Abstract
The utility model relates to a glass fiber reinforced plastic pipe, in particular to a safe and composite high strength glass fiber reinforced plastic pipe. The utility model comprises a glass fiber reinforced plastic pipe body. Both ends of the glass fiber reinforced plastic pipe are provided with a connecting inside lining. At least an overflow hole of mud is arranged on the glass fiber reinforced plastic pipe body wall. In use, the utility model penetrates into soil layers following a drill head; after withdrawing a drill stem, cement grout is perfused in the glass fiber reinforced plastic pipe body of the utility model; the cement grout is extruded from the overflow hole of the mud and enters the spongy soil layers. The safe and composite high strength glass fiber reinforced plastic pipe can longitudinally and transversally be interlaced in the spongy soil layers at definite square meter. After the cement grout is perfused, the cement grout is dispersedly extruded from the overflow hole and is distributed at an irregular net shape to fix the spongy soil layers; when excavating again, landslip accidents can be avoided.
Description
Technical field
The utility model relates to a kind of glass reinforced plastic pipe, is in particular a kind of safe composite high-strength glass reinforced plastic pipe.
Technical background
At present, in construction of tunnel, mine construction, metro construction, need at underground a large amount of excavation subterranean tunnels, because subsurface geology situation complexity, when the underground soil layer of excavation, if when running into the soft stratum of soil property, very easily cause the soil layer landslide of excavation, cause the generation of personnel casualty accidents, generation for fear of this type of accident, people emphasize safety in production, but these are passive defense mechanism when improving the exploration quality.
Summary of the invention
The purpose of this utility model is exactly that a kind of prevention Tunnel Landslide high-intensity glass reinforced plastic pipe of safety is provided for the above-mentioned defective that solves prior art.
The purpose of this utility model realizes by following technical solution.
A kind of safe composite high-strength glass reinforced plastic pipe, it includes the glass fiber reinforced plastic body, and its two ends at the glass fiber reinforced plastic body are provided with the connection interfacing, are provided with a mud overfolw hole on the glass reinforced plastic pipe body wall at least.
The purpose of this utility model also can be advanced a realization by following technology solution.
Aforesaid safe composite high-strength glass reinforced plastic pipe, the connection interfacing at wherein said glass fiber reinforced plastic body two ends is formed one by glass reinforced plastic pipe outer wall layer, metal tube lining in regular turn, constitutes public or female interfacing that connects.
Aforesaid safe composite high-strength glass reinforced plastic pipe, the external surface of wherein said metal tube lining is uneven, the glass reinforced plastic pipe outer wall layer is concavo-convex the connection with the metal liner inner room.
Aforesaid safe composite high-strength glass reinforced plastic pipe, when the connection interfacing of wherein said glass fiber reinforced plastic body is female joint, the inner surface of metal tube lining one end is a stepped surfaces, be provided with the connection thread segment in the end of stepped surfaces, the external surface of the other end of metal tube lining is a male and fomale(M﹠F), and the external surface of metal tube lining and glass reinforced plastic pipe outer wall layer connect as one.
Aforesaid safe composite high-strength glass reinforced plastic pipe, when the connection interfacing of wherein said glass fiber reinforced plastic body is male joint, the external surface of metal tube lining one end is a stepped surfaces, be provided with the connection thread segment in the end of stepped surfaces, the external surface of the other end of metal tube lining is a male and fomale(M﹠F), and the external surface of metal tube lining and glass reinforced plastic pipe outer wall layer connect as one.
Aforesaid safe composite high-strength glass reinforced plastic pipe, connection interfacing one end of wherein said glass fiber reinforced plastic body is male joint, the other end is female joint or two ends are female joint or two ends are male joint.
Advantage of the present utility model is cheap, can play reinforcing to soft stratum soil property, and pulling force surpasses 50 tons, effectively prevents the generation of landslide accident in construction of tunnel, mine construction, metro construction.
The purpose of this utility model, advantage and characteristics will illustrate by the non-limitative illustration of following preferential embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
