Abstract
The utility model discloses an anti-shedding device for an inner arch of a tunnel, and belongs to the field of tunnel equipment. The anti-shedding device for the inner arch of the tunnel comprises stainless steel tubes, connecting tubes and a carbon fiber plate, wherein the arch-shaped stainless steel tubes are uniformly distributed on the carbon fiber plate; the stainless steel tubes are connected with one another through the connecting tubes; the stainless steel tubes and the carbon fiber plate are fixed together through rivets; and the stainless steel tubes are fixed with the connecting tubes through argon-arc welding. As long as the anti-shedding device is arranged in a tunnel, the structural strength is high; the chemical properties are stable; the danger of cement massive shedding is avoided; moreover, cumbersome of cement pouring is saved; and the labor cost is also saved.
Description
Technical field
The utility model relates to arch anti-drop device in a kind of tunnel, belongs to the tunnel device field.
Background technology
Current the current of mountainous region that greatly facilitate in tunnel, present tunnel generally are that the arch of bombing its top, good back is built perfect forming through cement, but high humidity in the tunnel; Improper ventilation; Very easily making moist, often cause arch cement bulk to come off, is a urgent problem.
Summary of the invention
The purpose of the utility model provides arch anti-drop device in a kind of tunnel.
The problem that the utility model will solve is the block caducous deficiency of arch cement in the existing tunnel.
For realizing the purpose of the utility model, the technical scheme that the utility model adopts is:
The arch anti-drop device comprises stainless steel tube, tube connector and carbon fiber board in the tunnel, is evenly equipped with the arch stainless steel tube on the carbon fiber board, interconnects through tube connector between the stainless steel tube.
Stainless steel tube and carbon fiber board are fixed together through rivet; Stainless steel tube and tube connector are realized fixing through argon arc welding each other.
The utility model has the advantages that: as long as this anti-drop device is installed in the tunnel, structural strength is big, stable chemical performance; Danger that the cement bulk comes off just can not take place; And saved loaded down with trivial details that cement builds, and also practiced thrift labor cost, should have a vast market space.
Description of drawings
Fig. 1 is the sketch map of arch anti-drop device in the utility model tunnel;
Among the figure: 1, stainless steel tube 2, tube connector 3, carbon fiber board.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
The arch anti-drop device comprises stainless steel tube 1, tube connector 2 and carbon fiber board 3 in the tunnel, is evenly equipped with arch stainless steel tube 1 on the carbon fiber board 3, interconnects through tube connector 2 between the stainless steel tube 1.
Stainless steel tube 1 and carbon fiber board 3 are fixed together through rivet; Stainless steel tube 1 is realized fixing through argon arc welding with tube connector 2 each other; Carbon fiber board has advantages such as structural strength height, corrosion resistance be strong.
The method for using of this device: as long as this anti-drop device is installed in arch place in the tunnel, owing to adopt steel pipe to combine with carbon fiber board 3, structural strength is big; Stable chemical performance; The danger that just can not come off, and saved loaded down with trivial details that cement builds, also practiced thrift labor cost.
