Abstract
The invention discloses a processing technique and a construction system of a steel framework plastic composite pipe in the non-digging construction. The construction system comprises a pipeline formed by connecting a plurality of sections of steel framework plastic composite pipes, wherein two ends of the pipeline are closed; any end of the two closed ends of the pipeline is opened and is connected with a barometer and an air compressor through a gas transmission pipe; and an air inlet valve is arranged on the gas transmission pipe. According to the invention, gas inside the pipeline is pressurized, thus the non-deformability of the steel framework plastic composite pipe in the pulling process is improved, further the deformation of the pipeline during pulling in the non-digging construction is avoided, the adverse influence caused by the steel plastic composite structure and an electric smelting connector of the pipeline due to the deformation of the pipeline is avoided, and the quality of a pipeline project can be effectively protected. With the improvement of the pipeline on the non-deformability, the pipeline can be pulled by using a greater force, the pulling speed of the pipeline is increased, the construction efficiency is improved, and the construction cost is reduced.
Description
Technical field
The present invention relates to the ground crossing construction worker method of burying of steel skeleton plastic clad pipe, specifically be meant treatment process and the construction system thereof of a kind of steel skeleton plastic clad pipe in non-excavating construction (promptly burying ground crossing construction or underground crossing construction).
Background technique
Steel skeleton plastic clad pipe is as the novel pipeline of energy-saving and environmental protection; Because of its excellent physical property and good cost performance apply to urban water supply pipe network and the construction of gas supply pipe net widely; In pipeline network construction is built; Often, can not or be not easy to carry out the excavation of pipe laying groove, need to adopt trenchless technology to construct because of the stopping of road, building or river etc.
Steel skeleton plastic clad pipe adopts the trombone slide method to carry out non-excavating construction usually, adopts the length of pipeline of non-excavating construction not wait from tens meters to hundreds of rice generally speaking, need a root tubing be connected into a pipeline and carry out disposable integral pulling construction; Therefore in the pulling process, can produce very big frictional force between pipeline and the soil,, need to use bigger pulling force could tubing be spurred owing to be location poor for some soil properties, that be difficult for pore-forming; Because steel skeleton plastic clad pipe is to adopt steel plastic composite structure; Tube wall thickness is thinner, and ring stiffness is lower, tubing easy deformation when pulling; Particularly the large-diameter steel frame plastic composite pipe is when non-excavating construction is used; Pipe deforming is serious, possibly cause the steel plastic composite structure of pipeline to be destroyed or to influence the intensity of pipe coupling, thereby the quality of pipework is impacted.
In addition, for burying in the ground crossing construction process, therefore the going into the location and pass the distortion that there is several angle in ground segment of pipeline make the pipeline generation quality problems at this place equally.
Summary of the invention
First purpose of the present invention is in order to overcome the shortcoming and defect that existing technology exists, and the treatment process of a kind of steel skeleton plastic clad pipe in non-excavating construction is provided.
Another object of the present invention provides a kind of non-excavating construction system of steel skeleton plastic clad pipe.
For realizing first purpose of the present invention, technological scheme of the present invention is to may further comprise the steps the pipeline that (1) connects into the multistage steel skeleton plastic clad pipe length that non-excavating construction requires; The further setting of this step (1) is that described multistage steel skeleton plastic clad pipe adopts electric melting pipe fittings to connect.
(2) with the closed at both ends of pipeline, and in arbitrary end perforate of two closed ends of pipeline, and utilize air compressor to pass through position of opening gas transmission pressurization in pipeline, make manifold pressure reach 0.2-0.3MPa after, stop pressurization, maintain constant pressure in the pipeline.It is to adopt electric melting pipe fittings to weld a plastics pipe plug respectively at the two ends of pipeline that this step (2) further is provided with, and constitutes the pipeline closed at both ends.
Second purpose of the present invention realizes through following technological scheme; Include the pipeline that is formed by connecting the multistage steel skeleton plastic clad pipe; The closed at both ends of pipeline; And arbitrary end perforate of two closed ends of pipeline, and be connected with barometer and air compressor through pneumatic tube, this pneumatic tube is provided with suction valve.
Further being provided with is that described multistage steel skeleton plastic clad pipe is welded to connect into pipeline through electric melting pipe fittings.
Further being provided with is to adopt electric melting pipe fittings to weld a plastics pipe plug respectively at the two ends of pipeline, constitutes the pipeline closed at both ends.
Advantage of the present invention and good effect:
The present invention adopts the pipe interior gas pressurized; Improved the non-deformability of steel skeleton plastic clad pipe road in the pulling process; When being pulled, pipeline do not produce distortion in non-excavating construction; Make the steel plastic composite structure and the electric smelting jointing of pipeline can not protect the quality of pipework effectively because of pipe deforming produces harmful effect.The raising of pipeline non-deformability can use bigger power to pull pipeline, accelerates the speed that pipeline pulls, and improves efficiency of construction, reduces construction cost.
The present invention adopts gas pressurized, and the weight increasing amount of pipeline is little, and is little to the influence of construction, can not increase difficulty of construction because of pipeline weight.
Below in conjunction with Figure of description and embodiment the present invention is done further introduction.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure, 1 steel skeleton plastic clad pipe, 2 electric melting pipe fittings, 3 plastics pipe plugs, 4 suction tude, 5 air compressors, 6 barometers, 7 suction valves.
Embodiment
Through embodiment the present invention is carried out concrete description below; Only be used for the present invention is further specified; Can not be interpreted as the qualification to protection domain of the present invention, the technician in this field can make some nonessential improvement and adjustment to the present invention according to the content of foregoing invention.
The treatment process of steel skeleton plastic clad pipe provided by the invention in non-excavating construction; Include steel skeleton plastic clad pipe 1 and electric melting pipe fittings 2; Use electric melting pipe fittings 2 that the steel skeleton plastic clad pipe 1 of a root is connected into a pipeline; Length of pipeline is confirmed according to the length that non-excavating construction need lay, and uses plastics pipe plug 3 in electric melting pipe fittings 2 welding respectively at the two ends of pipeline then, opens a hole on the plastics pipe plug 3 at one end and connects upward suction tude 4; Suction tude 4 the other ends connect goes up air compressor 5; Be used in compound pipe, pressurizeing, the barometer 6 that is used to measure gas pressure size in the steel skeleton plastic clad pipe 1 is installed on suction tude 4, between air compressor 5 and barometer 6, suction valve 7 is installed.
In the implementation process of the present invention, according to above-mentioned equipment is installed after, open suction valve 7; Starting air compressor 5 pressurizes in pipeline; According to the pressure-display on the barometer 6, the pipeline internal pressure stops air compressor 5 and closes suction valve 7 when reaching 0.2-0.3Mpa, stops pressurization; And air compressor 5 pulled down from suction tude 4; Connect non-excavation equipment from the pipeline the other end and both can carry out the pipeline non-excavating construction, because of pipe interior has the support of gas pressure, pipeline can not produce distortion in the pulling process.
