A pile foundation pit enclosure device

Abstract

This invention relates to the field of pile foundation pit enclosure equipment, and more particularly to a pile foundation pit enclosure device. Current methods of enclosing pile foundation pits suffer from problems such as easy loosening under impact and poor sealing. A pile foundation pit enclosure device includes baffles; the bottom of the baffle has two disassembly openings, the baffle itself has two guide grooves, and the top of the baffle is rotatably connected to two guide wheels. Workers fix one baffle to the upper part of the pile foundation pit wall using screws, then insert the two guide wheels from the other baffle into the two guide grooves on the first baffle, repeating this process to assemble multiple baffles. The multiple baffles collectively provide support and reinforcement to the pile foundation pit wall, making the soil around the pile foundation pit more stable and thus improving the safety of the working environment inside the pile foundation pit.

Description

Technical Field

[0001] This invention relates to the field of pile foundation pit enclosure equipment, and more particularly to a pile foundation pit enclosure device. Background Technology

[0002] Pit enclosure is a set of measures to support, reinforce and protect the sidewalls and surrounding environment of the pit in order to ensure the safety of underground structure construction and the surrounding environment. Pit support engineering is a temporary project, and the safety reserve can be relatively small, but it is also related to the region, as the geological conditions of different regions are also different.

[0003] However, most current methods of enclosing pile foundation pits involve using multiple channel steel plates to form walls to enclose the pit walls. However, the adjacent channel steel plates are mostly interlocked, which limits their ability to withstand impact. When soil falls from the pit walls, the channel steel plates are easily loosened by the impact. Furthermore, the sealing between adjacent channel steel plates is poor, allowing groundwater to carry soil into the pile foundation pit through the gaps between the adjacent channel steel plates, resulting in an inadequate enclosure effect for the pile foundation pit. Summary of the Invention

[0004] In view of the shortcomings or deficiencies of the prior art, the present invention provides a pile foundation pit enclosure device that can make the connection between adjacent baffles more stable, thereby effectively preventing the soil from falling off the pit wall and squeezing the baffles to loosen, and also improving the sealing between adjacent baffles, resulting in a better enclosure effect for the pile foundation pit.

[0005] A pile foundation pit enclosure device includes a baffle plate with two disassembly openings at the bottom and two guide grooves. Two guide wheels are rotatably connected to the top of the baffle plate. Two countersunk nuts are fixedly connected to both sides of the upper part of the baffle plate. A cover plate is placed on the baffle plate. A blocking mechanism is provided on the guide grooves to support and block the soil of the pit wall. A limiting mechanism is provided on the baffle plate to further limit the position of the baffle plate.

[0006] More preferably, the blocking mechanism includes a blocking frame, with the blocking frame slidably connected to the lower part of both guide grooves. The two blocking frames are symmetrically arranged and are located above the two disassembly ports on the baffle. A return spring is connected between the baffle and the two blocking frames. A nail post is fixedly connected to each of the two blocking frames, and the two nail posts pass through the baffle.

[0007] More preferably, the limiting mechanism includes a limiting plate, the baffle has an opening, the limiting plate is slidably connected to the opening, the limiting plate is slidably connected to the baffle, and the top of the baffle has a limiting slot.

[0008] More preferably, the limiting plate is provided with a pull opening, and the pull opening on the limiting plate is provided with anti-slip texture.

[0009] More preferably, it also includes a locking mechanism, which is disposed on the limiting plate. The locking mechanism includes a guide frame. The lower part of the limiting plate has two grooves. The upper part of the inner wall of the baffle is fixedly connected to two guide frames, which are symmetrically arranged. Each guide frame is slidably connected to a locking frame. The lower part of each locking frame is fixedly connected to a roller. The top of the limiting plate is bolted to two inclined slot frames, which are symmetrically arranged.

[0010] More preferably, both of the inclined slot frames are provided with guide slots, and the two rollers are respectively located in the guide slots on the two inclined slot frames.

[0011] More preferably, it also includes a sealing mechanism disposed on the baffle. The sealing mechanism includes a square cylinder body, which is bolted to the upper part of the inner wall of the baffle. Piston rods are fixedly connected to both locking brackets. The square cylinder body and the two piston rods are slidably connected. A connecting pipe is fixedly connected to the top of the square cylinder body, and the connecting pipe communicates with the square cylinder body. A rubber tube is fixedly connected to the baffle, and the rubber tube is fixedly connected to the connecting pipe, and the rubber tube communicates with the connecting pipe.

[0012] More preferably, the rubber tube is made of rubber.

[0013] More preferably, it also includes a dustproof mechanism, which is disposed on the baffle. The dustproof mechanism includes a mounting base, and two mounting bases are fixedly connected to the top of the baffle. A dustproof cover is rotatably connected between the two mounting bases. The dustproof cover is located below the limiting slot, and a torsion spring is connected between the dustproof cover and the two mounting bases.

[0014] The beneficial effects of this invention are as follows: First, the worker fixes one of the baffles to the upper part of the pit wall of the pile foundation pit using screws. Then, the worker inserts two guide wheels from the other baffle into the two guide grooves on the first baffle. Next, the other baffle moves downward under the action of gravity. Then, two nails on the first baffle insert into the pit wall of the pile foundation pit. Finally, the worker pulls the limiting plate on one baffle downward, and the limiting plate on one baffle engages with the limiting slot on the other baffle. The limiting plate on one baffle limits the other baffle. This process is repeated to assemble multiple baffles. By having multiple baffles work together to block and support the pit wall of the pile foundation pit, the soil around the pile foundation pit can be made more stable, thereby making the working environment inside the pile foundation pit safer.

[0015] Secondly, when the staff pulls the limiting plate on the other baffle downwards, the two locking frames on the other baffle will work together to limit the limiting plate on one of the baffles, making the connection between adjacent baffles more stable. This can effectively prevent the soil on the pit wall from falling off and squeezing the baffles to loosen, and further improve the safety of the working environment inside the pile foundation pit.

[0016] In addition, when the two inclined slot frames squeeze the two locking frames and move them closer to each other, the two piston rods will jointly push the air in the square cylinder into the rubber tube through the connecting pipe, causing the rubber tube to inflate and expand. This improves the sealing between adjacent baffles, thereby preventing groundwater from seeping in and carrying soil into the pile foundation pit, resulting in a better enclosure effect for the pile foundation pit.

Detailed Implementation

[0031] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, welding, and bonding that are mature in the prior art, and will not be described in detail here.

[0032] Example 1: A pile foundation pit enclosure device, such as Figures 1-13 As shown, the device includes a baffle 1 with two disassembly openings at the bottom and two guide grooves 2 on its surface. Two guide wheels 3 are rotatably connected to the top of the baffle 1. Two countersunk nuts 4 are bolted to both sides of the upper part of the baffle 1. The countersunk nuts 4 are used to assist the screw in fixing the baffle 1. A cover plate 5 is placed on the baffle 1. A blocking mechanism is provided on the guide grooves 2 to support and block the soil on the pit wall. A limiting mechanism is provided on the baffle 1 to further limit the position of the baffle 1.

[0033] The blocking mechanism includes a blocking frame 61. The blocking frame 61 is slidably connected to the lower part of the two guide grooves 2. The two blocking frames 61 are symmetrically arranged and are located above the two disassembly ports on the baffle 1. The baffle 1 and the two blocking frames 61 are connected by a return spring 62 through a hook. The two blocking frames 61 are welded with nail posts 63, and the two nail posts 63 pass through the baffle 1. The top post 63 is used to limit the position of the baffle 1.

[0034] The limiting mechanism includes a limiting plate 72. The baffle 1 has an opening 71, and the limiting plate 72 is slidably connected to the opening 71. The limiting plate 72 is used to connect and fix adjacent baffles 1. The limiting plate 72 is slidably connected to the baffle 1. The top of the baffle 1 has a limiting slot 73.

[0035] Initially, the two blocking brackets 61 block the two disassembly ports on the baffle 1. First, the workers fix one of the baffles 1 to the upper part of the pit wall of the pile foundation pit with screws. Then, the workers insert the two guide wheels 3 on the other baffle 1 into the two guide grooves 2 on the other baffle 1. Next, the workers release the other baffle 1, and the other baffle 1 and the two guide wheels 3 on the other baffle 1 will move downward along the two guide grooves 2 on the other baffle 1 under the action of gravity. When the other baffle 1 and the two guide wheels 3 on the other baffle 1 move downward to the bottom of the other baffle 1, the other baffle 1 will swing downward under the action of gravity. Then, the other baffle 1 and the two guide wheels 3 on the other baffle 1 will move diagonally downward under the action of gravity. The two guide wheels 3 on the other baffle 1 will contact the two blocking brackets 61 on the other baffle 1 respectively, and the two guide wheels 3 on the other baffle 1 will push one of the two guide wheels 61 on the other baffle 1 respectively. The two blocking brackets 61 on one of the baffles 1 move diagonally downwards, compressing the four return springs 62 on one of the baffles 1. The two blocking brackets 61 on one of the baffles 1 no longer block the two disassembly ports on that baffle 1. The diagonal downward movement of the two blocking brackets 61 on one of the baffles 1 will then cause the two nail posts 63 on that baffle 1 to move diagonally downwards, inserting them into the wall of the pile foundation pit. Finally, the worker pulls the limiting plate 72 on one of the baffles 1 downwards, causing it to engage with the limiting slot 73 on the other baffle 1. The limiting plate 72 on one baffle 1 then limits the other baffle 1. This process is repeated to assemble multiple baffles 1. By using multiple baffles 1 together to block and support the walls of the pile foundation pit, the soil around the pit becomes more stable, thus improving the safety of the working environment within the pile foundation pit.

[0036] When the pile foundation pit construction is completed and workers dismantle the other baffle 1, they will pull the limiting plate 72 on one of the baffles 1 upwards to reset it. The limiting plate 72 on one baffle 1 will then disengage from the other baffle 1. Workers will then pull the other baffle 1, along with its two guide wheels 3, two nail posts 63, and two blocking frames 61, to move diagonally upwards. The two nail posts 63 on the other baffle 1 will then disengage from the pit wall, and the two return springs 62 on the other baffle 1 will reset. The reset of the two return springs 62 on the other baffle 1 will then drive the other baffle 1... The two blocking brackets 61 move upwards and reset, and the two blocking brackets 61 on the other baffle 1 will respectively block the two disassembly ports on the other baffle 1. The reset of the two blocking brackets 61 on the other baffle 1 will respectively drive the two nail posts 63 on the other baffle 1 to move upwards and reset. When the two guide wheels 3 on the other baffle 1 move above the two disassembly ports on one of the baffle 1, the other baffle 1 and the two guide wheels 3 on the other baffle 1 will move downwards under the action of gravity. One of the baffle 1 will disengage from the two guide wheels 3 on the other baffle 1, thereby completing the disassembly of the other baffle 1.

[0037] Example 2: Based on Example 1, such as Figures 6-11 As shown, it also includes a locking mechanism, which is disposed on the limiting plate 72. The locking mechanism includes a guide frame 82. The lower part of the limiting plate 72 has two grooves 81. The upper part of the inner wall of the baffle 1 is connected to the two guide frames 82 by bolts. The two guide frames 82 are symmetrically arranged. Locking frames 83 are slidably connected to each of the two guide frames 82. The guide frames 82 are used to guide the locking frames 83. The two locking frames 83 are used to limit the limiting plate 72. Rollers 84 are welded to the lower part of each of the two locking frames 83. The top of the limiting plate 72 is connected to two inclined slot frames 85 by bolts. The two inclined slot frames 85 are symmetrically arranged. Each of the two inclined slot frames 85 has a guide inclined slot. The two rollers 84 are respectively located in the guide inclined slots on the two inclined slot frames 85.

[0038] When the worker pulls the limiting plate 72 on the other baffle 1 downwards, the limiting plate 72 on the other baffle 1 will cause the two inclined slot frames 85 on the other baffle 1 to move downwards. The downward movement of the two inclined slot frames 85 on the other baffle 1 will respectively squeeze the two locking frames 83 on the other baffle 1 and move them closer to each other. The two locking frames 83 on the other baffle 1 will then engage with the two limiting slots 73 of the limiting plate 72 on one of the baffle 1. The two locking frames 83 on the other baffle 1 will work together to limit the limiting plate 72 on one of the baffle 1, making the connection between adjacent baffles 1 more stable, thereby effectively preventing the pit wall from being blocked. When soil erosion causes baffle 1 to loosen, the safety of the working environment inside the pile foundation pit is further improved. When the worker pulls the limiting plate 72 on the other baffle 1 to move upward and reset, the limiting plate 72 on the other baffle 1 will drive the two inclined slot frames 85 on the other baffle 1 to move upward and reset. The reset of the inclined slot frames 85 on the other baffle 1 will respectively squeeze the two locking frames 83 on the other baffle 1 to move away from each other and reset. The limiting plate 72 on one of the baffle 1 will disengage from the two locking frames 83 on the other baffle 1, and the two locking frames 83 on the other baffle 1 will no longer limit the limiting plate 72 on one of the baffle 1.

[0039] Example 3: Based on Example 2, such as Figures 2-11 As shown, it also includes a sealing mechanism, which is disposed on the baffle 1. The sealing mechanism includes a square cylinder 91, which is bolted to the upper part of the inner wall of the baffle 1. Piston rods 92 are welded to both locking brackets 83. The square cylinder 91 and the two piston rods 92 are slidably connected. A connecting pipe 93 is connected to the top of the square cylinder 91 through a flange. The connecting pipe 93 communicates with the square cylinder 91. A rubber tube 94 is fixedly connected to the baffle 1. The rubber tube 94 is made of rubber and is fixedly connected to the connecting pipe 93. The rubber tube 94 communicates with the connecting pipe 93.

[0040] When the two inclined slot frames 85 press the two locking frames 83 to move closer to each other, the two locking frames 83 will drive the two piston rods 92 to move closer to each other. The two piston rods 92 will jointly push the air in the square cylinder 91 through the connecting pipe 93 into the rubber tube 94, causing the rubber tube 94 to inflate and expand. This improves the sealing between adjacent baffles 1, thereby preventing groundwater from seeping in and carrying soil into the pile foundation pit, resulting in better containment of the pile foundation pit. When the two inclined slot frames 85 press the two locking frames 83 to move away from each other and reset, the two locking frames 83 will drive the two piston rods 92 to move closer to each other and reset. The air in the rubber tube 94 will return to the square cylinder 91 under pressure through the connecting pipe 93, and the rubber tube 94 will rebound.

[0041] Example 4: Based on Example 3, such as Figure 7 As shown, it also includes a dustproof mechanism, which is disposed on the baffle 1. The dustproof mechanism includes a mounting base 101. Two mounting bases 101 are welded to the top of the baffle 1. A dustproof cover 102 is rotatably connected between the two mounting bases 101. The dustproof cover 102 is used to block the limiting buckle 73. The dustproof cover 102 is located below the limiting buckle 73. A torsion spring 103 is connected to the dustproof cover 102 and the two mounting bases 101 through a hook.

[0042] Initially, the dust cover 102 blocks the limiting slot 73. When the worker pulls the limiting plate 72 on one of the baffles 1 downwards, the limiting plate 72 on one of the baffles 1 will contact the dust cover 102 on the other baffle 1. The limiting plate 72 on one of the baffles 1 will push the dust cover 102 on the other baffle 1 to swing downwards, and the torsion spring 103 on the other baffle 1 will be torsion. When the worker pulls the limiting plate 72 on one of the baffles 1 upwards to reset, the limiting plate 72 on one of the baffles 1 will disengage from the dust cover 102 on the other baffle 1, and the torsion spring 103 on the other baffle 1 will reset. The reset of the torsion spring 103 on the other baffle 1 will cause the dust cover 102 on the other baffle 1 to swing upwards to reset. In this way, the mud can be blocked, preventing the mud from blocking the limiting slot 73.
