Description

Expansion joint drainage joint for wet working ground Technical Field The invention belongs to the technical field of building water conservancy dredging, and particularly relates to a hydrophobic joint of an expansion joint of a wet working ground. Background In workplaces such as factory building, workshop that the area is great, the ground needs to remain the expansion joint after the sclerosis in order to adapt to the demand of ground expend with heat and contract with cold, avoids ground to arch the fracture. For clean workshops, the terrace of the blank workshop obviously cannot be directly applied, so that secondary treatment is required to be carried out on the ground to improve the flatness, cleanliness and the like of the ground, for example, a food production workshop is required to carry out secondary pouring on the original blank concrete ground, such as self-leveling cement ground, at this time, in order to ensure that the secondarily poured ground still has expansion and contraction adaptability, a user can generally set expansion joints on the secondarily poured ground, and the secondarily poured expansion joints are communicated with the expansion joints of the blank ground up and down, so that the phenomenon of stacking faults between two layers of ground caused by dislocation of the expansion joints can be avoided, the secondarily poured ground and the blank ground are separated by unshelling, and the strength of the secondarily poured ground is influenced. For workshops with moist production environment, such as food processing workshops, aquaculture workshops, precision part cleaning workshops and the like, the workshop ground is easy to produce ponding and operation residues, expansion joints are easy to block, the expansion joints can lose the capability of absorbing ground expansion in the long term in the past, extrusion arching is caused when the ground expansion is caused, and the ground is damaged. Therefore, it is necessary to provide a ground expansion joint hydrophobic joint, which solves the above technical problems. Disclosure of Invention The invention aims to solve the technical problems that the expansion joint of the wet working ground is provided with a hydrophobic joint, and the problem that the expansion joint is disabled due to the fact that working dust and working residues of the wet working ground are flushed into the expansion joint by sewage is solved. In order to solve the technical problems, the invention adopts the technical scheme that the expansion joint of the wet working ground comprises a groove body extending along the axial direction of the expansion joint, lining plates respectively connected to the upper edges of two sides of the groove body, and a panel covering the upper surfaces of the groove body and the lining plates, one end of the panel is detachably and fixedly connected to the lining plates on one side of the groove body, the other end of the panel is movably abutted to the lining plates on the other side of the groove body, the lining plates are used for connecting the ground on two sides of the expansion joint, one sides of the two lining plates, which are far away from each other, are respectively connected with positioning strips, any positioning strip extends along the axial direction of the expansion joint, the panel is arranged between the two positioning strips, an expansion gap is reserved between one end of the panel movably abutted to the lining plates and the adjacent positioning strips, the positioning strips are embedded on the ground, and the top surface of the positioning strips is not higher than the ground. As a preferable scheme, the positioning strip is in a groove-shaped structure of a lath, a pipe fitting or a back-off, is connected with or directly welded or integrally formed on the lining plate through a connecting piece, and the connecting piece is any one of a bolt, a clamping piece, a rivet and a magnet. As a preferable scheme, when the positioning strip and the lining plate are integrally formed, the edge of the lining plate is at least bent vertically upwards to form a vertical edge, bent vertically in a direction away from the panel to form a top edge, and bent downwards to form an inclined or vertical flanging. As a preferable scheme, when the positioning strip is connected or welded on the lining plate through the connecting piece, the edge of one side of the lining plate far away from the groove body is welded or integrally formed with a plug board which extends obliquely downwards or vertically downwards, and a plurality of through holes which are arranged along the axial direction of the groove body in a discrete manner are formed in the plug board. Preferably, the surface of the panel facing the lining plate is a rough surface, and a water supply flow channel is arranged between the panel and the lining plate. As a preferable scheme, two baffle plates are respectively connected to the bottom surfaces of th
