Embodiment Construction

[0022] Such as figure 1 and figure 2 As shown, a composite material pile according to the embodiment of the present invention includes a cement-soil pile 1 , and a stiffening tube 2 is arranged inside the cement-soil pile 1 , and the stiffening tube 2 is arranged on the upper part of the cement-soil pile 1 . The material of the cement-soil pile 1 is cement-soil, and the cement content in the cement-soil is 15% and the water content is 40%.

[0023] The stiffening pipe 2 is a PE (polyethylene) pipe, HDPE (high density polyethylene) double-wall corrugated pipe, or a polyethylene winding pipe. Its advantages mainly include:

[0024] (1) It has excellent corrosion resistance and long service life. PE pipes can resist the corrosion of various chemical media. The chemical substances in the soil will not cause any degradation to the pipes. Under the condition of 20°C, the pipes can still maintain the minimum required strength (circumference) of 10MPa after 50 years. Polyethylene...

Abstract

The invention relates to a composite pile and a manufacturing method thereof. The composite pile comprises a cement-soil pile. A stiffening pipe is arranged in the cement-soil pile, and the stiffening pipe is arranged at the upper part of the cement-soil pile. The cement-soil pile is made of cement soil, wherein the cement content of the cement soil is 15 percent, and the water content is 40 percent. The composite pile provided by the invention has the beneficial effects that the composite pile plays a role of looping the cement-soil pile, and thus, while the bearing capacity of the cement-soil pile can be remarkably improved, the action of the vertical bearing capacity cannot be borne by the cement-soil pile. Discovered by field implementation, the composite pile is good in economic effect and popularization condition.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a composite material pile and a manufacturing method thereof. Background technique [0002] The cement-soil mixing method was first successfully developed in the United States, which is called Mixed-In-Pile (MIP method for short). This method was introduced in Japan in 1953, and it began to devote itself to this research in the late 1960s. In 1974, it was developed into a cement mixing solidification method. In 1977, the General Institute of Construction Research of the Ministry of Metallurgy and the Water Transport Planning and Design Institute of the Ministry of Communications carried out indoor experiments and mechanical development in China. In 1981, it was successful in the reconstruction and expansion of the cooking pot of Tianjin Paper Mill. [0003] In the 1970s, Japan formed a foundation pit enclosure system with overlapping cement-soil mixing pile walls inser...
