Abstract

A trapezoidal inserting and connecting pile wall device comprises a concave trapezoidal head drilling machine and a convex trapezoidal head drilling machine. A plurality of concrete concave trapezoidal head piles at the interval of one convex trapezoidal head pile are manufactured; and when the strength of the concrete of the concave trapezoidal head piles on the two sides reaches a certain degree, one concrete convex trapezoidal head pile is manufactured within the interval between every two concave trapezoidal head piles through the convex trapezoidal head pile drilling machine according to a work manner of the above convex trapezoidal head pile drilling machine, and in this way, a pile wall formed in the manner that the plurality of concrete concave trapezoidal head piles and the concrete convex trapezoidal head pile between every two concave trapezoidal head piles are mutually inserted and connected is formed and used for soil retaining and leakage prevention of a building foundation.

Description

technical field [0001] The invention relates to a pile wall, in particular to a trapezoidal plug-in connection pile wall used in building foundation engineering. Background technique [0002] At present, the pile body formed by other types of cement-soil mixing pile machines is a combination of a plurality of cement-soil cylinders, and it is impossible to manufacture a pile wall that is inserted and connected. Contents of the invention [0003] The invention provides a trapezoidal insertion and connection pile wall equipment capable of manufacturing trapezoidal insertion and connection pile walls. [0004] The present invention is achieved through the following technical solutions: [0005] A trapezoidal plug-in connection pile wall equipment includes a concave trapezoidal head drilling machine and a convex trapezoidal head drilling machine. [0006] The structure of the concave trapezoidal head drilling machine includes: the lower end of the drill rod 1 is fixed on the ...
