Method for connecting pipeline into existing box culvert

Abstract

The invention discloses a method for connecting a pipeline into an existing box culvert. The method for connecting the pipeline into the existing box culvert comprises the steps that firstly, an inspection well is vertically arranged close to the outer side of the embedded box culvert; secondly, a horizontal maintenance passage is arranged between the box culvert and the inspection well, and the two ends of the maintenance passage are made to communicate with the box culvert and the inspection well correspondingly; and finally, a guide-in opening is formed in the side wall of the inspection well, and the pipeline stretches into the inspection well through the guide-in opening and finally extends into the box culvert through the maintenance passage. By the adoption of the method for connecting the pipeline into the existing box culvert, an old pipeline can be connected into the box culvert, and thus management is facilitated; meanwhile, a gap does not exist between an embedded sealing ring and the junction end face of the box culvert, so that water seepage is avoided; and when the joint of two box culvert deforms, a good waterproof function can still be achieved through the embedded sealing ring and a compression ring, so that water seepage at the junction of the box culverts is completely avoided, and the safety of the junction and normal operation are ensured during connecting construction of the box culverts.

Description

technical field [0001] The invention relates to a method for connecting a culvert box and a pipeline, in particular to a method for connecting an existing box culvert to a pipeline. Background technique [0002] Box culverts refer to culverts built with reinforced concrete box-shaped pipe joints. Box culverts consist of one or more square or rectangular sections, generally made of reinforced concrete or masonry, but reinforced concrete is widely used, and box culverts in municipal engineering can be used to concentrate pipelines. However, the old pipelines in the early days still operate independently. [0003] In addition, because the waterproof structure adopted by the traditional box culvert is to place waterproof materials at the joints of the box culvert, since the box culvert is made of concrete, the interface is rough, and the waterproof material cannot be in good contact with the end surface of the box culvert interface, and it is easy to leak from the waterproof ma...

Problems solved by technology

[0003] In addition, because the waterproof structure adopted by the traditional box culvert is to place waterproof materials at the joints of the box culvert, since the box culvert is made of concrete, the interface is rough, and the waterproof material cannot be in good contact with the end surface of the box culvert interface, and it is easy to leak from the waterproof material. Water seepage between the interface end face of the box culvert

In addition, because box culverts are affected by changes in groundwater level, soil quality, and upper side loads, they are often prone to various deformations such as torsion and warping at their joints. Cracks at the culvert lead to failure of waterproofing of the box culvert
