Description
Technical field
The utility model is related to building top-down method building technology fields, the more particularly to full bag for contrary sequence method building
Water proof structure structure.
Background technology
In underground engineering, reinforced concrete structure is still occupied an leading position.Although underground waterproof concrete takes certain technical measures, add
Add various additives, but crack after constructing still is difficult to avoid that, therefore《Technical code for water proof in underground engineering》
Clear stipulaties in the 4.1.7 articles of GB50108-2008 specifications：" fracture width is not greater than 0.2mm, and must not penetrate through ".Notice this
A provision regulation is safe in engineering structure, but such as without considering other waterproof measures, consequence is also to be difficult to imagine.Therefore
To inhibit and reducing the leakage of concrete, and concrete is effectively avoided or reduced by carbonate in underground water and chlorion etc.
Full bag waterproofing design is taken in corrosion, more and more underground engineering project considerations.
Traditional deep basal pit is generally constructed from bottom to top using open type Open Cut Method, with subway and underground engineering
Large scale construction, underground engineering contrary sequence method can effectively control surrounding enviroment deformation, reduction to make it to the characteristics of ground time effects
Gradually promoted in the whole nation.Contrary sequence method refers to that each layer basement of below ground using top-down sequence of construction, is gone downstairs by ground
The horizontal rigidity and compression strength of harden structure generate support action to foundation pit, ensure the earth excavation of foundation pit.
Since basement floor construction is constructed from top to down, the earthwork at this time is not yet excavated, the exterior wall and structural column of basement
Completion cannot be poured before floor construction construction, it is therefore necessary to it is the vertical temporary support pile foundation of structural column setting, and exterior wall
Supporting construction of the floor at place then directly with foundation pit both sides is connected, using supporting construction as vertical supporting.
Since inverse floor of making is connected by reinforcing bar with supporting construction, the waterproof material at this node is cut by reinforcing bar tunneling boring
It is disconnected, it can not really realize full bag waterproof.
Therefore, how effectively to solve the above problems, the full bag waterproof that underground structure is further realized in contrary sequence method is mesh
Preceding engineering circles thorny problem urgently to be resolved hurrily.

The lower end of the connecting portion is extended in the lower end of the laying scope of water coiled material, and upper end covers the lower half of the interim construction beam
Point.
When the underground structure completion of the building, after the floor external wall structure time is built, the interim construction beam is removed
Concrete parts, expose the upper end that the waterproof roll covers the interim construction beam the latter half, for being built with follow-up
It is overlapped in the process with other waterproof constructions.
Preferably, if the position that the foundation pit enclosure structure corresponds to the interim construction beam is equipped with the L-shaped reinforcing bar in arterial highway,
One end of " L " the shape reinforcing bar bending, which is buried, builds in the foundation pit enclosure structure, and the other end is horizontal to the interim construction beam direction
To the stretching foundation pit enclosure structure；" L " the shape reinforcing bar stretches out one end of the foundation pit enclosure structure and the interim construction
Bar construction connection in beam.
Preferably, it is to build that the reinforcing bar in the connecting portion, which is connected with the bar construction in the interim construction beam in an entirety,
Build the vertical reinforcement of beyond the region of objective existence wall.
Preferably, the lower end of the connecting portion is equipped with reinforcing bar connector and is cast in bar connecting inside the connecting portion.
The beneficial effects of the utility model：
1) structure stress is clear.
Pre-buried U-typed reinforcing bar in supporting construction, breaks U-typed reinforcing bar one end during construction straight L-shaped, makees with inverse at floor
Newly-increased interim construction beam connection, with contentedly downstairs harden structure bears horizontal loading, supporting construction shares floor vertical load
Requirement.
2) waterproof measure simple structure.
Waterproof roll is overlay with supporting construction joint in inverse floor of making, and reserves certain lap of splice, in order to the later stage
Return the connection for building stage waterproof roll.Waterproof material and construction, easy for construction, input cost base consistent with standard paragraphs external wall waterproof
This is without increase.
3) construction on internal structure and design are without influence.
Exterior wall vertical reinforcement is set in newly-increased interim construction beam, this reinforcing bar is retained when the later stage cuts, External Wall pours
It builds and designs without influence.
This waterproofing node has effectively expanded the construction means of underground engineering, has promoted technical progress of industry, has good warp
Ji, social benefit.The technique effect of the design of the utility model, concrete structure and generation is made below with reference to attached drawing further
Illustrate, to be fully understood from the purpose of this utility model, feature and effect.
