The above two reasons reduce the groove excavation surface, thereby reducing the amount of earthwork excavation and the overall amount of engineering waste; the earthwork excavated by the process can be used for groove filling, thereby realizing the resource utilization of the excavated earthwork: the reduction in the width of the groove slope top reduces the width of the steel plate, thereby realizing the reduction of the steel plate width. The 3D printing technology of pipelines can save labor for pipeline installation and save social human resources, while avoiding underground operations of personnel and improving the safety factor of construction. The tools used in the process can be circulated and reused, which is conducive to saving social resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] See also Figure 1-Figure 12 The present invention provides a construction process and apparatus for installing a pipe for a cover plate for urban renewal. The construction process comprises the following steps:

[0043] S1: Organize the urban renewal pipeline project data according to the design drawings, determine the center, direction, length, depth, inspection well location, red line range and other specific information of the renewal pipeline, conduct on-site positioning and laying out, and make corresponding markings in the construction site;

[0044] S2: Close the pipeline engineering site along the construction red line, vertically cut the original pavement structure layer along the upper edge of the trench layout results, break the original pavement structure between the two upper edges of the trench and dig it out. The excavated part includes the original pavement and part of the roadbed. The thickness of the excavated structure layer is not less than 40cm. After digging the road surface layer and part of the base layer, a concave construction groove is formed at the construction site. The width of the concave construction groove should meet the design requirements and be calculated as follows:

[0045]

[0046] Where B is the excavation width of the bottom of the pipeline trench;

[0047] D 0 ——Outer diameter of the pipe (mm);

[0048] b 1 ——The required width of the printing operation on one side of the pipe (mm);

[0049] b 2 ——Thickness of the support system on one side of the pipeline (mm);

[0050] The trench side slope is straight and not sloping.

[0051] S3: Locate the bottom edge of the pipeline trench along the bottom edge of the concave construction trench on both sides, mark it every 2 meters, and screw in the screw pile 1 vertically along the marked point;

The soil quality should be excavated on site, the organic matter content should not be greater than 5%, and the coarse particle size should not be greater than 5cm. The fluidized solidified soil is mixed on site for use in S10. The preparation is divided into two steps: 1. Mix the mixing soil and water evenly; 2. Add the curing agent and mix.

[0058] S6: On both sides of the pipeline trench, groove baffles 4 are installed along the smooth screws 1.3 of the screw piles 1 to form a vertical groove slope for overall protection;

[0059] The groove baffle 4 is made of a material with a certain strength and not easy to deform, and the installation should be firm.

[0060] When the trench is too deep and needs to be excavated in layers, after the upper soil is excavated, the trench baffle 4 is installed first, and the lower soil can be excavated after the upper layer is fully supported.
