Construction method of concrete pile

Abstract

According to the construction method of the concrete pile provided by the invention, the technical characteristic that the bearing capacity is improved by packing and compacting at the pile end is utilized, various devices can be used in the construction process, various materials are compatible, and the construction method is particularly suitable for engineering requirements of low underground water content and harder soil texture; the method comprises the following steps: 1) sinking a pile casing to a set depth in various ways, or directly forming a hole in a soil body; (2) filling coarse aggregate in batches, and ramming or extruding in a hammering or static pressure manner; (3) filling a set amount of coarse aggregate, and tamping or extruding; the construction method comprises the following steps of (1) filling fine aggregate in batches and tamping or extruding in a hammering or static pressure mode, (2) filling the fine aggregate in a set amount and tamping or extruding to reinforce and compact a soil body in a certain depth and within a certain range below a pile end, and (3) constructing a cast-in-place concrete pile body or a precast concrete pile body according to geological conditions and design requirements.

Description

technical field [0001] The invention relates to a pile foundation construction technology, in particular to a construction method of a concrete pile. Background technique [0002] A pile foundation technology is disclosed in Patent No. ZL98101041.5, which includes a composite carrier and a concrete pile body. , and form a composite carrier at the pile end through the three-strike penetration control standard, so that the upper load can be effectively transmitted through the pile and the composite carrier under the pile to the better bearing layer, thereby improving the bearing capacity of the pile. It has the advantages of high bearing capacity and economical cost. However, the filler used in this technology is construction waste. First, the material is relatively simple, and other nearby materials cannot be fully utilized. Second, with the development of construction, the use of clay bricks is becoming less and less, and it is more and more difficult to find construction w...

Problems solved by technology

However, the filling material used in this technology is construction waste. First, the material is relatively single, and other nearby materials cannot be fully utilized. Second, with the development of construction, clay bricks are used less and less, and it becomes more and more difficult to find construction waste. The cost is also increasing, and the third is that it is easy to cause secondary pollution of construction waste
