A sand filling instrument for detecting large-thickness and wide-width water stability layers and its construction method

Abstract

The present application relates to a sand filling instrument for detecting large-thickness and wide-width water stability layers and its construction method. The sand filling instrument includes a sand storage tank and a base plate. The base plate and the sand storage tank are jointly provided with a pressing component. The assembly includes a limit cylinder, an abutment plate and a bottom support ring plate; the bottom support ring plate is set on the outer edge of the sand storage cylinder, the limit cylinder is set on the upper surface of the base plate, and the lower surface of the abutment plate is provided with a card connection groove; the base plate and the sand storage cylinder are also jointly provided with an anti-bias assembly, the anti-deflection assembly includes a tie belt, a locking screw and a locking cylinder; the locking cylinder is rotatably arranged on the tie belt One end in the length direction, one end of the pair of pull ties is set on the outer wall of the sand storage cylinder, the clamping screw is set on the upper surface of the base plate, and the clamping screw is threaded into the inner cavity of the locking cylinder; the construction method includes : Datum positioning, cylinder reinforcement and detection experiment; this application has the effect of effectively ensuring the position stability of the sand storage cylinder on the base plate and improving the detection accuracy of the sand filling instrument.

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 stable layers and a construction method thereof. Background technique [0002] The water stable layer generally refers to the road base formed by the paving of cement and gravel. In the construction of highways, the water stabilization layer, as the base layer of the highway, is mostly divided into two methods: layered laying and one-time paving forming. Among them, most of the large-thickness and wide-width water-stabilizing layers adopt one-time paving forming technology to reduce the phenomenon of uneven internal force and large deviation of excitation force in the water-stabilizing layer. After the laying and compaction of the water stabilization layer, the construction workers mostly measure the compaction degree of the water stabilization layer by the sand filling method through the sand ...

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
