Control method for realizing accurate receiving of pipe jacking machine

Abstract

The invention discloses a control method for realizing accurate receiving of a pipe jacking machine. Firstly, a set of pipe jacking machine is prepared, an orifice pipe of the device is embedded in areceiving well hole wall, in the installation process of the orifice pipe, the position of the orifice pipe needs to be measured, when the pipe jacking machine is close to a receiving well, the axis of the pipe jacking machine is measured and adjusted to guarantee that the pipe jacking machine can break the wall within the specified range, and control operation is performed at the position of control nodes corresponding to a pipe section deceleration line, a pipe section breaking wall line and a pipe section termination line respectively. The method is advantaged in that through accurately controlling the crushing timing of the concrete wall, the probability of a nose entering a receiving compartment smoothly due to influence of large concretes is reduced, moreover, through accurately controlling the pipe jacking machine for receiving, so safe and smooth entry of the pipe jacking machine into the receiving compartment is realized; through accurately controlling the pipe jacking machinefor receiving, the compartment is protected, the reuse rate is enhanced, and construction cost is reduced.

Description

technical field [0001] The invention relates to the technical field of tunnel operations, in particular to a control method for realizing accurate reception of a pipe jacking machine. Background technique [0002] According to the patent CN104455724A, a receiving device and a receiving method for a pipe jacking machine under high water pressure conditions are disclosed, wherein the receiving device and the method for receiving a pipe jacking machine under high water pressure conditions of the present invention have wide applicability. The method can be applied to various formations, especially formations with high water and soil pressure at the receiving end, poor geological conditions, and no end reinforcement. Moreover, the receiving cabin can be disassembled and assembled according to the on-site hoisting conditions to meet the site and transportation requirements. The method of the present invention has high safety. The receiving cabin body adopts the principle of mud-w...
