Abstract
The invention discloses a non-excavating spiral winding restoring method for underground pipelines. A new spiral pipeline is arranged in an old underground pipeline to be restored and is wound by PVC (polyvinyl chloride) strap sections into spiral, and mortar is grouted between the old underground pipeline and the new spiral pipeline. The problems of environment pollution, traffic jam and the like caused in construction and modification of urban pipe networks can be avoided, the inner wall of the restored pipeline is smooth and better in discharge capacity than the concrete pipeline before restoring, the material occupied area is small, the method is suitable for long-distance pipeline restoring, and the pipeline with water can be operated.
Description
Technical field:
The invention belongs to a kind of method of construction of urban pipe network, the non-excavation spiral of particularly a kind of under ground piping twines restorative procedure.
Background technique:
Existing urban pipe network is built and renovated, and is inevitable problem in the urban development process.In the laying of Urban Buried Pipeline Network facility, renewal process; If adopt the means of excavation comprehensively; Just not saying its huge financial expense is temporary, the influence that the environmental problem that causes thus, traffic problems, social negative effect reach resident living all will be that loss huge, that cause is difficult to the appraisal.
Therefore, take non-excavation means to solve the excavation problem in the modern pipeline network construction, the negative effect that brings with the minimizing excavation construction is the strong request of urban construction and modern society's life.Trenchless technology arises at the historic moment under such background just; The main application fields of trenchless technology: the city utility conduit system comprises: gas pipeline, water supply and sewerage pipeline, chemical pipeline, telecom conduit, heat distribution pipeline, petroleum pipeline and other underground industrial pipelines of factory etc.
Summary of the invention:
The object of the invention just is to overcome the deficiency that exists in the above-mentioned existing technology; And provide the non-excavation spiral of a kind of under ground piping to twine restorative procedure, and the problem of the environmental pollution that this method can be avoided in the construction of urban pipe network and the process that renovates, causing, traffic congestion etc., and the inner-walls of duct after repairing is smooth; Discharge capacity is better than preprosthetic concrete pipe; And the material floor space is less, is fit to the pipeline rehabilitation of long distance, and pipeline can be in the situation operation of water flowing simultaneously.
As above design; Technological scheme of the present invention is: the non-excavation spiral of a kind of under ground piping twines restorative procedure; It is characterized in that: a new pipeline of helical is set in the underground old pipeline of need reparation, and the new pipeline of this helical is to utilize the banded section bar of PVC to be wound in spiral helicine; Grouting mortar between underground old pipeline and the new pipeline of helical.
The new pipeline of above-mentioned helical is positioned at the downside of underground old pipeline.
When the new pipeline of above-mentioned helical is arranged on caliber and is the old pipeline below the 800mm, need be in new pipeline water-filling; When the new pipeline of helical is arranged on caliber and is the above old pipeline of 800mm, need in new pipeline, add blocking materials.
The jointing of above-mentioned underground old pipeline and its each arm is installed the air expansion bolt.
The present invention has following advantage and good effect:
The method of 1, twining through spiral is provided with one at old pipe interior and banded PVC section bar constantly advanced through the compacting bayonet socket forms new pipeline.After new pipeline is involved in old pipeline; Be adjacent to old tube wall through expansion; Between the space of old pipeline and new pipeline, inject the high-strength mortar liner material then, make new pipe and old tubular being integral behind this hardened material, repair pars affecta and the purpose that improves existing pipe intensity thereby reach.
2, the inner-walls of duct after the reparation is smooth, and discharge capacity is better than preprosthetic concrete pipe, and the material floor space is less, is fit to the pipeline rehabilitation of long distance, and pipeline can be in the situation operation of water flowing simultaneously.
3, carry out the construction of urban pipe network through the present invention and renovate, can avoid the problem of environmental pollution, traffic congestion.
4, the spiral winding method material therefor is the banded section bar of PVC, and low price is free from environmental pollution.
5, the banded section bar of used PVC is wrapped on the reel serially, the convenient storage and transportation.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Embodiment:
As shown in the figure: the non-excavation spiral of a kind of under ground piping twines restorative procedure; A new pipeline 2 of helical is set in the underground old pipeline 1 of need reparation; The new pipeline of this helical is that the banded section bar 3 of PVC is wrapped on the section bar capstan winch 4, and is wound in spiral helicine through Stetch Wrapping Machine 5.Grouting mortar liner between underground old pipeline and the new pipeline of helical.
Specific operation process of the present invention is:
1, investigation before the construction: before carrying out tubulation, need to remove earlier the foreign material that exist in the pipe, and wash with high pressure water.
The tubulation diameter of decision pipe: because have the crack in the pipe, burn into is damaged, even pipe joint unclamps and comes off etc., therefore, is foundation with the result of investigation in the pipe before constructing, the parameter of decision tubulation.
2, tubulation operation.According to the diameter of shape, size and the required tubulation of pipeline, utilize the banded section bar of PVC to be wound in the new pipeline of a helical.
3, when carrying out tubulation operation and mortar perfusion, can not exert an influence when in the old pipeline sewage being arranged yet.But,, thereby hinder the structural behavior that upgrades pipe for the sewage that flows in the mortar quilt that prevents to pour into and the arm that this pipe links to each other washes away.Therefore, at each arm of old pipeline and the jointing of old pipeline, need to install the air expansion bolt and flow into to stop sewage.
4, prevent that new system from moulding pipe come-up: after guaranteeing the padding hardened material, the new pipeline of spiral is positioned at the downside of existing pipe, to caliber be below the 800mm pipeline, newly manage for preventing to float, if newly do not have the sewage inflow in the pipeline, need be at water-filling in the new pipeline.To caliber is the pipeline more than the 800mm, in new pipeline, adds blocking materials to prevent its distortion and to float.
5, grouting mortar liner between underground old pipeline and the new pipeline of helical.Before this operation, seal port with sealing material earlier, and the mortar perfusing hole is set.
6, opening of arm connection mouth cut: wait after the mortar sclerosis of injection, open and cut arm connection mouth position, arm is communicated with main.The concrete cutting method of opening has two kinds:
1. through sump, stretch in the arm and blade is opened cutting the hole machine with pressurized air, make it to rotate through operation equipment and cut the hole.
2. in old pipe, use and cut the hole machine and handle.
