Problems solved by technology

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art. The purpose is to provide an artificial pipe jacking control method and control system to solve the problem that the direction deviation of the pipeline is prone to occur in the artificial pipe jacking, and the problem that it cannot be monitored and adjusted in time when the deviation occurs

Embodiment 1

[0035] like Figure 1-3 As shown, an artificial pipe jacking control method of the present invention includes the steps:

[0036] Step 1) There are two laser detection pipes 2 symmetrically in the pipe wall of each cement concrete pipe 1, and the laser detection pipes 2 can be formed by pre-embedded pipes (seamless steel pipes), or they can be formed by casting through molds;

[0037] Step 2) A PSD sensor 3 is arranged in each laser detection tube 2 of the cement concrete pipe 1 at the front end of the pipe jacking, and a computer 4 connected to the PSD sensor 3 is arranged outside the cement concrete pipe 1. The computer 4 is arranged in the caisson, which is convenient for Workers monitor the jacking direction of the pipe jacking in real time;

[0038] Step 3) Connect the cement concrete pipe 1 that is subsequently jacked with the end of the cement concrete pipe that has been jacked in, and the laser detection pipes of the two connected cement concrete pipes are aligned wit...

Embodiment 2

[0049] like Figure 1-3 As shown in the figure, an artificial pipe jacking control system of the present invention includes a jack and a cement concrete pipe, and is characterized in that: two laser detection pipes are symmetrically arranged in the pipe wall of each cement concrete pipe; A PSD sensor is set in each laser detection tube of the , PSD (Position Sensitive detector) is a position sensitive detector. It is divided into one-dimensional PSD and two-dimensional PSD two types of products. PSD is a PIN photodiode composed of one or two surfaces with uniform impedance, which has the advantages of high position resolution, simple reaction current, and fast (depending on the position of the light spot) compared with discrete element detectors.

[0050] There is a computer connected to the PSD sensor outside the cement concrete pipe; the cement concrete pipe that is subsequently jacked is butted with the end of the cement concrete pipe that has been jacked in, and the laser...

Abstract

The invention discloses a manual l jacking pipe control method and control system. Two laser detection pipes are symmetrically arranged in the wall of each cement concrete pipe, a PSD sensor is arranged at the position, on the front end of a jacking pipe, in each laser detection pipe of each cement concrete pipe, a computer connected with the PSD sensors are arranged outside each cement concrete pipe, and laser emitters are arranged at the position, on the outer end of the jacking pipe, in the laser detection pipes of one cement concrete pipe, laser emitted by the laser emitters is irradiatedon the PSD sensors to form light spots, the PSD sensors collect and record information of light spot position changes, and the computer analyzes collected data, the straightness error of the cement concrete pipes can be evaluated. Through manual adjusting of a jack, the jacking direction of the cement concrete pipes can be adjusted; in the manual jacking pipe construction process, the extension deviation of a pipeline underground can be corrected, the jacking direction is effectively controlled, a deviation correcting control system and a jacking device are integrated, safety is improved, thedifficulty of pipeline deviation correcting in the pipeline jacking process can be effectively reduced, and the comprehensive cost is reduced.

Description

technical field [0001] The invention relates to the technical field of artificial underground pipe jacking in municipal engineering construction, in particular to an artificial pipe jacking control method and a control system. Background technique [0002] In urban road widening and reconstruction projects, the geology is relatively complex. During construction, both the construction period and the closed traffic problem must be considered. If the construction is carried out according to the conventional construction methods (grooving and sloping, grooved support), the safety of surrounding buildings cannot be guaranteed. At the same time, the construction cost is increased, and the construction period cannot be guaranteed. In addition, in the conventional construction method, the use of grooved construction requires certain trench support measures. Once the construction environment changes, the construction conditions are complex, the construction period is long, the surrou...
