Description

Device for penetrating steel wire rope in small-spacing standard concrete block preformed hole

Technical Field

One or more embodiments of this description relate to hydraulic and hydroelectric engineering construction technical field, especially relate to a device that is used for downthehole wire rope of perforating of small-spacing standard concrete piece preformed hole.

Background

The concrete hinge row is used as a flexible bank protection form and is mainly applied to river regulation engineering, the concrete blocks are usually connected by steel wire ropes or steel strands, and the distance between the concrete blocks is generally 10 cm. The method mainly comprises two construction methods of 'unit prefabrication, hoisting and sinking and arranging' and 'single hole prefabrication and rope threading in a hole'. In the construction method of 'prefabricating single reserved hole and threading in hole', the generally adopted threading method mainly comprises the following steps: push-type stringing method and traction-type stringing method.

(1) The push type threading method is that the steel wire rope is directly manually conveyed into the reserved hole from the starting end. And (3) on site, feeding the steel wire rope into the reserved hole from the beginning end of the concrete block, putting the exposed head of the steel wire rope into the reserved hole of the concrete block No. 2 after the steel wire rope passes through the concrete block No. 1, and sequentially and continuously pushing the steel wire rope forwards to achieve the purpose of rope threading. The more the number of the penetrated concrete blocks is, the larger the friction force formed by the steel wire rope and the wall of the pipe with the reserved hole is, the fewer the blocks which are penetrated at one time, the more the number of the formed joints is, and the construction cost is high.

(2) The traction type threading method achieves the threading purpose by pulling from the tail end of the threading. The method is characterized in that a number 8 iron wire is pre-penetrated from the tail end of a certain number of concrete blocks to the starting end on site. Because the clearance between the diameter of the steel wire rope and the inner diameter of the concrete preformed hole is small, the connection between the iron wire and the steel wire rope can only be completed in a winding mode, and the tail end of the threading is pulled by a small-sized winch to pull the 8 # iron wire so that the steel wire rope gradually penetrates into the concrete block. The method mainly comprises the following steps that the connection between the iron wire and the steel wire rope connector is unstable, the steel wire rope connector is easy to pull off along with the increase of the number of the inserted blocks, and the pulling-off position is not fixed, and if the steel wire rope is not inserted to a preset position, secondary connection treatment is needed. The number of the blocks which are penetrated in one time is small, the construction efficiency is low, and the construction cost is high.
