Embodiment Construction
[0042] The present invention will be further described below in conjunction with the examples. The description of the following examples is provided only to aid the understanding of the present invention. It should be pointed out that for those skilled in the art, without departing from the principle of the present invention, some improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
[0043] refer to figure 1 As shown, the construction method for the suspension and encapsulation combined protection pipeline includes the following construction steps:
[0044] 1) Construction preparation: Excavate the pipeline laying groove 1 and compact the soil around the pipe 2, and prepare the materials and devices required for construction;
[0045] 2) Suspension protection of water supply and drainage pipes: first place the water supply and drainage pipes...

The invention relates to a construction method for suspending and encapsulating combined protection of a pipeline. The construction method comprises the following steps of (1), construction preparation; (2) suspending protection of a water supply and drainage pipe; (3) suspending and encapsulating construction of the water supply and drainage pipe ; (4) laying a temporary road passage support body; (5) constructing a pipe periphery filling body; and (6) construction of a pipe top sealing body. The method has the beneficial effects that a suspension cross beam at the upper part of the water supply and drainage pipe is utilized, and the position of the water supply and drainage pipe is transversely and vertically corrected by adopting transverse position correcting bodies and sling chain position control nuts, so that the position control accuracy of the water supply and drainage pipe is improved; meanwhile, a suspension beam toothed plate is arranged on the lower surface of the suspension cross beam, so that the connecting strength of the suspension cross beam and a soil body around the pipe can be improved; and groove wall jacking bolts and groove wall pressing plates are arrangedbetween the suspension cross beam and the groove wall of a pipeline laying groove, so that the stability of a soil body on the groove wall of the pipeline laying groove is improved.
Description
technical field [0001] The invention relates to a construction method of suspension encapsulation combined protection pipeline which can improve the construction efficiency of pipeline encapsulation, reduce the impact of construction on water supply and drainage pipes, and improve the filling quality of fillers around pipes, and is suitable for water supply and drainage pipes in municipal or water conservancy projects Laying works. Background technique [0002] The laying of water supply and drainage pipelines is an important construction link in engineering projects such as urban water transmission and distribution, flood control and drainage, and sewage collection and transportation. have a serious impact. [0003] In the prior art, there is a pipeline rapid encapsulation pouring device and its construction method. The device includes concrete pipelines and fixing nuts, an upper ring formwork, a lower ring formwork, and clamps for the ends of two concrete pipelines connec...
