Technical field
The utility model relates to the technical fields of civil construction project, are unearthed in platform foundation pit more particularly, to a kind of rigidity
Support construction.
Background technique
At present in the supporting construction of foundation pit, generally the platform that is unearthed can be set in one side of foundation pit, when facilitating excavation pit
Transport to soil.
Existing foundation pit supporting construction generally comprises the support frame being fixed on foundation pit side-wall, so that in excavation pit,
To foundation pit until support effect so that foundation pit is not easy to collapse during excavation；One is built in the side of foundation pit to be unearthed
The tool for transporting soil is placed on unearthed platform by platform, worker, then will be put out of foundation pit using the soil that loop wheel machine is sling
It sets in the tool for transporting soil, soil is transported to specified place and is placed.
Prior art among the above has the following deficiencies: that when the foundation pit of excavation is deeper, loop wheel machine needs to stretch out longer
Lifting rope the soil in foundation pit can be transported on unearthed platform, meanwhile, as the width of excavation of foundation pit is increasing, be unearthed
Also with increasing, user needs to put into biggish cost and goes to build support frame and go out for what platform needed accordingly build area
Native platform needs to improve this so that project cost is higher.
Utility model content
The purpose of the utility model is to provide a kind of unearthed platform internal support of foundation pit structures of rigidity, and having reduces project cost
Effect.
The above-mentioned purpose of the utility model has the technical scheme that
Fluted, groove is excavated around the circumferential direction of foundation pit in a kind of unearthed platform internal support of foundation pit structure of rigidity, the periphery of foundation pit
The interior circumferentially fixed spud pile for having the spaced several rectangles by armored concrete production around foundation pit, adjacent two solid
Determine that protective net is installed between stake, there are spacing between spud pile and foundation pit, there is installation rigidity between spud pile and foundation pit side-wall
Fixed plate, successively along several spud piles, helically ascending manner extends toward the top surface of foundation pit fixed plate, and the spud pile leans on
The side projection of nearly fixed plate is fixed with no less than two in n shape and the fixed link of hollow setting, and fixed link is arranged in rigidity, Gu
Side on fixed board close to spud pile offers no less than two through-holes, and screw, screw and fixed link screw thread are equipped in through-hole
