In the invention, after the top cover 8 is detached, the travelling crane 28 arranged above the machine room 6 in a crossing way can directly lower the corresponding lifting rope from the top of the machine room 6 so as to be used for hoisting and fixing the winch hoist 3, the accident gate 1 and the like, thereby facilitating the hoisting operation such as installation, maintenance, replacement and the like. Moreover, after the structures such as the steel structure side wall 15 and the like are further disassembled, the machine room 6 and the two sides of the whole building structure formed by the bent frames below can form a through hoisting channel, and then the fixed hoisting hoist 3 and the accident gate 1 can be hoisted in and out through the channel without hoisting the fixed hoisting hoist 3 and the accident gate 1 in and out from the top of the machine room 6, so that the maximum hoisting height of the crane 28 can be effectively reduced, the height of the crane 28 can be effectively reduced, and the cost is saved.
In addition, in order to facilitate the hoisting of the top cover 8, the top cover 8 is preferably arranged to be a steel structural member; the top cover 8 can be conveniently manufactured into an integrated structure, and is lighter and more convenient and convenient to construct relative to a reinforced concrete structure.
In addition, because the through groove 14 is formed in the bottom plate 13, when the hoisting operation is not performed, the detachable steel cover plate 16 is arranged at the corresponding gap position of the through groove 14 to cover the corresponding position of the through groove 14, so that a large-area hollow structure cannot be formed on the bottom plate 13, and the potential safety hazard is reduced. More specifically, a first embedded angle steel 17 may be disposed at an edge of the through groove 14 of the bottom plate 13, and a step for mounting the steel cover plate 16 in an overlapping manner is formed by the first embedded angle steel 17; therefore, the steel cover plate 16 can be directly lapped and installed on the corresponding first embedded angle steel 17, and the steel cover plate 16 only needs to be taken out upwards during disassembly.

Thus, when the hoisting operation is required, the corresponding steel beam 19 is also detached at the same time. Of course, the steel beams 19 may be of a construction such as i-steel, channel steel or steel box beams.
More specifically, the size, number, and the like of the steel beams 19 may be set appropriately according to actual conditions, and at least one steel beam 19 may be provided at intervals in the vertical direction at the edge portions of the left and right sides of the upstream side wall 9 and the downstream side wall 10. As shown in the attached drawings, two steel beams 19 are provided at intervals in the vertical direction; when the vertical heights of the upstream side wall 9 and the downstream side wall 10 are relatively high, a greater number of steel beams 19 may be provided at intervals.
In addition, for a specific installation structure of the steel beam 19, the present invention may be arranged such that both ends of the steel beam 19 are connected to steel embedments 20 embedded in the upstream side wall 9 and the downstream side wall 10, respectively, by bolts. The steel embedded parts 20 are embedded in the upstream side wall 9 and the downstream side wall 10 when the construction of the upstream side wall 9 and the downstream side wall 10 is performed. Specifically, the upstream side wall 9 and the downstream side wall 10 are of a reinforced concrete structure, the steel embedded part 20 includes an external steel member 21 and embedded steel bars 22, the embedded steel bars 22 are embedded in the corresponding reinforced concrete structure and connected with internal steel bars, and one end of each embedded steel bar 22 is welded to the external steel member 21 outside the reinforced concrete structure; the outer steel members 21 are connected to the ends of the steel beams 19 by bolts. During the construction of the upstream side wall 9 and the downstream side wall 10, the joint bars 22 are welded or bound to the corresponding reinforcing bars in the reinforced concrete, and then concrete pouring is performed to embed the joint bars 22 of the embedded steel parts 20 and connect the embedded steel parts with the steel beams 19 through the external steel parts 21. As shown in fig. 8, a plurality of bolt holes are respectively provided in the outer steel member 21 and the steel beam 19, and then are connected by bolts.
