To achieve the above object, the utility model discloses the cable penetration cannula structure of slip casting sealing, including cable, institutes
Cable to be stated to be set to across wall in casing main body, described sleeve pipe main body is embedded in advance in the wall, and described sleeve pipe main body
Both ends are flushed with the two sides of the wall respectively.
Wherein, described sleeve pipe main body is externally provided with a circle and axially vertical sealing doughnut-shaped steel plate.
Grouting Pipe, the connection of the Grouting Pipe and described sleeve pipe main body, in described sleeve pipe main body are equipped in the wall
Several axially aligned slip casting apertures are formed on wall.
If along being axially arranged with arterial highway wire brush in described sleeve pipe main body inner wall, the wire brush in a ring, around the electricity
Cable one week, the sidewall locations of the described sleeve pipe main body between wire brush described in every two were corresponding with the slip casting aperture.
Preferably, described sleeve pipe main body is made of nonmagnetic stainless steel.
Preferably, the sealing doughnut-shaped steel plate is connect with described sleeve pipe main body with welding manner.
Preferably, the Grouting Pipe is equipped with 2 groups, and Grouting Pipe described in 2 groups is along described sleeve pipe main body circumference equidistantly distributed.
It is furthermore preferred that being connected between the Grouting Pipe and described sleeve pipe main body with welding manner.
Preferably, described sleeve pipe main body inner wall is equipped with 2 to 4 slip casting apertures, in corresponding described sleeve pipe main body
Equipped with 2 to 4 road wire brushes.
The utility model has the beneficial effects that
The utility model nationality is by the slip casting aperture two sides setting wire brush on the inside of casing main body, by wire brush along internal diameter ring
Injection slurry is enclosed in the closed area that wire brush and cable are formed to the structure of distribution, stops the infiltration of underground water, realizes
Good sealing effect, and structure is simple, it is easy to accomplish, the construction work in various cable penetration walls can be widely used
In method.
Make furtherly below with reference to technical effect of the attached drawing to the design of the utility model, specific structure and generation
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
Detailed description of the invention
Fig. 1 shows the structural schematic diagram of an embodiment of the present invention.
Specific embodiment
Embodiment
As shown in Figure 1, the cable penetration cannula structure of slip casting sealing, including cable 7, cable 7 are set in casing main body 1
Across wall 4, casing main body 1 is embedded in wall in advance, and the both ends of casing main body 1 are flushed with the two sides of wall 4 respectively.
Wherein, casing main body 1 is externally provided with a circle and axially vertical sealing doughnut-shaped steel plate 2.
Grouting Pipe 3 is equipped in wall 4, the connection of Grouting Pipe 3 and casing main body 1 is formed several on 1 inner wall of casing main body
A axially aligned slip casting aperture.
If along being axially arranged with arterial highway wire brush 5 on 1 inner wall of casing main body, wire brush 5 in a ring, around cable 7 one weeks, often
The sidewall locations of casing main body 1 between two wire brushes 5 are corresponding with slip casting aperture.
The principles of the present invention are that nationality is led to by wire brush 5 is arranged in the slip casting aperture two sides of 1 inside of casing main body
It crosses wire brush 5 and injection slurry is enclosed in the closed area that wire brush and cable 7 are formed along internal diameter circumferentially distributed structure, stop
Good sealing effect is realized in the infiltration of underground water
In certain embodiments, casing main body 1 is made of nonmagnetic stainless steel.
