Embodiment 1

[0018] Embodiment 1: as figure 1 As shown, the pipe jacking device includes a pipe body, and a pipe sleeve 2 is set on the outside of the pipe body 1. The side wall of the pipe body 1 is provided with an installation hole, and the pipe sleeve 2 is provided with a pipe sleeve 2 opposite to the installation hole. Through hole, the pin shaft 3 that passes through the through hole of the pipe body and the pipe sleeve is installed in the installation hole, and a stop pin 4 is installed at one end of the pin shaft 3 on the inner wall of the pipe body 1, and a stop pin 4 is installed on the sleeve pipe 2 One end of the pin shaft 3 on the outer wall is provided with a stopper boss 5; the upper and lower sides of the casing 2 are provided with seepage pipes 6, and the seepage pipes are provided with grooves 6 which can be fitted with the stopper boss 5. After the pipe jacking device is pushed into the reserved position, the stop pin 4 is removed, and the pin shaft 3 is pushed along the...

Embodiment 2

[0020] Embodiment 2 is further defined on the basis of embodiment 1: the seepage pipe is provided with a plurality of seepage holes, and the seepage holes are evenly distributed on the pipe wall of the seepage pipe. The moisture in the silt can first seep into the seepage pipe, so that the silt can be preliminarily seeped and fixed.

Embodiment 3

[0022] Embodiment 3 provides a pipe jacking device. The difference from the embodiment is that the pin shaft 3 is replaced by a bolt, and a stop nut is installed on one end of the bolt located on the inner wall of the pipe, and a stop nut is installed on the outer wall of the casing. One end of the pin shaft is provided with a stop boss. There are bolts and pins that can meet the same use requirements, and the use of bolts instead of pins is convenient for installation and saves costs.

Abstract

The invention discloses a pipe jacking device. The pipe jacking device comprises a pipe body. The outer portion of the pipe body is sleeved with a pipe sleeve. A mounting hole is formed in the side wall of the pipe body. A through hole opposite to the mounting hole is formed in the pipe sleeve. A pin shaft penetrating through the pipe body and the through hole of the pipe sleeve is installed in the mounting hole. A stop pin is installed at the end, positioned on the inner wall of the pipe body, of the pin shaft. Stop bosses are installed at the end, positioned on the outer wall of the sleeve,of the pin shaft. Water seepage pipes are correspondingly arranged on the upper surface and the lower surface of the sleeve, and a groove capable of matched with the corresponding stop boss is formedin each water seepage pipe. After the pipe jacking device is pushed to the reserved position, the stop pin is removed, the pin shaft is pushed along the mounting hole and the through hole, and the stop bosses of the pin shaft are installed in the grooves to separate the pipe body from the pipe sleeve; and while concrete in the water seepage pipes is used for silt fixation, the pipe sleeve and thewater seepage pipes are installed to separate the pipe body from the silt, thus the shifting during pushing is avoided, the construction speed is increased, and the waste of resources is solved.

Description

technical field [0001] The invention relates to the technical field of pipe jacking construction in construction engineering, in particular to a pipe jacking device and a pipe jacking construction method. Background technique [0002] Pipe jacking construction is a non-excavation construction method, which can achieve pipeline burial without excavation or less excavation. It overcomes the friction between the pipeline and the surrounding soil by means of the jacking force generated by the jacking equipment in the working pit, and the The pipeline is pushed into the soil according to the designed slope and direction, and the soil is transported away. After one section of pipe has been jacked into the soil layer, the second section of pipe continues to be jacked. The principle is to push the tool pipe or roadheader through the soil layer from the working pit with the help of the thrust of the main jacking cylinder, the pipe room, and the relay room. Push all the way into the ...
