Abstract
Description
Technical Field
[0001] The invention relates to the technical field of caisson construction, and in particular to caisson auxiliary equipment in a deep water level sandy soil layer. Background Art
[0002] A caisson is a shaft-shaped structure that is built by digging soil inside the well and relying on its own gravity to overcome the frictional resistance of the well wall and then sink to the designed elevation. The bottom is then sealed with concrete and the well hole is filled to make it a complete underground structure.
[0003] During the construction process, we encountered a high-water sandy soil layer. The soil structure was unstable and did not have drainage conditions. At the same time, a large amount of sand and water would surge inside the caisson, so we adopted a non-drainage sinking method. However, due to the poor stability of the sandy soil layer and the abundant groundwater in the caisson area, the caisson would tilt or sink too fast during the caisson operation. Summary of the invention
[0004] To solve the above problems, the present invention discloses a deep water sandy soil layer caisson auxiliary device, comprising a main body, on which a supporting mechanism is arranged. The supporting mechanism is used for supporting and straightening the caisson, thereby ensuring that the caisson can be lowered into the well in a correct posture.
[0005] The support mechanism includes a first channel steel, one end of which is rotatably connected to a second channel steel, a middle portion of which is rotatably connected to a third hydraulic cylinder, one end of which is extended to be provided with a third hydraulic rod, and the other end of which is rotatably connected to a side wall of the second channel steel. When the third hydraulic cylinder is actuated, the third hydraulic rod is extended and retracted, thereby changing the vertical state of the second channel steel.
[0006] Both ends of the second channel steel are provided with hydraulic motors, the side walls of the hydraulic motors are provided with guide wheels, and the side walls of the second channel steels are fixedly connected with inclination sensors. The rotating shafts extending from both ends of the hydraulic motors are fixedly connected with the second channel steels. When the hydraulic motors are working, the guide wheels thereon rotate. When the equipment is in use, the guide wheels and the caisson are closely arranged, and the speed below the caisson is controlled by controlling the rotation speed of the hydraulic motors.
[0007] Preferably, a slide groove is provided on the main body, and the first channel steel slides in the slide groove. The first slide groove slides so that the guide wheel is close to the side wall of the caisson. At the same time, when the equipment is not in use, the first channel steel is gathered in the slide groove as much as possible, reducing the overall size of the equipment and facilitating transportation.
[0008] Preferably, a baffle is fixedly connected to the first channel steel, and the support mechanism further comprises a second hydraulic cylinder, one end of which is fixedly connected to the main body, and a second hydraulic rod is extended from the other end of the second hydraulic cylinder, and the other end of the second hydraulic rod is fixedly connected to the baffle. When the second hydraulic cylinder is actuated, the second hydraulic rod is extended and retracted to realize the extension or retraction of the first channel steel on the main body, so that the first channel steel can be controlled to be sent out and the guide wheel is close to the caisson.
[0009] Preferably, a walking wheel is arranged at the lower part of one end of the main body, and a support plate is fixedly connected to the lower part of the other end of the main body. The main body can be lifted on one side of the support plate, thereby dragging the main body to transfer the equipment.
[0010] Preferably, the side wall of the main body is fixedly connected with a support member, the upper end of the support member is fixedly connected with a first hydraulic cylinder, the lower end of the first hydraulic cylinder is extended with a first hydraulic rod, and the lower end of the first hydraulic rod is conical. Since the equipment is used to support the caisson, the equipment needs to be fixed, and when the first hydraulic cylinder is working, the first hydraulic rod extends and is inserted into the ground, thereby fixing the equipment.
[0011] Preferably, a towing ring is fixedly connected to the side wall of the main body, and the towing ring is located above the support plate. A towing machine is used to connect the towing ring, and then the towing machine tows the device to move.
[0012] Furthermore, the interior of the main body is also provided with equipment powered by an internal combustion engine, a hydraulic pump connected to the internal combustion engine, an oil tank for storing hydraulic oil, an oil circuit, a valve, and a host computer for control.
[0013] Furthermore, during the caisson construction, several devices need to be used together to support the side walls of the caisson, and it is necessary to ensure that the combined force of the multiple devices supporting the caisson is zero.
[0014] The beneficial effects of the present invention are as follows:
[0015] 1. Multiple devices can be used in conjunction to clamp the caisson. If the caisson is tilted, the posture of the caisson can be adjusted by controlling the third hydraulic cylinder to ensure that the caisson can sink smoothly.
[0016] 2. A hydraulic motor and a guide wheel are provided. The guide wheel squeezes the side wall of the caisson. Through the action of the hydraulic motor, the caisson can be braked to control the caisson to sink at a stable speed to avoid the caisson from sinking too fast. BRIEF DESCRIPTION OF THE DRAWINGS
