Abstract

The invention discloses a multi-bit convolution punching / tamping engineering groover which comprises symmetrically-arranged stroke drill pipes and a positioning beam, wherein the lower part of the positioning beam is provided with a main drill bit which can make convolution motion driven by the stroke drill pipes, a tool array seat is fixed on the lower end face of the positioning beam and provided with a tool array with alloy tool tips, and a punching / tamping hammer which can move up and down is arranged above the positioning beam. Under the punching and tamping actions of the punching / tamping hammer, the main drill bit drills rock soil to form a plurality of drill holes, and the surplus rock soil is broken by the tool array through the punching and tamping actions of the punching / tamping hammer. By using the groover disclosed by the invention, a groove can be formed at a time, and the wall of the formed groove is smooth and neat, therefore, the construction requirements are completely satisfied, and the performance index of the groover disclosed by the invention completely exceeds that of groovers of the same kind. The groover disclosed by the invention carries out drilling, punching and tamping simultaneously by using multiple drill bits and the punching / tamping hammer; and the operating state of the groover is adjusted according to the mechanical properties of rock soils of stratums, i.e. for soft stratums, an drilling is mainly performed, for hard stratums, punching is mainly performed, and for ultrahard stratums, tamping is mainly performed, thereby efficiently directly completing grooving on complex stratums.

Description

technical field

[0001] The invention relates to a basic engineering construction machine, in particular to a slotting machine for multi-drill rotary punching and smashing engineering. Background technique

[0002] In water conservancy, transportation, construction and other engineering fields, it is necessary to build various underground continuous walls under different geological conditions. However, it is still a very difficult and urgent problem to open deep grooves on hard rock formations to build various underground continuous walls. The problem.

[0003] Recalling that the relevant domestic units have done a lot of work in the construction technology of the underground diaphragm wall, and have made some progress, mainly using the following equipment and technology:

[0004] 1. Water-jet underground wall-forming technology: the main principle is to use large-flow, high-pressure water jets to punch the soil layer, cut through the blade at the bottom of the trough-formin...
