Abstract

The invention provides a sealing device before a bituminous pavement water seepage test. The problems that 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 in the laying process of the sealing layer before the water seepage test are effectively solved. According to the technical scheme, the sealing device before the bituminous pavement water seepage test comprises a base, wherein an inner shell is arranged at the upper end of the base, a cylinder is fixed to 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 sleeves the outer side of the vertical rod; an annular plate is fixed to the outer edge of the inner shell, a plurality of containers penetrate through the annular plate, a plurality of discharging ports are formed in the lower side walls of the containers, square plates are arranged in the containers, the cylinder sleeves with a circular plate, a plurality of threaded pipes penetrate through the circular plate, screws are connected into the threaded pipes through threads, an outer cylinder is arranged on the outer side of the annular plate, and a gear ring is fixed to the inner side wall of the outer cylinder; a gear is fixed on the outer side of each container, a plurality of arc-shaped plates are hinged to the lower end of the annular plate, connecting rods are hinged to the edges of the lower end faces of the containers, and the other ends of the connecting rods are spherically hinged to the arc-shaped plates.

Description

technical field [0001] The invention relates to the technical field of dermatology, in particular to a sealing device before an asphalt pavement water seepage test. 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 sme...
