Safety protection facility for circular manual hole digging pile construction and use method of safety protection facility

Abstract

The invention provides a safety protection facility for circular manual hole digging pile construction and a use method of the safety protection facility. The safety protection facility includes a protection plate, a frame, an upper supporting leg, a lower supporting leg, a signal detector and a signal emitter, the signal detector is mounted on the frame of the protection plate, the signal emitteris mounted on a soil holding container, and by detecting the distance between the signal emitter and the signal detector and the running speed of the signal emitter, whether the protection plate is opened to allow the soil holding container to pass through or not and when the protection plate is opened are determined. The use method includes the application steps that (1) the supporting legs areadjusted, and the protection plate is mounted; (2) the soil holding container is lowered near the protection plate, and the protection plate is opened to allow the soil holding container to pass through and is closed immediately; (3) the soil holding container is lifted near the protection plate, and the protection plate is opened to allow the soil holding container to pass through and is closed immediately; (4) falling objects and the soil holding container fall off, and the protection plate is not opened; (5) the position of the protection plate is adjusted along with increasement of the down digging depth; and (6) the protection plate is lifted out after the hole digging depth reach a design value.

Description

technical field [0001] The invention relates to the safety protection technology during the construction of manual hole-digging piles. Background technique [0002] Pile foundation is a foundation form that is widely used in civil structures at the present stage. In the pile foundation construction process, the hole forming process mainly includes mechanical hole forming and manual hole digging. Compared with mechanical hole forming, manual hole digging has its own advantages, especially for pile holes with medium pile diameters, manual hole digging piles have the advantages of low construction cost, simple mechanical equipment, and easy control of hole pile diameter. . However, manual digging requires personnel to work at the bottom of the hole, and there are often the following problems: (1) The sundries at the hole mouth fall into the hole, which will cause damage to the construction personnel at the bottom of the hole, and the deeper the hole is dug, the more serious t...

Problems solved by technology

However, manual digging requires personnel to work at the bottom of the hole, and there are often the following problems: (1) The sundries at the hole mouth fall into the hole, which will cause damage to the construction personnel at the bottom of the hole, and the deeper the hole is dug, the more serious the damage will be

(2) During the lifting process of the earth-moving equipment, the sudden decoupling of the earth-moving equipment, the disconnection of the earth-lifting cable, and the failure of the winch equipment may cause the sudden fall of the earth-moving equipment and injure the construction personnel at the bottom of the hole.

[0003] In the construction process of excavating piles at the present stage, relatively few protective measures are adopted, which mainly include the following two aspects: (1) General protective measures are mainly to prevent debris from falling at the hole opening, and for soil containers in the hole drop doesn't work

(2) Since the soil container has to enter and exit the orifice repeatedly during the soil transportation process, if protective measures are arranged at the orifice or within a certain depth in the hole, it will be troublesome to get the soil container up and down, and even affect the progress of the project

In view of this situation, anti-falling object measures are often rarely used on the site, which will leave a safety hazard for the construction site.
