Abstract
The utility model provides a terminal fore shaft portal of inclined shaft is strutted belongs to the tunnel construction field. It has solved the problem that the terminal fore shaft of current inclined shaft lacks fine support. This terminal fore shaft portal of inclined shaft is strutted includes the arch fore shaft steelframe as the terminal fore shaft of inclined shaft, and two feet of fore shaft steelframe are respectively fixed with ground through lock foot anchor pipe, and lock foot anchor pipe has the crossbeam with fore shaft steelframe welded fastening, fore shaft steelframe top welding, and crossbeam both ends bolted connection has the stand, is equipped with the bracing between stand and the crossbeam. Support the terminal fore shaft of inclined shaft through arch fore shaft steelframe to and strengthen whole through crossbeam, stand and bracing, make supported effects better.
Description
Technical field
The utility model belongs to technical field of tunnel construction, relates to the supporting of a kind of inclined shaft end fore shaft door frame.
Background technology
Rail channel western railway car No. 2 tunnel the beginning and the end mileages in the middle and south, Shanxi are DK1076+119 ~ 1083+970, total length 7851m.Tunnel Passing granite, limestone and limestone clip page rock.Limestone pavement karst has agensis to growing, and comparatively large to the influence degree of engineering, particularly karst water gushing water problem should be considered in tunnel, and part location exists Karst Problem.Be limestone along the tunnel top earth's surface exposure of tunnel piercing direction in import to inclined shaft direction tunneling process, bottom is granite.Due to the lava that granite is a kind of volcano eruption, and be subject to the tectonite that suitable pressure swells in the molten state to veneer of crust.In veneer of crust is formed, movement cools down lentamente, invades top limestone simultaneously and causes joint fissure comparatively to grow, be rich in underground water possibility higher.Invade location at granite and limestone and gushing water, prominent mud phenomenon more easily occur, larger to tunnel construction infection.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provides the supporting of a kind of support performance better inclined shaft end fore shaft door frame.
The purpose of this utility model realizes by following technical proposal: the supporting of a kind of inclined shaft end fore shaft door frame, it is characterized in that: comprise the arch fore shaft steelframe as inclined shaft end fore shaft, fore shaft steelframe bipod is respectively fixed by lock pin anchor tube and ground, described lock pin anchor tube and fore shaft steelframe are welded and fixed, fore shaft steelframe welded top has crossbeam, and crossbeam bolts at two ends is connected with column, between described column and crossbeam, be provided with diagonal brace.
By arch fore shaft steelframe, inclined shaft end fore shaft is supported, and by crossbeam, column and diagonal brace, entirety is strengthened, make support effect better.
In above-mentioned a kind of inclined shaft end fore shaft door frame supporting, described fore shaft steelframe adopts work 20 i iron solid matter, has 2 Pin.
Therefore resistance to overturning is higher.
In above-mentioned a kind of inclined shaft end fore shaft door frame supporting, fore shaft steelframe bipod is respectively by being no less than 4 φ 42 and locking pin anchor tube and ground being fixed.
Therefore connect more firmly stable.
In above-mentioned a kind of inclined shaft end fore shaft door frame supporting, described crossbeam, column and steel diagonal brace are respectively I20a shaped steel crossbeam, I20a shaped steel column and I20a shaped steel diagonal brace.
In above-mentioned a kind of inclined shaft end fore shaft door frame supporting, described crossbeam is welded and fixed by 2 φ 42 ductules and fore shaft steelframe.
Existing standard part is adopted to be easy to draw materials.
In above-mentioned a kind of inclined shaft end fore shaft door frame supporting, described fore shaft steelframe sprays and is coated with the thick concrete of 25cm.
Therefore, after integral erection, covered by concrete and play reinforcement stabilization.
Compared with prior art, the utility model tool has the following advantages:
By arch fore shaft steelframe, inclined shaft end fore shaft is supported, and by crossbeam, column and diagonal brace, entirety is strengthened, make support effect better.
