Description

SUPPORT APPARATUS FOR CASTING CONCRETE IN THE SLOPE OF A EMBANKMENT}

The present invention relates to a device for supporting concrete placing works on dam surface, and in particular, a support truck for transporting various materials for supporting concrete pouring work or supporting auxiliary work, and a transport truck for transporting and transporting the support car. The present invention relates to a dam front concrete placing work support device provided with a mounting means so that it can be easily mounted when transferring a supporting vehicle to another work section so that the whole process of the placing work can proceed smoothly.

In general, when placing concrete on the dam's surface, concrete is installed after conventional formwork is installed, but in this case, there is a problem that the air is long and there is a problem of safety accident because the work must be performed on a steep slope. There was this.

Therefore, there is a concrete pouring method using the slip form (Slip Form) as a method developed to improve these problems.

In the concrete pouring method using slip foam, a pair of guide rails are installed on the inclined surface such as a dam at regular intervals up and down, and a slip foam is installed to drive the guide rail so that a section of a certain height from the bottom of the inclined surface is provided. After the concrete is poured in, and after a certain period of time, the concrete is poured to the top of the dam by pulling up the slip form along the guide rail and placing the concrete in the next section.

As a concrete pouring method using such a slip foam is known as Korean Patent No. 43256.

However, in this patent method, various materials such as reinforcing bars, chutes, guide rails, cement, mortar, etc., which are needed for the pouring work performed by the slip foam packing machine are loaded and transported in the slip foam packing machine which performs the pouring work. In order to carry out various additional work on slip foam packing machine, various operations such as reinforcing bar reinforcement work, chute installation work, and guide rail installation work are performed by using slip packing machine to smoothly pour the work. There was a problem that the work time and costs are increased.

The present invention was devised to solve the above-mentioned conventional defects and problems, and install a support vehicle for transporting various materials for concrete placement or supporting an auxiliary work, and a transport vehicle for towing and transporting the support vehicle. The purpose of the present invention is to provide a dam-front concrete placing work support device which is equipped with a mounting means so that it can be easily mounted when transferring the supporting car to another work section. have.
