Embodiment Construction

[0047] see figure 1 , Figure 2, this full-circle primary lining separated guide beam formwork platform includes a formwork, a platform and a supporting mechanism between the two. The annular backing beam 24 is connected to the inside of the formwork, and a top mold support screw disk 17 , a side mold support screw 16 and a bottom mold support screw 18 are supported between the annular back beam 24 and the stand 5 .

[0048] Its formwork includes bottom formwork 1, bottom side formwork 2, side formwork 3 and top formwork 4 which are bolted into a cylindrical shape. Example of formwork size: formwork diameter is 4.01m; 1429×864mm, 864mm sides are arc-shaped ends; panel thickness It is a 4mm steel plate, the back rib is a 4mm steel plate, the circumferential spacing of the back ribs is 216mm, and the longitudinal spacing of the back ribs is 286mm. The bottom template adopts; 1429×1372mm, and the side of 1372mm is a curved end. The bottom template is processed with exhaust holes...

Abstract

The invention relates to a linear separated guide beam template table, wherein its annular linear beam is connected to the inner side of template; the annular linear beam and the table support top template support screw disc, side template support lead screw and bottom template support lead screw between them; the table via walking device is supported on the table walking steel track above the bottom template; one table and two bottom templates are alternatively matched; the bottom template is fixed with guide beam walking steel track which supports the detachable support guide beam; the bottom of detachable support guide beam has walking wheel, while its top is detachably connected via adjustable base and table; the end of detachable support guide beam via the end base of guide beam is supported on the support concrete structure, while its one end is connected to the drawing system; another bottom template is at the concrete pouring position. And it can be used on the template table machine whose section diameter is 6-3m, with large operation space and lower cost.

Description

(1) Technical field [0001] The invention relates to a template trolley and a construction method for lining tunnels and culverts. (2) Background technology [0002] At present, needle-beam type or walk-through formwork trolleys are widely used in tunnel or tunnel lining construction at home and abroad. Although the construction technology and its degree of automation are relatively high, most of the projects suitable for construction are sections with a diameter of 6m or more. Projects below 6m still have the defects of difficult formwork cleaning, small operating space, slow disassembly and assembly speed, and high cost. (3) Contents of the invention [0003] The purpose of the present invention is to provide a full-circle one-time lining separated guide beam formwork platform and its construction method, which mainly solves the difficulty of cleaning the engineering lining construction formwork trolley with a cross-sectional diameter of 6m-3m, small operating space, slow...
