Description
Technical field
The utility model relates to a kind of tail sealing grouting device of shield machine.
Background technology
Along with the rise of Chinese city subway construction, shield-tunneling construction affects the characteristics such as little, that driving speed is fast, ground settlement is little with it to ground and underground environment, is used more and more at home.Use shield-tunneling construction at Urban Underground, for controlling ground settlement, tail sealing grouting device is essential with the grouting device that prevents the grouting at the tail of the shield machine backflow.Existing grouting device is installed comparatively complicated, after line rivet welding welding screw in factory, more on-site the grouting device is mounted with on shield tail housing.Because the reason of shield stern construction, assembling grouting plate on the building site, required number of spare parts is huge and model is different, and cost and difficulty are all larger; Also easily distortion of shield tail and welding screw in transportation simultaneously, if the situation of distortion occurs, the installation of grouting plate is coarse, and precision is not high, and application life is shorter.
The utility model content
The utility model purpose is to provide a kind of convenient installation, and the tail sealing grouting device of saving raw material and having simultaneously sealing and grouting binomial function is to solve the problems of the technologies described above.
For achieving the above object, the utility model provides a kind of tail sealing grouting device, comprises bracing frame, grouting plate, wire brush; The support frame as described above longitudinal section is the round rectangle of an end opening; The grouting front edge of board is placed in the outside of bracing frame, and its tail end is positioned at above water, with the angle of horizontal plane be 10 to 90 degree; The wire brush front end is placed in bracing frame inside, and its tail end is positioned at below horizontal plane, with the angle of horizontal direction be 10 to 90 degree; The wire brush front end is placed in bracing frame inside, receives unsettled in the other end; The front end of described grouting plate is connected by linkage with the front end of wire brush and bracing frame.
Preferably, a side of support frame as described above is the arc-shaped side that extends along the outward opening side, and the front end of grouting plate is placed on arc-shaped side.
Preferentially, described linkage is rivet.
The utlity model has following beneficial effect: 1, the grouting plate is directly installed on bracing frame, fixedly grouting device is installed separately on shield tail housing compared to existing technology, this device has been simplified the extensive work of assembling shield tail grouting system, reduce part kind and quantity, saved manufacturing and construction cost; 2, this device can weld assembly unit on shield tail housing circumference, is not subjected to the impact of shield tail distortion, and installation accuracy is high, and is reliable and stable, long service life.3, at the shield tail of existing shield machine, only last row's tail sealing need to be replaced with the function that this device can reach tail sealing and grouting simultaneously, install simple and saved raw material.
Except purpose described above, feature and advantage, the utility model also has other purpose, feature and advantage.The below is described in further detail the utility model with reference to figure.
Description of drawings

Fig. 4 is the overall schematic after the preferred embodiment installation;
Fig. 5 is the work schematic diagram of preferred embodiment.
Description of symbols: 1, grouting plate; 2, bracing frame; 3, wire brush; 4, rivet; 5, shield tail housing.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but the utility model can be implemented according to the multitude of different ways that claim limits and covers.
Referring to Fig. 1, Fig. 2 and Fig. 3, a kind of tail sealing grouting device comprises bracing frame 2, grouting plate 1, wire brush 3; Bracing frame 2 longitudinal sections are the round rectangle of an end opening; Grouting plate 1 front end is placed in the outside of bracing frame 2, and its tail end is positioned at above water, with the angle of horizontal plane be 10 to 90 degree; Described wire brush 3 front ends are placed in bracing frame 2 inside, and its tail end is positioned at below horizontal plane, with the angle of horizontal direction be 10 to 90 degree; Wire brush 3 front ends are placed in bracing frame 2 inside, and the other end is unsettled; The front end of grouting plate 1 is connected by linkage with front end and the bracing frame 2 of wire brush 3.
During use, bracing frame 2 is welded on the step of shield tail housing 5 reservations, this device is close to shield tail housing close-packed arrays on shield tail circumferencial direction becomes a whole circle.Under the squeezing action of tunnel inner wall, grouting plate 1 is pressed on tunnel inner wall tightly, and the wing plate of adjacent grouting plate 1 is overlapped, forms a circle sealing, has reached the purpose of sealing; Again shield body excavation zone and grouting at the tail of the shield machine zone are separated simultaneously, it is regional that the grouting at the tail of the shield machine of filling the excavation gap can not be back to shield body front portion or cutterhead excavation, reached the purpose of grouting.Grouting plate 1 is directly installed on bracing frame 2, fixedly grouting device is installed separately in compared to existing technology on shield tail housing 5, and this device has been simplified the extensive work of assembling shield tail grouting system, has reduced part kind and quantity, has saved manufacturing and construction cost; This device can weld assembly unit on shield tail housing 5 circumference, be not subjected to the impact of shield tail distortion, and installation accuracy is high, and is reliable and stable, long service life.
At the shield tail of existing shield machine, only last row's tail sealing need to be replaced with the function that this device can reach tail sealing and grouting simultaneously, install simple and saved raw material.
Further improvement as above-described embodiment, one side of bracing frame 2 is the arc-shaped side that extends along the outward opening side, the front end of grouting plate 1 is placed on arc-shaped side, and rear end bending outwardly is unsettled, and the front end of grouting plate 1 is connected by rivet 4 with front end and the bracing frame 2 of wire brush 3.
The above is only preferred embodiment of the present utility model, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
