[0031] Embodiment 1
[0032] A roadbed engineering in Shenzhen uses flowable backfill for backfilling. According to a design requirement, a backfilled roadbed needs to be in line with requirements on strength and permeability, so as to guarantee a bearing capacity and a permeation power of the roadbed. In view of economy of the engineering and convenience in construction, a flowable backfill sliding formwork perforating apparatus and a construction method thereof are used for construction. A road surface is designed to be 8 m wide, a single flowable backfill section is 8 m long and a backfilled height is 0.3 m. Specifically, the method includes the following steps:
[0033] (1) Localization: a tendency of a road in need of being filled with soil is determined according to a designed road surface drawing; and then, a movement path of a sliding formwork is determined and labeled.
[0034] (2) Pavement of guide track: a sliding guide track is paved, where a plurality of sliding guide tracks may be paved side by side according to a construction requirement; and a bolt on a side, back on to the sliding formwork, of a sliding apparatus is struck into the underground in a hammering manner, thus fixing a position of the sliding apparatus.
[0035] (3) Setting of pouring height: a concrete block having a height of 0.3 m and matched with a sliding groove of the sliding apparatus in width is pre-poured, and the concrete block having a formed strength is stuffed into the sliding groove.
[0036] (4) Pouring of flowable roadbed soil: a clapboard is placed first in a transverse direction of the sliding apparatus to serve as a frame-shaped formwork for the flowable soil; roadbed fill having a flowability is poured, with that the flowable soil is overflowed from a surface of the concrete stuffed into the sliding groove as a pouring control standard; and upon the completion of the pouring, a layer of plastic film is paved on a surface of the slowable soil, so that the road surface of the slowable soil is separated from the sliding formwork to be placed thereon.
[0037] (5) Placement of sliding formwork: the clapboard on one side is detached; the sliding formwork slides to the surface of the flowable soil under the joint action of a jack and a horizontal counter-force frame on an upper surface of the sliding apparatus; and when sliding to the sliding groove, the sliding formwork falls into the sliding groove under the action of a self weight to be fixed.
[0038] (6) Perforating preparation: a lubricating material is coated on an outer wall of a perforating cone of a perforating apparatus, so as not to affect a shape of a hole after the perforating cone is pulled out together with the perforating apparatus; and according to a designed perforating depth, an L-shaped depth limiting pin (which has a certain magnetism, and can be absorbed to the hole to some extent when inserted into the hole, so as not to become loose in response to the striking of a rubber hammer) is inserted into the hole of the perforating apparatus; the perforating cone is placed onto the hole of the sliding formwork; and the perforating apparatus is pressed into the flowable soil first in an artificial pressing manner, then struck to a predetermined depth by the use of the rubber hammer, and pulled out after the flowable roadbed soil reaches to a strength of 30 kPa.
[0039] (7) Jacking of sliding formwork: the concrete block that is pre-poured and matched with the sliding groove in width is taken out; and then, a vertical jack is placed into the sliding groove and a jacking force is applied, so that the sliding formwork moves upward to a horizontal plane of the sliding apparatus.
[0040] (8) Movement of sliding formwork: the sliding formwork having the hole slides forward to a next to-be-poured area by means of a joint action of a horizontal jack and the horizontal counter-force frame, and the above operation is repeated till the completion of all perforating work.
