Utility model content
Technical problem to be solved in the utility model is to provide a kind of energy when gas tube passes through body of wall
Enough protect gas tube not by the protection device of body of wall extruding.
This utility model is to solve above-mentioned technical problem by the following technical programs：
A kind of gas tube resistance to compression pillar, including inner protective tube and outer protection tube；
The inner protective tube includes two identical semicircular ring hollow cylinders, fills out in the middle of the housing of the semicircular ring hollow cylinder
Filled with injecting paste material, two semicircular ring hollow cylinders constitute the inner protective tube of an annular；
The outer protection tube includes two identical hollow cylinders, and the hollow cylinder is provided centrally with semicircular groove,
The radius of the groove is equal with the external diameter of the semicircular ring hollow cylinder, and the semicircular ring hollow cylinder can be nested in described
In the middle of groove；Two hollow cylinders constitute an outer protection tube；Injecting paste material is filled with the hollow cylinder housing.
Preferably, the injecting paste material is Ma Lisan.
The internal diameter of preferably described semicircular ring hollow cylinder is equal with the radius of gas tube, and gas tube can be contained in
In the semicircular ring hollow cylinder.
Preferably, the thickness of the semicircular ring hollow cylinder is 100mm～200mm.
Preferably, an injection orifice and an aerofluxuss are each provided with the semicircular ring hollow cylinder and the hollow cylinder
Hole, is respectively intended to inject Ma Lisan and outside air-discharging.
Preferably, the injection orifice and steam vent on the semicircular ring hollow cylinder is in approximately the same plane；The open tubular column
Injection orifice and steam vent on body in approximately the same plane, in preventing injection process, discharge from another aperture by Ma Lisan.
Preferably, described semicircular ring hollow cylinder one end is provided with the stopping means beyond external cylindrical surface, prevents in needs
When dragging gas tube, the inner protective tube is skidded off from the outer protection tube.
Preferably, the outer protection tube is rectangle perpendicular to the cross section periphery of axis.
The utility model has the advantage of：This utility model processing is simple, is easy to operation；Using filling horse in hollow body
Beautiful scattered mode buffers body of wall pressure, make use of the compressive property of body itself, and Ma Lisan to be filled out by high-pressure extrusion automatic expansion
The characteristic in crack is filled, comprcssive strength is high, is effectively guaranteed the safety of the pipeline through the resistance to compression pillar；While the outer shield
The shape of pipe can be arranged according to body of wall situation, convenient use.
