Abstract
The utility model relates to a support structure in building construction, in particular to a foundation pit support air bag suitable for a deep and narrow foundation pit and aiming to provide the foundation pit support air bag with the advantages of high installation speed, low construction cost and recyclability. The foundation pit support air bag disclosed by the utility model is composed of a outer sheath (1) and an inner container (2), and the inner container (2) is provided with a connector (3) and a safety valve (4) and is arranged inside the outer sheath (1); and a plurality of the foundation pit support air bags can be mutually connected through the connectors (3) to form an air bag assembly for common use. According to the utility model, specific to the construction characteristics of the deep and narrow foundation pit, the air bags are used for supporting the deep and narrow foundation pit, and the support can be completed simply and rapidly by the steps of selecting the air bags of corresponding number and size according to the characteristics of different foundation pit, sequentially connecting the air bags, placing the air bags in the foundation pit and the carrying out inflation operation; and the foundation pit support air bag has the beneficial effects of novel design, reasonable structure, simplicity in operation, convenience in use, rapidness, safety and high-efficiency in construction, and capabilities of saving labor force and material resources and largely reducing the construction cost.
Description
Technical field
The utility model relates to the supporting and protection structure in the building operations, is specially a kind of pattern foundation pit supporting structure air bag that is adapted to dark narrow foundation ditch.
Background technology
In the engineering field, pattern foundation pit supporting structure is in order to guarantee the safety of underground structure construction and foundation ditch surrounding enviroment, and retaining, reinforcing and safeguard measure that foundation pit side-wall and surrounding enviroment are adopted.Usually the pattern foundation pit supporting structure that adopts on the engineering is that the mode of anchor pole, baffle plate, stull, perpendicular support even diaphragm wall is carried out supporting to foundation ditch, and the type of pattern foundation pit supporting structure is put slope excavation, deep layer stirring concrete earth enclosure wall, high-pressure rotary jet grouting pile, channel-section steel steel sheet pile and bored pile usually.Though but it is big to put slope excavation low price engineering backfill amount, remaining other types construction cost is high, and it is extremely low to be applied in the temporary lining cost performance; These pattern foundation pit supporting structure types cost when realizing the temporary lining of foundation ditch is very high, and the manual work of use is also a lot, and the device behind the construction operation all can not Reduplicatedly utilize; Cost is bigger; Particularly narrow for the foundation ditch width, foundation ditch more deeply and the temporary lining of the foundation ditch that caves in easily again, construction cost is high; Efficiency of construction is low, implements very difficulty.
Summary of the invention
The purpose of the utility model is to provide a kind of installation rate fast, and construction cost is low, the pattern foundation pit supporting structure air bag that can recycle.
A kind of pattern foundation pit supporting structure air bag of the utility model is made up of overcoat 1 and inner bag 2, it is characterized in that, inner bag 2 places overcoat 1 inside and is provided with connector 3 and safety valve 4; Connector 3 passes overcoat 1 with safety valve 4 and is provided with; Several pattern foundation pit supporting structure air bags can interconnect through connector 3 successively forms fit common use of group of balloons.
Further, described overcoat 1 is processed by rubber or nylon or plastics.
Further, described inner bag 2 is processed by rubber, and two ends respectively are provided with several connectors 3 up and down.
Further, be provided with in the described connector 3 can be independent sealed the air intake-exhaust mouth.
Further, described overcoat 1 and inner bag 2, after inflation, swell with exterior portions at connector 3 at two ends up and down, and bump height is not less than connector 3 height.
A kind of pattern foundation pit supporting structure air bag of the utility model to the construction characteristic of dark narrow foundation ditch, adopts air bag that it is carried out supporting; Only need select the air bag of respective numbers and size according to the characteristics of different foundation ditches; Connect successively, put into the hole, inflate operation then and just can accomplish supporting simply fast; Its beneficial effect is, modern design is rational in infrastructure, and is simple to operate, easy to use, and it is fast and safely efficient to construct, and uses manpower and material resources sparingly, and greatly reduces construction cost.

The specific embodiment
Instance 1
A kind of pattern foundation pit supporting structure air bag of the utility model; As shown in Figure 1, it comprises overcoat 1 and the inner bag 2 that is arranged in the overcoat 1, and inner bag 2 connector 3 and safety valve 4 that are provided with; Overcoat 1 and inner bag 2 are processed by rubber, and inner bag 2 is respectively equipped with two connectors 3 up and down.When carrying out the pattern foundation pit supporting structure operation, as shown in Figure 2, in Rock soil Foundation 6, dug ground foundation ditch 5; The degree of depth according to ground foundation ditch 5 is fit through the group of balloons that connector 3 is linked into appropriate length by a plurality of air bags; Be communicated with and sealing through connector 3 between the air bag, put it into then in the good foundation ditch of excavation, connector 3 inflations of air bag from the top at last; The connector 3 of air bag bottom keeps sealing bottom; Can directly push the hole wall of ground foundation ditch 5 after the whole inflations of air bag, prevent that the ground foundation ditch 5 that excavates from caving in, and the connector 3 of connection air bag inflated the back mutual extrusion together with exterior portions; The destruction of not only having protected connector 3 not receive the native stone that drops, and a guarantee that can rely on also is provided for follow-up construction; After foundation ditch carries out engineering construction, open the connector 3 of air bag topmost, the gas in the air bag is emitted, and the air bag of extracting out in the foundation ditch supplies next unit ground foundation ditch 5 to use.
A kind of pattern foundation pit supporting structure air bag of the utility model, its overcoat 1 are processed by nylon, and inner bag 2 is processed by rubber, and all the other compositions are identical with method for using, can be applicable to the supporting of interim foundation ditch.
