Description

Technical Field

[0001] The invention relates to the technical field of pile foundation construction, and in particular to a full-interlocking pile and a construction method. Background Art

[0002] The interlocking pile is a kind of enclosure structure with good water-stopping and supporting functions. It has the advantages of flexible layout, small hole depth limit, high construction efficiency, small impact on the surrounding environment and low construction cost. It is widely used in foundation engineering of bridges, building construction and underground structures. There are three main types of interlocking piles: plain-plain interlocking, meat-vegetarian interlocking and meat-meat interlocking. Compared with the former two, meat-meat interlocking piles have better water-stopping and supporting capabilities, and are more suitable for the design and construction of foundation pits with poor geological conditions, deep foundation pits and greater horizontal forces. However, the complex construction process, high construction cost and difficulty in precision control of meat-meat interlocking piles restrict the wide application of meat-meat interlocking piles in the industry.

[0003] The general construction method of meat-vegetable interlocking piles is: after the guide wall construction is completed, construct the A (vegetable) piles first, and then construct the B (vegetable) piles. The construction of the B piles is completed after the initial setting of the A pile concrete and before the final setting. When constructing the B piles, the concrete of the intersecting parts of the adjacent A piles needs to be cut off to achieve interlocking.

[0004] The invention with Chinese patent publication number CN111519611A discloses a method for constructing interlocking piles that can laterally connect steel cages. Connectors that are vertically plugged into adjacent steel cages are arranged in two A-type pile holes to enhance the lateral stability between adjacent concrete piles.

[0005] The invention patent with Chinese patent publication number CN103266600 discloses an interlocking pile of a full-reinforced pile and a construction method thereof. A full-revolving drilling rig is used to drill holes, a square steel cage is added to the plain pile, and PVC pipes are fixed on both sides of the square steel cage. During the construction of the circular reinforced concrete, a part of the PVC pipe is cut off to connect the circular steel cage concrete pile and the square steel cage concrete pile together, thereby improving the support capacity of the entire interlocking pile.

[0006] The above invention technology realizes the construction of full-interlocking piles by setting connecting parts or square steel cages between two circular steel cage pile bodies and then casting the pile body.
