Detailed Description
The following embodiments are only intended to illustrate the present invention in detail, and do not limit the scope of the present invention in any way.
Example 1:
a leading large pipe shed convenient for rapid construction, the structure of which refers to fig. 1 to 3.
As shown in fig. 1, the advanced large pipe shed convenient for rapid construction includes a plurality of grouting steel pipes 2 driven into the soil along the upper edge of the construction surface 11 of the excavated underground space 1, as shown in fig. 2, the grouting steel pipes 2 in this embodiment are connected by two short steel pipes in sections, the two short steel pipes are a first short steel pipe 21 and a second short steel pipe 22, the first short steel pipe 21 and the second short steel pipe 22 are provided with grout outlet holes, so that the grouted grout can flow out from the grout outlet holes and be filled into the soil to be coagulated, and the front end of the second short steel pipe 22 at the forefront of the grouting steel pipe 2 is a pointed end 221, so as to conveniently drive the grouting steel pipes into the drilled holes. In this embodiment, two short steel pipes forming the grouting steel pipe 2 are connected through a quick connection component, the quick connection component in this embodiment is the hoop 23, as shown in fig. 3, the hoop includes an upper half hoop sheet 231 and a lower half hoop sheet 232, the upper half hoop sheet 231 and the lower half hoop sheet 232 are clasped at the end portion where the first short steel pipe 21 and the second short steel pipe 22 are connected, and the upper half hoop sheet 231 and the lower half hoop sheet 232 are connected through the bolt 233, which is faster in connection through the hoop 23 compared with a welding mode, and is beneficial to fast construction of a pipe shed. In addition, in a humid environment with much water in the underground space, the welding mode is not firm enough, and the connection through the hoop 23 is firmer than the welding.
