Description

Technical Field

[0001] The utility model relates to the technical field of underground engineering, in particular to a waterproof structure between an underground structure of a main engine room of an ultragravity centrifuge and an auxiliary structure. Background Art

[0002] For the smooth operation of high-speed and large-capacity centrifuges, the foundation structure serves as the carrier. To ensure the dynamic characteristics of the ultra-gravity centrifuge, the main engine foundation structure is chosen to be arranged underground, and the auxiliary system is arranged in the shallow underground around it. The connecting channel is used between the two to meet the functional needs of pipeline connection and transportation.

[0003] Because the underground structure of the main engine room and the surrounding subsidiary structures not only have obvious structural differences (in underground height), but also the construction timing cannot be synchronized (the main engine room is constructed first). Therefore, there is a structural joint between the underground structure of the main engine room and the subsidiary structure, so it is extremely difficult to waterproof the connecting channel at the structural joint. Similar waterproofing solutions for underground structures in other fields all adopt waterproofing measures around the outside of the corresponding connecting structure joints, but the waterproofing measures are limited by the durability and difficulty of maintenance of waterproofing materials in a long-term underground environment; and because the structure size is relatively small and the outside is a soft convex foundation, it is difficult to achieve a sealing effect by grouting in the joint, so leakage is more common in this area.

DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0022] like Figure 1-4 As shown, the waterproof structure between the underground structure and the auxiliary structure of the main engine room of the ultragravity centrifuge has a passage 3 connected between the underground continuous wall 1 and the surrounding auxiliary structures 2, the underground continuous wall 1 is connected to the wall of the auxiliary structure 2, and the underground continuous wall 1 is provided with an inner lining wall 11 on the outside, and the inner lining wall 11 is provided with a flanged wall part 111 that wraps the end of the opening side of the underground continuous wall 1, and a wall protruding section is provided between the side wall of the flanged wall part 111 and the underground continuous wall 1, so that the flanged wall part 111 of the inner lining wall 11 of the main engine room structure is utilized to form the main engine room flanged structure, and then the flanged wall part 111 is used as the connection foundation for pouring the auxiliary structure 2; a water stop component 4 is provided between the side wall of the flanged wall part 111 and the wall of the auxiliary structure 2, and a rear connection part connected to the wall of the auxiliary structure 2 is provided on the water stop component 4.

[0023] In this embodiment, the lining wall 11 and the flanged wall portion 111 thereon are arranged at the connection position between the underground structure of the main engine room and the auxiliary structure 2. The size of the opening of the underground continuous wall 1 of the main engine room should take into account the size of the flanged wall portions 111 on both sides, that is, the opening width = the net width of the auxiliary structure 2 + 2 times the thickness of the lining wall 11 (such as Figure 1 As shown), opening height = net height of auxiliary structure 2 + 2 times the thickness of inner lining wall 11 (as shown Figure 2 The main engine room structure is wrapped along the underground continuous wall 1 through the inner lining wall 11, and protrudes 500mm from the outer wall surface of the underground continuous wall 1, forming a flanged wall part 111.

[0024] like Figure 1-3 As shown, in order to ensure the connection between the flanged wall part 111 and the underground continuous wall 1, the steel bars of the underground continuous wall 1 around the opening are retained, so as to simultaneously connect the end of the opening side of the underground continuous wall 1 and the flanged wall part 111 through the connecting steel bars 12. Thus, the flanged wall part 111 of the lining wall 11 can be effectively connected to the underground structure of the main engine room by connecting the connecting steel bars 12 and water stopping measures to form an integrated structure.

[0025] like Figure 1-2 As shown in Figures 4 and 5, the water stop component 4 is arranged at the connection between the flanged wall part 111 and the auxiliary structure 2, and the flanged wall part 111 is sealed around by the water stop component 4, so as to serve as internal waterproofing between the flanged wall part 111 and the auxiliary structure 2. In this embodiment, the water stop component 4 adopts a copper sheet for water stop, so it can not only adapt to the deformation of the structural joint, but also the water stop copper sheet has good connection performance with the newly poured concrete.

[0026] At the same time, when pouring concrete on the auxiliary structure 2, the vibration around the water-stop component 4 must be careful and comprehensive to avoid vibration leakage and damage to the water-stop copper sheet, thereby ensuring the connection effect between the water-stop and the concrete.

[0027] Specifically, in order to improve the waterproofing of the opening of the underground continuous wall 1 and the flanged wall part 111, a water stop strip 13 is added around the contact position between the opening side end of the underground continuous wall 1 and the flanged wall part 111. The water stop strip 13 can be a water stop strip that swells when exposed to water to ensure the waterproofing effect between the two.

[0028] like Figure 1-2 As shown in FIG. 4 , a caulking material 5 is provided between the side wall of the flanged wall portion 111 and the side wall of the wall of the auxiliary structure 2. Therefore, the function of the structural joint (realizing the separation of the two structures) can be met.

[0029] The sealing material 5 is preferably a closed-cell foam board.

[0030] In this embodiment, the wall of the auxiliary structure 2 includes side walls 21 on both sides, and the top plate 22 and the bottom plate 23 are connected to the two ends of the side walls 21, so that the opening of the underground continuous wall 1 is connected to the inside of the auxiliary structure 2 until the channel 3 is formed. After the construction of the auxiliary structure 2 is completed, waterproof materials are added to the outside as external waterproofing between the flanged wall part 111 and the auxiliary structure 2; the auxiliary structure 2 is provided with a waterproof barrier 6 on its wall relative to the outside of the channel 3, and the waterproof barrier 6 is attached to the outer wall surface of the auxiliary structure 2 and the flanged wall part 111 at the same time.

[0031] In this embodiment, the waterproof barrier 6 is a waterproof roll material attached to the wall. The waterproof barrier 6 is provided with an extension section attached to the outer wall surface of the underground continuous wall 1.

[0032] At the same time, a closed groove 14 is opened on the outer wall surface of the underground continuous wall 1, and a connecting part 61 embedded in the closed groove 14 is provided on the waterproof barrier 6; and a polymer is filled in the closed groove 14 to form a filling material 141 connected to the connecting part 61 of the waterproof barrier 6 in the closed groove 14.

[0033] The above embodiment is only a preferred technical solution of the present invention. Those skilled in the art should understand that the technical solutions or parameters in the embodiments can be modified or replaced without departing from the principle and essence of the present invention, and all should be included in the protection scope of the present invention.
