Problems solved by technology

At present, the methods used include geosynthetics adding hoops on the top of the pile, tubular grid reinforcement, etc., but the materials themselves of these methods will be deformed under tension, and a certain lateral displacement will occur in the hooped section of the pile; There is a method of wrapping the top of the hooped pile body with prestressed reinforced concrete, but this method is costly in materials and labor

Embodiment Construction

[0016] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] A method for preventing bulk material piles from being bulged and damaged in a composite foundation, comprising the following steps: setting a circle of first foundation walls 2 outside the pile body 1 of the pile body 1 adjacent to the first foundation wall outside the pile body 1 2 are connected with a second foundation wall 3, such as figure 1 and figure 2 shown.

[0018] The first foundation wall 2 and the second foundation wall 3 are from the top of the pile body 1 to a depth of 2D away from the top of the pile body 1 , where D is the diameter of the pile body 1 .

[0019] The thickness of the first foundation wall 2 and the second foundation wall 3 is 120-370mm.

[0020] Both the first foundation wall 2 and the second foundation wall 3 are made of common solid bricks.

[0021] Such as image 3 As shown, if the piles are arranged in square or rectan...

Abstract

The invention discloses a method for preventing a bulk solid material pile from damaging due to expanding in a composite foundation. The upper portions outside pile bodies of the bulk solid material pile are provided with a circle of first foundation walls, a second foundation wall is connected between first foundation walls outside the adjacent pile bodies, the first foundation walls and the second foundation walls are arranged at the part from the tops of the pile bodies to the position 2D away from the top portions of the pile bodies, and D is the diameter of the pile body. Mutual restraining of the adjacent pile bodies is fully utilized, and the method is economical and practical.

Description

technical field [0001] The invention belongs to the technical field of bulk material piles in composite foundations, and in particular relates to a method for preventing swelling and damage of piles made of bulk materials in composite foundations. Background technique [0002] Bulk material piles (gravel piles, sand piles, gravel piles, etc.). Taking gravel piles as an example, it is a good method to reinforce and treat loose and soft soil foundations. The composite foundation formed by the gravel pile method can improve the bearing capacity of the foundation and reduce settlement. The gravel pile body has good water permeability, which is conducive to the dissipation of excess static pore water pressure, and has good economic and social benefits. Most of the failure forms of bulk material piles represented by gravel piles are bulging damage at the upper part (according to the experimental results, the place where bulging damage is most likely to occur is 2 / 3D from the top ...
