The utility model discloses a setting up pre -reinforcing stake, reinforced concrete layer and drainage structures's integrated configuration, can increasing its structural strength on the one hand, on the other hand has also strengthened water discharge ability, and the reduction flood reduces sliding and collapsing of rock mass to the effect at the entrance to a cave, makes the wholeness of entrance to a cave structure get a promotion, and the reliability and safety of work progress improves.
Description
Technical field
The utility model belongs to Tunnel Engineering technical field, is specifically related to a kind of hole, tunnel pre-reinforcement structure.
Background technology
Along with motorway, the speeding up the construction of railway, Tunnel Engineering also sharply increases, but its security risk also can increase, particularly during construction tunneling hole in early stage, it may occur that come down and collapse phenomenon, causes security incident.
To going out the sliding hole, tunnel collapsed, applying pre-reinforcement antislide pile in advance is an ideal scheme, owing to pre-reinforcement pile foundation designs in compensation mechanism, cost is low, reduce the slippage of rock mass and the successful that caves in, can effectively ensure the stable of hole and construction safety, construction risk is avoided to occur, it is the new utilization of dynamic design theory in engineering, engineering design personnel's reference can be supplied, but prior art is relatively single, and not consider that the practical structures with the later stage combines, affect the globality of its structure, and then reduce structural strength and construction effect.
Practical novel content
In view of this, the purpose of this utility model is to provide a kind of hole, tunnel pre-reinforcement structure, and to solve, prior art construction is single, globality is not enough affects the problem of its reliability and security.
The purpose of this utility model is achieved through the following technical solutions:
A kind of hole, tunnel pre-reinforcement structure, comprise the pre-reinforcement stake in hole, tunnel limit wall and built-in edges wall, described pre-reinforcement stake is the door shape frame structure higher than hole, tunnel, door shape frame is across the both sides being arranged on hole, tunnel, insert underground 2-8m bottom door pillar, the waterways also comprise the reinforced concrete floor being arranged on a shape frame dual-side wall, being arranged on reinforced concrete floor be arranged on the drainage tray being connected bottom the wall of limit with waterways.
Further, described waterways is equidistantly arranged side by side, and the spacing distance in adjacent row ditch is greater than 2m.
Further, described pre-reinforcement stake can be connected with pipe canopy cover arch, inverted arch.
Further, described pre-reinforcement stake is the cast structure of at least three layers.
Further, the both sides being also included in hole, tunnel at least respectively arrange an anti-sliding post.
The beneficial effects of the utility model are:
The utility model is by arranging the unitized construction of pre-reinforcement stake, reinforced concrete floor and discharge structure, its structural strength can be increased on the one hand, strengthen draining ability on the other hand, reduce flood to the effect at hole, reduce the slippage of rock mass and cave in, the globality of structure of the window is got a promotion, and the reliability and safety of construction process improves.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or can be instructed from practice of the present utility model. Target of the present utility model and other advantages can be realized by specification sheets below and obtain.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
Fig. 1 is the structural representation of hole, a kind of tunnel of the utility model pre-reinforcement structure.
Embodiment
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail. It is to be understood that preferred embodiment is only in order to illustrate the utility model, instead of in order to limit protection domain of the present utility model.
As shown in the figure, hole, a kind of tunnel pre-reinforcement structure of the present embodiment, comprise the pre-reinforcement stake 2 in limit, hole, tunnel wall 1 and built-in edges wall, described pre-reinforcement stake 2 is the door shape frame structure higher than hole, tunnel 3, door shape frame is symmetricly set on the both sides at hole, tunnel 3, what make that natural force can be more balanced acts in pre-reinforcement stake 2, avoid the phenomenon occurring that stress concentrates local damage, underground 2-8m is inserted bottom door pillar, the structural capacity on itself and ground can be improved, strengthen its integral rigidity, in the present embodiment, door shape frame both sides metope arranges a reinforced concrete floor 4, impact construction is fallen under can avoiding surface surface dust, simultaneously, limit wall can be made to form one-piece construction, strengthen its structural capacity, the present embodiment arranges waterways 5 on reinforced concrete floor 4, and drainage tray 6 is set bottom the wall of limit, drainage tray 6 is connected with waterways 5, it is beneficial to rainwater, scenery with hills and waters draws to walk, reduce construction ground to be washed away by water, form pit and cause geologic hazard, increase its security further.
The present embodiment is by arranging the unitized construction of pre-reinforcement stake, reinforced concrete floor and discharge structure, its structural strength can be increased on the one hand, also draining ability is strengthened on the other hand, reduce flood to the effect at hole, reduce the slippage of rock mass and cave in, the globality of structure of the window is got a promotion, and the reliability and safety of construction process improves.
In the present embodiment, described waterways 5 is equidistantly arranged side by side, and the spacing distance between adjacent row ditch is greater than 2m, can improve its drain function.
In the present embodiment, described pre-reinforcement stake 2 can be connected with pipe canopy cover arch, inverted arch, forms pre-reinforcement stake, pipe canopy cover arch, inverted arch more complete stress system, strengthens the structural stability of its entirety.
In the present embodiment, described pre-reinforcement stake 2 is the cast structure of at least three layers, takes multilayered structure, and its intensity can be improved, meanwhile, also relatively independent between each layer, is beneficial to construction.
In the present embodiment, also comprise anti-sliding post 7, described anti-sliding post 7 at least respectively arranges one in the both sides at hole, tunnel, the soil body reactive force of the arbitrary side in hole, tunnel or dual-side can be stopped by anti-sliding post, to weaken the effect to pre-reinforcement stake, form the system of a complicated stop soil body reactive force.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although the utility model being described in detail with reference to better embodiment, it will be understood by those within the art that, the technical solution of the utility model can be modified or equivalent replacement, and not departing from objective and the scope of the technical program, it all should be encompassed in the middle of right of the present utility model.
