Abstract
A construction template for a central drainage ditch of a tunnel comprises a first template and a second template, wherein a second I-shaped steel is arranged between the first template and the second template, supporting rods are arranged at equal intervals at the upper ends of the first template and the second I-shaped steel, the second template is connected with the middle part of the second I-shaped steel through a first connecting rod, and the second template is connected with the bottom end of the second I-shaped steel through a second connecting rod; the utility model has the advantages of the template is light, and the formwork is simple, and more convenient, safe more complete, pleasing to the eye characteristics have that construction period is short, the simple operation, save material, circulated use, anti construction risk ability reinforce, the quality easily guarantees, the construction drops into economy rationally, pour the ditch more pleasing to the eye.
Description
Technical Field
The utility model belongs to the technical field of the tunnel construction equipment, concretely relates to tunnel center drainage construction template.
Background
At present, according to the development planning of the state 'five longitudinal directions and seven transverse directions', the highway construction in China enters a rapid development period, the investment of provinces in inland mountains is more and more large, the number of tunnels is large in mountainous regions, the water prevention and drainage in the tunnel construction process are particularly important, the central drainage ditch is more important, the construction process mostly adopts on-site assembly templates and concrete pouring, and the construction method has the following problems:
1. the construction period is long, a large amount of time is spent for assembling the template before and after concrete pouring each time, and the construction time and the construction progress are seriously delayed;
2. the cost is high, a large amount of manual and mechanical template assembly is needed before concrete pouring each time, the template is difficult to disassemble, the template is easy to damage, and the template needs to be frequently replaced;
3. the safety quality assurance coefficient is low, and its wholeness is difficult to guarantee to the template of on-the-spot equipment, pours the easy mould that explodes of in-process, leads to the escape canal to warp, influences its function.
SUMMERY OF THE UTILITY MODEL
The to-be-solved problem of the utility model is to overcome above-mentioned prior art not enough, aim at provides an economical reasonable, convenient to use's tunnel center escape canal construction templates.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a tunnel center escape canal steel template, includes first template and second template, be equipped with the second I-steel between first template and the second template, first template and second I-steel upper end equidistant be provided with the bracing piece, the second template is connected through the head rod with second I-steel middle part, and the second template is connected through the second connecting rod with second I-steel bottom.
Furthermore, first I-shaped steel is fixedly arranged at the top end and the lower end of the first template and the second template.
Compared with the prior art, the utility model has the advantages that:
1. the utility model has the advantages of light template, simple formwork support, and capability of hoisting by using an excavator and a loader;
2. the utility model has the advantages that in the concrete pouring process, the periphery of the central drainage ditch is vibrated more conveniently and safely;
3. the utility model discloses it can not damage the ditch inner wall to have template dismantlement process use jack, makes it more complete, pleasing to the eye.
