Description

Technical Field

[0001] The utility model relates to the field of shield segment processing, in particular to a prefabricated shield segment finishing structure. Background Art

[0002] Currently, subway tunnels are mainly constructed using the shield method, and this method has become increasingly mature in China. Shield segment production is an indispensable part of shield construction. There are three main modes for shield segment production: traditional mode, wheel-rail mobile production line mode, and flexible production line mode. Regardless of which production mode is used, the same process is required. During normal production, the production line has a production cycle of about 4-5 minutes, that is, the production line produces one segment every 4-5 minutes. Currently, the finishing process of shield segment molds after casting in China is completed manually, which is inefficient and difficult to ensure the consistency of the finished product. Summary of the Invention

[0003] In order to use it in the processing of prefabricated shield segments and replace the manual finishing process with machinery, the utility model proposes a prefabricated shield segment finishing structure, which includes: a central beam, blocks are provided at both ends of the central beam, a plywood is provided at the lower part of the central beam, and a scraper is provided at the bottom of the plywood; the outside of the clamping block is wrapped in a rubber sleeve, the lower part of the rubber sleeve is diamond-shaped, conical or spindle-shaped, and the upper part is a handle; the clamping block, central beam and plywood are made of hard materials, and the scraper and rubber sleeve are made of elastic materials.

[0004] Preferably, the clamping block and the center beam are an integral structure or are plug-in connected, the clamping plate and the center beam are an integral structure or are fixed by bolts, and the upper part of the scraper strip is clamped into the T-shaped groove at the bottom of the clamping plate.

[0005] Preferably, the card block is embedded in a slot at the bottom of the rubber sleeve, and the shape and size of the slot match those of the card block.

[0006] Preferably, the hard material is metal or hard plastic, the elastic material is rubber or silicone or elastic polyurethane, and the surface of the rubber sleeve is frosted or orange peel texture.

[0007] Preferably, after the slot of the rubber sleeve is inserted into the card block, the thickness of the elastic material layer is greater than or equal to 1 cm.

[0008] The rubber sleeves at both ends of the plastering structure of the utility model can utilize their own elastic deformation and be installed and removed from the slide by plugging and unplugging. After the slide is installed on the improved side plate with a slide groove on the top, the slide can be pulled from one end of the shield segment to the other end by a traction device to realize mechanized plastering processing. The utility model is cleverly designed and easy to install and unload. BRIEF DESCRIPTION OF THE DRAWINGS

If the clamping block 11 and the center beam 12 are an integral structure, the clamping block 11 and the center beam 12 are injection molded or cast as a whole. If the clamping block 11 and the center beam 12 are plug-in connected, the clamping block 11 is provided with a groove for inserting the center beam 12; the splint 13 and the center beam 12 are an integral structure or fixed by bolts.
