Problems solved by technology

[0003] In the construction of pipe jacking freezing technology, after all the pipe jacking is positioned and jacked, a temperature measuring device is needed to determine the temperature change around the pipe jacking. Each device is checked regularly to ensure the normal use of the device, and the installation and disassembly are very cumbersome

Embodiment 1

[0019] see Figure 1 to Figure 3 , the present invention provides a technical solution: a new type of pipe jacking for the construction of underground excavation space, including a pipe jacking 1 and a temperature measuring device, the temperature measuring device includes a strain gauge 2 and a transmission line 3; the pipe jacking 1 is Concrete pipe jacking, the concrete pipe jacking includes several sections, the strain gauge 2 is a temperature-sensitive strain gauge, the strain gauge 2 is connected with a transmission line 3, and a PVC pipe 4 is spirally arranged in the concrete jacking pipe before pouring , the outer diameter of the PVC pipe 4 is smaller than the wall thickness of the concrete jacking pipe, and the PVC pipe 4 and the two sides of the concrete jacking pipe are arranged in full length.

Embodiment 2

[0021] see Figure 1 to Figure 3 , On the basis of Embodiment 1, the present invention provides a construction method for a new type of pipe jacking used in underground excavation space construction, comprising the following steps:

[0022] a. First, position the pipe jacking 1, seal the PVC pipe 4 at one end of the pipe jacking 1 in the first section,

[0023] b. Then, pass the transmission line 3 with the strain gauge 2 along the PVC pipe 4 .

[0024] c. After the position of the first section of pipe jacking 1 is determined, the second section of pipe jacking 1 is connected to the transmission line 3 with the strain gauge 2 first. After connecting the transmission lines 3 on the first section and the second section, according to the corresponding position Push into the second section of the jacking pipe 1, and so on until all the jacking pipes 1 are installed.

[0025] During the operation of step c, it is tested whether the transmission line 3 can be used before each jac...

Abstract

The invention discloses a novel jacking pipe for underground excavation space building and a construction method thereof. The novel jacking pipe comprises a jacking pipe body and a temperature measuring device. The temperature measuring device comprises strain foils and transmission lines, and the jacking pipe body is a concrete jacking pipe body which comprises a plurality of sections. The strain foils are temperature sensitive type strain foils, the transmission lines are connected to the strain foils, and the concrete jacking pipe body is internally provided with a PVC pipe body in a spiral mode before being poured. The outer diameter of the PVC pipe body is smaller than the wall thickness of the concrete jacking pipe body, and the PVC pipe body and the two sides of the concrete jacking pipe body are arranged in a through length mode. The construction method of the novel jacking pipe comprises the steps that firstly, the jacking pipe body is positioned, the PVC pipe body of the one end of the first section of the jacking pipe body is sealed, and then the corresponding transmission line with the strain foil is led into along the PVC pipe body; the position of the first jacking pipe main body is determined, and then the transmission line with the strain foil is led into the second section of the jacking pipe main body along the PVC pipe body; and the transmission lines on the first section and the second section are connected, and then the second section of the jacking pipe main body is jacked according to the corresponding position.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a new type of pipe jacking and a construction method for construction of underground excavation spaces. Background technique [0002] Our country is in the stage of socialist development, and the degree of construction mechanization is relatively low. Therefore, the operating environment of construction is relatively harsh, and there are relatively many potential safety hazards. After the invention of pipe jacking technology and freezing technology, the construction environment on site has been greatly improved. The safe and stable construction environment not only improves the operation efficiency but also fully guarantees the life safety of construction workers. Therefore, the new type of pipe jacking freezing technology has been obtained by organically combining the two technologies. [0003] In the construction of pipe jacking freezing technology, after all ...
