Abstract
Concrete typical forms is spouted in movable preliminary bracing, arc formwork's surface is the arc structure, and arc formwork's the radius and the tunnel radius of being under construction equal, arc formwork's inner wall through the hydraulic stem with can move movable support and be connected each hydraulic stem along arc formwork's inner wall evenly distributed, the shotcrete pipe sets up between arc formwork and concrete wet blasting machine, and concrete wet blasting machine is installed on can moving movable support, the vibrator sets up on the arc formwork between each hydraulic stem. Can move movable support and install on laying the track, can move movable support and lay the track and pass through rollers matching. The utility model discloses can effectively reduce the construction degree of difficulty of preliminary bracing, can move movable support, shotcrete pipe, hydraulic stem and can effectively reduce the dust pollution who brings in the work progress through setting up, having reduced the construction and having polluted, the structure that adopts can be fine two lining constructions of assurance in waterproof material's planarization.
Description
Technical field
In this practical constructing tunnel process, strengthen quality control on construction, accelerate work progress, belong to tunnel support technical field.
Background technology
In current constructing tunnel process, preliminary bracing all adopts dampen shotcreting method to construct, and springback capacity is comparatively large, and once whitewash and often can not reach designing requirement, arch and the section of backbreaking repeatedly need be whitewashed and could be met, and spray concrete there are certain requirements operator and machinery.
In dampen shotcreting method work progress:
1, concrete quality is wayward, and particularly water-cement ratio is with randomness; The concrete of wet shot sprays by being transported to wet-spraying machine after production technology production, and its match ratio is in slave mode completely, thus ensure that the quality of pneumatically placed concrete.
2, in operating process, in air, dust content is higher, and construction environment is poor, easily causes actual bodily harm to constructor.
Summary of the invention
It is large that the purpose of this utility model is to overcome rebound of shotcrete modulus in construction of shotcrete, can improve simultaneously and just prop up planeness and reduce construction cost, effectively to ensure that in two lining work progresss, waterproofing materials is smooth.
For achieving the above object, the technical solution adopted in the utility model is packaged type preliminary bracing spray concrete typified form, and this structure comprises movable supporting frame 1, shotcrete pipe 2, hydraulic stem 3, arc formwork 4, vibrator 5; Arc formwork 4 assembles assembling by little arc formwork, and each little arc formwork coordinates gap place to be filled with foam block; The surface of arc formwork 4 is arcuate structure, and the radius of arc formwork 4 is equal with construction tunnel radius; The inwall of arc formwork 4 is connected with movable supporting frame 1 by hydraulic stem 3, and the inwall of each hydraulic stem 3 arcuately template 4 is uniformly distributed; Shotcrete pipe 2 is arranged between arc formwork 4 and concrete spraying machine, and concrete spraying machine is arranged on movable supporting frame 1; Vibrator 5 is arranged on the arc formwork 4 between each hydraulic stem 3.
Described movable supporting frame 1 is arranged on to be laid on track, and movable supporting frame 1 is matched by roller with laying track.
Compared with prior art, the utility model effectively can reduce the difficulty of construction of preliminary bracing, and by arranging movable supporting frame, shotcrete pipe, hydraulic stem can effectively reduce the dust pollution brought in work progress, reduces construction pollution; The structure adopted well can ensure the planarization of waterproofing materials in two lining constructions.
Accompanying drawing explanation
Fig. 1 is the structural representation of packaged type preliminary bracing spray concrete typified form.
In figure: 1, movable supporting frame, 2, shotcrete pipe, 3, hydraulic stem, 4, arc formwork, 5, vibrator.
Detailed description of the invention
This practicality adopts packaged type stand masterplate arc length can determine according to Tunnel Design radius, and the general width of template is 2m, the thick 1cm of template.I iron adopts 20cm, and hydraulic stem adopts 5T, and vibrator vibrates 800W, shotcrete pipe 50mm, and wet-spraying machine adopts JRD-PS800 type concrete spraying machine.
Packaged type preliminary bracing spray concrete typified form adopts long 260 meters of template totally 2 meters × 11 pieces, i iron (20#A200*100), hydraulic stem 12, vibrator 9.
Template is detachable, can according to tunnel interior diameter and Height Adjustment size, and notice during use that template is fixed, whether nozzle blocks.
Concrete implementation step:
1, masterplate size is formulated according to on-site actual situations.
2, adopt hydraulic stem to add Gu Ding, to design elevation, and to fill up the gap between template with foam block.
3, spray match ratio to select.
4, suitable thickness is sprayed.
