Abstract
The utility model discloses a pouring moldboard for a tunnel trench. A moldboard is manufactured into an integral type moldboard according to the shape of a trench, the left side face and the right side face of the moldboard are inclined, the moldboard gradually contracts from top to bottom, and the top surface of the moldboard is an arc surface. In a pouring operation process, the moldboard is placed in a pouring layer correspondingly and is located, concrete is poured into the pouring layer, and after concrete reaches the intensity requirement of mold removing, the construction of the tunnel trench is completed. The moldboard can be fast placed and recovered in a construction process, repeated assembly is not needed, the pouring process is fast and convenient, the concrete falling on the moldboard can slide into the pouring layer along the arc surface, and does not accumulate on the top portion of the moldboard, and the pouring process is enabled to be smooth and high in efficiency.
Description
Technical field
The utility model relates to the formwork structure that Central drain and side hook in the constructing tunnel are built use.
Background technology
In the tunnel construction engineering, the needs because of circuit laying and draining need to arrange Central drain and lateral sulcus in the tunnel.These Central drains and lateral sulcus need to use corresponding template moulding in casting process.At present, this class Central drain template and lateral sulcus template all are split-type structurals, and it is comprised of scattered limit mould and bed die etc., need the artificial component combination that these are scattered to be spliced into the shaped as frame template during construction, pour into a mould again.Because the tunnel is usually all very long, reaches several kilometers even tens kilometers, the shaped as frame template often only has several meters, and in dismounting and the assembling repeatedly of template in construction process needs, it need to consume a large amount of human and material resources, work consuming, consuming time, and efficient is extremely low.And the template that temporary assembly forms produces the defectives such as slit and dislocation easily between plate and plate; The integral linear of the Central drain of cast is difficult to control, affects outward appearance.In addition, the combination of template is also higher to operating personnel's technical requirements; In addition, concrete falls into the template inboard easily in the casting process, causes the cleaning difficulty.In addition, be the density that guarantees to build, in concreting process, need the Reusability vibrator to assist and make firm by ramming, for avoiding colliding reinforcing bar, template, built-in fitting etc., the degree of depth that vibrating head or vibrator insert need to be decided on building the degree of depth, for the too close position of hole to be provided, built-in fitting or reinforcing bar is arranged, need pre-establish technical measures, to guarantee smooth cloth and vibration compacting, inconvenience very.
The utility model content
It is convenient that the utility model is intended to provide a kind of demolition, installation, and mixed earth can not fall in the template, and the convenient and reliable formwork structure that vibrates.
Tunnel groove formwork for placing described in the utility model has the template that forms groove shape after installing, and template is fixed in the tunnel LIFT, and described template is the monolithic template, and the arranged on left and right sides face tilt of template from top to bottom shrinks gradually, and end face is cambered surface.
Tunnel groove formwork for placing described in the utility model, when building operation, the relevant position is put into and fixed form in LIFT, penetration concrete is to LIFT, drop on the concrete of template end face in cambered surface falls into LIFT, after concrete reaches the strength of mould stripping requirement, carry out form removal, after form removal is complete, finish and build.Its beneficial effect is: 1, all-in-one-piece template can be put into and be reclaimed in the process of construction fast, avoid repeatedly mounting or dismounting repeatedly, so that casting process fast, conveniently, and avoid concrete to fall into the template inboard and cause secondary to remove, reduce the need of work of cleaning, accelerate speed of perfusion; 2, the end face of template is cambered surface, when concrete is poured on the template, understands in cambered surface falls into LIFT, and can not be deposited in the template top, so that casting process is more smooth.
Described tunnel groove formwork for placing, the inwall of template has attached vibrator.Vibrator is made the concrete that pours into firm by ramming when building, and attached vibrator is interrupted little shaking when form removal, and template and the concrete that solidifies are got loose easily, can not produce the damage that excessive vibration causes template again.
Described tunnel groove formwork for placing, the end face of template and the junction of two sides arrange the Gai Yuan of protrusion.There is Gai Yuan the die cap both sides, so that the cover plate groove one-shot forming of groove and groove reduces workload, raise the efficiency.
Described tunnel groove formwork for placing, template are the template group that a plurality of monolithic templates form, and comprise the center die plates that template group is middle, and the side template of center die plates both sides, and the end face of side template and the junction of lateral surface arrange the Gai Yuan of protrusion.By the template group that the multiple tracks template forms, the template flange can be arranged on the edge of outermost template neatly, and the groove of all moulding can share same Ditch cover board.
Described tunnel groove formwork for placing, template is divided into two cope match-plate patterns that cooperatively interact and lower bolster by the inclined-plane that runs through the upper and lower surface of template with template.The fitting face of cope match-plate pattern and lower bolster is the inclined-plane, than vertical plane larger contact area is arranged, make to cooperate firmly, simultaneously, the inclined-plane cooperates the mutual pressure of generation and frictional force, in the time of in being fixed in groove, because of stopping of cope match-plate pattern, lower bolster can't break away from groove, during installation lower bolster must be installed first, must remove first cope match-plate pattern during dismounting, further increase fitness and the soundness of cope match-plate pattern and lower bolster.
Described tunnel groove formwork for placing, cope match-plate pattern and lower bolster are provided with the sealing plate that hides the slit, cooperation place at the end face of template and the cooperation place of bottom surface.
Described tunnel groove formwork for placing, sealing plate is respectively the gland that extended by cope match-plate pattern at end face at the lower bolster end face curved cover plate that adapts of shape with it, and holds the with it arc pallet that adapts of shape of cope match-plate pattern bottom surface in the bottom surface by what lower bolster extended.
Described tunnel groove formwork for placing is provided with weather strip between curved cover plate and the lower bolster end face; Between arc pallet and the cope match-plate pattern bottom surface weather strip is set also.Sealing plate gets up mating face seal, prevents that concrete from falling in the template fitting face, cause cleaning the increase of difficulty, and weather strip and sealing plate fitted seal further strengthened sealing effectiveness.
