Description

Technical Field

[0001] The present application relates to the field of steel sheet pile driving, and in particular to a steel sheet pile driving construction device for highly sensitive land sites. Background Art

[0002] With the development of economy, various types of pipe network reconstruction projects in municipal engineering are gradually increasing, and they are often constructed near buildings. Under the terrain conditions of severe liquefaction of highly sensitive soil, steel sheet pile sinking operations are very likely to cause deformation of nearby buildings and structures, artificially forming safety hazards or accidents. Steel sheet pile sinking construction devices are mainly used to drive steel sheet piles into the ground to form a continuous plate wall structure, which is commonly used in cofferdams, supports, anti-seepage walls and other projects.

[0003] Existing steel sheet pile driving usually uses a vibrating hammer or a static pressure pile driver for steel sheet pile driving construction. The vibrating hammer is not suitable for steel sheet pile driving construction in highly sensitive land sites. The static pressure pile driver uses a fixing clamp to clamp and fix the top of four implanted steel sheet piles, thereby providing a reaction force for pile driving.

[0004] The above-mentioned prior art solutions have the following defects: the soil of the highly sensitive land site is prone to liquefaction and settlement, and the four implanted steel sheet piles cannot provide sufficient reaction force for the static pressure pile driver, and are prone to tilt, making them inconvenient to use. Utility Model Content

[0005] In order to solve the problems raised in the above background technology, the present application provides a steel sheet pile driving construction device for highly sensitive land sites.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A steel sheet pile driving construction device for a highly sensitive land site comprises a static pressure pile driver, counter-pressure seats are arranged on both sides of the static pressure pile driver, the static pressure pile driver comprises a sliding seat, the counter-pressure seat comprises a mounting seat and a counterweight plate, the side surface of the mounting seat is fixedly connected to the side surface of the sliding seat, a linear motor is fixedly mounted on one side of the counterweight plate, second hydraulic rods are fixedly mounted at both ends of the top of the linear motor, the output end of the second hydraulic rod is fixedly connected to the bottom of the mounting seat, a movable plate is arranged at the bottom of the counterweight plate, two slide rails are fixedly mounted on the top of the movable plate, the output end of the linear motor is slidably connected to one slide rail, and a baffle is arranged on the outer side of the top of the counterweight plate.

[0008] By adopting the above scheme, the side of the mounting seat is fixedly connected with the side of the sliding seat, so that the counter-pressure seat can be fixedly installed on both sides of the static pressure pile driver, and the counterweight block can be placed on the counterweight plate to provide sufficient counterforce for the steel sheet pile sinking, and the stability of the device can be improved to avoid skewing. A second hydraulic rod is fixedly installed at both ends of the top of the linear motor, and the output end of the second hydraulic rod is fixedly connected to the bottom of the mounting seat, so that the second hydraulic rod can work to lift the moving plate from the ground, thereby facilitating the self-propelled device. The output end of the linear motor is slidably connected to a slide rail, so that before the static pressure pile driver can self-propel, the second hydraulic rod can be operated. When the moving plate is lifted, the linear motor works to drive the moving plate forward. After the moving plate moves, the second hydraulic rod works to drive the moving plate downward, so that the moving plate provides support for the device, thereby facilitating the self-propelled static pressure pile driver.

[0011] Furthermore, two guide holes are provided in the middle of the mounting seat, guide rods are slidably connected inside the guide holes, and the bottom of the guide rods is fixedly connected to the linear motor.

[0012] By adopting the above scheme, a guide rod is slidably connected inside the guide hole, and the bottom of the guide rod is fixedly connected to the linear motor, which is convenient for guiding the up and down movement of the linear motor and improving the stability of the up and down movement of the linear motor.

[0013] Furthermore, the top of the sliding seat is slidably connected to the machine head, and the bottom of the sliding seat is slidably connected to four fixing clips.

[0015] Furthermore, two lifting seats are fixedly installed at the bottom of one end of the machine head, and a first hydraulic rod is fixedly installed on the top of the lifting seats.

[0016] By adopting the above solution, the first hydraulic rod is fixedly installed on the top of the lifting seat, which facilitates the fixed installation of the first hydraulic rod.

[0017] Furthermore, a lifting sleeve is sleeved on the outer side of the first hydraulic rod, and the output end of the first hydraulic rod is fixedly connected to the lifting sleeve.

[0018] By adopting the above scheme, a lifting sleeve is provided on the outer side of the first hydraulic rod, and the output end of the first hydraulic rod is fixedly connected to the lifting sleeve, so that the first hydraulic rod can drive the lifting sleeve to move up and down, and the lifting sleeve provides protection for the first hydraulic rod.

[0019] Furthermore, a connecting seat is fixedly installed on the outer sides of the bottom ends of the two lifting sleeves, and a rotating seat is fixedly installed on one side of the connecting seat.

[0020] By adopting the above solution, a connecting seat is fixedly installed on the outer sides of the bottom ends of the two lifting sleeves, and a rotating seat is fixedly installed on one side of the connecting seat, so that the lifting and lowering of the lifting sleeves drives the rotating seat to lift and lower.

[0021] Furthermore, a chuck is inserted into the middle of the rotating seat, and the output end of the rotating seat is fixedly connected to the chuck.

[0022] By adopting the above scheme, the output end of the rotating seat is fixedly connected with the chuck, which makes it convenient for the chuck to clamp and fix the steel sheet pile, and facilitates the static pressure pile driver to carry out the construction of steel sheet pile sinking. The rotating seat is convenient for adjusting the angle of the chuck.

[0023] In summary, the present application has the following technical effects: by fixedly connecting the side of the mounting seat with the side of the sliding seat, it is convenient to fix the counter-pressure seat on both sides of the static pressure pile driver, and to place the counterweight on the counterweight plate to provide sufficient reaction force for the steel sheet pile sinking, and to improve the stability of the device to avoid skewing; a second hydraulic rod is fixedly installed at both ends of the top of the linear motor, and the output end of the second hydraulic rod is fixedly connected to the bottom of the mounting seat, so that the second hydraulic rod can lift the moving plate from the ground, thereby facilitating the self-propelled device; the output end of the linear motor is slidably connected to a slide rail, so that before the static pressure pile driver moves by itself, the second hydraulic rod can lift the moving plate when the linear motor works, and after the moving plate is completed, the linear motor can drive the moving plate to move forward.
