Description

Technical Field

[0001] The present invention relates to the technical field of tunnel construction, and in particular to a device and method for synchronous curved translation construction of a shield machine and a rear supporting trolley. Background Art

[0002] With the development of cities, the utilization rate of urban underground space has gradually increased, and urban transportation and pipeline corridors are increasingly developing underground. The shield method is a fully mechanized construction method in the dark excavation construction method. It is increasingly widely used because it does not affect ground transportation and facilities, is suitable for various strata, has safe construction, and has a fast excavation speed. It often has technical and economic advantages in the construction of tunnels with greater burial depths and longer intervals.

[0003] As a high-cost and high-efficiency mode of transportation, urban subways are usually built in densely populated areas in order to increase passenger flow during the operation period and reduce the pressure of principal and interest repayment. Subway stations are also often located on major traffic arteries where people gather. In order to reduce the impact on ground traffic, dark excavation or covered excavation construction is usually selected when conditions permit. There are often no hoisting shafts or only small hoisting shafts on the ground, which cannot meet the hoisting conditions of the subsequent supporting trolleys. This results in the need for the subsequent supporting trolleys to be horizontally transported in the tunnel to the large-sized hoisting shaft near the station and then hoisted to the ground.

[0004] In addition, in order to save the cost of temporary construction sites and facilities, temporary facilities such as shield construction slag pits, circulating water pools, dormitories, canteens, etc. are usually set up at the same site. For double-track tunnel construction in the same section, after one tunnel is completed, the shield machine and the supporting trolley need to be re-transferred to the starting station for re-assembly and debugging before the second start of construction of another tunnel or adjacent section tunnel. In order to save the cost of hoisting and transfer of shield equipment, the supporting trolley is usually returned to the starting station by horizontal transportation in the tunnel.

[0005] The existing technology mainly uses the method of continuously extending the trolley moving track to move horizontally to the tunnel entrance and then lifting it out. This method has the following disadvantages: (1) It is necessary to continuously extend the rails and place triangular sleepers, which is labor-intensive and inefficient. (2) The safety and reliability are low. The longitudinal slope of the tunnel is usually 5‰ to 30‰, which is prone to dangerous situations such as slipping. Summary of the invention

[0006] The purpose of the present invention is to solve the defects in the prior art and to propose a construction device and method for synchronous curved translation of a shield machine and a subsequent matching trolley.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0024] 1. During the construction, only steel pipes, H-shaped steel, pins and steel plates were used as steel structure materials; only a small amount of welding was used to connect the steel pipes with the two separate platforms at the bottom of the trolley.
