Drilling coring machine for highway pavement detection

Abstract

The invention relates to a drilling coring machine for highway pavement detection. The drilling coring machine comprises a movable frame and a base; a bracket, a handle and vertical columns are connected and fixed to the top of the base from left to right; and the movable frame and the vertical columns constitute an up-down sliding structure through a fixed frame and a screw rod fixedly connectedto the bottom of a rotating handle. The drilling coring machine for highway pavement detection has the beneficial effects that by adopting the structures of a first side plate, a second side plate anda rubber baffle, a barrier can be formed on the outer circle of a drilling tube, noise generated when the drilling tube works is blocked, and thus the effect of lowering the noise hazard is achieved;the second side plate can be conveniently rotated to be opened, and thus the working efficiency of constructors is not affected; and through the design of a visual window, a worker can observe the drilling tube outside the first side plate and the second side plate, so that the more convenient effect is achieved.

Description

technical field [0001] The invention relates to the technical field of highway pavement detection, in particular to a drilling and coring machine for highway pavement detection. Background technique [0002] Highway is a modern term. It is a public road where cars can be driven. Many vehicles such as cars, bicycles, rickshaws, and horses, as well as pedestrians can walk. Early roads had no restrictions, and most of them were simple roads. Later, different roads had different restrictions; The traffic is increasingly developed, and there are more and more roads with restricted use, especially some roads are specially used for cars, and the type of expressway has been developed, which is specially used for the whole closed use of cars; according to the rough division of road structure, it can be divided into For the base layer and the surface layer, no matter it is the base layer or the surface layer, after the construction is completed, it is necessary to take a sampling test...
