Problems solved by technology

[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 lifting equipment, which makes the construction difficult and the cost is too high

Embodiment Construction

[0020] Such as figure 2 image 3 Shown, the forming construction method of a kind of pile wall type retaining wall of the present invention comprises the following steps:

[0021] (a) Construct multiple rows of bored or punched support piles along the direction of the enclosure structure;

[0022] (b) Use a square hammer to repair the soil between the pile holes to form a continuous slot;

[0023] (c) lowering the above-mentioned hole-forming support pile reinforcement cage in turn;

[0024] (d) down the conduit, and pour the underwater concrete of the above-mentioned hole-forming piles together to form a section of continuous wall;

[0025] (e) Construction of water-stop rotary grouting piles or deep cement mixing piles at the joints of the continuous walls of each section.

[0026] Among them, the number of drilled (punched) hole piles contained in each section of the above groove is determined according to geological conditions, construction capacity, mud pool capacity...

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...
