Background technique
In heating-power tunnel, need to be arranged the bracket of fixed heat distribution pipeline.Bracket usually will be by pipeline and its attachment
These thrusts are transmitted on tunnel structure by thrust, bracket again.In order to resist these thrusts, the soil body and tunnel are usually utilized
The frictional force of body structure surface is resisted.But when structure thrust is excessive, frictional force will be unable to resist, structure will be split by pushing away, this
Huge threat is caused to the safety of structure.So when frictional force can not offset heat distribution pipeline bring thrust it is necessary to benefit
With horizontal earth pressure (i.e. the soil body formed in the horizontal direction pressure) Lai Zengjia drag.Common practice is in the outer of tunnel structure
Antiskid item is set on circumferential surface.Antiskid item is that part increases tunnel top or bottom external thickness, using reinforcement with do not thicken
The platform section facade that is formed between the tunnel of part forms the soil pressure that structure level is subject to.The inventors discovered that existing antiskid
Item is cross-section form.The height of platform section is influenced by thrust size, when thrust is excessive, it is necessary to design higher antiskid
Item.This not only increases difficulty of construction, and also adds the dosage of structural material, causes waste.Inventors believe that such as
The whole segmentation structure of antiskid structure unit is changed into segmentation structure and forms concaveconvex structure between section and section by fruit, then can be with
The stabilization tunnel structure that the facade contact area and the soil body for increasing the soil body in the case where reducing structural material dosage are formed
Horizontal applied force.In view of this, the present inventor's design completes the present invention.
Summary of the invention
The present invention is in view of the deficiencies in the prior art or insufficient, provides a kind of segmented heating-power tunnel antiskid item, leads to
It crosses and uses axial segmentation structure to form concaveconvex structure between section and section in an antiskid structure unit, can both reduce anti-
Draw runner self weight and structural material dosage, and increase the soil body formed stabilization tunnel structure horizontal applied force, thus be conducive to
The anti-thrust from heat distribution pipeline and its attachment by the fixed bracket transmitting of heat distribution pipeline, improve tunnel structure anti-slide performance,
Construction efficiency, safety coefficient reduce difficulty of construction.
