Problems solved by technology
[0002] During the construction of municipal rainwater and sewage pipelines in cities and towns, most construction sites have narrow working surfaces and cannot be deployed in a large area. For projects with a tight construction period, if the conventional construction method (trench excavation→support formwork→cushion (flat foundation) ) pouring→pipeline installation→support formwork→pipe socket pouring→backfilling), the construction period of two pouring concrete is long
At the same time, it will be very inconvenient to clean because of the problem of chiseling on the contact surface between the flat base and the pipe seat due to the two pourings; and the integrity and stability of the pipe are low, which is easy to cause the pipe to shift, and the straightness of the pipe installation cannot be guaranteed
In addition, using conventional construction methods, the hoisting belt is not easy to extract after the pipe is hoisted in place, and the installation efficiency is low

Embodiment Construction
[0018] Accompanying drawing is a kind of specific embodiment of the present invention. This embodiment comprises pipeline 1, and pipeline 1 is arranged on two pipeline pads 2, and the top of pipeline pad 2 is fixedly connected with pipeline stabilizing body 3 respectively, can make foundation one-time pouring complete, and pipeline stabilizing body 3 is connected with pipeline 1 respectively. Tangentially, hoisting holes 4 are respectively arranged on the pipe stabilizing body 3, which is convenient for construction and installation.
[0019] Adopt the construction method of large-diameter drainage pipeline of the present invention, construction step is:
[0020] (1) After the excavation of the trench, clean the bottom of the trench according to the elevation of the designed bottom of the trench. Under the premise of meeting the design bearing capacity of the foundation, hang a line between the two designed inspection wells to control the centerline position of the pipeline an...

The invention belongs to the field of municipal rainwater-sewage pipeline engineering technology and particularly relates to a large-caliber drainage pipeline construction assembly and a construction method thereof. The large-caliber drainage pipeline construction assembly comprises a pipeline and is characterized in that the pipeline is arranged on two pipeline underlay pieces, pipeline stabilizing pieces are respectively and fixedly connected above the pipeline underlay pieces and respectively tangent with the pipeline, and hoisting holes are respectively formed in the pipeline stabilizing pieces. The large-caliber drainage pipeline construction assembly has the advantages of being high in installation efficiency, integrity and stability of the pipeline are high, pipeline installation straightness and smoothness can be guaranteed, inconvenience caused by concreting twice can be avoided, and manufacturing cost is low.
Description
(1) Technical field [0001] The invention belongs to the technical field of municipal rainwater and sewage pipeline engineering, and in particular relates to a large-caliber drainage pipeline construction component and a construction method thereof. Used during construction. (2) Background technology [0002] During the construction of municipal rainwater and sewage pipelines in cities and towns, most construction sites have narrow working surfaces and cannot be deployed in a large area. For projects with a tight construction period, if the conventional construction method (trench excavation→support formwork→cushion (flat foundation) ) pouring→pipeline installation→support formwork→pipe seat pouring→backfilling), the construction period of two pouring concrete is long. At the same time, the two times of pouring will cause the problem of chiseling the contact surface between the flat foundation and the pipe seat, which is very inconvenient to clean up; and the integri...
