Description

Technical Field

[0001] The present application relates to the technical field of gravel formation ground construction, and in particular to a gravel formation plastic drainage board and booster pipe hole drawing equipment and a construction method. Background Art

[0002] It is an economical and effective method to use drainage boards and booster pipes to drain and consolidate the foundation of soft soil sites. On the other hand, when there is a hard crust layer such as stone fill or soil fill on the surface of the soft soil site, it is often very difficult to install drainage boards.

[0003] To solve this problem, although the method of excavating the surface layer and filling it with stone or soil can be used, this method is not very suitable for thick hard crust layers because it is difficult to excavate, requires high backfill materials, and is expensive. At present, most of them use the method of leading holes, first drilling a hole in the hard crust layer of the foundation surface filled with stone or soil, and then driving the drainage board from the hole to the soft soil layer. Since the hard crust layer filled with stone or soil is easy to collapse, the drainage board often cannot be driven down, affecting the construction.

[0004] With respect to the above-mentioned related technologies, the inventors believe that when the drainage board and the booster pipe are introduced into the stratum through the pre-drilled holes, the holes are prone to collapse, making it impossible to drive the drainage board and the booster pipe down, affecting the construction. Summary of the invention

[0005] The purpose of this application is to provide a gravel formation plastic drainage board and booster pipe hole-guiding equipment and construction method, so as to improve the problem that when the drainage board and the booster pipe are introduced into the formation through the pre-drilled hole, the hole is easy to collapse, making it impossible to drive the drainage board and the booster pipe into the formation and affecting the construction.

[0007] By adopting the above technical scheme, the installation component is fixed under the vibrating hammer of the pile driver, and a guide hole component is arranged under the installation component so that the guide hole component corresponds to the gravel foundation. The guide hole component is driven into the gravel foundation by the vibrating hammer on the pile driver, and a drain board and a boost pipe are placed in the guide hole component. The lighter drain board is clamped and fixed by the guide hole component. After the guide hole component is driven into the foundation, the drain board and the boost pipe are brought into the foundation; after the guide hole component is driven into the gravel foundation for a certain distance, the clamp in the guide hole component loosens the drain board, and the worker cuts the drain board outside the guide hole component. Then the pile driver lifts the vibrating hammer and pulls the guide hole component out of the foundation. During the upward movement of the guide hole component, the bottom of the guide hole component is opened, so that the drain board and the boost pipe in the guide hole component fall into the hole opened in the foundation, and the installation of the drain board and the boost pipe is completed, so as to prevent the drainage board and the boost pipe from not being installed and affecting the construction.

[0009] By adopting the above technical scheme, the mounting seat is connected and fixed to the vibrating hammer through a connecting piece, so that the side of the mounting seat close to the vibrating hammer is against the vibrating hammer, and the mounting seat is prevented from shaking under the vibrating hammer when the vibrating hammer is working. When the guide hole assembly is drilled, the mounting seat is offset, which may damage the guide hole assembly. By opening a mounting groove on the side of the mounting seat away from the vibrating hammer and detachably connecting it to the guide hole assembly, the mounting seat can replace the guide hole assembly when the guide hole assembly is damaged. Optionally, the guide hole assembly includes a hollow connecting tube, a connecting hole is formed at one end of the connecting tube close to the mounting seat, the connecting hole passes through the side wall of the mounting groove on the mounting seat, a connecting rod is provided in the connecting hole to fix the connecting tube in the mounting groove, the inner side wall of the connecting tube is connected to the clamping assembly, the clamping assembly fixes the drain board in the connecting tube so that the drain board is arranged along the length direction of the connecting tube, a connecting groove corresponding to the drain board is formed on the side wall of the connecting tube, and the end of the connecting tube away from the mounting seat is rotatably connected to the opening assembly.

[0010] By adopting the above technical scheme, one end of the connecting pipe is set in the installation groove of the mounting seat and abutted against the inner wall of the installation groove. The connecting rod is passed through the connecting pipe and the connecting hole opened in the side wall of the installation groove to fix the connecting pipe in the installation groove. The connecting pipe can be replaced, and the drain board is introduced into the connecting pipe through the connecting groove opened in the side wall of the connecting pipe, so that the drain board is arranged along the length direction of the connecting pipe, and the drain board is fixed by the clamping assembly arranged in the connecting pipe. The hole wall opened in the formation is supported by the connecting pipe. After the connecting pipe is driven into the gravel formation, the clamping assembly releases the fixation of the drain board. In the process of the pile driver moving the connecting pipe upward, the opening assembly under the connecting pipe is opened to leave the drain board in the formation, thereby completing the setting of the drain board.

[0011] Optionally, the clamping assembly includes a clamping member in contact with the drain board, a support frame fixed to the inner wall of the connecting pipe is provided on the side of the clamping member away from the drain board, a driving member 1 is provided on the support frame, a driving rod of the driving member 1 is connected to the clamping member, and the supporting member is arc-shaped on the side close to the drain board.

[0012] By adopting the above technical scheme, a driving member arranged on the support frame drives the clamping member to approach the drain board, and the drain board is fixed between the inner wall of the connecting pipe and the clamping member, so that the drain board can move as the vibrating hammer drives the connecting pipe into the formation, and the influence of the inconsistent depth of the drain board in the formation on the subsequent construction of the formation is minimized. After the connecting pipe is driven for a certain distance, the clamping member loosens the drain board, and the worker cuts the drain board outside the connecting groove of the connecting pipe. During the process of moving the connecting pipe upward, the drain board is left in the lead hole, leaving only a part exposed on the ground, and the connection of the connecting pipe to the hole wall formation The support of the drainage board is completed.

[0013] Optionally, a support block is provided in the connecting pipe on a side of the drain board away from the clamping member, the support block is in contact with the drain board, and an attachment is provided between the support block and the side wall of the supporting member, the attachment is in contact with the side wall of the drain board.

[0014] By adopting the above technical solution, a support block is set on the inner wall of the connecting pipe, and the clamping piece is close to the drain board to fix the drain board between the clamping piece and the support block, thereby reducing the contact between the drain board and the side wall of the connecting pipe as much as possible, so that the contact between the drain board and the side wall of the connecting pipe reduces the possibility of the drain board being adsorbed on the smooth inner wall of the connecting pipe; attachments are set on the side walls of the support block and the clamping piece to protect the side walls of the drain board, thereby reducing the wear of the side walls of the drain board by the clamping piece and the support block.

[0015] Optionally, a hollow fixed tube is provided on the inner side wall of the connecting tube, the fixed tube is provided along the length direction of the connecting tube, the fixed tube corresponds to the clamping assembly, a boosting tube is placed in the fixed tube, a connecting groove 2 corresponding to the boosting tube is opened on the side wall of the fixed tube, and the connecting groove 2 is communicated with the connecting groove 1 opened on the side wall of the connecting groove.

[0016] By adopting the above technical scheme, the fixed pipe is arranged on the inner wall of the connecting pipe, which plays a certain supporting role on the side wall of the connecting pipe. When the vibrating hammer hammers the connecting pipe downward, the fixed pipe in the connecting pipe moves into the formation together, and the connecting pipe and the connecting pipe. The connecting grooves on the fixed pipe are left on the ground, and the boosting pipe is introduced into the fixed pipe through the connecting groove 2 on the side wall of the fixed pipe. As the connecting pipe is lifted, the boosting pipe moves away from the fixed pipe, so that the boosting pipe is gradually exposed in the holes in the formation, and only a small part of the boosting pipe is left on the ground, thereby completing the installation of the boosting pipe.

[0017] Optionally, the hole-opening assembly includes an hole-opening member, which is rotatably arranged at one end of the connecting pipe away from the mounting seat, the side of the hole-opening member away from the connecting pipe is conical, and the side of the hole-opening member close to the connecting pipe is in contact with the drain plate in the connecting pipe and the boost pipe in the fixed pipe.

[0018] By adopting the above technical scheme, the hole-opening piece is rotatably set at the end of the connecting pipe away from the mounting seat, and the conical side of the hole-opening piece is in contact with the ground. When the vibratory hammer is working, the connecting pipe drills a hole in the gravel formation through the hole-opening piece, so that the connecting pipe is inserted into the formation. When the vibratory hammer drives the connecting pipe into the formation, the hole-opening piece closes the pipe mouth of the connecting pipe to prevent the connecting pipe and the fixed pipe from entering the soil. When the pile driver lifts the connecting pipe from the formation, the hole-opening piece rotates in the direction away from the pipe mouth of the connecting pipe under the action of its own gravity, opens the pipe mouth of the connecting pipe, and allows the drainage plate and the booster pipe to fall into the formation.

[0019] Optionally, a sensor for detecting the position of the drain plate is provided at one end of the connecting pipe close to the opening member, and the sensor is electrically connected to the driving member. A fixing plate in contact with the side wall of the fixed pipe is provided in the connecting pipe, and the fixing plate is provided along the length direction of the connecting pipe and in contact with the opening member.

[0020] By adopting the above technical solution, after the drain board passes through the sensor at the pipe opening of the connecting pipe, the sensor starts the driving component 1 to clamp the drain board to ensure that the degree to which the drain board is left in the formation is relatively consistent. A fixed plate is set on the inner wall of the connecting pipe to support the connecting pipe and reduce the possibility of bending of the connecting pipe. At the same time, the drain board and the fixed pipe are separated to prevent the drain board from being stuck in the gap between the connecting pipe and the fixed pipe.

[0021] A construction method for a plastic drainage board and a booster pipe lead hole in a gravel formation, comprising the following steps: Connect the mounting base to the connecting pipe, fix the mounting base under the vibrating hammer of the pile driver, and drive the connecting pipe into the ground through the vibrating hammer; After the connecting pipe is driven into the gravel formation for a certain distance, the drainage plate and the booster pipe are introduced into the gravel formation through the connecting pipe and the fixed pipe arranged in the connecting pipe; The pile driver then lifts the mounting base together with the connecting pipe, so that the opening under the connecting pipe opens due to its own gravity, leaving the drainage board and the booster pipe in the gravel formation.

[0022] Optionally, the construction method of the drainage board and the booster pipe lead hole includes the following steps: Place one end of the connecting pipe in the mounting groove of the mounting seat, pass the connecting rod through the connecting pipe and the connecting hole on the side wall of the mounting groove to fix the connecting pipe, introduce the drain plate into the connecting pipe through the connecting groove 1 on the connecting pipe, and after the drain plate passes the sensor along the length direction of the connecting pipe, the driving member 1 drives the clamping member to approach the drain plate, and fix the drain plate between the clamping member and the supporting block on the side wall of the connecting pipe; Connect the vibrating hammer to the connection groove on the mounting base, fix the mounting base on the vibrating hammer with a connecting piece, make the connecting pipe vertical to the ground, and make the opening piece rotated under the connecting pipe to close the pipe opening of the connecting pipe, so that the opening piece contacts the ground; Then, the vibrating hammer is started to drive the connecting pipe into the gravel layer through the opening member, so that the connecting pipe enters the layer for a certain distance, and the connecting grooves opened on the connecting pipe and the fixed pipe are located above the ground; The boost pipe is sent into the inner wall of the fixed pipe through the connecting groove 2 opened on the fixed pipe, so that the bottom of the boost pipe contacts the opening part. After the worker cuts the drain board, the driving part drives the clamping part to loosen the drain board, so that the drain board contacts the opening part.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. Set one end of the connecting pipe in the mounting groove of the mounting seat so that it abuts against the inner side wall of the mounting groove. Use a connecting rod to pass through the connecting pipe and the connecting hole opened in the side wall of the mounting groove to fix the connecting pipe in the mounting groove. The connecting pipe can be replaced. The drain board is introduced into the connecting pipe through the connecting groove opened in the side wall of the connecting pipe, so that the drain board is set along the length direction of the connecting pipe. The drain board is fixed by the clamping assembly set in the connecting pipe. After the connecting pipe is driven into the gravel formation, the clamping assembly releases the fixation of the drain board. When the pile driver moves the connecting pipe upward, the opening assembly under the connecting pipe is opened to leave the drain board in the formation, and the setting of the drain board is completed. 2. Use a driving member arranged on the support frame to drive the clamping member close to the drain board, fix the drain board between the inner wall of the connecting pipe and the clamping member, so that the drain board can move as the vibrating hammer drives the connecting pipe into the stratum, and minimize the influence of the inconsistent depth of the drain board in the stratum on the subsequent construction of the stratum. After the connecting pipe is driven for a certain distance, the clamping member releases the drain board, and the worker cuts off the drain board outside the connecting groove of the connecting pipe. In the process of moving the connecting pipe upward, the drain board is left in the lead hole, leaving only a part exposed on the ground, and the connection pipe supports the hole wall stratum to complete the driving of the drain board; 3. The hole-opening piece is rotated and set at the end of the connecting pipe away from the mounting seat, and the conical side of the hole-opening piece is in contact with the ground. When the vibratory hammer is working, the connecting pipe is punched into the gravel formation through the hole-opening piece to make a hole in the stratum, so that the connecting pipe is inserted into the stratum. When the vibratory hammer drives the connecting pipe into the stratum, the hole-opening piece closes the pipe mouth of the connecting pipe to prevent the connecting pipe and the fixed pipe from entering the soil. When the pile driver lifts the connecting pipe from the stratum, the hole-opening piece rotates in the direction away from the pipe mouth of the connecting pipe under the action of its own gravity, opens the pipe mouth of the connecting pipe, and allows the drain plate and the booster pipe to fall into the stratum.
