Embodiment Construction

[0043] The following is attached Figure 1-6 The application is described in further detail.

[0044] The embodiment of the application combines specific construction cases to disclose a non-excavation directional drilling construction method for pipeline buried channels, which is suitable for municipal sewage pipe network construction projects, especially for municipal municipalities in township areas with dense building groups and large traffic. Pipe network construction. A certain sewage treatment plant and pipe network project is selected as a rainstorm-prone area, surrounded by mountains on three sides in a fan-shaped structure, low-lying in the middle, and facing the sea outside. The geological conditions of the project location are complicated. Refer to figure 1 , the specific construction method includes the following steps:

[0045] Step 1. Construction preparation:

[0046] 1.1 Choose PE solid-wall pipe 1 that is resistant to external pressure, good flexibility, a...

Abstract

The invention relates to a trenchless directional drilling construction method for a pipeline burying channel. The trenchless directional drilling construction method comprises the following steps that 1, pipe distribution is conducted, specifically, hot melting connection is conducted on the end faces of two PE solid-wall pipes; 2, directional drilling is conducted, specifically, a working pit and a receiving pit are manufactured, and a directional drilling machine is adopted for hole drilling; 3, back chambering construction is conducted, specifically, chambering is conducted in a step-by-step chambering mode to form a pipeline; 4, the pipe is pulled back, specifically, the pipe is pulled by adopting a pipe puller; and 5, inspection wells are manufactured, specifically, foundation pits are excavated in the two sides of an effective pipe section, the prefabricated inspection wells are installed, the prefabricated inspection wells are in waterproof connection with the PE solid-wall pipes, and then the foundation pits and the peripheries of the prefabricated inspection wells are backfilled. Only the working pit and the receiving pit need to be excavated in the ground, drilling, chambering and pipe pulling operations are carried out at the positions of the working pit and the receiving pit, and environmental influences such as multiple construction technology procedures, a largeamount of road surface damage and traffic obstruction caused by pipeline open excavation construction can be avoided.

Description

technical field [0001] The invention relates to the technical field of pipeline network construction, in particular to a non-excavation directional drilling construction method for pipeline buried channels. Background technique [0002] In recent years, with the continuous improvement of people's living standards and the continuous change of ideas and concepts, the emphasis on environmental protection has been put forward, and some cities have increased their efforts in environmental governance and carried out sewage treatment projects. [0003] During the construction of the municipal sewage pipe network, for some construction points with many underground pipelines and complex geological conditions, the use of open-cut pipeline construction methods will cause problems such as many construction technical procedures, traffic congestion, and serious road damage, which will seriously cause serious damage to residents’ daily travel. big impact.
