Embodiment Construction

[0031] Such as Figure 1 to Figure 8 A kind of light-duty artificial power coring machine used for engineering geological survey is shown, comprising drill bit 1, coring device 2 and drill pipe 3 connected successively from bottom to top, and drill bit 1 and coring device 2 are threadedly connected, and taking The core device 2 is threaded with the drill rod 3, the drill bit 1 is a cylindrical hollow iron pipe, and the bottom end of the drill bit 1 is a cutting edge with a thin bottom and a thick top, so as to facilitate the drilling of the drill bit 1 in the soil layer. The drill pipe 3 is also equipped with a casing 4 during use. The coring device 2 is composed of iron round pipes that can be split in half. The bottom of the round pipe is connected with a replaceable core bit 1. When the drill bit 1 is damaged, it can be replaced in time. After the corer 2 is filled with soil cores, it is taken out by the drill pipe 3 After unloading the drill bit 1 and opening it, the soil...

Abstract

The invention discloses a light manual power core taking machine for engineering geological investigation. The light manual power core taking machine comprises a drilling bit, a core taking device anda drilling rod which are sequentially connected from bottom to top. The core taking machine further comprises a heavy punch power assembly. The heavy punch power assembly is detachably connected to the top end of the drilling rod. The heavy punch power assembly is used for completing labor power lifting to strike drilling, and thus the drilling bit and the core taking device take an undisturbed sample on the soil layer. The core taking machine is simple in structure, light and convenient to operate, for simple exploration, the tunneling depth is large, the price is low, light dynamic soundingin-situ testing work can be completed, and the engineering geological investigation can be carried out beneficially and smoothly.

Description

technical field [0001] The invention relates to a dynamic soil layer coring device, in particular to a light manual power coring machine used for engineering geological survey. Background technique [0002] In recent years, with the rapid development of engineering construction in mountainous areas (such as mountainous highways), survey tasks have gradually increased. Generally, there are three common solutions for mountain depressions and simple strata: [0003] (1) Use ordinary XY-100 drilling rig for drilling. Ordinary XY-100 drilling rig is composed of machine head, diesel engine, base, winch, drilling tower, drill pipe, core pipe, casing, water pump, water pump, etc. The mechanical equipment is heavy and the whole set weighs 1 to 2 tons, which is not convenient Handling is time-consuming and laborious. [0004] (2) The commonly used simple exploration equipment is the Luoyang shovel, which consists of a shovel head, a counterweight rod and an extension rod. When in ...
