Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of construction devices, in particular to a soil hole reinforcing and supporting device. BACKGROUND

[0002] The soil hole is a special geological structure formed by the overburden of soluble rock stratum under the action of potential corrosion, which requires the conditions of soil layer susceptible to potential corrosion, underground water flow channel and water level frequent fluctuation. The soil hole reinforcement is to support and reinforce the soil layer at the top of the soil hole to avoid soil collapse and burying of the soil hole. The arc-shaped supporting device supports and reinforces the soil layer to improve the stability of the soil hole.

[0003] However, when the supporting device reinforces the soil hole, the supporting plate is fitted on the soil hole, and the supporting rod is placed in the middle of the soil hole to provide vertical supporting force for the supporting plate at the top of the soil hole. The middle supporting rod easily divides the space of the soil hole into two channels, which is not conducive to the passage of personnel from the middle of the soil hole. The supporting plates are fitted on the top of the soil hole, and the connection between the supporting plates is prone to gaps. The vibration generated during the excavation of the soil hole is easy to cause the soil to fall from the gap, which is easy to cause the pressure of the soil on the supporting plate to be unbalanced, and the soil at some positions is easy to bend the supporting plate due to the large extrusion force, thereby causing the collapse of the soil hole position.
