Problems solved by technology

Among them, the structure of the pouring end mold has a direct impact on the construction speed and construction quality. So far, there are two common sealing modes of the second lining trolley. Plates are used for construction with wooden formwork. This method is low in material cost but high in personnel costs, time-consuming and laborious to set up the formwork, and the pouring effect is poor. In addition, a new type of end formwork, this product uses traditional steel formwork and an injection-molded structural plate for construction , the material cost is too high, the formwork saves time and effort, and the pouring effect is good

Embodiment Construction

[0024] Below in conjunction with accompanying drawing, the present invention will be further described:

[0025] Such as figure 1 with figure 2 As shown, this embodiment includes a lower formwork assembly, an upper formwork assembly, an overturning and thickness adjustment frame 11, and an elastic sealing assembly. The lower formwork assembly consists of a lower formwork 15, a lower mold fixing leg 13, a lower formwork support plate, and a lower formwork horizontal bracket. It consists of four slender through holes in the horizontal direction on the lower side of the lower template, and two lower mold support plates 12 are symmetrically arranged on the outside of the lower template. The legs 13 protrude from the lower edge of the lower template 15, and the fixed leg 13 of the lower mold extends out of the lower edge of the lower template 15. A through hole is provided in the area along the lower edge of the lower template 15. The upper end of the lower mold support plate 12 ...

Abstract

The novel secondary lining trolley end mold comprises a lower mold plate assembly, an upper mold plate assembly, an overturning and thickness adjusting frame and an elastic sealing assembly, the lower mold plate assembly is composed of a lower mold plate, lower mold fixing legs, a lower mold supporting plate and a lower mold plate transverse bracket, and the upper mold plate assembly is composed of an upper mold plate and an upper mold plate transverse bracket. The lower die plate assemblies are connected through the overturning and thickness adjusting frame. An elastic sealing assembly is arranged on the upper side of the upper die plate transverse bracket, and the elastic sealing assembly is composed of a rubber pipe, a sealing bracket, a lifting device and a guide rod. The novel secondary lining trolley end mold is suitable for tunnel pouring construction and has the advantages of being simple in structure, convenient to use, low in cost, convenient to popularize and the like.

Description

technical field [0001] The invention relates to the technical field of tunnel pouring construction, in particular to a novel end formwork of a secondary lining trolley. Background technique [0002] In the construction of the secondary lining of the tunnel, the concrete pouring of the secondary lining is a concealed project, and the design often uses reinforced concrete or plain concrete to complete the secondary lining. Concrete pouring is generally carried into the secondary lining trolley by conveying pump. The thickness of the secondary lining concrete is about 40~80cm. Whether the secondary lining concrete is filled is the key to the quality of concrete construction and plays a decisive role in the quality and safety after use. Among them, the structure of the pouring end mold has a direct impact on the construction speed and construction quality. So far, there are two common sealing modes of the second lining trolley. Plates are used for construction with wooden formw...
