1. Roadheader

According to the method of excavation and balance of soil, it is divided into: manual excavator, squeeze roadheader, pressure balance roadheader, mud water balance roadheader, earth pressure balance roadheader.

Tool pipe: The mud-water balance pipe jacking machine without cutter head is also called tool pipe. It is the key equipment for pipe jacking. It is installed at the forefront of the pipe. Its appearance is similar to that of the pipe. The structure is a three-section double hinge pipe.

Function: Breaking the soil, orienting, correcting deviation, preventing landslides, mud out and other functions.

Composition: mud flushing bin (front), operation room (middle), control room (rear) are equipped with horizontal hinges and up and down correction cylinders to adjust the up and down direction (that is, slope), set vertical hinges and horizontal correction cylinders, and adjust the left and right directions (horizontal curve) ), mud ring, control room, left and right adjustment cylinders, up and down adjustment cylinders, operation room, suction pipe, mud flushing bin, grid, tool pipe structure

2. Jacking equipment

Main jacking system-main oil cylinder: 2～8, stroke 1～1.5m, jacking force 300～1000t/unit;

The jacking force of a single jack cannot be too large: the jack, the pipe section, and the material of the rear seat.

Main oil pump: 32-45-50MPa; console, high-pressure oil pipe.

Top iron: make up for insufficient cylinder stroke, thickness <cylinder stroke

Guide rail: pipe jacking guide

Relay room-relay oil cylinder, relay oil pump or main oil pump.

3. Engineering management

The main body of the pipe is generally circular, with a diameter of 1.5 to 3 m. Length 2-4m.

Types of pipe materials in China

Reinforced concrete pipe: above C50, the most used, used in short-distance sewers;

Steel pipe: ranked second in application, used for long-distance pipe jacking such as tap water, gas, and natural gas;

Steel pipe, reinforced concrete composite pipe: outer steel inner concrete, used for super long distance jacking;

Steel pipes and plastic composite pipes: outer steel and inner plastic, used for transporting strong acid liquid and high purity water.

4. Dumping equipment

Artificial excavation-when artificially excavating soil.

Screw conveyor-earth pressure balance pipe jacking machine.

Mud suction and discharge equipment-mud-water balance, mud-water aerated and balanced pipe jacking machine.

5. Relay ring

Pipe jacking resistance

Positive-unchanged

Side friction-Obviously as the jacking distance increases, the long-distance jacking pipe is divided into several sections, and a relay ring is set between the sections. The relay jacking equipment can make the subsequent sections only overcome the side friction of the jacking pipe section. can. Operate the relay ring cylinders in order from front to back, and the jacking pipeline can achieve long-distance jacking.

Relay ring——A number of relay oil cylinders are arranged in a ring in the relay ring, and the cylinder stroke is 200mm.

When the relay ring cylinder works, the rear pipe section becomes the back seat, which pushes the front adjacent pipe section to the front, and overcomes the side friction in sections.
