Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] The present invention provides following technical scheme:

[0039] like Figure 1-4 As shown, a deformation protection structure for underground pipelines includes a roadbed soil layer 1, a trapezoidal groove excavated downward along the roadbed surface 13 on the upper surface of the roadbed soil layer 1, and a groove bottom surface 5 at the bottom of the trapezoidal groove;

[0040] Specific as figure 1 As shown, several sections of underground pipe...

Abstract

The invention discloses a deformation protection structure of an underground pipeline and a construction method, and aims to guarantee the safety of the buried underground pipeline under the conditions of ground overload and close soil disturbance, the protection structure comprises a small groove and a foundation cushion layer which are arranged at the bottom of a groove, a pipe seat pillow base is placed in the small groove, and a pipe seat is placed in the pipe seat pillow base. An underground pipeline is placed on the pipe seat pillow base, supporting retaining walls are arranged above the foundation cushion layer, the supporting retaining walls on the two sides and the foundation cushion layer form a cavity, foamed cement light soil is cast into the cavity in a cast-in-place mode to package the pipeline, geotechnical bags are fully laid between the supporting retaining walls and the groove side slope, and the structure further comprises a bearing top plate arranged above the supporting retaining walls in a covering mode. The protection system is mainly used for solving the problem that in the existing urban road construction process, nearby pipelines are deformed and damaged and are difficult to protect, effective deformation control and protection can be conducted on the nearby pipelines in road construction, and the protection system and a pipeline structure are the same in service life, construction is convenient and rapid, and certain waterproof and damping protection effects are achieved.

Description

technical field [0001] The invention relates to the technical field of underground pipelines, in particular to a deformation protection structure and a construction method for underground pipelines. Background technique [0002] In recent years, with the rapid development of urbanization in China, urban road buildings have become more and more dense, and the corresponding underground pipe network has become more and more dense; the displacement and damage of underground pipelines often occur during the construction of existing municipal roads. [0003] For example, when building an urban subway station on a municipal road, there are often cases where the underground pipeline is adjacent to the foundation pit of the subway station or crosses the station. The displacement state and stress state of the body change, so that the adjacent underground pipeline is squeezed by the surrounding soil; when the underground pipeline is buried close to the foundation pit of the subway stat...
