Pavement water seepage test sealing material laying device

Abstract

The invention provides a pavement water seepage test sealing material laying device. The problems that in the sealing layer laying process before a water seepage test, efficiency is low, the sealing effect is poor, the track of a sealing layer is not a perfect circle, the water seepage area cannot be guaranteed, and time and labor are wasted are effectively solved. According to the technical scheme, the device comprises a base, an inner shell is arranged at the upper end of the base, a cylinder is arranged on the upper side of the inner shell, a vertical rod is arranged in the cylinder, a spiral groove is formed in the vertical rod, and a rotating cylinder is arranged on the outer side of the vertical rod in a sleeving mode; an annular plate is arranged on the outer edge of the inner shell, a plurality of containers penetrate through the annular plate, a plurality of discharging openings are formed in the lower side walls of the containers, square plates are arranged in the containers, the outer side of a cylinder is sleeved with a circular plate, a plurality of threaded pipes penetrate through the circular plate, and threaded rods are arranged in the threaded pipes; an outer cylinder is arranged outside the annular plate, an upper gear ring is arranged on the inner side wall of the outer cylinder, and a disc-shaped gear is fixed on the outer side of each container; a plurality of pressing sheets are arranged below the annular plate, a lower gear ring is fixed on the inner side of the outer cylinder, 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 dermatology, in particular to a pavement device for pavement water seepage test sealing material. 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: [0004] 1. The trajectory of...
