Abstract
The utility model discloses a temporary plugging wall for an underground reinforced concrete box culvert structure. The temporary plugging wall comprises a temporary plugging wall concrete structure and is characterized in that a thin film isolation layer is attached to the end face of a pre-built box culvert main structure, and the temporary plugging wall concrete structure and the pre-built box culvert main structure are connected through a reinforced concrete connecting block. Embedded connecting reinforcements are arranged at the end of the pre-built box culvert main structure, the reinforced concrete connecting block is connected with the pre-built box culvert main structure through the embedded connecting reinforcements, and the reinforced concrete connecting block is connected with the temporary plugging wall concrete structure through connecting reinforcements. The temporary plugging wall has the advantages that not only can construction be performed simply, rapidly and conveniently, but also water stops are protected effectively.
Description
Technical field
When the utility model relates to the segmented construction of cut and cover tunneling cast-in-situ steel reinforced concrete underground chamber structure (comprising roads and tunnels structure etc.), be arranged at the interim block wall of end.
Technical background
In underground chamber when construction, according to the requirement of execution conditions and construction speed, often need carry out segmented construction to underground structure box culvert, in the end of implementing box culvert in advance the interim block wall of steel concrete is set, and block wall cut to continue again to apply when follow-up construction.
When former method is met this type of situation, processing method generally has two kinds of methods: the one, and in box culvert main body reinforced concrete member such as top, base plate and side wall, close on deformation joint and reserve the stressed main reinforcement monobloc cast of interim block wall concrete, the end deformation joint adopts and buries waterstop in the measures protections such as plain concrete and back-up sand, pastes parts such as waterstop outward, top, box culvert cross section, base plate and side wall end inner peripheral arrange plain concrete as load transfering strip (burying waterstop in avoiding), the outer subsides of outside back-up sand protection, in bury waterstop; The 2nd, all adopt plain concrete protection paste outward, in bury waterstop (all the other are with above-mentioned).Above-mentioned job practices problem is as follows: the one, and block wall cuts the comparison difficulty; The 2nd, as adopting the back-up sand method, building the plain concrete load transfering strip sets up template and need dodge waterstop, not only construction inconvenience but also the waterstop quality also had certain influence, or as adopt whole plain concretes to build the protection waterstop, and when cutting, will influence the waterstop quality and then influence waterproof effect; The 3rd, interim block wall outsourcing waterproof is difficult enforcement.
The utility model content
The purpose of this utility model is to provide a kind of underground reinforced concrete box culvert structure interim block wall, further reduces to cut block wall to building the influence of box culvert structure when continuing construction, and only the contiguous block that need cut between block wall and agent structure gets final product.Adopt this method not only can simple and convenient rapid construction, and more effective to the waterstop protection.
To achieve these goals, technical solutions of the utility model are: the interim block wall of a kind of underground reinforced concrete box culvert structure, comprise interim block wall concrete structure, it is characterized in that building earlier the box culvert agent structure end face film separation layer of applying ointment or plaster, interim block wall concrete structure and building earlier between the box culvert agent structure connects by contiguous block.Formerly build box culvert agent structure end and be provided with built-in connection, contiguous block by described built-in connection with build the box culvert agent structure earlier and be connected, contiguous block also is connected with interim block wall concrete structure by connector.Build earlier the box culvert agent structure also be provided with in buried rubber fastening band, external labeling type rubber fastening band and the pre-pipe laying of shearing bar, interim block wall concrete structure and build earlier and PVC is set between the box culvert agent structure fills block is arranged in and builds box culvert agent structure outer buried rubber fastening band, external labeling type rubber fastening band and the pre-pipe laying of shearing bar earlier and all be positioned at described PVC and fill block.Described contiguous block is the steel concrete contiguous block, and described built-in connection is pre-buried connecting reinforcement, and described connector is connecting reinforcement.Described contiguous block adopts the steel member, and wherein built-in connection adopts embedded nut, and connector adopts bolt.
At first interim block wall concrete structure is carried out piecemeal cutting, cuts can unload behind the steel concrete contiguous block and clear before the follow-up construction, also effectively reduce when having improved efficiency of construction and cut block wall to the influence of agent structure; Secondly PVC filling block is made whole removal and get final product, the waterstop quality is not had influence substantially.Then can carry out follow-up box culvert construction according to conventional method.Advantage of the present utility model is: not only can simple and convenient rapid construction, and also more effective to the waterstop protection.

The specific embodiment
Among the figure: 1. interim block wall concrete structure; 2. block wall steel bar stress; 3. pre-buried connecting reinforcement; 4. PVC fills block; 5. build the box culvert agent structure earlier; 6. steel concrete contiguous block; 7. paste waterproof roll outward; 8. buried rubber fastening band in; 9. external labeling type rubber fastening band; 10. the pre-pipe laying of shearing bar; 11. shearing bar; 12. film separation layer; 13 is the connecting reinforcement between steel concrete contiguous block and the interim block wall concrete structure.
Below in conjunction with accompanying drawing the utility model is further described:
The interim block wall of a kind of underground reinforced concrete box culvert structure, comprise interim block wall concrete structure 1, it is characterized in that building earlier the box culvert agent structure 5 end faces film separation layer 12 of applying ointment or plaster, interim block wall concrete structure 1 and building earlier between the box culvert agent structure 5 connects by steel concrete contiguous block 6.Formerly build box culvert agent structure 5 ends and be provided with pre-buried connecting reinforcement 3, steel concrete contiguous block 6 by described pre-buried connecting reinforcement 3 with build box culvert agent structure 5 earlier and be connected, steel concrete contiguous block 6 also is connected with block wall concrete structure 1 temporarily by connecting reinforcement 13.Build earlier the box culvert agent structure also be provided with in buried rubber fastening band 8, external labeling type rubber fastening band 9 and the pre-pipe laying 10 of shearing bar; interim block wall concrete structure 1 and build earlier and PVC is set between the box culvert agent structure 5 fills block 4; build earlier the box culvert agent structure outer in buried rubber fastening band 8, external labeling type rubber fastening band 9 and the pre-pipe laying 10 of shearing bar all be positioned at described PVC and fill block so that protect above-mentioned in buried rubber fastening band 8, external labeling type rubber fastening band 9 and the pre-pipe laying 10 of shearing bar.
The utility model is a kind of interim block wall design and construction method, and its implementation method step is as follows:
