Description
Technical field
The utility model relates to Metro station excavation gantry crane rail beam, specifically the track foundation of a kind of subway station straddle truck.
Background technology
China's city underground interval adopts shield method to construct substantially, must install straddle truck AT STATION, and traditional station Guan Liang is concordant with ground, and gantry crane rail beam directly utilizes Guan Liang, and two ends, station expanding reach adopts girder steel to connect.Now in order to reduce construction investment, owner designs Guan Liang lower than 2 meters, ground, above hat beam, retaining wall is set, Guan Liang cannot be utilized to make gantry crane rail beam, if utilize Guan Liang to do rail beam, just need retaining wall to form L-type retaining wall to extending out 1 meter with Guan Liang, two ends, station are that expanding reach adopts girder steel transition, and need to increase straddle truck.This method shortcoming be cost high, long in time limit, have a big risk.
Summary of the invention
The utility model in order to the making of the rail beam and basis thereof that solve existing subway station straddle truck exist cost high, long in time limit, have a big risk and increase the problems such as straddle truck, track and the basis thereof of a kind of subway station straddle truck are provided.
The utility model takes following technical scheme: the track foundation of a kind of subway station straddle truck, comprise and be divided into all fender posts of side of foundation ditch and the Guan Liang at fender post top, Guan Liang comprises non-bellend Guan Liang and bellend Guan Liang, bellend hat beam sides is provided with concrete beam, in concrete beam, reinforcing bar and non-bellend Guan Liang and bellend are preced with beam steel and are linked into an integrated entity, its arrangement of reinforcement is the same with girder steel, thickness of protection tier is 5cm, Guan Liang and concrete beam are provided with retaining wall, retaining wall inside is furnished with reinforcing bar, the width of barricade is 40cm, height is concordant with ground, barricade top is provided with pre-embedded steel slab, track is provided with on the upside of pre-embedded steel slab, track two ends are fixed by track clamp.
Compared with prior art, the utility model has the following advantages:
1) expanding reach concrete beam in two ends, station is linked to be entirety with hat beam steel, not only guarantees concrete beam rigidity, and reduces working procedure.
2) utilize barricade to make gantry crane rail beam, not only do not need retaining wall to extend out, and do not need to increase straddle truck height, guarantee straddle truck security of operation.
3) Guan Liang designs retaining wall, not only reduce drilled pile length, and first support is moved down, reduce and support support, greatly reduce construction cost.
The utility model makes full use of concrete beam that bellend increases and station retaining wall makes the advantage of gantry crane rail etc., not only accelerating construction progress, reduces construction cost, and guarantees straddle truck security of operation, simplify working procedure.Have that technique is simple, advanced technology, the advantage such as practical.
Adopt this technology to have successfully completed Shenyang Metro No. 9 line 7 Biao Wang river way station gantry crane rail beam constructions, filled up the blank that China's subway station retaining wall does gantry crane rail beam construction technology, achieved good economic benefit and social benefit.
Accompanying drawing explanation
Fig. 1 is floor map of the present utility model;
Fig. 2 is the utility model A-A generalized section;
In figure: 1-Guan Liang, 2-barricade, 3-pre-embedded steel slab, 4-track, 5-track clamp, 6-fender post, 7-concrete beam.
Detailed description of the invention
As Fig. 1, shown in 2, the track foundation of a kind of subway station straddle truck, comprise and be divided into all fender posts 6 of side of foundation ditch and the hat beam 1 at fender post 6 top, hat beam 1 comprises non-bellend Guan Liang and bellend Guan Liang, bellend Guan Liang side is provided with concrete beam 7, in concrete beam 7, reinforcing bar and non-bellend Guan Liang and bellend are preced with beam steel and are linked into an integrated entity, its arrangement of reinforcement is the same with girder steel, thickness of protection tier is 5cm, retaining wall 2 is provided with on the upside of hat beam 1 and concrete beam 7, retaining wall 2 inside is furnished with reinforcing bar, the width of barricade 2 is 40cm, height is concordant with ground, barricade 2 top is provided with pre-embedded steel slab 3, track 4 is provided with on the upside of pre-embedded steel slab 3, track 4 two ends are fixed by track clamp 5.
During concrete enforcement, comprise the following steps:
Step one, Guan Liang constructs.
A, hat beam steel bar colligation; Unsettled section of B, bellend sets up reinforcing bar; Pre-buried barricade vertical reinforcement after C, template erection; D, concreting.
Step 2, barricade and track are installed.
Steel plate at the bottom of pre-buried track after A, barricade reinforcing bar binding; B, install template after carry out concreting; C, install track, and on pre-embedded steel slab welded rails clamp.
