Push pipe construction method and push pipe device

Abstract

The invention provides a push pipe construction method and a push pipe device, and belongs to the technical field of architectural engineering equipment. The technical problems such as low construction efficiency of the conventional push pipe construction method are solved. The construction method comprises the following steps: a, digging a well; b, mounting equipment; c, jacking a drill head of the push pipe; d, jacking a pipeline; e, pumping mud; f, taking out a machine head, and the like. The push pipe device comprises jacks, a jack bracket, a sliding rail and a push pipe drill head, wherein the jacks are arranged on the jack bracket; the push pipe drill head is arranged on the sliding rail; telescopic rods of the jacks are towards the push pipe drill head; a circular back is arranged between the jacks and the push pipe drill head, and the circular back is attached to the end part of the push pipe drill head; the front end of the push pipe drill head is connected with a water inlet pipe and a mud outlet pipe, and hoisting equipment is also arranged above the sliding rail. According to the invention, in the process of jacking, water can be injected into the front end of the push pipe drill head through the water inlet pipe, excavated soil is changed into slurry by water currents, the slurry is discharged out of the mud outlet pipe, and the soil discharging efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of construction engineering equipment, and relates to a pipe jacking construction method and a pipe jacking device. 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 receiving pit. After...
