Problems solved by technology

However, the pile body of this type of pile is made of cast-in-place concrete. In silty soil or soil layer with high water content or saturated soil, it is easy to have shrinkage and broken piles at the junction of the pile body and the pile end. problem, seriously affecting the bearing capacity of the pile, resulting in excessive settlement of the pile

Embodiment Construction

[0036] figure 1 It is the process diagram of the prefabrication method of the concrete pile of the present invention, as figure 1 As shown in middle a, the casing 1 is sunk vertically into the hole by power in the foundation until the predetermined depth; then, as figure 1 Shown in middle b, the sizing mold 2 that will assemble is sunk in the casing 1; Then, as figure 1 As shown in middle c, a reinforcement cage 3 is inserted into the inner cavity of the shaping mold 2, and then concrete 4 is poured into the inner cavity of the shaping mold 2, and a vibrator 5 is inserted into the inner cavity of the shaping mold 2 to vibrate the concrete dense; then, if figure 1 Shown in d, until the inner cavity of the shaping mold 2 is filled with concrete 4; then, as figure 1 As shown in middle e, the concrete 4 in the shaping mold 2 is maintained using the natural geothermal temperature of the soil, and after the concrete 4 in the shaping mold 2 has a certain strength, the shaping mold...

Abstract

The purpose of the present invention is to provide a method for prefabricating concrete piles, which is to prefabricate concrete piles on the spot at the construction site according to the specific needs of the project. mold, and sink the assembled shaping mold into the casing; 3) Insert steel bars into the shaping mold, then pour concrete into the shaping mold, and compact the concrete at the same time until it is filled with concrete; 4) Use the temperature of the soil to adjust the concrete After maintenance, the shaping mold is lifted out after having a certain strength, and the shaping mold is removed to form a prefabricated concrete pile body. The present invention also includes a construction method using prefabricated concrete piles, the steps of which are: 1) sinking the casing into a hole to a predetermined depth; 2) according to the properties of the soil layer and the upper load requirements, the pile is constructed by one of multiple methods. 3) Pour cement mortar into the casing, then put the prefabricated concrete pile body, and lift the casing.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to the construction technology of pile foundations and composite foundations. Background technique [0002] Prefabricated piles are one of the pile types commonly used in the field of construction in my country, mainly including concrete square piles, prestressed concrete pipe piles, steel piles, etc. Problems such as shrinkage and broken piles of cast-in-place concrete pile foundations. However, since prefabricated piles need to be manufactured in the factory, require special machinery and equipment, and have a long maintenance period, plus the transportation costs from the factory to the construction site, the construction cost of prefabricated piles is significantly higher than that of cast-in-place concrete piles. Moreover, the specifications and varieties of prefabricated piles produced by the factory are less, and the prefabricated piles required by many projects need to be le...
