The spliced blocking plate of a kind of Tunnel Second Lining formwork jumbo, comprise at least two stopper plate bodys in sector structure, two adjacent stopper plate body tops are connected by latch, both sides, each described stopper plate body bottom are respectively arranged with a slot, the structure of two described slots is identical, and symmetrical about stopper plate body.
Further, the both sides, top of each described stopper plate body are respectively arranged with a latch post, the central axis of two described latch post is positioned on same level line, and two adjacent latch post that two adjacent stopper plate bodys are run through on two stopper plate bodys respectively by latch connect.
Further, described stopper plate body is made up of hard plastic board or light-duty steel plate.
Circumference in the middle part of each described stopper plate body is provided with half elliptic groove, and described groove size (long × wide) is generally 10cm × 6cm, and groove is used for depositing waterstop; The both sides up and down at described groove two ends are preset with a hook respectively, for connecting the waterstop buried underground with fixing concrete structure.
The fan-shaped radian of described stopper plate body is built girth according to the disposable mould of Tunnel Second Lining and is determined, each described stopper plate body upper height D2 10cm-20cm larger than secondary lining thickness D1, i.e. D2=D1+D3,10cm≤D3≤20cm, the width on each described stopper plate body top is 80cm ~ 100cm; The height d2 5cm ~ 10cm larger than slot thickness d 1 of each described stopper plate body bottom, i.e. d2=d1+ (5cm ~ 10cm); The width of each described stopper plate body bottom equals the width of slot, is generally 60cm.
The beneficial effects of the utility model: the spliced blocking plate of Tunnel Second Lining formwork jumbo described in the utility model is mainly used in construction of tunnel, city underground engineering and urban architecture Structural Engineering, feature is applied according to the construction characteristic of Tunnel Second Lining formwork jumbo and waterstop, adjacent two stopper plate bodys adopt latch splicing, blocking plate and the connection of secondary lining formwork jumbo adopt the slot of two types to intersect and lay, and solve blocking plate and ooze slurry problem; In addition, each stopper plate body is preset the groove for depositing waterstop, hook is preset for connecting the waterstop buried underground with fixing concrete structure in groove two ends, solves the problem that waterstop is easily lost, not easily fixed.
