Embodiment Construction

[0078] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0079] Such as Figure 1-11 As shown, a corrugated steel pipeline anti-slip device for steep slope terrain includes a corrugated steel pipeline 8; at least one circumference of the corrugated steel pipeline 8 is provided with an anti-slip anchor group, and each anti-slip anchor group Each includes one anchor rod connected to the spandrels on both sides of the corrugated steel pipe 8 and one anchor rod on both sides of the spandrel. And the end is cohesive; the end of each anchor rod is fixed in the rock and soil 9 on the steep slope at the bottom of the corrugated steel pipe through the anchor body 7 .

[0080] The anchor rod includes a round steel connecting ring 2-1, a round steel connecting rod 2-2, a rectangular frame tensioner 3, an anchor rod 5 at the upper end of a corrugated steel pipe, an anchor ro...

Abstract

The invention discloses a corrugated steel pipeline anti-sliding device for abrupt slope terrains, and belongs to the technical field of pipe culvert fixing. The anti-slip structure comprises a corrugated steel pipeline, anti-slip anchor rod groups are arranged on the circumference of at least one position of the corrugated steel pipeline, each anti-slip anchor rod group comprises anchor rods connected to arch shoulders on the two sides of the corrugated steel pipeline and arch armpits on the two sides of the corrugated steel pipeline, the two anchor rods on the arch shoulders are symmetrically arranged, the tail ends of the two anchor rods on the arch armpits are outwards arranged, and the tail ends of the two anchor rods on the arch armpits are symmetrically arranged, and the tail ends of the two anchor rods on the arch armpits are inwards gathered; and the tail end of each anchor rod is fixed in rock soil of an abrupt slope at the bottom of the corrugated steel pipeline through an anchoring body. Anti-sliding of the corrugated steel pipe culvert is achieved through the anchor rod principle, and the advantages of being fast in construction and low in cost are achieved.

Description

technical field [0001] The invention relates to the technical field of fixing pipes and culverts, in particular to an anti-slip device for corrugated steel pipes used on steep terrain. Background technique [0002] As an important part of highway engineering, culvert is an important structure in the highway drainage system. Its function is to quickly drain the surface water along the highway and ensure the safety of the roadbed. The flow slope of the culvert is divided according to the hydraulic properties. When it is greater than the critical slope, it is a steep slope, otherwise it is a gentle slope. [0003] Corrugated steel pipes have the advantages of low requirements on the bearing capacity of the foundation, convenient and quick construction, good economy, low-carbon environmental protection, etc., so they have been more and more widely used in the design of highway bridges and culverts in recent years. In mountainous areas, the slope of the natural river channel is ...
