Embodiment Construction

[0045] Attached to the following Figure 1-3 This application will be described in further detail.

[0046] The embodiment of the present application discloses a rigid composite pile. refer to figure 1 , the stiffness composite pile includes four composite piles 1 inserted in the in-situ soil layer 7, the lower surface of the in-situ soil layer 7 is a bearing layer 8, and the bottom end of the composite pile 1 is inserted into the in-situ soil layer 7, each The bottom ends of the root composite piles 1 are all abutted on the upper surface of the bearing layer 8 , so that the bearing layer 8 can achieve stable support for the pile body.

[0047] continue to refer to figure 1, each composite pile 1 includes a concrete pile 11 and a PHC pipe pile 12 fixed in the concrete pile 11 , and the top of the PHC pipe pile 12 is located above the top of the concrete pile 11 . Each composite pile 1 is provided with a positioning column 2 for fixing the composite pile 1, a bracket 3 for ...

Abstract

The invention relates to a construction method of a stiff composite pile. The method comprises the following steps that firstly, stirring and curing are carried out a curing material and in-situ soil on the upper surface of an in-situ soil layer in situ to form a curing layer; secondly, four composite piles are driven into the in-situ soil layer in sequence, and the four composite piles are distributed in a quadrangle shape; thirdly, a positioning column used for positioning the composite pile is installed on each composite pile, and the positioning columns are fixed to a fixing layer; fourthly, the four positioning columns are connected together through a support; fifthly, each composite pile is provided with a clamping mechanism used for clamping the corresponding positioning column; and sixthly, the composite piles and the positioning columns are fixed together through the clamping mechanisms. The installation stability of the stiff composite pile is improved through the method.

Description

technical field [0001] The present application relates to a foundation treatment method, in particular to a construction method for forming a rigid composite pile. Background technique [0002] Stiff composite pile refers to the application of PHC pipe piles in the center of the already cast concrete piles to form stiff core cement-soil composite piles. Cement mixing piles with a diameter of 600-1000mm are often used in soft soil foundations. When the cement is not hardened, the core piles with a diameter of 220-270mm are used to form plain concrete and cement-soil composite piles. Insert steel bars and steel pipes to form reinforced concrete cores, and insert pipe piles or square piles into them to form high bearing capacity composite piles. [0003] In soft soil foundations, the commonly used reinforcement method for stiff composite piles is the composite foundation method. The composite foundation method is to drive the composite piles into the in-situ soil layer to tig...
