Risk factors of pipeline trenchless engineering
Construction is mainly to avoid risks. Nowadays, more and more pipe jacking are used, so it is necessary to conduct risk assessment of pipeline trenchless engineering. Let's talk about the risk factors of pipe jacking construction. Most of the risks of pipe jacking can be solved in the early stage. Let's understand the risk factors of pipeline trenchless engineering.
The risk factors of pipeline trenchless engineering can be roughly divided into four categories:
1. low quality
1. There are more silt in the bottom of the water; 2. There are more debris in the water; 3 The flow rate of water is higher. The above three factors will affect the normal construction of pipe jacking.
In the trenchless construction of pipelines, the factors of equipment must also be considered in the risk factors. The more prone problems of the equipment are: 1. The drill is stuck and does not move; 2. Some parts are damaged, such as the drill pipe; 3. The pipe remains in the hole; 4. The hole is collapsed.
Under severe weather conditions, mud-water balance pipe jacking construction is prohibited, especially in seasons with typhoons and heavy rains.
This project must have a reasonable design route before construction to ensure that the construction of the mini pipe jacking machine will not cause inconvenience to other things: 1. vertical route; 2. horizontal route.
