Description
Technical field
The utility model is related to that a kind of cutting depth is deeper, the higher short section borehole wall of the cycle operation frequency, armored concrete
The inverse of plate makees short section pouring structure, belongs to underground structrue engineering field.
Background technology
With economic growth and the acceleration of urbanization process, available aboveground space is fewer and fewer in city, city hair
The contradiction of exhibition and land resource shortage is more protruded.The existing use insufficient space of existing building, it is necessary to reasonable development, using both
There is the underground space of building.It is general to be constructed using cut and cover method in underground engineering construction.Although cut and cover method has construction letter
The advantages such as list, cheap, the work progress degree of controllability height of engineering direct cost, but there is also notable deficiency at present：One is cut and cover method
Construction is higher to the protection cost of existing facility, and the construction period is relatively long.Cause engineering indirect cost and auxiliary duration significantly
Increase；Two be that cut and cover tunneling is very big to the normal influence on system operation in city.Traffic route, drainage pipeline networks in the range of Effects on Engineering,
The existing facility such as water power coal gas, is unavoidably interfered；Three be that cut and cover tunneling influences very big to city appearance environment.Whole construction
Process is in the environment of opposing open, and the influence to city appearance environment is very big.In view of this, opening for exploitation Deep underground space is explored
Dig new technology new method imperative.
The excavation of foundation pit of current widely used underground engineering is mostly, along the practice, successively to excavate, successively support, and is led to
Often applicable excavation of foundation pit is shallower, for excavating compared with deep basal pit, and this method has that construction period is longer, and engineering reliability is not strong,
The shortcomings of technique substantially falls behind.Reverse construction is that underground space development cost is most economical, the most reliable method of technology, due to inverse
Some tiny technical problems of practice construction there are not solution, cause the advantage of reverse construction unobvious, therefore, for contrary sequence method
Construction is the problem of exist, and supporting construction when how to provide a kind of low underground space reverse construction of safe efficient, cost is
The technical problem of those skilled in the art's urgent need to resolve.
Utility model content
It is simple the utility model proposes a kind of constructing operation, efficiency of construction and construction speed are improved, economic technology benefit shows
The inverse of work makees short section pouring structure, solves the problem of prior art is present.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：
A kind of reverse construction short section borehole wall pouring structure, including the structure the initial segment, the first structure that are sequentially connected are maintained
Section, the second structure keeping section and the 3rd structure keeping section, the structure the initial segment include the vertical body of the initial segment and the initial segment level
Structure, the horizontal structure body is placed on supplemental rigid slope retaining body, and the 3rd structure keeping section is fixed with bed die to be connected
Connect.
The supplemental rigid slope retaining body is pilework.
The structure the initial segment, first structure keeping section, the connection of the second structure keeping section and the 3rd structure keeping section structure
Position is in step-like, and coupling part is provided with dowel.The dowel is in " E " type.The dowel of " E " type improves structure starting
Section, first structure keeping section, the bonding strength and rigidity of the second structure keeping section and the 3rd structure keeping section connecting portion, " E "
The dowel of type is arranged at the structure the initial segment, first structure keeping section, the second structure keeping section and the 3rd structure keeping section
Bar construction in, can connect up and down two-part reinforcing bar, become an entirety.
The characteristics of the utility model has following and beneficial effect：
One kind that the utility model is related to is inverse to make short section pouring structure, by setting the structure the initial segment being sequentially connected, the
One structure keeping section, the second structure keeping section and the 3rd structure keeping section, the side of the structure the initial segment supporting construction keeping section
Pressure, structure keeping section maintains the lateral pressure for the next segment structure keeping section of rear support that expires, and the structure the initial segment completes mixed
After solidifying soil pours and conserves and expire, start pouring structure keeping section, pour and prepare for next segment structure keeping section after having poured.
Structure keeping section lateral pressure relies primarily on the preceding paragraph structure and is supported, when starting to pour next segment structure, structure keeping section
As permanent structure, circulation construction on the premise of structure safety is ensured, improves efficiency of construction, improves 100% construction speed.
