Abstract
The invention discloses a construction method for repairing tunnel collapse through insertion pipe grouting. The construction method for repairing the tunnel collapse through the insertion pipe grouting comprises the following steps of: step 1, drilling operating holes: finding the portion of the tunnel collapse before construction; step 2, drilling to determine the range of the collapse; step 3, cleaning the operating holes; and step 4, inserting an insertion pipe and grouting. The construction method for repairing the tunnel collapse through the insertion pipe grouting has the advantages that the road surface and the internal rock structure of the tunnel are not damaged during tunnel collapse repairing so that the potential safety hazard of the tunnel is eliminated; the usage is safe and reliable, and the working efficiency is high; and the operability is strong, and the construction cost is reduced.
Description
Technical field
The present invention relates to a kind of job practices that the tunnel subsides of repairing, in particular, relate to a kind of intubate slip casting that does not damage tunnel structure and repair the job practices that the tunnel subsides.
Background technology
Fast development along with road construction, constructing tunnel has also been accelerated pace of construction, at present the method for tunnel construction that adopts is with forms of construction work such as blower fan boring and explosions to Mining in Rock Mass, these modes cause bigger change to rock mass structure in work progress, some change is can't observe from outward appearance, but exists crag to collapse and potential safety hazard such as landslide.After tunnel and rock mass were built moulding, tunnel outer wall and crag also had the stage of one section stable solidification, and concrete and crag are combined into one, but owing to reasons such as underground river, ground water of karst caves, subsiding of tunnel may be caused, if do not repair timely and effectively, the safety in tunnel will be influenced.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, and provide a kind of and do not damage road surface and tunnel structure, the job practices that the tunnel subsides is repaired in intubate slip casting simple to operate, safe and reliable, that construction cost is low and labour intensity is little.
In order to achieve the above object, the present invention has taked following technical scheme:
The job practices that the tunnel subsides is repaired in a kind of intubate slip casting, comprises the steps:
A, brill handle hole:
Find out the position that the tunnel subsides before the construction, bore handle hole at the position that subsides earlier, if the size that dry handle hole is observed the gap that subsides by intense light source if seepage is arranged in the handle hole, checks that by the pipe video instrument inside subsides and the situation of seepage;
Scope is determined in B, boring:
According to subside in the handle hole, the situation of seepage, near boring again origin operation hole drill hole, the size that continues to observe the gap that subsides in the handle hole again is up to the position of finding the gap that do not subside, according to the size of the area that subsides, get out the handle hole of respective numbers again;
C, cleaning operation hole:
The suction pipe of silt particle sucking pump is inserted handle hole, the mud in the handle hole, sandy soil, ponding are extracted;
D, intubate slip casting:
After finishing in the cleaning operation hole, the porous intubate of grouting is inserted in the handle hole, the porous intubate is connected with high-pressure injection pump by carrier pipe, and high-pressure injection pump applies high pressure slip casting cement is injected in porous intubate subsiding between the slit on every side.
The handle hole diameter is 80～120mm in the described steps A, and quantity is 3～6.Described high-pressure injection pump (1) operating pressure is 10MPa, and described silt particle sucking pump (4) intet diameter is not less than 50mm.Described porous intubate (3) is made of metal, inner rounded sealing taper.
Beneficial effect of the present invention: (1) reparation tunnel subsides and does not damage road surface and tunnel internal rock texture, eliminates tunnel safety hidden danger; (2) safe and reliable, high efficiency; (3) workable, reduce construction cost.
Description of drawings
Fig. 1 is the schematic diagram of work operation of the present invention;
Among the figure: high-pressure injection pump 1, carrier pipe 2, porous intubate 3, silt particle sucking pump 4, suction pipe 5.
The specific embodiment
Below in conjunction with accompanying drawing slotting the doing of the present invention described in further detail.
As shown in the figure: the device in the job practices that intubate slip casting reparation of the present invention tunnel subsides mainly is made up of high-pressure injection pump 1, carrier pipe 2, porous intubate 3, silt particle sucking pump 4, suction pipe 5.
High-pressure injection pump 1: function mainly is that the mud that will stir pressurizes, and carries to porous intubate 3 by carrier pipe 2.
Carrier pipe 2: adopt high pressure resistant rubber, internal diameter of the pipeline generally between 40mm～50mm, can bear operating pressure at 10MPa.
Porous intubate 3: intubate is that metal is made, one end is inside and outside screw thread part, be used for firmly being connected with carrier pipe 2, inner rounded sealing taper, tube head stops up when preventing 3 insertions of porous intubate, hinders intubate to spray mud, open around the intubate inner pipe wall and be evenly equipped with gunniting hole, by high-pressure injection pump 1, mud is injected in mud between porous intubate 3 slit on every side from the ejection of tube wall spray-hole.
Silt particle sucking pump 4: select a little bit smaller, the easy to operate sand pump of volume for use, intet diameter is not less than 50mm, is convenient to draw larger-diameter sandstone particle, and outlet opening is equipped with the water band, and the mud, the sandstone that extract are discharged.
Suction pipe 5: adopting internal diameter 50mm, wall thickness is the hose of 8mm, and length arranges that according to the scene end is connected on the silt particle sucking pump 4, and the other end inserts cleaning eye, by the suction of silt particle sucking pump 4, extracts bottom sediment and ponding.
The job practices that the tunnel subsides is repaired in intubate slip casting of the present invention, comprises the steps:
A, brill handle hole:
Find out the position that the tunnel subsides before the construction, bore 3 handle holes that diameter is 100mm at the position that subsides earlier, if the size that dry handle hole is observed the gap that subsides by intense light source if seepage is arranged in the handle hole, checks that by the pipe video instrument inside subsides and the situation of seepage;
Scope is determined in B, boring:
According to subside in the handle hole, the situation of seepage, near boring again origin operation hole drill hole, the size that continues to observe the gap that subsides in the handle hole again is up to the position of finding the gap that do not subside, according to the size of the area that subsides, get out the handle hole of respective numbers again;
