Safeguard device on manhole pile head and setting method thereof

Abstract

The invention relates to a manhole pipe pile head safety device, which includes a connection interface preset at the pile head, and a protection enclosure, wherein, the bottom of the protection enclosure is equipped with an insertion section adapted to the connection interface, and partial lateral surface of the protection enclosure is provided with imports and exports for ingress and egress of personnel and earth materials. By setting the connection interface at the manhole pipe pile head, the bottom of the alone manufactured protection enclosure is equipped with an insertion section adaptedto the connection interface, which allows the connection between the protection enclosure and the pile head to be dismountable, thereby the safety device can be repeatedly used; at this time, the pile head part higher than the structure bedding course operations surface is no longer constructed, thereby the production of concrete rubbish, scrap steel material and the like will be reduced, which saves material and protects environment. In addition, a mounting method of the manhole pipe pile head safety device is provided.

Description

Manhole pile head safety device and setting method of the device technical field The invention relates to a safety device in construction engineering, more specifically, to a reusable manhole pile head safety device and a setting method for the manhole pile head safety device. Background technique In order to ensure the safety of the construction in the manhole pile, etc., the manhole pile must comply with relevant safety regulations. As shown in Figure 1, the manhole pile head 11 in the prior art is usually about 20cm higher than the normal pile construction operation surface 12, and the pile head is constructed with reinforced concrete, which is not only used as the pile head protection wall, but also as the pile head The safety device utilizes the steel bar about 1 meter higher than the pile head as the skeleton 13, and hangs the safety net 14 on the skeleton, thereby forming the safety device 10 of the single pile, which has been used for many years. In the prior art...

Problems solved by technology

In the prior art, when the pile cap formwork construction is carried out after the pile internal construction is completed, it is necessary to excavate the excessive part of the pile head (including the safety device part of the pile head and the wall part of the empty pile) and the excess earthwork, resulting in construction waste, Moreover, the skeleton in the safety device needs to be dismantled and cannot be reused, which wastes a lot of steel bars
