Abstract
The invention relates to a socket fiber reinforced composite push pipe which is used for the technical field of non-excavation construction in a municipal water supply and drainage system and can overcome the defects of easy corrosion, incapability for pressure push pipe seal and poor long-term performance of the traditional fiber reinforced composite push pipe due to the adoption of a steel lantern ring for connection. The socket fiber reinforced composite push pipe comprises a pipe body and is characterized in that the pipe body 3 is manufactured by taking resin as a basal body, quartz sand as filling and fiber and products thereof as reinforced materials, one end of the pipe body is provided with an integral socket 1 or a split type socket 8 which consists of resin fiber layers, and the other end or two ends is/are provided with a socket 2 consisting of resin fiber layers. The peripheral surface of the socket 2 is provided with a sealing trough 4, a sealing ring 5 and an injected hole are arranged in the trough, and two pipelines are connected with the sealing ring 5 through the socket 1(or 8) and the socket 2.
Description
Technical field
The present invention relates to a kind of socket fiber reinforced composite push pipe, be used for that municipal administration is given, the not excavation construction technology field of drainage system.
Background technique
Existing fibre reinforced composites push pipe joint adopts steel collar to connect, and this joint can satisfy the requirement that connects and seal in sewerage system, but has following shortcoming:
1. the joint of steel collar connection only is applicable to the sealing of low pressure pipeline, and for Pressure pipe, sealability does not reach usage requirement;
2. the fibre reinforced composites push pipe is corrosion-resistant, the life-span is long, but uses the joint of steel collar perishable, influences the working life of whole piece pipeline.
3. the steel collar of using rolls as steel plate, is connected inconvenient with the fibre reinforced composites push pipe.
Summary of the invention:
For the deficiency of problems such as the barrier performance that overcomes the steel collar joint is poor, perishable, the invention provides a kind of bear press in higher, easy to connect, socket fiber reinforced composite push pipe that long-term behaviour is excellent.
The technical solution adopted in the present invention is: a kind of socket fiber reinforced composite push pipe, comprise pipe shaft, it is characterized in that described pipe shaft 3 is is matrix with the resin, silica sand is filler, fiber and goods thereof are that reinforcing material is formed, pipe shaft one end is integrated type bellmouth 1 or the split type bellmouth 8 that pure resin fibre layer is formed, and the other end or two ends are the socket 2 that pure resin fibre layer is formed.
The side face of socket 2 is provided with seal groove 4, and seal ring 5 is installed in the groove, and to be provided with 6, two pipelines of several injected holes be to be connected with seal ring 5 by bellmouth 1 (bellmouth 8), socket 2.
The fibre reinforced composites push pipe that the present invention is connected with other modes is compared, only need during connection the socket of a socket fiber reinforced composite push pipe is inserted in the bellmouth of another root socket fiber reinforced composite push pipe, can realize being tightly connected of push pipe, easy construction; Pipe shaft 3 of the present invention, socket 2, bellmouth 1 are made for whole the winding, and bellmouth 8 is made for separately twining, and material has integrity, compares with the steel collar Placement, and long-term behaviour is stable.

Fig. 3 is the enlarged view at B place among Fig. 1;
Fig. 4 is the interconnective partial sectional view of connecting end of the present invention;
Fig. 5 is split type bellmouth;
Fig. 6 is the piping drawing that split type bellmouth connects;
Fig. 7 is split type bellmouth and socket connection diagram;
Embodiment
Described pipe shaft 3 is to be mixed by resin matrix, fibre reinforced materials and quartz sand filler to constitute; Described bellmouth 1 (or 8), socket 2 constitute by resin matrix, fiber and unidirectional fabric coiling.Side face at socket 2 is equipped with seal groove 4, seal ring 5 is installed in the groove, and is provided with several injected holes 6.
Referring to Fig. 4, when pipe shaft 1 of the present invention interconnects, be tightly connected by bellmouth 1 (or 8), socket 2 and seal ring 5 between the connecting end of two pipelines.This is connected to spigot and socket type and is tightly connected, and the sealability of connecting end is more more reliable than other Placement, and the mechanical strength height, simple to operate, convenient and quick construction need not special equipment and both can construct, and pressure testing hole 7 is set between the seal ring, after installation, can carries out pressure testing.Can make at the injected hole 6 that socket 2 is provided with between the side face of pipeline outer end and form the ring-like space of slip casting drag reduction, when construction mud go out slurry to excessive in manage, the lubricated pipe shaft outside, can reduce the surface friction drag of pipeline outer wall and soil greatly, realized the jacking distance one time, the characteristics that active well quantity is few, operating expenses is low than other tubing.Arrow among Fig. 1 is represented pipeline jacking direction in use.
