Embodiment Construction

[0039] The following is attached Figure 1-5 The application is described in further detail.

[0040] The embodiment of the present application discloses an underground drainage pipeline.

[0041] like figure 1As shown, the underground drainage pipeline includes a bottom plate 1 on which two arc-shaped arched back plates 2 are integrally formed, and semicircular water holes 3 are respectively formed between the two arched back plates 2 and the bottom plate 1 . The circular drainage pipe is changed to a double-semicircular drainage pipe composed of two semicircular bow back plates 2 and the bottom plate 1, so that the drainage pipe can obtain a better structure on the basis of basically the same water passing area Stability; compared with the circular structure of the drainage pipe, the semicircular pipe has the support of the bottom plate 1, and the deformation amount will be significantly smaller than the circular structure of the drainage pipe when it is under downward pre...

Abstract

The invention relates to an underground drainage pipeline and a construction method, the underground drainage pipeline is applied to the field of drainage pipelines, the underground drainage pipeline comprises a bottom plate, two arc-shaped arch back plates are arranged on the bottom plate, and semicircular water passing holes are formed between the two arch back plates and the bottom plate respectively. The drainage pipeline has the technical effects that the possibility of uneven settlement and pavement cracking of the pavement above the drainage pipeline due to deformation of the drainage pipeline is reduced, and the laying effect of the drainage pipeline is improved.

Description

technical field [0001] The present application relates to the technical field of drainage pipes, in particular to an underground drainage pipe and a construction method. Background technique [0002] Underground drainage pipes refer to pipes laid underground to transport rainwater; most of the drainage pipes used in domestic municipal engineering are circular pipes, including steel pipes, ductile iron pipes, reinforced concrete pipes, steel wire winding corrugated pipes and high Density polyethylene (HDPE) or polyvinyl chloride (PVC) straight wall pipe. [0003] In the drainage pipeline construction process in the related art, the foundation trench is usually opened downward at the position where the pipeline needs to be laid on the pavement according to the design requirements, then the drainage pipeline is installed and laid in the foundation trench, and then the foundation trench is backfilled to restore the road surface. [0004] In the process of realizing the present ...
