Rock Pipe Jacking Machine

Cutting head technology and performance requirements for rock pipe jacking machines

In hard rock environments, cutting heads must be able to handle rock formations of different hardness, especially when the rock hardness reaches 50-200 MPa. For such environments, the cutting heads of the jacking machine need to have high stability and durability. In order to cope with different types of rocks, the shape and size of the cutting heads also need to be optimized according to the specific soil and rock conditions. For example, some advanced rock pipe jacking machines adopt a replaceable modular cutting head design, so that during long-term construction, the cutting head can be replaced inside the equipment, reducing downtime and ensuring that the construction progress is not affected. This technology also reflects the breakthrough of modern equipment in operating efficiency and equipment maintenance.

The rock pipe jacking machine we provide uses industry-leading cutting head technology and can cope with a variety of construction environments from ordinary soil layers to giant rocks. Our machine not only uses a high-wear-resistant alloy cutting head, but also the cutting head design has been finely optimized to ensure that it can maintain efficient propulsion and stability even when facing hard rock formations. In addition, our equipment is equipped with an advanced secondary crushing system, which can effectively perform secondary crushing during the pipe jacking process, further improving construction efficiency and reducing construction risks.

Common problems and solutions at the construction site of rock pipe jacking machine

At the construction site of rock pipe jacking machine, there are many common problems, usually involving equipment stability, construction progress, changes in geological conditions, and construction safety. First of all, the stability of the equipment is often one of the most common challenges in construction. Since different types of soil and rocks often need to be traversed during construction, these changes may cause the propulsion force of the jacking machine under different geological conditions to be unstable, thereby affecting the operation efficiency. Especially in hard rock layers or areas with large rocks, the cutter head of the jacking machine may suffer from increased wear, affecting the normal construction progress. In addition, in construction with greater depth, the settlement problem of the equipment may also affect the propulsion force, causing the equipment to get stuck or propel slowly.

In response to these problems, the use of high-performance cutting heads and advanced propulsion systems is an effective way to solve the problem of equipment stability. Our rock pipe jacking machine is optimized for this problem. The equipment is equipped with high-strength alloy cutter heads, which can effectively cope with high wear in hard rock environments, reduce the frequency of cutter head replacement, and improve construction continuity. In addition, the propulsion system of the equipment is precisely designed to adaptively adjust the propulsion force to ensure that a stable propulsion speed can be maintained regardless of the geological environment.

Secondly, safety issues at the construction site often plague project progress, especially under complex geological conditions. Pipe jacking machine operators need to deal with highly concentrated forces and pressures. Once the equipment fails or the problem is not discovered in time, it may lead to accidents. In order to ensure construction safety, the monitoring system of the equipment plays a vital role. By monitoring the operating status of the pipe jacking machine in real time, the operator can grasp the various parameters of the equipment at any time, discover potential risks in time, and take measures to avoid accidents. Our "Rock Pipe Jacking Machine" is equipped with an advanced intelligent control system that can monitor the operating status of the cutter head, propulsion force and the overall health of the equipment in real time to ensure that the equipment operates efficiently within a safe range.

Another common problem is water seepage or groundwater influx during construction, which also poses a challenge to the operation of rock pipe jacking machines. When encountering complex groundwater levels, water seepage problems may cause unstable pressure in the operating area, which in turn affects construction efficiency. To deal with this problem, the waterproof design and sealing technology of the pipe jacking machine are crucial. By improving the waterproof performance of the equipment, the adverse effects of water flow on the equipment can be effectively prevented. Our rock pipe jacking machine is specially designed on the sealing system to ensure that the equipment can maintain stable operation even under geological conditions with abundant groundwater.
