Tunnel lining trolley end head template

Abstract

The invention provides a tunnel lining trolley end head template comprising a back-pasting-type water-stop belt, a buried water-stop belt and an air bag; the tunnel lining trolley end head template ischaracterized by comprising a crochet hook, an end head template and connecting mechanisms; the end head template comprises an upper portion template and a lower portion template; one end of the buried water-stop belt is arranged between the upper portion template and the lower portion template; a groove is formed on the lower portion template; the crochet hook is provided with a sharp end bent backward and a handle part; the crochet hook is arranged in the groove and the sharp end bent backward is inserted into the buried water-stop belt; one side, away from the buried water-stop belt, of the upper portion template is vertically provided with a mounting plate; the lower portion template is provided with an arc-shaped barrier strip with a right-angled cross section, and an arc surface anda circular conical surface are formed on the arc-shaped barrier strip; and the arc surface of the arc-shaped barrier strip is matched with the a template of the tunnel lining trolley, and a casting area is formed by the circular conical surface, the end head template and the temple of the tunnel lining trolley.

Description

technical field [0001] The invention relates to the technical field of lining trolley equipment, in particular to a formwork for the end of a tunnel lining trolley. Background technique [0002] The end formwork of the existing lining trolley is composed of multiple formworks separated from the trolley. It needs to be manually installed, spliced ​​and sealed before pouring, which is not easy to disassemble. It is easy to cause damage or deformation during the process, which is not conducive to improving the pouring efficiency. In addition, due to the errors generated during operation, steps are often formed at the joints of the two sections of the second lining, which affects the pouring effect. [0003] The end formwork of the existing lining trolley does not incorporate a special waterstop fixing structure design, nor does it have the function of forming a specific joint structure on the end surface of the second lining during the pouring operation, and there is a large fu...
