Description

Awning for pouring immersed tube roof

Technical Field

The utility model relates to the technical field of auxiliary devices for pouring immersed tube top plates, in particular to a awning for pouring immersed tube top plates.

Background

When constructing tunnels under water, a immersed tube method is mostly used for construction. The immersed tube tunnel is constructed by respectively floating a plurality of prefabricated section tunnels to a construction site on the water surface and arranging the prefabricated section tunnels one by one inside a foundation trench which is dredged.

The construction of immersed tube tunnels is generally to pour immersed tubes in a dock by using a backing pump. In the pouring process of the immersed tube top plate, rain and sun exposure are avoided as much as possible. If the situation of rain is encountered in the pouring process, the concrete can be diluted, so that the strength of the concrete is adversely affected, and then the concrete is reworked in a large amount. If the temperature of the pouring site exceeds the standard due to the fact that the sun is exposed in the pouring process, the concrete surface exposed by the sun can lose water too quickly, and therefore net-shaped cracks are generated. However, a ceiling pump is used for pouring the immersed tube top plate in the pouring site, so that it is difficult to ensure that concrete in the pouring site is not sprayed by rain or the temperature of the pouring site is too high due to sun exposure.

Disclosure of Invention

The utility model aims at: the awning for pouring the immersed tube roof is provided for solving the problems that in the prior art, a ceiling pump is used for pouring the immersed tube roof in a pouring site, and it is difficult to ensure that concrete in the pouring site is not sprayed by rain or the temperature of the concrete in the pouring site is too high due to sun exposure.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

the utility model provides a canopy that immersed tube roof was pour usefulness, includes the canopy body, and the canopy body includes waterproof tarpaulin and the support under the tarpaulin, and the canopy body is fixed in the at least one side of the truss of pulling in pouring the place through the connecting piece, and the truss of pulling is located immersed tube top and the outside mould of immersed tube is connected respectively at both ends, and the canopy body is kept away from the position to the one end of truss of pulling and is higher than the position that is close to truss one end of pulling.

The dimensions of the awning body are determined according to the actual situation and the dimensions of the awning body to be mounted are determined according to the actual situation. The attachment means include, but are not limited to, screws, pins. The positions of the awning body on any side of the opposite-pulling truss are determined according to actual pouring conditions, and the specific number of the opposite-pulling truss is determined according to actual conditions.

The opposite-pulling truss is a truss used for opposite-pulling of the side mould in a construction site. In the process of pouring the immersed tube, the shape of the immersed tube is fixed through the outer die and the inner die, and the side dies belong to the outer die and are used for pouring two side plates of the same immersed tube. The two ends of the opposite-pulling truss are respectively connected with two outer side dies on two sides of the immersed tube, and the length direction of the opposite-pulling truss is perpendicular to the length direction of the immersed tube. Because the opposite-pulling truss is usually arranged above an external mold system for pouring the immersed tube, the awning body is fixed on the opposite-pulling truss, so that the immersed tube poured under the opposite-pulling truss can be shielded from rain. The awning body comprises awning cloth and a support below the awning cloth, and the support below the awning cloth is used for supporting the awning cloth. The tarpaulin is made of waterproof material. The position of the one end that the canopy body kept away from to drawing the truss is higher than the position that is close to drawing truss one end for ponding on the canopy can flow to drawing the truss, avoids ponding on the canopy body to influence the concrete that is pouring under the canopy body. And the awning can also play a certain role in heat insulation, so that the temperature in a pouring site can be reduced as much as possible under the condition of sun exposure. The opposite-pulling truss is arranged in the pouring site, so that the possibility that the temperature in the pouring site exceeds the requirement of pouring concrete because the pouring site is airtight is reduced as much as possible.

Through setting up the canopy that this immersed tube roof was pour and is used in pouring the place, and the canopy body is kept away from the position to the one end of drawing the truss and is higher than the position to drawing truss one end to being close for can play the effect of keeping off the rain to pouring the place in the place when raining, and the tarpaulin can play certain thermal-insulated effect, it is difficult to guarantee that the concrete of pouring in the place that exists to have solved prior art is not drenched or pour the place in because of being the too high problem of sun insolation temperature, reduce as far as because raining or high temperature to the adverse effect of pouring the efficiency of place concrete quality, thereby reduced the possibility that the later stage was reworked and further promoted the pouring efficiency and the holistic efficiency of construction of concrete.
