Embodiment Construction

[0062] A construction method of a composite pile, comprising the following steps:

[0063] A kind of construction method of composite pile is characterized in that: comprises the following steps:

[0064] (1) Construction of the first pile: including one of the following methods:

[0065] Method A:

[0066] (1) Move the machine into place: move the equipment, and place the outer tube on the set pile position;

[0067] (2) Immersed tube: sink the outer tube to the set depth;

[0068] (3) Pouring forming: lift up the internal ramming system, and pour the pile body;

[0069] (4) Tube forming: pull out the outer tube to form the pile; according to the design requirements, the internal ramming system can press the concrete surface and then pull out the outer tube to form the pile.

[0070] Method B:

[0071] (1) Move the machine into place: move the equipment and place the drill pipe on the set pile position;

[0072] (2) Spinning sinking: Spinning and sinking the drill pipe ...

Abstract

The invention discloses a composite pile and a construction method thereof. The composite pile comprises a first pile as a peripheral pile, and a second pile as a core pile, wherein the first pile is a cast-in-situ pile; a second pile is a cast-in-situ pile or a precast pile; a centre distance d between the first pile and the second pile is equal to 0; area ratio S of the second pile to the first pile is S2/S1; length ratio L of the second pile to the first pile is L2/L1, wherein S belongs to (0, 1), and L is more than 0.5. According to the invention, construction is convenient and reasonable; proper construction devices and construction processes are selected according to stratum conditions, site conditions, ambient environment and work amount; tube sinking and tube drawing systems can be a set of device, and also can be different independent devices; a pile is constructed integrally by a device, and also is constructed by a plurality of devices; and a plurality of devices operate in a flow line.

Description

technical field [0001] The invention relates to a composite pile and a construction method thereof. Background technique [0002] The existing construction techniques of immersed tube grouting piles, rammed piles, and prefabricated piles are generally difficult to construct and cross when encountering hard soil areas. Generally, soil borrowing holes are used, which lose part of the bearing capacity, and are often thankless; generally encounter soft soil areas. Land areas try their best to increase the lengthening piles to obtain bearing capacity, which is often costly and not thankful. Contents of the invention [0003] The object of the present invention is to provide a composite pile with good construction environmental protection, good cost performance and reliable quality and its construction method. [0004] Technical solution of the present invention is: [0005] A composite pile, characterized in that it includes a first pile as a peripheral pile and a second pile...
