Abstract

The invention belongs to the field of tunnel engineering secondary linings, and particularly relates to a tunnel secondary lining width adjustable concrete end mold and an adjusting method thereof. The end mold comprises an inner side end mold and an outer side end mold which are mutually hinged, the inner side end mold is connected to a trolley mold, the outer side end mold is slidably connected to an extending plate, and the relative sliding direction is in the radius direction of the outer side end mold fan shape. Aiming at the problem in the prior art that a steel end mold cannot extend randomly to fix a back adhered water stop belt, as a result, the water stop belt cannot exert the effect of stopping water, the width of the end mold can be adjusted according to the width between a trolley mold and a primary support surface to effectively fix the back adhered water stop belt, and a required waterproof effect is achieved. Compared with the prior art, the problem of fixing the back adhered water stop belt is solved, and thus the reliability of the construction quality is guaranteed. The work efficiency is improved, and the construction period is drastically shortened. The material waste is avoided, and the construction cost is saved. The construction environment safety is improved.

Description

technical field [0001] The invention belongs to the technical field of secondary lining of tunnel engineering, and in particular relates to a concrete end form with adjustable width of secondary lining of tunnel and an adjusting method thereof. Background technique [0002] In tunnel engineering, surrounding rock support is generally divided into primary support and secondary lining. Secondary lining refers to the inner lining built with concrete and other materials under the condition of the initial support of the tunnel, so as to achieve reinforcement and support, optimize the route, install drainage system, beautify the appearance, and facilitate the installation of communication, lighting and monitoring and other facilities to meet the requirements of modern tunnel construction. [0003] The secondary lining of the tunnel is generally a concrete or reinforced concrete structure. The lining trolley is a special equipment that must be used in the secondary lining during ...
