Description

Technical Field

[0001] The utility model relates to the technical field of trackless slip forms for concrete face rockfill dams, and particularly relates to a trackless slip form for a concrete face rockfill dam. Background Technique

[0002] As is well known, in the construction of dam concrete, it is necessary to carry out layered pouring. During the pouring process, generally, a winch is used to tow the support, and after pouring, the workers on the support level it. In order to prevent the support from shifting, it is necessary to install tracks for guiding. Among them, the "trackless slip form for the overflow surface of a concrete dam" disclosed in the patent application number "CN201320762408.3" is also an increasingly mature technology. The sliding frame slides on the already poured concrete surface and the sample frame, without the need for a special slip form track. At the same time, a guide wheel with a towing rope is arranged on the support column, and the truss includes a counterweight block, which can make the panel closely adhere to the concrete surface and slide along the sample frame to ensure the body dimensions of the overflow surface. However, the steel cable wound during the winding process of the above equipment is prone to entanglement after winding, is not easy to separate and sort out after winding, and is not convenient to adjust the position of the steel cable. Therefore, we propose a convenient-to-use trackless slip form for a concrete face rockfill dam to solve the above problems. Content of the Utility Model
