Embodiment Construction

[0016] Such as figure 1 As shown, a construction method for enhancing earthwork compaction by lime-sand piles in a small-span well-shaped beam includes the following steps.

[0017] S100~The site is leveled and compacted; the atrium backfill soil between the ground beam and the ground beam of the independent foundation atrium backfill soil is reinforced with a spiral mechanical hole-forming lime-sand pile, and the surface of the atrium soil of the independent foundation is 300mm thick The surface layer soil shall be rammed artificially with a tamping machine, and the lack of soil shall be filled with silty sand to the design fill level after tamping.

[0018] S200~Measuring and setting out positioning piles; according to the layout plan of the lime-sand piles, after the site is leveled, use the total station and meter ruler to release the construction pile positions of each pile, insert bamboo sticks and sprinkle white ash marks. The layout of the gray-sand piles is as follows...

Abstract

The invention belongs to the technical field of building construction, and particularly relates to a construction method for enhancing earthwork compactness of a small-span #-shaped beam inner lime sand pile. The construction method comprises the following steps that S100, site leveling and tamping are conducted; S200, surveying, setting out and positioning of the pile are conducted; S300, a hole forming drilling machine is in place, and hole forming work is conducted; S400, the hole depth and the hole diameter are checked after emptying is conducted; S500, evenly-mixed lime sand is poured into a hole in two times, and layered tamping is conducted; S600, clay sealing and tamping are conducted; and S700, pile forming acceptance is conducted, and construction of the next pile is conducted. According to the construction method, the manufacturing cost is low, the construction period is short, construction is convenient, and the effect is remarkable.

Description

technical field [0001] The invention belongs to the technical field of building construction, in particular to a construction method for enhancing earthwork compaction with lime-sand piles in small-span well-shaped beams. Background technique [0002] In construction projects without a basement, pile foundations and independent foundations are generally used. The normal construction process of the independent foundation house core should be to backfill the earth in layers to the ground beams in time after the construction of the independent foundation caps and frame columns is completed and before the construction of the ground beams. However, when a building with a basement is connected to an independent foundation without a basement, the earthwork can only be filled as a whole after the waterproofing and waterproofing of the outer wall of the basement and the waterproof protective layer are completed. After the main structure, the independent foundation room core soil is f...
