The following describes embodiments of the present invention in detail with reference to the accompanying drawings, and the embodiments and specific construction processes of the present invention are given by implementing the embodiments on the premise of the technical solution of the present invention, but the scope of protection of the present invention is not limited to the following embodiments.
As shown in fig. 1-3, the first steel member M1 and the second steel member M2 are prefabricated workpieces with working cavities having upper openings, and are assembled and connected together by adopting a bolt connection mode during construction, wherein the assembly operation is an underwater operation, and in order to maintain a dry environment in the working cavities, a water stopping structure is required to be arranged at the bolt connection position to prevent water from leaking along bolt holes (i.e. reserved holes).
Specifically, when the first steel member M1 and the second steel member M2 are prefabricated, two coaxial equal-diameter preformed holes 1 should be formed at the preset connection positions of the first steel member M1 and the second steel member M2, and the inner diameter of each preformed hole 1 is adapted to the outer diameter of the screw of the fastening bolt 2. Then, two circular rubber plates 3 are selected as first water stopping pieces, and the outer diameter of each circular rubber plate 3 is larger than the inner diameter of each reserved hole 1, so that the circular rubber plates can cover the reserved holes 1 to form a first water stopping structure. In order to fix the rubber plate 3, a round steel plate with a through hole in the center is selected as the pressing plate 4 to cover the outer side of the round rubber plate 3 and is fixed by the screw 5. The circular rubber sheet 3 and the pressing plate 4 are provided on opposite sides of the steel member assembly surface. For convenient installation, a plurality of screw adaptation holes are evenly formed in the periphery of each pressing plate 4, and threaded holes matched with the threaded ends of the screws 5 are formed in the steel members.
The above-mentioned fastening bolt 2 is composed of a bolt head and a screw rod, the free end of which is fitted with an end nut 6, and which is provided with an annular cutting edge 7 (i.e., piercing end) having a diameter smaller than the inner diameter of the preformed hole 1 for piercing the circular rubber sheet 3 (i.e., first water stop). In order to further improve the water stopping effect, a second water stopping member 8 is further provided between the fastening bolt 2 and the central through hole of the pressing plate 4. Specifically, the second water stop 8 is an annular structure formed by winding a water-swelling rubber water stop belt (with a circular cross section), and the inner diameter of the annular structure is smaller than the outer diameter of the fastening bolt 2, and the outer diameter is larger than the inner diameter of the central through hole of the pressing plate 4. After the second water stop member 8 is pressed and deformed, the second water stop member can be extruded and stuffed in a gap between the central through hole of the pressing plate 4 and the screw rod of the fastening bolt 2, so as to form a second water stop structure. The second water stop structure has two parts, one part is arranged at the bolt head of the fastening bolt 2, and the other part is arranged at the end nut 8 of the fastening bolt 2. In order to facilitate the formation of the second water stop structure, the inner diameter of the central through hole of the pressing plate 4 should be slightly larger than the inner diameter of the preformed hole 1.
During installation, firstly, a circle of water-swelling rubber water stop belt is wound on a screw rod at a position close to the bolt head of the fastening bolt 2, then the cutting edge 7 pierces the circular rubber plate 3 of the first steel member M1 to enable the screw rod to enter the reserved hole 1, then the circular rubber plate 3 of the second steel member M2 is pierced to penetrate out of the reserved hole 1, afterwards, a circle of water-swelling rubber water stop belt is wound on the screw rod at one end of the cutting edge 7, finally, the end nut 6 is screwed, so that the first steel member M1 and the second steel member M2 are fastened and connected together, in the process, the water-swelling rubber water stop belts at two ends of the screw rod are all extruded and stuffed into a gap between the central through hole of the pressing plate 4 and the screw rod of the fastening bolt 2, so as to form a second water stop structure, and installation is completed.
According to the invention, the cutting edge 7 of the screw rod passes through the two round rubber plates 3 in the first steel member M1 and the second steel member M2 to form first water stop, and then the water-swelling rubber water stops at the two ends of the screw rod are deformed under pressure to form second water stop by screwing the end nuts 6, so that the operation is convenient, the sealing effect is good, water inflow in a working cavity of the steel member can be effectively prevented, a dry working environment is maintained, the construction safety is ensured, and the working efficiency is improved.
It should be noted that, in the description of the present invention, terms such as "front", "rear", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element to be referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention.
