Problems solved by technology

[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

Embodiment Construction

[0015] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0016] In order to facilitate the understanding of the ram head for improving shallow foundation hole formation and compaction pass rate provided by the embodiment of the present invention, firstly explain the application scenario of the shallow foundation hole formation and compaction pass rate tamp head provided by the embodiment of the present application. The tamp head provided in the example to improve shallow foundation hole formation and compaction qualification rate is used to ream and clean the initial hole formed by rotary drilling and auger. At present, the traditional artificial hole rea...

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.
