Embodiment

[0019] The above solution will be further described below in conjunction with specific embodiments. It should be understood that these examples are used to illustrate the present invention and not to limit the scope of the present invention. The implementation conditions used in the examples can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not indicated are usually the conditions in routine experiments.

[0020] A treatment method for pipe pile defects, pipe pile 1 has relatively serious defects below 2m from the pile top,

[0021] Step 1, excavate the soil in the pipe pile 1 to a certain depth below the defect position 2;

[0022] Step 2: Reinforcing the pipe pile 1 with reinforced concrete core filling, the depth of the core filling is about 2m down from the defect position 2;

[0023] Step 3, the outer circle of the pipe pile 1 is supported by the casing 3, and the soil between the periphery of the ...

Abstract

The invention discloses a tubular pile defect processing method. A tubular pile has a serious defect at the places below the place 2m below the top of the pile. The method is characterized in that: step 1, drawing out soil in the tubular pile to certain depth below the defect; step 2, filling reinforced concrete in the tubular pile to reinforce the pile, wherein the filling depth is about 2m below the defect; step 3, timbering the tubular pile through a pile casing which surrounds the tubular pile and digging out soil between the circumference of the tubular pile and the pile casing at a depth of about 2m below the defect; and step 4, pouring reinforced concrete into the area between the circumference of the tubular pile and the pile casing to a depth equal to the digging depth in step 3. The method disclosed by the invention is simple in process and low in cost and is easy to construct.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a processing method for pipe pile defects. Background technique [0002] Defects such as broken piles caused by pipe piles during construction and due to excavation and other reasons, especially in soft soil areas, are more common. The foundation piles identified as Type III and Type IV piles by the inspection unit usually need to analyze the cause of the defects, and propose appropriate reinforcement plans. At present, the existing conventional treatment methods include: filling core reinforcement method, pile filling method, etc. The core-filled reinforcement method cannot guarantee the bearing capacity after treatment for pipe piles with serious defects; while the pile-filled method has a greater impact on the construction period and cost due to the difficulty of construction. Therefore, there is no treatment method with relatively simple process and low cost f...
