Abstract
The utility model relates to a tunnel center gutterway formwork. Side forms and a bottom form are combined into a whole to form the shape of a center gutterway. The width of the upper end of the formwork is larger than that of the lower end of the formwork, and the formwork is in the shape of an inverted trapezoid. The upper ends of the inner side of the whole formwork are connected through a supporting piece with the length adjustable, so that the width of the upper ends of the whole formwork can be adjusted. Lifting lugs are arranged in the whole formwork, and the whoel formwork can be lifted up and moved to a construction position with crane equipment. When used for construction, the tunnel center gutterway formwork enables the construction process to be simple and convenient, promotes working efficiency and engineering quality, and avoids defects brought by manual operation.
Description
Technical field
The utility model relates to the template that is used for the Central drain moulding in constructing tunnel.
Background technology
Large section double track tunnel adopts the design of Central drain more, and in work progress, the pouring concrete of Central drain often needs to construct separately.When the tunnel being filled the levelling construction, need to use the Central drain template that the position of Central drain is reserved.At present, the template of Central drain is all split-type structural, and it is comprised of scattered limit mould and bed die etc., needs the artificial component combination that these are scattered to be spliced into template during construction, then pours into a mould.Because the tunnel is usually all very long, often reach several kilometers even tens kilometers, and the template of Central drain often only there are several meters, 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 easily produces the defectives such as gap and dislocation between plate and plate; The integral linear of the Central drain of cast is difficult to control, and affects outward appearance.In addition, the combination of template is also higher to operating personnel's technical requirements; In addition, in casting process, concrete easily falls into the template inboard, causes the cleaning difficulty.
The utility model content
The utility model is intended to provide a kind of all-in-one-piece tunnel Central drain template, with the construction in center of reduction ditch, improves efficiency of construction and construction quality.
Tunnel described in the utility model Central drain template comprises left and right two limit moulds and bed die, and two limit moulds spacing is from the bottom up widened gradually, and bottom and the bed die of two limit moulds are connected and fixed, and the top of two limit moulds connects by the adjustable support member of length.
when carrying out tunnel Central drain construction, measure unwrapping wire to determine the position of template placement, after treating location positioning, using lifting appliance template to be sling and move to the tram positions, after Template Location, the length of regulating support member makes it to reach the design width, regulate the preparation of namely completing template after complete, to the LIFT fluid concrete, until concrete reaches the cast height, after reaching the strength of mould stripping requirement, concrete carries out form removal, regulating support member when form removal reduces the spacing of mould upper end, two limits, make template break away from concrete surface, the template of slinging to the next position continues operation, repeat above step and complete construction.Its beneficial effect is: 1, all-in-one-piece formwork rigidity is large, and is sturdy and durable; 2, template can be put into fast and reclaim in the process of construction, avoids mounting or dismounting repeatedly repeatedly, makes work progress fast, conveniently; 3, avoid concrete to fall into the template inboard and cause secondary to remove, reduce the need of work of cleaning, accelerate speed of application; 4, the width of template upper end is larger than the lower end, is the inverted trapezoidal shape, is convenient to the operation of formwork erection and form removal; The width of 5, the support member adjustable length of template inner top side, and then adjusting template upper end can be regulated the location during formwork erection, and template and concrete surface are broken away from, and makes simple to operation; 6, by the lifting appliance moving die plate, realize mechanized operation, many defectives of avoiding manually-operated to bring, and reduce constructor's technical requirements.
Described tunnel Central drain template, the inner surface of Bian Mo and bed die is respectively limit mould bases, bed die frame, and external surface is panel, and mould bases is fixedly connected with panel respectively.Its beneficial effect is: panel material is drawn materials easily, can directly use the building site material to make, and does not need complicated processing technology; Panel is changed convenient, reduces the replacing difficulty that causes because of damage.
Described tunnel Central drain template, support member is the adjustable screw rod of length, determines the width of template by the length of adjustable screw bar, during the demoulding, can regulate screw rod and shrink, the distortion of mould top, both sides is drawn in, break away from the mixed earth of both sides, thereby can realize easily the demoulding.
Described support member also can be hydraulic stem.

The specific embodiment
Embodiment one, as shown in Figure 1.
Tunnel described in the utility model Central drain template, comprise left and right two limit moulds 1 and bed die 2, two limit moulds 1 spacing is from the bottom up widened gradually, and the bottom of two limit moulds 1 and bed die 2 are connected and fixed, and the top of two limit moulds 1 connects by the adjustable support member 3 of length.
Embodiment two, as shown in Fig. 2,3,4.
The inner surface of described limit mould 1 and bed die 2 is respectively limit mould bases 11, bed die frame 21, external surface is panel 12,22, limit mould bases 11, bed die frame 21 are fixedly connected with panel 12,22 respectively, the inner top side of limit mould bases 11 is connected with holder 4, the two ends of support member 3 holder 4 relative with two respectively are hinged, the upper end of bed die frame 21 is equipped with the relative hanger 5 of a plurality of hangers 5, two along bed die frame 21 Central Symmetries.All the other are identical with embodiment one.
