Abstract
The utility model relates to a tunnel construction equipment technical field specifically is a be used for tunnel concrete secondary lining to take template slip casting device. Solve two lining concrete arch tops in the current tunnel and taken off the mouth, phenomenons such as hole appear in the side wall, it uses the increase construction material to appear, labor intensity is high, safe risk is high, man -machine cooperation difficulty, low work efficiency, the long scheduling problem of construction cycle, a be used for tunnel concrete secondary lining to take template slip casting device, including the two design steel forms of just being under construction in the tunnel, design steel form top is equipped with the perpendicular injected hole that sets up of a plurality of, pre -buried on the injected hole have a RPC pipe, the inside concrete feeding steel pipe that is equipped with the level setting of design steel form, the RPC pipe is connected with the concrete feeding steel pipe, steel pipe one end is connected with the concrete feeding pump. The utility model discloses make two lining concrete construction and as an organic wholeization of slip casting construction, greatly reduced intensity of labour, practiced thrift the engineering time, guaranteed the entity engineering quality.
Description
Technical field
This utility model relates to constructing tunnel equipment technical field, specifically a kind of for tunnel concrete secondary lining band template grouting device.
Background technology
Serving as a contrast after construction completes a period of time at tunnel concrete two, because of the natural cause such as entity depression, contraction after the concrete formation that pours, tunnel form concrete two serves as a contrast easily occurs that vault comes to nothing, the phenomenons such as hole occurs between abutment wall splash guard and concrete.For improving railway, vcehicular tunnel secondary lining concrete solid quality, avoid because coming to nothing occurs in tunnel vault, the disease problems such as side wall concrete is the closest with splash guard, conventional construction method is after two lining concrete strengths reach design requirement, carries out slip casting operation.This construction method long construction period, and and uneconomical, safety.For meeting rapid construction, the job space narrow in tunnel, machinery uses difficulty, and construction material uses to be increased, and labor intensity is big, and security risk is high, and man-machine cooperation difficulty, work efficiency is low, long construction period, it is impossible to meet the prescription of current rapid construction.
Summary of the invention
In order to solve existing tunnel two, this utility model serves as a contrast that concrete vault comes to nothing, the phenomenons such as hole occurs in abutment wall, occur that construction material uses to increase, labor intensity is big, security risk is high, man-machine cooperation difficulty, the problems such as work efficiency is low, long construction period, it is provided that a kind of for tunnel concrete secondary lining band template grouting device.
This utility model takes techniques below scheme: a kind of for tunnel concrete secondary lining band template grouting device, set shaped steel formwork including tunnel two just construction, set shaped steel formwork top is provided with several vertically disposed injected holes, RPC pipe it is embedded with on injected hole, horizontally disposed concrete conveyance steel pipe it is provided with inside set shaped steel formwork, RPC pipe and concrete conveyance fastener for connection, steel pipe one end is connected with concrete pump.
The position of described RPC pipe is on the vault centrage of set shaped steel formwork, and the RPC pipe of front and back ends is respectively 1m away from set shaped steel formwork front and back ends respectively.Grouting serous fluid can be made to flow to aperture position of coming to nothing equably.
The diameter of described RPC pipe is identical with the diameter of concrete delivery pump pipe.
Treat that two lining concrete pumpings have poured, after concrete is emphasized to reach initial setting strength, before the demoulding 1 ~ 2 hour, carry out slip casting operation, injecting paste material uses high-performance high fluidity microdilatancy and the strongest slow setting filling gravity flow mortar to carry out slip casting operation, formed with two lining concrete and organically combine, solve serosity and the drawback of two linings concrete " two skins " of conventional construction method.
Compared with prior art, this utility model makes two lining concrete constructions integrated with mortar depositing construction, greatly reduces labor intensity, has saved the engineering time, it is ensured that entity project quality.Should be in the slip casting operation after railway, vcehicular tunnel two lining construction, labour force can be greatly reduced, reduce labor intensity, make tunnel concrete entity more complete, closely knit, this utility model simple in construction, make rational in infrastructure, simple to operate, can ensure that construction safety, there is certain promotional value and practical value.

Detailed description of the invention
As shown in Figure 1, 2, 3, a kind of for tunnel concrete secondary lining band template grouting device, set shaped steel formwork 1 including tunnel two just construction, set shaped steel formwork 1 top is provided with 3 vertically disposed injected holes, give on injected hole and bury the RPC pipe 2(of the long 30 ~ 40cm of φ 12.5cm (diameter with concrete delivery pump pipe etc. thick) length of RPC pipe can be determined according to two lining concrete thickness), set shaped steel formwork 1 is internal is provided with horizontally disposed concrete conveyance steel pipe 3, RPC pipe 2 is connected with concrete conveyance steel pipe 3, and steel pipe 3 one end is connected with concrete pump 4.Treat that two lining concrete pumpings have poured, after concrete is emphasized to reach initial setting strength, before the demoulding 1 ~ 2 hour, carry out slip casting operation.
The pre-buried end of described RPC pipe 2 is to be connected smooth and arranged orthogonal with two lined steel templates.
The position of described RPC pipe 2 is on the vault centrage of set shaped steel formwork 1, and the RPC pipe 2 of front and back ends is respectively 1m away from set shaped steel formwork 1 front and back ends respectively.
The diameter of described RPC pipe 2 is identical with the diameter of concrete delivery pump pipe.
