Sand filling instrument for detecting large-thickness and wide-width water-stable layer and construction method of sand filling instrument

Abstract

The invention relates to a sand filling instrument for detecting a large-thickness and wide-width water-stable layer and a construction method of the sand filling instrument. The sand filling instrument comprises a sand storage barrel and a base plate, wherein the base plate and the sand storage barrel are jointly provided with an abutting assembly, the abutting assembly comprises limiting air cylinders, abutting plates and a bottom supporting ring plate, the bottom supporting ring plate is arranged on the outer edge of the sand storage barrel, the limiting air cylinders are arranged on the upper surface of the base plate, clamping grooves are formed in the lower surfaces of the abutting plates, the base plate and the sand storage cylinder are further jointly provided with an anti-deviation assembly, the anti-deviation assembly comprises an opposite-pull tying belt, a clamping lead screw and a locking cylinder, the locking cylinder is rotationally arranged at one end of the opposite-pull tying belt in the length direction, one end of the opposite-pull tying belt is arranged on the outer side wall of the sand storage cylinder, the clamping lead screw is arranged on the upper surface of the base plate, and the clamping lead screw is in threaded fit with an inner cavity of the locking cylinder. The construction method comprises the steps of datum positioning, barrel reinforcing and detection experiment. The sand filling instrument has the advantages that the position stability of the sand storage cylinder on the base plate is effectively guaranteed, and the detection precision of the sand filling instrument is improved.

Description

technical field [0001] The application relates to the field of sand filling instruments, in particular to a sand filling instrument for detecting large-thickness and wide-width water stability layers and a construction method thereof. Background technique [0002] The water stability layer generally refers to the road base layer formed by cement gravel paving. In the construction of highways, the water-stabilized layer is used as the base layer of the highway, and most of them are divided into two methods: layered laying and one-time paving. Among them, the one-time paving technology is mostly used for large-thickness and wide-width water-stabilized layers to reduce the phenomenon of uneven internal force and large deviation of excitation force in the water-stabilized layer. After laying and compacting the water-stabilized layer, construction workers mostly measure the degree of compaction of the water-stabilized layer with the sand filling method using a sand filling instr...

Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that when the sand filling instrument is operating outdoors, the position stability of the sand storage cylinder on the base plate is easily reduced by strong wind blowing, and then it is easy to cause the sand storage tank to loosen relative to the base plate. The phenomenon of deflection, which greatly affects the detection accuracy of the sand filling instrument
