Paving device for pavement water seepage test sealing material

Abstract

The invention provides a pavement water seepage test sealing material laying device, which effectively solves the problem of low efficiency and poor sealing effect in the process of laying the sealing layer before the water seepage test, the trajectory of the sealing layer is not a perfect circle, the water seepage area cannot be guaranteed, and time-consuming The technical solution is to include a base, an inner shell on the upper end of the base, a cylinder on the upper side of the inner shell, a vertical rod inside the cylinder, a spiral groove on the vertical rod, and a rotary drum on the outer side of the vertical rod. There is an annular plate on the outer edge of the inner shell, and there are multiple containers running through the annular plate. There are multiple discharge ports on the lower side wall of the container. There is a square plate in the container, and a circular plate is set on the outer side of the cylinder. There are multiple threaded tubes, and there are screws in the threaded tubes; there is an outer cylinder on the outside of the annular plate, an upper gear ring on the inner wall of the outer cylinder, and a disc-shaped gear is fixed on the outer side of each container; there are multiple pressing pieces under the annular plate, and the inner side of the outer cylinder A lower ring gear is fixed, and a plurality of rotating shafts are arranged on the upper side of the annular plate, and bevel gears are arranged on the rotating shafts.

Description

technical field [0001] The invention relates to the technical field of pavement quality inspection, in particular to a pavement device for laying sealing materials for pavement water seepage tests. Background technique [0002] The water seepage test of asphalt pavement is an important index required by the national standard for asphalt pavement, and the water seepage performance of asphalt pavement can reflect the quality of the pavement. Before the test, it is necessary to clean the test area, and then apply a layer of sealing material on it, press the base of the water penetration meter on the ring of sealing material, and press the base of the instrument with the weight of the iron ring. Add water and observe the water seepage after a period of time. [0003] In the prior art, the commonly used sealing materials are butter and plasticine, which are mostly applied manually. There are some problems in the application, which are mainly reflected in the following aspects: ...
