Abstract
The invention discloses a hydraulic drill follow-up pipe-shed construction method. Two guide tracks are laid on a work site, which is perpendicular to an axis of a tunnel, on a construction tunnel face, and are used for realizing traveling of a drilling machine platform and positioning of a pipe-shed, during construction, packed hole drilling of a slurry protecting wall is formed by a hydraulic drill from a tunnel access opening at the outer edge of a frame via the drilling machine platform according to certain distances, drilling and follow-up pipe construction are carried out simultaneously, finally, advanced pre-supporting is formed, the purposes of increasing rigidity and bearing ability of a stratum and unevenly and normally distributing uniformly distributed load are achieved, surface subsidence in a follow-up frame digging process is reduced, and safety of civilization sites is ensured. In the method, the quantity of construction operators and the quantity of equipment are reduced, effects are improved, a pipe-shed circulating period is shortened, a construction schedule is ensured, and engineering manufacturing cost is reduced. The method is a brand-new pipe-shed construction method for an extremely shallow-buried and large-section tunnel, not only is convenient in construction when used for soil layers and loose, soft and unstable strata, but also is more favorable for controlling surface subsidence, and is safe and controllable.
Description
Technical field
The present invention relates to a kind of water drilling follow-up pipe shed construction method, this construction method is specially adapted to down to wear an ultra shallow and buries soil property and the unstable geology of loose weak and protect exceptional structure to construct.
Background technology
Some speedway can wear down the area of burying national historical relic, as elm god speedway can wear Ruins of Great Wall of the Qin Dynasty down, for protecting national historical relic, open cut can not pass through with cutting form, tunnel excavation method must be adopted to pass through.
Carry out follow-up pipe roof construction when protecting national historical relic, home and abroad there is no the construction technology in similar tunnel at present, can not for the construction method used for reference.
Summary of the invention
The technical problem to be solved in the present invention is: for above-mentioned situation, provides a kind of easy construction in soil layer and the unstable geology of loose weak, is beneficial to control surface settlement, is beneficial to the water drilling follow-up pipe shed construction method protecting national historical relic.
The object of the invention is realized by following technical proposals:
A kind of water drilling follow-up pipe shed construction method, at construction face place, two guide rails are laid perpendicular on the work-yard of tunnel axis, for drilling machine platform walking and pipe canopy location, in construction, pass through drilling machine platform, water drilling is adopted to form mud off packed hole drilling from tunnel's entrance and exit at a certain distance in framework outer, creep into while follow pipe construction, finally form leading pre-supporting, reach the rigidity and supporting capacity that improve stratum, the uneven normal distribution object of evenly distributed load, reduce surface settlement in follow-up framework digging process, guarantee cultural sight safety.
As preferably, the method comprises the steps: further
1) locate
1.1 preparations of construction: face build, personnel, facility, test and surveying work in place, reach requirements for starting construction;
1.2 smooth locations: mainly refer to smooth drilling machine construction place, for lower step operation provides work-yard;
1.3 lay track: at construction face place, lay two guide rails perpendicular on the work-yard of tunnel axis, for the walking of rig pylon, create conditions to later stage pipe canopy rig location, walking and construction;
