Structure is equipped with through-hole that is big with pilot hole etc. and being connected to pilot hole at guide part axle center；The earth-retaining portion is to be fixed on guide part
The inclination plate structure in outside is held, the slanted upper end in earth-retaining portion is fixed on guide part upper end, and inclination lower end is to far from guide part one
Side extends to form down big up small pyramidal structure.
The further earth-retaining portion inclination lower end is provided with support portion；The support portion is coaxial with guide part
Vertical tubular structure, support portion lower end are supported on the bottom surface of pilot hole surrounding, and upper end is supported in earth-retaining portion inclination lower end.
The mobile position limiting structure in restricted earth-retaining portion is set between the further support portion and earth-retaining portion.
The further position limiting structure includes limiting slot；The limiting slot be fixed on earth-retaining portion tilt lower end and
Downward opening inverted U slot；The upper end of the support portion is fastened in limiting slot.
There are 30~60 ° of angles between further the earth-retaining portion and guide part end face outside.
The utility model can be improved the positioning accuracy of basic pilot hole screw pile by the way that guide part is arranged in pilot hole, pass through
Earth-retaining portion, which avoids drilling being unearthed, falls after rise to pilot hole, the auxiliary construction workload that basis pours surface dust cleaning is reduced, to improve
The construction efficiency that basic pilot hole and basis pour, has great promotional value.

Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments.
Such as Fig. 1~2, a kind of boring auxiliary mould structure, the auxiliary mould structure of the present embodiment is mainly used for providing base
The positioning accuracy of plinth pilot hole screw pile and avoiding, which drills to be unearthed, to be fallen after rise to pilot hole.1 He of guide part including being located at 5 upper end of pilot hole
It is set to the earth-retaining portion 2 in 1 outside of guide part, guide part 1 is the vertical tubular structure coaxial with pilot hole 5, and guide part is set at 1 axle center
There is through-hole 6 that is equal big with pilot hole 5 and being connected to pilot hole 5, in actual use, spiral pilot hole machine passes through through-hole 6 and enters pilot hole 5
Interior, guide part 1 can play the role of guidance guiding, improve the positioning accuracy of spiral pilot hole machine.The lower end of guide part 1 is direct
It is fixed on the bottom surface of 5 upper end surrounding of pilot hole, is smooth transition between the internal end surface of through-hole 6 and the inner wall of pilot hole 5.
Earth-retaining portion 2 is the inclination plate structure being fixed on the outside of 1 upper end of guide part, and the slanted upper end in earth-retaining portion 2 is fixed on
1 upper end of guide part, inclination lower end extend to form down big up small pyramidal structure, earth-retaining portion 2 and guiding to far from 1 side of guide part
There are 30~60 ° of angles between 1 end face outside of portion, as shown in Figure 1, in actual use, it can be by 45 ° preferably.
Drilling, which is unearthed, is directly transferred to 1 outside of guide part by inclined earth-retaining portion 2, and far from guide part 1, will not fall back to and draw again
In hole 5.
In order to improve the stability in earth-retaining portion 2 and surface dust be avoided to be collected in earth-retaining portion 2, the present embodiment inclines in earth-retaining portion 2
