Description

A kind of method for maintaining for complex condition deep-buried pipeline
Technical field
The present invention relates to the technical field of construction of deep-buried pipeline maintenance, especially a kind of to be used for complex condition deep-buried pipeline Method for maintaining.
Background technique
" zip mode " construction of pipeline is all the time by denouncing in city, when, but the crowd is dense, closes on and builds in traffic When building the deep-buried pipeline local failure of the complex conditions such as object, especially buried depth greater than 4m, open-cut is also carried out, is needed a large amount of Construction protection measure, not only increase construction risk and project cost, also result in environmental pollution.
Summary of the invention
The purpose of the present invention is provide a kind of for complex condition deep-buried pipeline according to above-mentioned the deficiencies in the prior art Method for maintaining, by using spinning steel sleeve to deep-buried pipeline carry out fixed point cutting repair, realize " minimally-invasive " maintenance, subtract Small scope of construction item and cost reduce construction risk.
The object of the invention realization is completed by following technical scheme:
A kind of method for maintaining for complex condition deep-buried pipeline, it is characterised in that:The method for maintaining includes at least Following steps:The spinning steel sleeve at the local failure of deep-buried pipeline, using the steel sleeve to the part of the deep-buried pipeline It is cut at destruction;It equipment is grabbed using punching takes and screw out the steel sleeve to the top of the deep-buried pipeline upwards after soil;? Assembled retaining wall is transferred in the steel sleeve, then pipeline is subjected to reinforcement recovery.
After cutting at local failure of the steel sleeve to the deep-buried pipeline, the lower section assembled shield Wall, the assembled retaining wall is to progress enclosing at the local failure of the deep-buried pipeline.
Positioning steel pile casting is buried at the local failure of the deep-buried pipeline, the steel sleeve is from the positioning steel pile casting Spinning.
The caliber of the steel sleeve is at least not less than the area at the local failure of the deep-buried pipeline.
Jagged cutter head is inlayed in the bottom of the steel sleeve.
It is an advantage of the invention that:On construction ground in the case where anxiety, avoids " zip mode " construction and urban road is handed over Logical influence, and save a large amount of constructions and go along with sb. to guard him expense;Construction technology is mature, and occupied ground is small, environmental pollution is small, has very big Engineering popularization and application foreground.
Detailed description of the invention
Fig. 1 is construction process elevation of the invention;
Fig. 2 is construction process plan view of the invention.
Specific embodiment
Feature of present invention and other correlated characteristics are described in further detail by embodiment below in conjunction with attached drawing, so as to In the understanding of technical staff of the same trade:
As shown in Figs. 1-2,1-4 is marked to be expressed as in figure:Steel sleeve 1, deep-buried pipeline 2, native 3, assembled retaining wall 4.
Embodiment:It is used for for the method for maintaining of complex condition deep-buried pipeline to generation local failure in the present embodiment Deep-buried pipeline repairs, and deep-buried pipeline is located at the complex conditions such as soft clay area, Nearby Structure.
Method for maintaining includes the following steps:
1)Preparation of construction
Including organizing, arranging construction human eye, goods and materials, material, equipment prepare, and construction site arrangement, mechanical equipment is assembled, peace Entirely, it all preparations before construction such as confides a technological secret.
2)It measures deep-buried pipeline and destroys dot center, embedded positioning steel pile casting
According to field lofting coordinate, the i.e. embedded positioning steel pile casting before hardened ground.Position the burial place position of steel pile casting Top at deep-buried pipeline local failure, for playing the role of positioning to subsequent steel sleeve circumgyration incision drilling.
3)Full-rotating drill positioning
Roadbed paving plate, full-rotating drill telephone-moving positioning, adjusts the horizontal and vertical degree of drilling machine, the steel bushing for configuring drilling machine Tube hub is consistent with the positioning steel pile casting center buried.
4)Steel sleeve circumgyration incision cutting drilling, using punching crawl soil
Full-rotating drill drives steel sleeve to be rotated down cutting cutting drilling from the center of positioning steel pile casting and sinks to.Such as In Fig. 1 and Fig. 2(a)Shown, the drilling depth of steel sleeve 1 is until it is located at 2 or less 0.5m of deep-buried pipeline.In steel sleeve 1 During rotary drilling, to being cut at the local failure of deep-buried pipeline 2.As shown in figure 1(a)Shown, steel sleeve 1 is boring It grabs equipment using punching into soil 3 in the process to take out, state after taking-up is as shown in figure 1(b)It is shown.
5)The decentralization of assembled retaining wall
As shown in figure 1(c)It is shown, steel sleeve 1 is threaded to the pipeline top 0.15m of deep-buried pipeline 2 upwards, for subsequent decentralization 4 reserved space of assembled retaining wall.Assembled retaining wall 4 is transferred in steel sleeve 1, assembled retaining wall forms the enclosing area of maintenance Domain, the i.e. soil body of 2 surrounding of enclosing deep-buried pipeline are located at the region of 4 enclosings of assembled retaining wall at the local failure being removed It is interior.
6)Spreading reinforcement recovery is carried out to deep-buried pipeline 2 in the enclosing region of assembled retaining wall 4.
7)As shown in figure 1(d)With(e)It is shown, assembled retaining wall 4 is taken out out of steel sleeve 1, backfill in steel sleeve 1, it Steel sleeve 1 is screwed out afterwards.
The present embodiment is in the specific implementation:In order to improve the stock-removing efficiency and drilling effect of steel sleeve, at the bottom of steel sleeve End can inlay jagged cutter head, during the rotary drilling of steel sleeve, cutter head under the driving of full-rotating drill with Steel sleeve rotation, cuts the soil body in drilling process, while cutting to deep-buried pipeline.Titanium alloy can be selected in cutter head It is made.
In Fig. 2(a),(b),(c)Or(d)Shown, the caliber of steel sleeve 1 is at least not less than the part of deep-buried pipeline 2 Area at destruction avoids cutting off not clean feelings to guarantee to be cut completely at the local failure on deep-buried pipeline 2 by steel sleeve 1 Condition occurs.
Although above embodiments are elaborated referring to conception and embodiment of the attached drawing to the object of the invention, this Field those of ordinary skill will recognize, still can be right in the case where no disengaging claim limits the precondition of range The present invention makes various modifications and variations, shape, size such as steel sleeve 1;The structure etc. of assembled retaining wall 4, thus it is different herein One repeats.
