Description
Technical field
This utility model relates to prefabrication and assembly construction construction technology, deep foundation pit supporting structure, outer wall of basement structure and construction new technical field, the novel two wall unification construction technologies that a kind of applicable urban architecture City Regions, particularly construction space are narrow and small.
Background technology
Along with Chinese Urbanization level improves, city " parking difficulty " problem is on the rise, and supporting requirement of people's air defense is improved, and building structure constantly develops toward underground, and multi-storey basement is the most common.In recent years the development strategy requirement of pipe gallery is set up in the city that country proposes.Deep-foundation pit engineering comes into a New Times, but the design and construction of the supporting construction to deep basal pit, mostly adopt traditional way, using stake to add inner support, such method for protecting support is only temporary structure, when foundation ditch completes, its service life terminates, not only cost is higher, and produces substantial amounts of building waste, slurry waste fluid in work progress, stays under ground portion and following urban construction is stayed hidden danger.In view of economy, using diaphram wall to obtain substantial amounts of use as " two wall unifications " construction technology of building structure exterior wall, economy is obvious, also reduces environmental effect simultaneously.
Current " two wall unifications " construction technology, use the axis that trench machine requires along design, under the conditions of mud off, excavate out a long and narrow deep trouth, after clear groove, in groove, hang steel reinforcement cage, then a unit groove section is built up with tremie method underwater concreting with tremie method, so carry out piecemeal, build up one continuous print armored concrete wall in underground, as intercepting water, antiseepage, load-bearing, water-retaining structure.
But, existing construction of diaphragm wall machinery takes up room relatively big, and matching operation plant equipment is more.This technology is generally used for space, place sufficient openr big, deep basal pit.Narrow for excavation area place, surrounding enviroment require that high and that construction space is limited foundation ditch is difficult to use this construction technology.Additionally, substantial amounts of slurry waste fluid is produced in work progress, easy breakthrough at ground wall framing construction joint, relatively greatly and body of wall does not solidifies and is easily separated between front concrete and rebar to meet groundwater run off, cast-in-place ground-connecting-wall metope is rougher, even there will be folder mud phenomenon, need to do one water-resistant liner wall, the carrying of prefabricated ground-connecting-wall and hang cumbersome, the connection between section and section is not easy to process.
Utility model content
This utility model aims to overcome that drawbacks described above, there is provided a kind of speed of application fast, environmental protection, can mass production, on-site consolidation, construction technology is simple, and construction space demand is little, and construction noise is little, form body of wall self-strength high, body of wall waterproof, seepage control is good, easy to connect with beam, plate, can also serve as two walls unification underground connection wall structures of basement building structure exterior wall as deep footing groove enclosing structure.It is applicable to the local underground structure built intensive in urban population, that field construction space is little, periphery engineering-environment control deformation requirements is strict.Urban architecture compact district pattern foundation pit supporting structure difficulty problem, transformation district, old city " parking difficulty " problem, old building " basement increasing layer " construction technology difficulty problem can be solved.
In order to realize above-mentioned technical purpose, the technical scheme that this utility model employing is the most concrete:
A kind of underground connection wall structure, including big small wing I-steel, beard reinforcing bar and fill concrete, wherein, by connecting snap close connection between the long wing plate side of multiple described big small wing I-steel, corner configuration corner pieces forms the exterior wall of continuous steel construction, connects steel diaphragm and form the inner wall of continuous steel construction between the short limb plate side of big small wing I-steel；Fill concrete and beard reinforcing bar between exterior wall and inner wall, described beard reinforcing bar is for by concrete and wall connecting.
As the improvement of a kind of underground of this utility model connection wall structure, being additionally provided with some steel diaphragms between exterior wall and inner wall, some described steel diaphragms will be divided into some compartments between exterior wall and inner wall.
As the improvement of a kind of underground of this utility model connection wall structure, the connection side of the long wing plate of each two big small wing I-steel is bent into pin thread and box respectively, and described pin thread and box are interconnected to form described connection snap close.
Novel underground diaphragm wall structure of the present utility model, has the advantage that compared with traditional continuous underground wall structure
Steel structure member can customize with factory, site operation, economy, and speed of application is fast, reliable in quality, environmental protection.As foundation pit enclosure structure, it is not necessary to maintenance, internal engagement bracing members system substantially increases foundation pit construction speed.Steel construction sealing is reliable, reliable construction quality；As basement structure outer wall, intensity is high, can flexible arrangement reinforcing bar, structural beams, structural slab according to demand.After becoming wall, self barrier performance is good, it is not necessary to waterproof roll liner, economical reliable.Space limits little, can be according to place level, vertical direction spatial flexible arrangement, connection.It addition, can be in conjunction with sink well technique, reversed construction etc..

Detailed description of the invention
Below in conjunction with the accompanying drawings and the technical solution of the utility model is described in detail by specific embodiment:
Embodiment 1
As shown in Figure 1, a kind of underground connection wall structure, including big small wing I-steel 1, beard reinforcing bar 4 and fill concrete, wherein, connected by connection snap close 5 between the long wing plate side of multiple described big small wing I-steel 1, corner configuration corner pieces 2 forms the exterior wall of continuous steel construction, connects steel diaphragm and form the inner wall of continuous steel construction between the short limb plate side of big small wing I-steel 1；Fill concrete and beard reinforcing bar 4 between exterior wall and inner wall, described beard reinforcing bar 4 is for by concrete and wall connecting.
As the improvement of a kind of underground of this utility model connection wall structure, being additionally provided with some steel diaphragms 3 between exterior wall and inner wall, some described steel diaphragms 3 will be divided into some compartments between exterior wall and inner wall.
As the improvement of a kind of underground of this utility model connection wall structure, the connection side of the long wing plate of each two big small wing I-steel 1 is bent into pin thread and box respectively, and described pin thread and box are interconnected to form described connection snap close 5.
The construction method of a kind of continuous underground wall structure, comprises the following steps:
The first step: be designed calculating according to site condition and storehouse, ground planning arrangement, propose big small wing I-steel 1, corner pieces 2, the parameter request of configuration beard reinforcing bar 4；
