Problems solved by technology

Traditional jacking technologies, such as cluster jacking, winch wire rope traction, and cylinder steel strand traction, are far from feasible due to the difficulty in speed coordination control, poor synchronization stability and safety, and long construction period. Meet the requirements of high technical difficulty, large engineering volume and short cycle in the construction of modern large projects

specific Embodiment approach

[0023] Specific embodiments: now in conjunction with the accompanying drawings the present invention is further described by computer control coordination, and completes the operation in the following order:

[0024] 1) start the computer control system 1, 2; and issue operation instructions in sequence;

[0025] 2) The thruster oil cylinder group 3 extends the cylinder to push the box culvert 4 forward;

[0026] 3) The displacement sensor group 5 feeds back the displacement signal;

[0027] 4) The oil pressure sensor 6 feeds back the oil pressure signal;

[0028] 5) Compare and control:

[0029] If the displacement is large, reduce the speed of the oil cylinder that produces this displacement;

[0030] If the displacement is small, increase the speed of the oil cylinder that produces this displacement;

[0031] 6) Continue to push the box culvert 4 to complete a cylinder stroke synchronously;

[0032] 7) The computer control system controls all the oil cylind...

Abstract

The invention relates to a computer hydraulic synchronous pushing method and relative device, belonging to the underground construction technique, which is characterized in that: the cylinder group (3) has a rigid fixing support (8) clinging its back base; a heel block (7) is arranged between the top arm of the cylinder group (3) and a box (4); the on-site controller (2) is connected to the main control system (1) with a computer, the signal wire of cylinder group (3), the control wire, the displacement sensor (5) mounted on the two sides of box (4) to push the cylinder group step-by-step to the destination. The invention has improved technique, high practicability, saved labor, and shortened operation period.

Description

Technical field: [0001] It belongs to the technical field of underground construction, specifically the application technology of computer hydraulic system in large-scale underground construction. Background technique: [0002] With the rapid development of information technology, information technology has been continuously applied in engineering, especially in large projects, such as the automatic hoisting system of large buildings. These technologies can greatly improve the construction quality and speed up the construction progress. Correspondingly, in underground engineering, improving the technical level of construction has far-reaching significance. [0003] In the large-scale box culvert jacking project, the box culvert to be jacked has the characteristics of large tonnage, large span, and large area, and the construction environment is limited. How to ensure the successful and accurate jacking of the box culvert is a major problem in this technology. Traditional ja...
