Abstract
The construction process includes four steps of digging an operating pit and a receiving pit, drilling the guide hole to the receiving pit with a drilling machine installed inside the operating pit, reaming from the receiving pit to the operating pit to form drawing hole by the reamer installed onto the drilling tool and threading steel cable, and drawing the steel cable and thus the casing with a dragger from the operating pit to the receiving pit. The process may be applied to drawing casing through drilled hole in various geologic conditions and has the advantages of no need of large machine, relatively lower engineering amount, low cost and high engineering quality.
Description
The present invention relates to a kind of sleeve pipe construction method for crossing.
Prior art sleeve pipe construction method for crossing push pipe commonly used passes through method.Construction by pipeline jacking method must use push-bench, and machinery equipment is huge, cost an arm and a leg, the construction cost height must excavate the large operation hole, also propping up on the wall of hole to the end, hole under the machinery, pass through with push-bench pushing tow sleeve pipe, in most cases, push pipe passes through method and must cooperate with hand digging simultaneously, use hand digging at the sleeve pipe front end, push pipe advances while excavating, until with the sleeve pipe pushing tow to the precalculated position, a large amount of manpowers had both been consumed, the safety inadequately of constructing also., and in the construction by pipeline jacking method,, cause sleeve pipe rhegma, distortion easily because jacking force is huge, and meeting the complicated geological situation, also can make by the sleeve pipe of pushing tow to sink to departing from projected route, influence construction quality.
The object of the present invention is to provide a kind of construction method of drawing casing through drilled hole.
The object of the present invention is achieved like this, and a kind of construction method of drawing casing through drilled hole comprises following construction sequence:
A. dredge operation hole and reception are cheated:
Excavate the operation hole at top and the reception hole of terminal at the construction site two ends that sleeve pipe passes through;
B. bore pilot hole:
In bottom, operation hole driling machine is installed, is started driling machine, get out the pilot hole of a diameter, the through hole that receives less than casing diameter with the degree of depth and the direction of drilling tool along predetermined construction access road;
C. cheat the direction reaming and lead back haulage cable to operation from receiving the hole along pilot hole:
In receiving the hole, the reamer that the external diameter that haulage cable top is housed is slightly larger than the cover external diameter of pipe is contained on the drilling tool of driling machine, starting driling machine makes reamer return to rotation reaming limit, direction limit, operation hole from receiving the hole along pilot hole, pilot hole is expanded as the towing pad of slightly larger in diameter in the cover external diameter of pipe, and haulage cable top is moved in the operation hole;
D. drag spring thimble
In operation hole, withdraw driling machine, and place and be pulled the sleeve pipe that passes through; Receiving bottom, hole installation tractor; The top that leads toward the haulage cable in operation hole is contained in and will be pulled the front end of the sleeve pipe that passes through, the terminal of haulage cable is contained on the tractor; Start tractor, arrive the reception hole along towing pad from receiving the hole, finish and lay the sleeve pipe operation by the haulage cable drag spring thimble; At drag spring thimble simultaneously, in order to reduce friction, the Lubricants of can on bushing outer surface, annotating.
Use method of construction of the present invention, can reduce workload to a great extent and only use smaller power and than the machinery of light weight.For example, if use traditional hand digging push pipe construction method for crossing, must carried out hand digging by the sleeve pipe front end of pushing tow, need to use diameter greater than 1 meter sleeve pipe, corresponding therewith, should use thrust to cheat, thereby increase work difficulty greater than 150 tons pushing tow machinery and the huge operation of excavation, and when passing through, can make the sleeve pipe sedimentation, depart from predetermined route, thereby influence construction quality owing to running into complex geological conditions.If use method of construction of the present invention, owing to need not to carry out hand digging at the sleeve pipe front end, used casing diameter is much smaller, can adopt sleeve pipe less than φ 425, therefore construction plant weight and peace machine engineering work load are all little a lot, and construction access road carries out along the less pilot hole of diameter, and the precision and the quality of construction also are improved, and sleeve pipe can reach below 5/1000ths in the side-play amount on the vertical and horizontal.
Advantage of the present invention is, do not need large-scale construction equipment, and the plant capacity of use is little, in light weight, volume is little, the construction work amount is little, and changing heavy manual operation is mechanized construction, and construction cost is low, can reduce expenses more than 20% the construction quality height.Be applicable to that oil pipe, natural gas line and other pipelines pass through the construction that the pipeline of road, urban sector, massif and complex geological condition passes through.
Fig. 1 is for the dredge operation hole and receive the hole schematic representation.Fig. 2 is for getting out the pilot hole schematic representation.Fig. 3 expands pilot hole to be the towing pad schematic representation.Fig. 4 passes through schematic representation for drag spring thimble.Fig. 1, Fig. 2, Fig. 3 and Fig. 4 are described as follows: wherein, 1 is the operation hole, and 2 for receiving the hole, and 3 is driling machine, and 4 is pilot hole, and 5 is reamer, and 6 is haulage cable, and 7 is towing pad, and 8 is sleeve pipe, and 9 is tractor.
One embodiment of the present of invention, in conjunction with the accompanying drawings 1, that accompanying drawing 2, accompanying drawing 3 and accompanying drawing 4 are described its construction sequence is as follows: excavate operation hole 1, top and terminal at the construction site two ends and receive hole 2.In 1 bottom, operation hole driling machine 3 is installed, is started driling machine 3 gets out minor diameter on respective depth and direction pilot hole 4, receive hole 2 until reaching.In receiving hole 2, the reamer 5 that haulage cable 6 tops are housed is contained on the drilling tool, start drilling tool, reamer 5 is returned to rotation reaming limit, direction limit, operation hole from receiving the hole along pilot hole 4, pilot hole 4 is expanded as towing pad 7, up to operation hole 1, and move haulage cable 6 to operation and cheat in 1.Remove driling machine 3 in operation hole 1, place sleeve pipe 8, tractor 9 is installed in receiving hole 2, haulage cable 6 tops are contained in sleeve pipe 8 front ends, haulage cable 6 terminals are contained on the tractor 9.Start tractor 9, haulage cable 6 is received in the hole 2 until reaching along towing pad 7 drag spring thimbles 8.
