Embodiment
Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning
Same or similar element or element with same or like function are represented to same or similar label eventually.Below by ginseng
The embodiment for examining accompanying drawing description is exemplary, is only used for explaining the utility model, and can not be construed to of the present utility model
Limitation.
It in the construction of Practical Project, can meet in shoal area, such as flood period, basis will be soaked and rushed
Brush, the problem of causing larger on support stability influence；Equally construction area coating is thin residing for, when inclination of strata degree is big,
Selection to bracket basis form is also particularly significant.In view of the presence of above mentioned problem, with reference to Fig. 1, the utility model provide with
Lower foundation structure, to improve the security of construction, it includes：
Rock stratum deep hole 1, steel reinforcement cage 2, steel pipe 3, concrete 4；
Wherein, the rock stratum deep hole 1 is in cylinder, and it is drilled through by drilling machine；The diameter of the rock stratum deep hole is to drill
The size of machine setting is defined, after the cleaning to all dregs in bottom hole and hole is completed, the diameter of rock stratum deep hole may have it is trickle partially
Difference, but the specific implementation of the foundation structure provided the present embodiment does not cause obstruction.
Wherein, the steel reinforcement cage 2 includes the first cage body 21 and the second cage body 22；The cage body of first cage body 21 and second
22 are made up of the tie hoop 202 of cage bar 201 and spiral surrounding main ribs, and main ribs 201 vertically lay by interval；It is described
The cage bottom 221 of the bottom of second cage body 22 is in inversed taper platform shape, and it is easy to the alignment with rock stratum deep hole 1 when steel reinforcement cage 2 is overall to transfer, and
Improving efficiency of construction reduces the friction of steel reinforcement cage 2 and rock stratum deep hole 1, reduces coming off for soil sand between hole, more conducively improves stake
The steadiness on basis.Wherein, first cage body 21 is in outside rock stratum deep hole 1, and second cage body 22 is embedded in rock stratum deep hole 1
It is interior.Further, the height of the second cage body 22 is less than the height of rock stratum deep hole 1, i.e., transferred when by steel reinforcement cage 2 to rock stratum deep hole 1
When, the bottom of the steel reinforcement cage 2 is not contacted with the bottom hole of the rock stratum deep hole 1, leaves certain spacing.
