To carry out pipe jacking engineering in quicksand geology, mud-water balance pipe jacking construction technology is a very good choice. At first jacking is the beginning of the whole process of jacking. Its success and failure are related to the quality of all engineering projects. Therefore, the mud-water balance jacking pipe manufacturer will carry out a detailed description of the process for you.

The first step of the mud-water balance pipe jacking machine is a rotten hole. Before the rotten hole, take measures to avoid the collapse of sand or weathered layer at the side of the hole. Jacking is carried out in the well-proportioned loess layer, and bricks are generally used to seal the door; in the gravel soil, two methods can be selected, deep mixing piles and high pressure spraying. The manufacturer of the mud-water balance pipe jacking machine strongly recommends high-pressure spraying and spinning. This type of method has relatively low engineering cost and higher safety performance.

The second step of the mud-water balance pipe jacking machine is to bury the pipe jacking equipment. After the door seal is eliminated, the main shaft of the mud-water balance pipe jacking machine is started, and the main jacking hydraulic cylinder is used to gradually send the pipe jacking equipment halfway. Take care to avoid the main shaft being placed in the gravel soil, and to control the jacking rate and the pipe jacking equipment at the outlet. Add gussets on the upper and lower sides to prevent it from turning.

The third step of the mud-water balance pipe jacking machine is to connect the two concrete pipes behind the engine and the engine pipe to generate the overall elevation and centerline of the jacking section.

　　 After the above process is carried out, the original jacking work is carried out. The construction company of the mud-water balance pipe jacking machine must slow down, carry out an all-round accurate measurement, and draw a trend chart for easy analysis.
