Shallow foundation hole forming and compacting qualification rate improving ramming head and use method thereof

Abstract

The invention provides a shallow foundation hole forming and compacting qualification rate improving ramming head and a use method thereof. The shallow foundation hole forming and compacting qualification rate improving ramming head comprises a ramming head body and a connecting rod, wherein grooves are formed in the upper side and the lower side of the ramming head body, the connecting rod is vertically and fixedly connected into the groove in the upper side of the ramming head body, and angle-shaped notches are formed in the groove walls of the grooves in the upper side and the lower side ofthe ramming head body. The ramming head and the method have the beneficial effects that mechanical hole cleaning and reaming are adopted, so that the working efficiency is improved; the grooves are formed in the upper side and the lower side of the ramming head body, and the angle-shaped notches are formed in the groove walls of the grooves, so that the hollow design of the upper side and the lower side of the ramming head body is formed, the purposes of reducing the weight of the ramming head and lowering the prefabrication cost are achieved, and the requirement for the power of an excavatoris reduced; and the hole forming and compacting qualification rate is improved by using the ramming head to perform hole cleaning and reaming.

Description

technical field [0001] The invention relates to the technical field of tamp heads, in particular to a tamp head for improving shallow foundation hole formation and compaction pass rate and a use method thereof. Background technique [0002] In the construction of the first phase of the Zhuzhou International Circuit, when setting up the concrete foundation of the safety facility fence and the protective net, it is necessary to use a rotary drilling auger to drill to a design depth of 5cm or less, and temporarily pile up the taken out soil in an open place nearby. , the initial hole is formed, and after the elevation test is qualified, the formed initial hole needs to be reamed and cleaned. However, the traditional manual reaming and cleaning has the problem of low efficiency. At the same time, the traditional manual reaming and cleaning, There are problems of foundation hole formation and low compaction pass rate. Contents of the invention [0003] The object of the presen...
