Description

A device for tunnel lining trolley and mould maintenance bench

technical field

The utility model relates to the field of tunnel lining construction, in particular to a device for a tunnel lining trolley and a mold maintenance platform.

Background technique

The tunnel lining trolley is a special equipment that must be used in the secondary lining of the tunnel construction process. It is used for the construction of the concrete lining of the inner wall of the tunnel. With the increasingly strict control of the construction quality standards of railway tunnel lining concrete and the gradual reduction of construction period, it is necessary to find new techniques and tooling to meet the maintenance quality requirements of lining concrete.

Problems existing in the lining construction of single-track tunnels at this stage: 1. There are serious drawbacks in traditional manual watering maintenance, such as blind spots for maintenance, unguaranteed maintenance quality, and huge waste of water resources; 2. Single-track railway tunnels have narrow construction clearances and numerous procedures. Due to the difficulty of construction organization, the existing health bench technology needs to be equipped with an additional walking system, which puts forward very strict requirements for the construction space, staffing, and water circuit modification of the single-track tunnel.

In view of the above problems, in the patent with the authorization number CN208073513U, a tunnel lining trolley with a self-contained spraying and curing system is published. The disadvantage of this patent is that only one spray pipe is arranged along the forward direction of the lining trolley, and then a nozzle is arranged at the top of the spray pipe, so as to perform water spray maintenance on the top wall of the tunnel. This will make it difficult for the water collected in the middle of the top wall of the tunnel to spread to the inner walls on both sides of the tunnel, and it is easy to cause water droplets to drip directly. However, the water spray area is mainly concentrated in the middle of the top wall of the tunnel, so the effect is still not ideal.

To this end, we propose a tunnel lining trolley and mold maintenance bench device.

Utility model content

The purpose of this utility model is to provide a device for a tunnel lining trolley to follow a mold maintenance bench, so as to solve the problem that in the prior art proposed in the above background technology, the lining trolley with its own spray system is caused by a single water spray range.

The utility model relates to a device for a tunnel lining trolley and a mold maintenance platform, which includes a lining trolley, a water supply system is arranged on the lining trolley, a support structure is fixed at the rear beam of the lining trolley, and a water supply pipeline is fixed on the support structure. , the water supply pipeline includes a water supply main pipe arranged along the traveling direction of the lining trolley and at least one water supply branch pipe which is cross-connected with the water supply main pipe and arranged laterally. Connect to the inlet end of the water supply main.

In the utility model, a brand new water supply pipeline system is provided, that is, the water supply pipeline is composed of a water supply main pipe and a water supply branch pipe, wherein the water supply main pipe is arranged along the traveling direction of the lining trolley and plays a leading role in guiding the water. The water supply branch pipe that intersects with the water supply main pipe is also set up to spray and maintain the tunnel. Because the water supply branch pipe and the water supply main pipe are set crosswise, the scope of water spraying to the two side walls of the tunnel is increased. When the water is sprayed to the top of the tunnel After the wall and the side wall, the water will flow down with the inner wall of the tunnel. In this process, the water droplets drip less from the top wall of the tunnel, and the spraying range is wider, so as to achieve the effect of spraying and curing the entire inner wall of the tunnel. In this structure, because the atomizing device has a certain spraying range, even if the water supply branch pipes are separated by a certain distance, the spraying and maintenance effect on the inner wall of the tunnel will not be affected, and the overlapping parts of spraying will be less, which effectively increases the amount of water. The utilization efficiency of resources, combined with the nozzle spraying on the top and side walls of the inner wall of the tunnel, effectively reduces the dripping of water droplets, further effectively comprehensively utilizes water resources, and has a better maintenance effect.

As a further solution of the present invention, the water supply branch pipes cross the water supply main pipe, the water supply branch pipes are evenly distributed on the water supply main pipe, and the atomizing devices are evenly distributed on the water supply branch pipes.

By standardizing the specific spatial position of the water supply branch pipe and the water supply main pipe, and optimizing the position of the atomizing device on the water supply branch pipe, the structure matching is more scientific and reasonable, so that the water spray curing effect is better, and it is conducive to the mass production of later products.

As a further solution of the present utility model: the water supply branch pipe is an upwardly convex arc structure.

The water supply branch pipe is a convex arc structure, which is more in line with the structural shape of the tunnel, thereby increasing the spraying range of the atomizing device and reducing the overlapping part of the spraying range.

As a further scheme of the present utility model: the water supply system includes a water storage tank and a booster pump, the water inlet end of the booster pump is connected to the bottom of the water storage tank through a pipeline, and the water outlet end of the booster pump is communicated with the water inlet of the water supply main pipe through a pipeline;

The support structure includes a main bracket and a branch bracket welded with the main bracket. The main bracket is fixed in the middle of the rear beam of the lining trolley. The water supply main pipe and the water supply branch pipe are respectively fixed on the main bracket and the branch bracket. The shape of the branch bracket and the water supply branch pipe match.

By describing and defining the water supply system and the supporting structure in detail, sufficient and effective support is provided for the implementation of the entire technical solution.

As a further scheme of the present invention, the main support is a truss structure, and the main support and the beam of the lining trolley are fixed by U-bolts.

In the utility model, the main support is a truss structure with high support strength, thereby providing an effective guarantee for supporting the entire water supply pipeline, and the connection method is fixed by U-shaped bolts, which is convenient for installation and disassembly.

As a further scheme of the present invention, the atomizing device adopts a reverse splash type self-locking micro-mist spray head, and the spray head is embedded on the water supply branch pipe.

The nozzle has a good spray effect, so as to meet the humidity and temperature gradient required for the lining concrete in the early stage.

The beneficial effects of the utility model are: the utility model provides a brand new water supply pipeline system, which can effectively increase the spray range on the inner wall of the tunnel and reduce the dripping of water droplets, thereby effectively increasing the amount of water on the inner wall of the tunnel. The maintenance effect can be improved, and the water resources can be fully utilized, and the utility model has a simple structure, is convenient for disassembly and assembly, and is convenient and quick in the use process.
