activated. During the operation of the telescopic rod, the filter plate is pushed directly through the extrusion plate, the long pin and the ball. The filter plate swings under the action of thrust and its own gravity, so that the impurities are shaken off. Thus, no impurities remain on the filter plate, which can better drain water.

[0022] (2) When the telescopic rod is working, the long pin is driven to move by the extrusion plate. During the movement of the long pin, the drive motor on the surface of the extrusion plate directly drives the long pin to rotate and then turn back. As a result, the long pin not only drives the brush part to move in the horizontal direction, but also drives the brush part to rotate. As a result, the brush part can efficiently unclog the water pipe and make the water pipe drain better.

[0023] Furthermore, as the extrusion plate moves, it directly compresses the airbag. When the airbag is compressed, air is expelled through the output pipe and the air nozzle. When the airbag is not compressed, air is inhaled through the intake pipe. Thus, the airbag and the air nozzle play an auxiliary role in clearing blockages.

[0024] (3) When the expansion rod initially moves the compression plate, the compression plate moves the working plate and push rod through the connecting rod. The push rod directly pushes the sliding rod, which in turn pushes the side block. Then the side block and the side rod rotate around the connecting shaft, and the side rod opens from the inside of the auxiliary anchor rod and inserts into the soil layer, which increases the insertion area and helps stabilize the auxiliary anchor rod. This makes the auxiliary anchor rod more stable when it is working. If the side rod is directly made to work in the initial state, it will directly crush the surrounding soil, causing the soil to lose strength like tofu dregs, which will reduce the stability. In the later stage, when the soil layer is loosened due to moisture, the side rod will unfold to protect the integrity of the soil and automatically compensate for the holding force when it is loosened, thus achieving dynamic self-locking and having the effect of loosening compensation.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figures 1-4 The present invention provides the following technical solution: an auxiliary drainage type foundation pit support component.

[0038] Includes a base plate 1, the upper surface of the base plate 1 is connected to a side plate 2 by a support rod, and a guide groove 28 is provided on the back of the side plate 2. Positioning anchor rods are provided inside the base plate 1 and the side plate 2, and an auxiliary anchor rod 4 is fixedly connected inside the side plate 2.

[0039] Specifically, when installing the base plate 1 and the side plate 2, the base plate 1 and the side plate 2 are first connected and installed by the support rods, and then the base plate 1 and the side plate 2 are connected to the foundation pit by the positioning anchor rods. During this process, the auxiliary anchor rods 4 are also installed to ensure that the base plate 1 and the side plate 2 stably support the foundation pit.

[0040] The water guide pipe 3 is fixedly connected to the inside of the side plate 2, and a fixing plate 5 is fixedly connected to the inner wall of the water guide pipe 3. The filter plate 12 is connected to the inside of the water guide pipe 3 through the swing assembly. The inner connecting plate 8 is fixedly connected to the inner wall of the water guide pipe 3, and an air bag 15 is bonded to the surface of the inner connecting plate 8. The swing assembly includes a connecting plate 6 fixedly connected to the inner wall of the water guide pipe 3, and a telescopic rod 7 is bolted to the surface of the connecting plate 6. A pressing plate 9 is fixedly connected to the output end of the telescopic rod 7. In addition, the pressing plate 9 is rotatably connected to the long pin 10, and a ball bearing 11 is movably connected to the end of the long pin 10. The water guide pipe 3 is inclined.

[0041] Specifically, during normal operation, water inside the soil enters the water pipe 3 through the guide channel 28 and is discharged through the water pipe 3. After long-term use, when it is necessary to stabilize the bottom plate 1 and the side plate 2, the telescopic rod 7 is activated. During the operation of the telescopic rod 7, it directly pushes the filter plate 12 through the squeezing plate 9, the long pin 10 and the ball bearing 11. The filter plate 12 then swings under the action of thrust and its own gravity, causing impurities to be shaken off. As a result, no impurities remain on the filter plate 12, which can better drain water.

[0042] Example 2: Please refer to Figures 5-7 The long pin 10 is connected to the fixed plate 5 via a reciprocating assembly, and a brush is fixedly connected to the surface of the long pin 10. In addition, when the airbag 15 is working, air is supplied to the long pin 10 through the hose 18. The reciprocating assembly includes a drive motor 13 fixedly connected to the surface of the extrusion plate 9, and the output end of the drive motor 13 is fixedly connected to the long pin 10.

[0043] Specifically, when the telescopic rod 7 is working, since the connecting plate 6 is fixedly connected to the inner wall of the water pipe 3, and the telescopic rod 7 is fixedly connected to the connecting plate 6, the telescopic rod 7 itself remains stable when it is working. The output end of the telescopic rod 7 drives the extrusion plate 9 and the long pin 10 to move. During this process, the drive motor 13 on the surface of the extrusion plate 9 directly drives the long pin 10 to rotate and then turn back. At this time, while the long pin 10 is pushing the filter plate 12 forward, it is also in a rotating state, which drives the brush to directly unclog the inside of the water pipe 3, so that the water flows better.

[0044] Airbags 15 are symmetrically distributed on both sides of the inner plate 8. The surface of the extrusion plate 9 is in contact with the surface of the airbag 15. An air intake pipe 19 is fixedly connected to the upper surface of the airbag 15, and an output pipe 20 is fixedly connected to the side of the airbag 15. In addition, the output pipe 20 is connected to the long pin 10 through a hose 18. The surface of the long pin 10 is also provided with air jets 16 at equal intervals.

[0045] Specifically, during the movement of the extrusion plate 9, it cooperates with the inner plate 8 to directly extrude airbag 15. When airbag 15 is extruded, it supplies air to long pin 10 through output pipe 20 and hose 18. At this time, long pin 10 extrudes air through air nozzle 16. When the telescopic rod 7 moves the extrusion plate 9 back, the extrusion plate 9 does not extrude airbag 15. At this time, airbag 15 inhales air through suction pipe 19, and then airbag 15 inflates, making it convenient for the next use. That is, airbag 15 will intermittently extrude air through air nozzle 16, which plays an auxiliary role in unblocking.

[0046] One-way valves 14 are fixedly connected to the surface of both the intake pipe 19 and the output pipe 20.

[0047] Specifically, when the airbag 15, inhalation pipe 19, jet nozzle 16 and output pipe 20 are working, the one-way valve 14 directs the airflow from the inhalation pipe 19 to the jet nozzle 16, preventing backflow and ensuring the stability of the operation of the airbag 15, inhalation pipe 19, jet nozzle 16 and output pipe 20.

[0048] Example 3: Please refer to Figures 8-10 The side rod 24 is connected to the auxiliary anchor rod 4 via a release assembly; the release assembly includes a connecting rod 17 fixedly connected to the side of the extrusion plate 9, and the end of the connecting rod 17 is fixedly connected to the working plate 21, and a push rod 22 is movably provided on the surface of the working plate 21.

[0049] When the telescopic rod 7 first drives the extrusion plate 9 to work, the extrusion plate 9 will directly drive the working plate 21 and the push rod 22 to work through the connecting rod 17.

[0050] The auxiliary anchor rod 4 has a sliding rod 23 inside, and the end of the sliding rod 23 is hemispherical. Initially, the end of the sliding rod 23 is in contact with the surface of the push rod 22.

[0051] Specifically, when the connecting rod 17 directly drives the working plate 21 and the push rod 22 to work, the push rod 22 will push the slide rod 23, at which time the slide rod 23 will slide inside the auxiliary anchor rod 4.

[0052] A limiting plate 25 is fixedly connected to the surface of the slide rod 23, and the outer wall of the limiting plate 25 is in contact with the inner wall of the auxiliary anchor rod 4. A connecting shaft 27 is rotatably provided inside the auxiliary anchor rod 4, and a side rod 24 is fixedly connected to the surface of the connecting shaft 27. A side block 26 is fixedly connected to the inner wall of the side rod 24. The side block 26 is hemispherical, and the lower surface of the slide rod 23 is in contact with the surface of the side block 26.

[0053] Specifically, when the sliding rod 23 slides inside the auxiliary anchor rod 4, it will drive the limiting plate 25 to slide synchronously. The limiting plate 25 improves the stability of the sliding rod 23 when it works inside the auxiliary anchor rod 4. At the same time, the sliding rod 23 will directly push the side block 26, which is hemispherical. Then, the side block 26 and the side rod 24 rotate around the connecting shaft 27 inside the auxiliary anchor rod 4. Then, the side rod 24 opens from the inside of the auxiliary anchor rod 4 and directly inserts into the soil layer, which increases the insertion area of ​​the auxiliary anchor rod 4 and helps to stabilize it, making the auxiliary anchor rod 4 more stable when it works and realizing the function of loosening compensation.

[0054] A method for using an auxiliary drainage type foundation pit support component includes the following steps:

[0055] S1. During use, water seeping from the soil layer is discharged through the guide channel 28 and the water pipe 3. After a long period of use, the telescopic rod 7 is activated. At this time, the telescopic rod 7 drives the filter plate 12 to swing through the swing assembly, so that no particles remain on the filter plate 12, and the water is discharged better.

[0056] S2. When the telescopic rod 7 is working, under the action of the reciprocating component, the long pin 10 and the brush work inside the water pipe 3 to reciprocate and efficiently dredge the water pipe 3, so that the water pipe 3 drains more smoothly. At the same time, the airbag 15 is also in working condition. The airbag 15 and the jet nozzle 16 play an auxiliary role in dredging.

[0057] S3. When the telescopic rod 7 is working, the slide rod 23 is directly pushed by the push rod 22, and the slide rod 23 directly pushes the side block 26, causing the side block 26 and the side rod 24 to rotate around the connecting shaft 27. Then the side rod 24 opens from the inside of the auxiliary anchor rod 4 and inserts into the soil layer, which plays the role of auxiliary positioning and loosening compensation, making the auxiliary anchor rod 4 more stable when working.

[0058] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0059] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
