Description

Technical Field

[0001] The utility model relates to the technical field of drainage construction, in particular to an anti-collapse device for water supply and drainage construction. Background Art

[0002] During the construction process of municipal engineering, the laying construction of water supply pipes and drainage pipes is a very important link. When constructing municipal water supply and drainage pipes, affected by the terrain, as well as the length and weight of the water pipes themselves, the water pipes are prone to collapse during construction. To solve this problem, a support structure is added outside the municipal water supply and drainage pipes to support the water supply and drainage pipes and prevent the collapse of the municipal water supply and drainage pipes. However, most of the existing support structures for municipal water supply and drainage pipes are for a single water supply and drainage pipe. When supporting multiple side-by-side water supply and drainage pipes, multiple support devices are required for support, making it difficult to support multiple side-by-side water supply and drainage pipes simultaneously, which affects the construction convenience.

[0003] The prior art CN218972010U discloses an anti-collapse device for municipal water supply and drainage construction, including a municipal water supply and drainage pipe, a first anti-collapse mechanism, a connection mechanism, and a second anti-collapse mechanism. The first anti-collapse mechanism is located at the outer end of the municipal water supply and drainage pipe, the connection mechanism is located at the left and right ends of the first anti-collapse mechanism, and the second anti-collapse mechanism is located at the lower end of the first anti-collapse mechanism. For this anti-collapse device for municipal water supply and drainage construction, when it is necessary to support multiple side-by-side municipal water supply and drainage pipes, first adjust the extension length of the extension rod and the distance between the two sleeves, adjust the distance of the first anti-collapse mechanism according to the distance between different municipal water supply and drainage pipes, and support multiple municipal water supply and drainage pipes with different distances. After adjustment, fix the extension rod with the positioning bolt. This device has a more compact structure and is more convenient to carry, improving the construction convenience.
