Description

The auxiliary locator of super-front large pipe shed in a kind of Tunnel
Technical field
The utility model relates to the realm of building construction, particularly relates to the auxiliary locator of super-front large pipe shed in a kind of Tunnel.
Background technology
At present, (as: the fault zone when Tunnel Passing bad geological section, weak surrounding rock location etc.) steel tube shed need be performed, first is to ensure that in-cavity construction pipe canopy has enough working spaces and construction plant, second is also to ensure that steel tube shed inserts country rock according to the insertion angle of designing requirement, therefore conventional method is first form a working space expanded, namely tunnel excavation section is expanded, this expands section will outwards be amplified to 1-2 rice than former design section excavation contour line, 4-7 rice is extended along line direction, such guarantee steel tube shed squeezes into rock mass according to the angle of designing requirement.At bad geological section due to country rock self developmental joint fissure, self-stable ability is poor, when carrying out expanding section construction, not only the self-stability of country rock and the safety of construction make people worried, and perform expand section consume human and material resources, financial resources also often in invisible increase, schedule delays.
Utility model content
Embodiment of the present utility model provides the auxiliary locator of super-front large pipe shed in a kind of Tunnel, saves a large amount of human and material resources, financial resources and duration, and guarantees the safety of personnel and equipment in work progress.
For achieving the above object, embodiment of the present utility model adopts following technical scheme:
An auxiliary locator for super-front large pipe shed in Tunnel, comprising:
Bracket, described bracket comprises builder's staging, described builder's staging comprises 3 layers of operation platform with i iron processing; Wherein the height of every layer of platform and the width of whole bracket are determined by the design size that each tunnel is concrete;
In the front-end and back-end of described bracket, reinforcement of weld has an arch i iron separately; Wherein, the arch i iron of rear end is higher than the arch i iron of front end;
The arch i iron held in the rear with on the arch i iron of described front end according to certain pitch of holes corresponding offer some to emptying aperture, insert the seamless steel pipe being welded with a diameter and being greater than emptying aperture between often pair of emptying aperture, the angle of described seamless steel pipe and horizontal plane is 1 ° ~ 5 °; Wherein, described certain pitch of holes is 30cm-50cm;
Reinforcing bar is welded with between adjacent two seamless steel pipes; Described reinforcing bar is for guaranteeing the firm of each seamless steel pipe;
The bottom of described bracket is provided with anchor structure, and described anchor structure is used for described auxiliary locator and ground are connected firmly.
Optionally, supporting reinforcing structure is provided with between the second layer operation platform of described front end arch i iron and described bracket and third layer operation platform;
Supporting reinforcing structure is provided with between the second layer operation platform of described rear end arch i iron and described bracket and third layer operation platform.
The auxiliary locator of super-front large pipe shed in the Tunnel that technique scheme provides, not only need not perform daguanpeng construction chamber, and this positioner can be selected to be in due course to process, so, not only save a large amount of human and material resources, financial resources and duration, and also ensure that the safety of personnel and equipment in work progress.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
The Facad structure schematic diagram of the auxiliary locator of super-front large pipe shed in a kind of Tunnel that Fig. 1 provides for the utility model embodiment;
The side structure schematic diagram of the auxiliary locator of super-front large pipe shed in a kind of Tunnel that Fig. 2 provides for the utility model embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment provides the auxiliary locator of super-front large pipe shed in a kind of Tunnel, and as shown in Figure 1, described auxiliary locator comprises:
Bracket 1, described bracket comprises builder's staging, described builder's staging comprise with i iron processing, 3 layers of operation platform (the first operation platform 11, second operation platform the 12, three operation platform 13 as shown in Figure 1); Wherein the height of every layer of platform and the width of whole bracket are determined by the design size that each tunnel is concrete.In the front-end and back-end of described bracket 1, reinforcement of weld has an arch i iron separately; Wherein, the arch i iron 3 of rear end is higher than the arch i iron 2 of front end.As shown in Figure 2, the arch i iron 3 held in the rear with on the arch i iron 2 of described front end according to certain pitch of holes corresponding offer some to emptying aperture, insert the seamless steel pipe being welded with a diameter and being greater than emptying aperture between often pair of emptying aperture, the angle of described seamless steel pipe and horizontal plane is 1 ° ~ 5 °; Wherein, described certain pitch of holes is 30cm-50cm; Reinforcing bar 6 is welded with between adjacent two seamless steel pipes 5; Described reinforcing bar is for guaranteeing the firm of each seamless steel pipe; The bottom of described bracket 1 is provided with anchor structure 7, and described anchor structure 7 is connected firmly for making described auxiliary locator and ground.
Here it should be noted that, the builder's staging used in the utility model embodiment can be the builder's staging that tunnel construction site processes.
In addition, the height H that the arch i iron 3 of rear end is higher than the arch i iron 2 of front end, the angle [alpha] that can ensure to be inserted in seamless steel pipe 5 on often pair of emptying aperture 4 of offering and level ground is 1 ° ~ 5 °.
