Description
Technical field
The present invention relates to a kind of tunnel grillage processing unit (plant)s, are related to the tunnel constructions such as highway, railway, municipal administration.
Background technique
Currently, with railway, highway, the raising of railway construction standard and difficulty of construction increasing, mountain tunnel institute accounting
Weight is larger.The main deficiency of profile steel frame used by previous has:
1, fashioned iron quality is big, processing when consumptive material it is big, it is at high cost；
2, processing profile steel frame needs the large scale equipments such as fashioned iron bending machine, plate shearing machine, takes up an area larger.
3, profile steel frame is set up difficult, be not easy with excavation face it is closely connected, it is easy to form behind in profile steel frame after gunite concrete
Cavity, gunite concrete leakiness.
And grillage light weight is used, installation speed is fast, and steel using amount is few, can be mixed with injection well using grillage
Solidifying soil good combination, cooperative bearing, and stress is small, stress distribution is uniform.When tunnel's entrance and exit is provided with station, interchange area
When, tunnel cross-section widens variation frequently, when country rock is poor, causes grillage processing quantity more, and tooling transformation frequently, processes
At rear stacking tooling occupied ground, larger, waste of material, cost payout increase.
Summary of the invention

It tethers and connects.
3. grillage Adjustable tool apparatus structure in tunnel according to claim 1, it is characterised in that: grille arch
Frame Adjustable tool bottom fixing tool (1) is bent using I-steel according to set radian, should be noted that value is widened in tunnel when bending
Different situations, fixedly adjustable section steel plate length control thereon (prevents from toppling) within 50~70cm, fluting, slot in the middle part of steel plate
Mouth width degree 3cm, mobile convenient for top tool, grillage fixing steel plate (5) considers processing size, arch master according to design size
Muscle position grooving, notch width are greater than arch main reinforcement diameter+1cm and are advisable, and in order to arch taking-up, the above material takes on the spot
Material, for grillage of the same race, it is only necessary to process a set of standard frock can solve difference widen value section grillage processing,
It saves place, reduce waste of material, reduce labour cost, can effectively reduce cost payout.
4. tunnel grillage according to claim 2 processes Adjustable tool device, it is characterised in that: tunnel lattice
Grid arch Adjustable tool bottom fixing tool (1) is placed directly on processed ground, and fixation steel plate (2) spot welding is adjusted
On fixing tool, fluting in the middle part of fixation steel plate is adjusted, slotting length is width 3cm at steel plate edge 10cm；It connects thereon
Steel plate (3) and vertical steel plate (4) are welded into T-shape structure, position auger shell bolt of the junction steel plate at the 5cm~10cm of end
Hole, vertical steel plate (4) and grillage fixing steel plate side are welded, and shape is integral, thereafter according to the radius of design requirement, arc
The long position determined on adjustable fixation steel plate (2), marking, then junction steel plate (3) and I-steel top are adjustable solid
Determine steel plate (2) and be connected by screw bolts simultaneously fixation, completes tooling adjustment.
Beneficial effects of the present invention:
Every kind of lining section widens value according to difference and only needs to process a set of Adjustable tool, reaches and saves material, reduces
The purpose of cost.This is reasonable in design, simple and practical, easy to operate, gathers materials on the spot, and lining section difference of the same race widens value
Arch processing, which only needs to process a set of Adjustable tool, can be solved, can effectively solve existing arch tooling processing take a lot of work, be time-consuming, work
The phenomenon that people's large labor intensity, reduces place and waste of material, reduces construction cost.
