Abstract

The invention discloses a spiral cylindrical foundation which structurally comprises a cylinder 2 and spiral blades 3. The spiral blades 3 are arranged on the inner wall and the outer wall of the cylinder 2, and the bottom of the cylinder 2 is opened. The spiral cylindrical foundation has the beneficial effects that only rock and soil in an annular area are cut in the descending process of the spiral cylindrical foundation, so that the excavation area is smaller, the construction period can be shortened, and the labor intensity is relieved.

Description

Spiral cylindrical foundation
Technical field
The present invention relates to a kind of spiral cylindrical foundation, belong to civil engineering foundation construction technical field.
Background technology
Existing foundation construction, adopts overall excavation construction mode, and long construction period, labor intensity are big, work circumstances safe degree is poor.
The hydraulic pressure that existing cylindrical foundation principle is the negative pressure by inner chamber and top is pressed into the soil body it, is only applicable to Soft Soil under water, can not be suitable for when there being boulder.
Summary of the invention
What the present invention proposed is a kind of spiral cylindrical foundation, and it is directed to the defect overcoming prior art to exist.Spiral cylindrical foundation can be made only to cut the ground in annular region in decline process, reduce excavation area, shorten construction period, reduce labor intensity.
The technical solution of the present invention: spiral cylindrical foundation, including cylinder 2 and helical blade 3;Wherein helical blade 3 is arranged on the inside and outside wall of cylinder 2, and cylinder 2 bottom opening.
Advantages of the present invention: only cut the ground in annular region in spiral cylindrical foundation decline process, so the area of excavation is less, construction period can be shortened, reduce labor intensity.

Detailed description of the invention
Spiral cylindrical foundation, its structure includes cylinder 2 and helical blade 3;Wherein helical blade 3 is arranged on the inside and outside wall of cylinder 2, and cylinder 2 bottom opening.
Described helical blade 3 is many dental structures.
Described helical blade 3 is interrupted and/or part interruption is arranged on cylinder 2.
The bottom of described spiral cylindrical foundation 1 is provided with some cutters 4 of annular space distribution.
Described cutter 4 is autogenous grinding structure.
Described spiral cylindrical foundation 1 is provided with some nozzles 5.
Technical scheme is further described below in conjunction with accompanying drawing:
As Figure 1-Figure 4, prefabricated spiral cylindrical foundation 1.It is made up of cylinder 2, helical blade 3, cutter 4 and nozzle 5 etc..Cylinder 2 bottom opening, inside and outside wall is provided with helical blade 3, and helical blade 3 can be many dental structures and can be interrupted or partly be interrupted layout;Being provided with cutter 4 bottom spiral cylindrical foundation 1, cutter 4 is the bottom that autogenous grinding structure annular is arranged in spiral cylindrical foundation 1.
As it is shown in figure 5, spiral cylindrical foundation 1 is holded up in setting position;
As shown in Figure 6, being rotated by spiral cylindrical foundation 1 under dynamic action, the ground in the annular region that bottom cutter 4 is corresponding bottom cutting tool 4 in rotary course, unnecessary ground is exported by helical blade 3;Also cutter 4 is can be without directly by the ground cutting in annular region corresponding bottom helical blade 3 bottom helical blade 3, as Figure 9-Figure 11 under Soft Soil environment;Nozzle 5 spray in decline process has the fluid reducing resistance.
After spiral cylindrical foundation 1 drops to set depth, nozzle 5 perfusion has the fluid increasing bearing capacity.Then carry out binding operation as shown in Figure 7, or excavates the ground in cylinder 2 pouring reinforcement concrete as shown in Figure 8.
Structure as shown in figures 12-16 is may be used without bottom spiral cylindrical foundation 1.
As shown in figure 14, being autogenous grinding structure cutter bottom helical blade 3, cylinder body bottom is without cutter.
As shown in figure 15, being autogenous grinding structure cutter bottom helical blade 3, cylinder body bottom is tooth form knife.
