Specific implementation mode
We are with reference to the drawings and specific embodiments described further the utility model below.
As shown in Figs. 1-2, a kind of pump concrete slip casting template for bridge strengthening, including setting are being reinforced beam body
Plate stencil body 2 on 6；Multiple injected holes 1 for slip casting are provided on stencil body 2, injected hole connects pumping line
Discharge port；Multiple peep holes 3 are provided on stencil body 2；Further include across peep hole 3, end contact is reinforced 6 surface of beam body
Observation tube 4；Stencil body 2, which is generally located on, is reinforced 6 lower section of beam body.
Further, 4 end set of the observation tube is useful for the opening of spillage.
Further, 4 upper end of the observation tube is provided with handle 5；Handle is set on observation tube 4, after facilitating slip casting Wang Cheng
It extracts, it is reusable in next slip casting stage.
Further, the injected hole 1 is uniformly arranged in array.
Further, 1 cross arrangement of adjacent rows injected hole.
Further, peep hole 3 is both provided with the injected hole 1 of a line arrangement, between adjacent two injected hole 1.
Further, 1 shape of the injected hole is one kind round, square, in hexagonal structure.
Further, for the opening setting on the observation tube 4 in its lower end outer surface, opening is provided with multiple, opening shape
Shape is one kind in semicircle, zigzag.
In use, stencil body can be plank sheathing, steel form；The size of injected hole 1 is according to pumping line on stencil body 2
The size in road determines that shape can be one kind round, square, in hexagonal structure, can also be selected according to actual conditions
Select other structures；If 1 structure choice of injected hole is round, diameter value range is 30~200mm；For example, injected hole 1 is straight
Diameter can be 30mm, 40mm, 50mm, 70mm, 100mm, 115mm, 160mm, 180mm, 200mm etc.；Injected hole on stencil body 2
1 quantity determines that determination of amount purpose is to ensure to mix according to the size of template and the mobile performance of concrete
Solidifying soil pours closely knit；By 4 observable casting concrete of observation tube whether grout, can understand concrete in real time pours closely knit feelings
Condition；Observation tube 4 is contacted with reinforcement surface during use, can pass through gravity when concrete grout reaches beam body surface
It is flowed out from the opening of 4 end of observation tube, that is, grout occurs；Peep hole 3 be circular hole structure, diameter value range be 3~
20mm；Such as a diameter of 3mm, 4mm, 5mm, 8mm, 10mm, 15mm, 17mm, 18mm, 20mm etc. of peep hole 3；Observation tube 4 is
