Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a prestressed pipe pile double static pressure construction device. Background Technology

[0002] Double static pressure pipe piles are a new pile driving technology. The pile body material is high-strength prestressed concrete pipe piles. The construction process involves first applying normal static pressure, and then using a double static pressure pile driver to apply static pressure at both the top and bottom of the pile to press the pipe pile into the soil. Double static pressure pipe piles have advantages such as high pile body strength, strong penetration ability, low cost, and small settlement. However, the existing double static pressure construction devices for prestressed pipe piles still have shortcomings. Specifically, the existing construction devices cannot prevent the pipe pile from tilting during the pressing process, resulting in poor installation accuracy.

[0003] Therefore, a prestressed pipe pile dual static pressure construction device is needed to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a prestressed pipe pile double static pressure construction device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A prestressed pipe pile double static pressure construction device includes a construction seat, a limit mechanism is provided inside the construction seat, a controller is installed on the outer wall of the construction seat, a terminal block is installed on the top of the construction seat, and anchor bolts are installed inside the construction seat.

[0007] The limiting mechanism includes a fixed sleeve fixedly connected inside the construction seat. A piston plate is slidably connected inside the fixed sleeve. A sliding rod is fixedly connected to the outer wall of the piston plate inside the fixed sleeve. A limiting block is fixedly connected to the outer wall of the sliding rod at the end away from the piston plate. A return spring is fixedly connected to the outer wall of the piston plate near the sliding rod. A displacement sensor is fixedly connected inside the sliding rod. A guide tube is fixedly connected to the inside of the fixed sleeve near the piston plate. A connecting pipe is fixedly connected to the outer wall of the guide tube near the inside of the fixed sleeve. An inlet pipe is fixedly connected to the outer wall of the connecting pipe. A solenoid valve is fixedly connected to the inside of the guide tube.

[0008] As a preferred embodiment of this utility model, the construction base is made of stainless steel, and the controller is connected to the terminal block by electrical connection.

[0009] As a preferred embodiment of this utility model, the fixed sleeve, sliding rod and limiting block are all made of stainless steel, the limiting block has a hemispherical structure design, and the reset spring is fixedly connected to the fixed sleeve.

[0010] As a preferred embodiment of this utility model, multiple sets of the fixed sleeve, piston plate, sliding rod, limiting block and guide tube are provided, and the connecting tube is a ring structure design.

[0011] As a preferred embodiment of this utility model, the liquid inlet pipe passes through and extends to the outside of the construction seat, the connecting pipe has an L-shaped structure design, and the sliding rod passes through the fixing sleeve and extends to the outside of the construction seat.

[0012] In a preferred embodiment of this invention, the displacement sensor, solenoid valve, and controller are all electrically connected.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, a prestressed pipe pile double static pressure construction device is designed. The limiting mechanism in the device is used to prevent the pipe pile from tilting. The construction seat is placed at the foundation pit location and fixed to the ground with anchor bolts. The controller opens the solenoid valve, and the inlet pipe is connected to the hydraulic oil pump through the conduit. The hydraulic oil pump sends hydraulic oil into the guide pipe through the inlet pipe and the connecting pipe. The hydraulic oil in the guide pipe flows into the fixed sleeve and pushes the piston plate in the fixed sleeve to move outward. The piston plate drives the limiting block to move outward through the sliding rod. The displacement sensor detects the distance of the limiting block. When the limiting block moves to the appropriate position, the controller closes the solenoid valve, and the limiting block stops moving. The pipe pile is placed in the foundation pit for double static pressure construction. The limiting block will hold the pipe pile in place to prevent it from tilting. This solves the problem that existing construction devices cannot prevent the pipe pile from tilting during the pressing process, resulting in poor installation accuracy. Attached Figure Description

[0025] The construction base 1 is made of stainless steel, and the controller 3 is connected to the terminal block 4 by electrical connection.

[0026] In this embodiment, reference Figure 2 and Figure 3 The limiting mechanism 2 includes a fixed sleeve 201 fixedly connected inside the construction seat 1. A piston plate 202 is slidably connected inside the fixed sleeve 201. A sliding rod 203 is fixedly connected to the outer wall of the piston plate 202 inside the fixed sleeve 201. A limiting block 204 is fixedly connected to the outer wall of the sliding rod 203 at the end away from the piston plate 202. A return spring 205 is fixedly connected to the outer wall of the piston plate 202 near the sliding rod 203. A displacement sensor 206 is fixedly connected inside the sliding rod 203. A guide tube 207 is fixedly connected to the inside of the fixed sleeve 201 near the piston plate 202.

An inlet tube 209 is fixedly connected to the outer wall of the connecting tube 208. A solenoid valve 210 is fixedly connected inside the guide tube 207.

[0027] The fixed sleeve 201, sliding rod 203, and limiting block 204 are all made of stainless steel. The limiting block 204 has a hemispherical structure design. The return spring 205 is fixedly connected to the fixed sleeve 201. Multiple sets of the fixed sleeve 201, piston plate 202, sliding rod 203, limiting block 204, and guide pipe 207 are provided. The connecting pipe 208 has a ring structure design. The liquid inlet pipe 209 passes through and extends to the outside of the construction seat 1.

The outer diameter of the pipe pile is input into the controller 3. The controller 3 calculates the moving distance of the limit block 204 based on the input data. The controller 3 opens the solenoid valve 210. The inlet pipe 209 is connected to the hydraulic oil pump using a conduit. The hydraulic oil pump sends hydraulic oil into the guide pipe 207 through the inlet pipe 209 and the connecting pipe 208. Inside, the hydraulic oil in the guide pipe 207 flows into the fixed sleeve 201 and pushes the piston plate 202 inside the fixed sleeve 201 to move outward. The piston plate 202 drives the limit block 204 to move outward through the sliding rod 203. The displacement sensor 206 detects the moving distance of the limit block 204. When the limit block 204 moves to the appropriate position, the controller 3 closes the solenoid valve 210, and the limit block 204 stops moving. The pipe pile is then placed into the foundation pit for double static pressure construction. The limit block 204 will hold the pipe pile in place to prevent it from tilting.
