Description
Technical field
The present invention relates to a kind of combined type ecological revetment construction method, particularly relate to assembling anchor pole arched framework combined type ecological revetment construction method.
Technical background
Under the fast development of China's communication, high-fill roadbed Quantity constantly increases.Due to the particularity of high-fill roadbed self, roadbed is easy to the situation occurring landslide, causes great impact to the safety traffic of vehicle.Therefore, high earth roadbed side slope protection is had higher requirement.
Traditional bank protecting method is generally main building materials with hard materials such as cement, building stones, concrete, goes to think deeply stability of slope in design with the angle of mechanics.Traditional bank protection is broadly divided into shallow-layer protection class bank protection, stone-laying class bank protection, sash bank protection, facing wall bank protection and the mixed class bank protection of spray.There is a lot of shortcoming in traditional bank protecting method; as: high-fill roadbed difficulty of construction is large; engineering time is long; safety and stability is difficult to ensure; high slope prop up gear protection and drainage unsound, easily there are the quality problems such as distortion, depression in tall earth fill bank protection, and one-time investment is large; be difficult to recover natural vegetation, be unfavorable for protection and the water and soil conservation of ecological environment.Comparatively dull in appearance stiff, in most cases inharmonious with the view of periphery, disagree with the development trend focusing on preserving the ecological environment at present.Although traditional anchor pole arched framework bank protection is conducive to improving the safety factor of soil layer and strengthening the stability of rock slope, this technology greatly alleviate works deadweight, save engineering material and guarantee the safety of engineering and stable, absorb again simultaneously mortar flag stone (concrete block) skeleton plant grass and protect handsome in appearance, be convenient to the advantage of afforesting, but traditional arched framework bank protection is all cast-in-place, drainage system is also unsound, for high-fill roadbed difficulty of construction, the easy impeded drainage of bank protection and cause bank protection unstability.
Given this, need a kind of easy construction of invention at present badly, stability is strong, shortens the engineering time, can realize the assembling anchor pole arched framework combined type ecological revetment construction method of anchor pole and arched framework site assembly and built-in three-dimensional drainage system.
Summary of the invention
The object of the present invention is to provide a kind of easy construction, stability is strong, shortens the engineering time, can realize anchor pole and arched framework site assembly, and arched framework inside arranges the assembling anchor pole arched framework combined type ecological revetment construction method of the features such as drainage system.
For achieving the above object, present invention employs following technical scheme:
This assembling anchor pole arched framework combined type ecological revetment construction method, mainly comprises the following steps:
1) anchor bolt construction: adopt anhydrous dry drill method to be drilled with bolthole at side slope of embankment assigned address, after scaffold building is good, machinery according to the position, hole of reserving in advance, holed by bottom carrying out by rows, play what a boring, before laying anchor pole, with material, aperture must be blocked.When rig is holed, drilling rod perpendicular to side slope face, must be squeezed in embankment by drilling direction uniform speed slow.After bolthole is drilled to type, carry out hole clearly.Arrange anchor pole positioning bar at the assigned address of anchor pole, to ensure that anchor pole is fixed on position, hole central authorities, anchor pole inserts in bolthole with artificial after making by anchor pole, then carries out bolthole slip casting.
2) foundation trench excavation: arch form skeleton foundation trench adopts the method for hand excavation, should note the accurate of physical dimension position during foundation trench excavation, every 2 ~ 3m excavation together anti-skidding step in vertical skeleton foundation trench.For the excavation of arch ring circular arc portion foundation trench, the instrument of selection of small is answered to carry out excavating to ensure that arch section is natural, level and smooth.
3) arched framework is installed: arrange pin wall after sough excavates, then prefabricated counterfort and the installation of prefabricated arch ring is carried out, prefabricated counterfort A and prefabricated arch ring A is temporarily fixed in the arched framework foundation trench dug in advance, then prefabricated counterfort A is welded with the main muscle of reserved arched framework of prefabricated arch ring A, utilize branch sleeve built-in PVC drain pipe to be linked together, anchor pole is linked together by anchor pole positioning bar and the main muscle of arched framework; L-type pvc pipe exposed parts arranges anti-blocking filter screen; The reserved thin PVC drain pipe outer wall of bank protection top prefabricated counterfort B is coated with one deck marine glue, and be then inserted in the inner PVC drain pipe of prefabricated arch ring B, top prefabricated counterfort B and prefabricated arch ring A is connected and fixed by screw rod faulting of slab ends.
4) connecting band construction: the anchor pole positioning bar of anchor pole welds then to concreting in the reserved bolthole of prefabricated arched framework by the part for reserved bolthole with the main muscle of arched framework, template is installed, then concreting for prefabricated counterfort A and prefabricated arch ring A junction.
5) anchor pole stretch-draw: after anchor pole stretch-draw, with ground tackle, anchor pole is fixed.
6) careless blanket is transplanted: utilize arched framework by embedding for careless blanket pressure and coordinate wooden peg by firm for careless blanket.
The present invention has following feature and beneficial effect:
(1) arch ring of arched framework and counterfort are prefabricated in advance, prefabricated counterfort and arch ring reserve bolthole and reserved dowel, the reserved dowel of prefabricated counterfort and prefabricated arch ring welds together and arranges anchor pole, connecting band concreting both ensure that globality and the stability of arched framework, realize again the site assembly of arched framework and anchor pole, stability is strong, and efficiency of construction is high.
(2) the inner pre-buried gutter of arched framework, gutter is connected and fixed by locating steel ring and positioning bar and the main muscle of arched framework, the reserved drainpipe of prefabricated counterfort and arch ring is linked together by branch sleeve, and form built-in three-dimensional subgrade drainage system, drainage effect is good.
(3) in arch ring, soil body exposed part arranges ecological grass mat, and ecological grass mat is pressed solidly by the outer male structure of arched framework, is conducive to protection and the water and soil conservation of ecological environment.
