Description

Assembled anchor pole arched framework combined type ecological revetment construction method
Technical field
The present invention relates to a kind of combined type ecological revetment construction method, more particularly to assembled anchor pole arched framework combined type Ecological revetment construction method.
Technical background
Under the fast development of China's communication, high-fill roadbed Quantity is continuously increased.Due to high-fill roadbed The particularity of itself, roadbed is easy to the situation for occurring coming down, and the safety traffic to vehicle causes strong influence.Therefore, Higher requirement is proposed to high earth roadbed side slope protection.
Traditional bank protecting method is general using hard materials such as cement, building stones, concrete as main building materials, in design with power Angle goes to think deeply stability of slope.Traditional bank protection is broadly divided into shallow-layer protection class bank protection, stone-laying class bank protection, sash shield Slope, facing wall bank protection and the mixed class bank protection of spray.There are many shortcomings in traditional bank protecting method, such as:High-fill roadbed difficulty of construction is big, Engineering time is long, and safety and stability is difficult to ensure that, the protection of high slope supporting and retaining system and pumping equipment are unsound, and tall earth fill bank protection is easy There are the quality problems such as deformation, depression, and one-time investment is big, it is difficult to recover natural vegetation, be unfavorable for the guarantor of ecological environment Shield and water and soil conservation.More dull stiff in appearance, the landscape in most cases with periphery is uncoordinated, with focusing on protecting at present The development trend of ecological environment is disagreed.Although traditional anchor pole arched framework bank protection be conducive to improve soil layer safety coefficient and Strengthen the stability of rock slope, this technology mitigates the deadweight of works, saves engineering material and ensures the peace of engineering significantly Entirely and stably, while absorbing the advantage that is handsome in appearance, being easy to greening of mortar flag stone (concrete block) skeleton grass planting protection again, But traditional arched framework bank protection is all cast-in-place, drainage system is also unsound, for high-fill roadbed difficulty of construction, bank protection Easy impeded drainage and cause bank protection unstability.
In consideration of it, needing a kind of easy construction of invention badly at present, stability is strong, shortens the engineering time, and anchor pole and arch can be achieved The assembled anchor pole arched framework combined type ecological revetment construction method of shape skeleton assembled in situ and built-in three-dimensional drainage system.
The content of the invention
It is an object of the invention to provide a kind of easy construction, stability is strong, shortens the engineering time, and anchor pole and arch can be achieved The assembled anchor pole arched framework combined type ecology shield for the features such as drainage system is set inside shape skeleton assembled in situ, arched framework Slope construction method.
To achieve the above object, present invention employs following technical scheme:
This assembled anchor pole arched framework combined type ecological revetment construction method, is mainly included the following steps that:
1) anchor bolt construction:Bolthole is drilled with using anhydrous dry drill method in side slope of embankment specified location, scaffold building it is good with Afterwards, machinery according to the hole position set in advance, by bottom, progress by rows drills, and plays what a drilling, is laying anchor pole Before, aperture must be blocked with material.When rig is drilled, drilling direction must be perpendicular to side slope face, uniform speed slow Drilling rod is squeezed into embankment.Bolthole is drilled to after type, carries out borehole cleaning.Anchor pole positioning bar is set in the specified location of anchor pole, to protect Card anchor pole is fixed on hole position center, and anchor pole manually inserts anchor pole in bolthole after making, and then carries out bolthole note Slurry.
2) foundation trench is excavated:The method that arch form skeleton foundation trench uses hand excavation, foundation trench should be noted that physical dimension position when excavating That puts is accurate, and anti-skidding step together is excavated every 2~3m in vertical skeleton foundation trench.For opening for arch ring circular arc portion foundation trench Dig, answer the instrument of selection of small to be excavated to ensure that arch section is natural, smooth.
3) arched framework is installed:Sough sets pin wall after excavating, and then carries out prefabricated counterfort and prefabricated arch ring Install, prefabricated counterfort A and prefabricated arch ring A are temporarily fixed in the arched framework foundation trench dug in advance, then to prefabricated counterfort A Welded, built-in PVC drain pipe linked together with prefabricated arch ring A reserved arched framework cage bar using branch sleeve, Anchor pole is linked together by anchor pole positioning bar with arched framework cage bar;L-type pvc pipe exposed parts set anti-blocking filter screen;Bank protection The prefabricated counterfort B in top reserved thin PVC drain pipe outer wall applies one layer of marine glue, is then inserted into PVC drainings inside prefabricated arch ring B In pipe, the prefabricated counterfort B in top and prefabricated arch ring A is connected and fixed by screw rod faulting of slab ends.
4) belt construction is connected:The anchor pole positioning bar of anchor pole and arched framework cage bar are welded for the part for reserving bolthole Then the casting concrete into the reserved bolthole of prefabricated arched framework, is installed for prefabricated counterfort A with prefabricated arch ring A junctions Template, then casting concrete.
5) anchor pole tensioning:After anchor pole tensioning, anchor pole is fixed with anchorage.
6) careless blanket transplanting:Careless blanket is snapped using arched framework and coordinates wooden peg to consolidate careless blanket.
The characteristics of present invention has following and beneficial effect:
(1) arch ring of arched framework is prefabricated in advance with counterfort, and prefabricated counterfort is reserved bolthole and reserved and is connected with arch ring Muscle, the reserved dowel of prefabricated counterfort and prefabricated arch ring welds together and sets anchor pole, and connect band casting concrete both ensured The globality and stability of arched framework, realizes the assembled in situ of arched framework and anchor pole again, and stability is strong, efficiency of construction It is high.
(2) pre-buried drainpipe inside arched framework, drainpipe is connected by positioning steel ring and positioning bar with arched framework cage bar Fixation is connect, the reserved drainpipe of prefabricated counterfort and arch ring is linked together by branch sleeve, form built-in three-dimensional roadbed row Water system, drainage effect is good.
(3) soil body exposed part sets ecological grass mat in arch ring, and ecological grass mat presses solid by the outer male structure of arched framework, Be conducive to the protection and water and soil conservation of ecological environment.
