Construction method for forming pile wall type retaining wall

Abstract

The invention discloses a construction method for forming a pile wall type retaining wall, which comprises the following steps: (a) constructing a plurality of drilling or punching retaining piles arranged in rows along a direction of an enclosure structure; (b) paring off soil mass among pile holes with a plane set-hammer to form a section of continuous slotted holes; (c) lowering steel reinforcement cages of the bored retaining piles orderly; (d) lowering a conduit, casting underwater concrete for the bored piles and the conduit together, and forming a section of continuous wall body; and (e) constructing a waterproof jet grouting pile or a deep-cement-mixed pile at each joint of the continuous wall bodies. Because a construction method for comprehensively arranging piles and casting a plurality of piles continuously is adopted, the leakage opportunities between piles are reduced greatly, the integrity of the enclosure structure is improved correspondingly, and the safety of a foundation pit is improved.

Description

technical field [0001] The invention relates to a building construction method, in particular to a construction method for retaining wall enclosure structures. Background technique [0002] The cost of the traditional pile-row enclosure structure is relatively lower than that of the underground diaphragm wall, but the water-stop effect between the piles is difficult to guarantee, and water leakage and quicksand are prone to occur, causing foundation pit collapse accidents. Although the water-stopping effect of the underground diaphragm wall is good, the construction requires grab buckets and large-scale lifting equipment, which makes the construction difficult and the cost is too high. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems, and provide a continuous pouring method using comprehensive pile arrangement and multiple piles, which greatly reduces the chance of leakage between piles, improves the integrity...
