Stiff composite pile construction process

[0030] Example 1:

[0031] S1: Construction of carrier piles

[0032] a. Carrier pile uses φ500mm cement soil mixing pile, all cartridges follow into the impact molding hole, the hole in the hole, the cement dial in the air diamond region is 9%, the effective pile length area cement is 17%;

[0033] b. The carrier construction is completed, and the pile driver is in place.

[0034] S2: Carrier pile driver

[0035] S3: Defining prefabricated piles, use static or hammering to send pile to design elevation

[0036] a. Prefabricated piles adopt a prestressed concrete pipe pile, an effective pile length of 42m, and the prefabricated pile body is taken within 6 hours after the carrier construction is completed;

[0037] b. After the mixing pile driver is applied, the static press is positioned, the positioning pile center error is controlled within 10mm, and the static press should be aligned with the center point of the pile position, and start the platform of the platform. Cylinder, corr

[0046] S1: Construction of carrier piles

[0047] a. Carrier pile uses φ700mm cement soil mixing pile, all cartridge follow-up impact molding, hole in the hole, the cement mixture in the air diamond region is 10%, the effective pile length area cement is 19%;

[0048] b. The carrier construction is completed, and the pile driver is in place.

[0050] S3: Defining prefabricated piles, use static or hammering to send pile to design elevation

[0051] a. Prefabricated piles adopt a prestressed concrete pipe pile, an effective pile length of 42m, and the prefabricated pile body is taken within 6 hours after the carrier construction is completed;

[0052] b. After the mixing pile driver is applied, the static press is positioned, the positioning pile center error is controlled within 10mm, and the static press should be aligned with the center point of the pile position, and start the platform of the platform. Cylinder, corrected pile m

[0060] Example 3:

[0061] S1: Construction of carrier piles

[0062] a. Carrier pile uses φ900mm cement soil mixing pile, full cartridge follow into the impact molding hole, perforation of fine stone concrete, hole in the air diamond region is 9-11%, effective pile length area cement incoming amount is twenty one%;

[0063] b. The carrier construction is completed, and the pile driver is in place.
