Abstract
The special anti-leakage bolt for the sewage and water purifying concrete engineering comprises a rod I with external threads at two ends, and a curved surface water stopping disc is welded in the middle of the rod I. Compared with the prior art, because the utility model discloses a stagnant water dish is the curved surface dish, and is big with the faying face of concrete, can change the trend of infiltration simultaneously, and the resistance of increase infiltration has avoided the emergence of dirty, water purification concrete engineering seepage phenomenon.
Description
Technical Field
The utility model relates to a stagnant water screw rod, especially a special bolt of dirty, water purification concrete engineering antiseep.
Background
The water stopping discs of the water stopping screw rods sold in the market at present are all plane discs, the combination area of the water stopping discs of the plane disc water stopping screw rods and concrete is small, the combination surface is simple, and water seepage is easy to occur. Therefore, the design of the anti-seepage bolt special for the sewage and water purification concrete engineering, which is not easy to seep water, is a technical problem to be solved at present.
Disclosure of Invention
The utility model aims to solve the technical problem that a special bolt of dirty, water purification concrete engineering antiseep is provided.
The technical proposal of the utility model for solving the technical problem is that:
the special anti-leakage bolt for the sewage and water purifying concrete engineering comprises a rod I with external threads at two ends, and a curved surface water stopping disc is welded in the middle of the rod I. When in use, the groove of the curved surface water stopping disc faces the water inlet direction.
As a preferred scheme of the utility model, the curved surface stagnant water dish be [ type stagnant water dish.
As the utility model discloses an optimal scheme still includes two poles II of one end outband screw thread one end in-band screw thread blind hole, and the internal thread blind hole of pole II matches with the external screw thread of pole I, and two poles II are adorned at the both ends of pole I respectively soon, and the length of pole I is less than or equal to the thickness of dirty, water purification concrete engineering wall or pool wall, and the cover is equipped with the mountain type card on pole II, is equipped with the nut at the external screw thread top spin of pole II.
As an optimized scheme of the utility model, pole II comprises external screw thread section and polished rod section, and the diameter of polished rod section is greater than the diameter of external screw thread section, the internal thread blind hole at the tip of polished rod section, processing has outer hexagonal on the polished rod section of polished rod section and external screw thread section joint portion.
As an optimized scheme of the utility model, there is the outward flange at the tip of polished rod section, and the cover is equipped with toper plastic sheath on pole II, has the tang at the tip of toper plastic sheath, and the diameter of tang matches with the diameter of outward flange.
As an optimized proposal of the utility model, the rod II is a reusable antirust chromium-plated rod.
Compared with the prior art, because the utility model discloses a stagnant water dish is the curved surface dish, and is big with the faying face of concrete, can change the trend of infiltration simultaneously, and the resistance of increase infiltration has avoided the emergence of dirty, water purification concrete engineering seepage phenomenon.
