Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] The anti-collapse protection device in the pit of the present invention relates to the early stage of construction, the process of pit exploration construction (digging a smaller deep pit to find out the underground layout and pipeline method) or local deep pits (such as excavation of elevator shafts and foundations of deep pit caps) Among them, it is a protective device for personnel to prevent collapse during the construction of the pit bottom. It has the advantages of wide range of use, convenient assembly, safety and firmness, and reusability, etc., and can effectively solve the safety hazards of engineering excavation of small-area deep pits.
[0023] First, see figure 1 As shown, the anti-collapse protection device in the pit of the present invention mainly consists of a first pit wall guard plate 11, a second pit wall g...

The invention discloses an underground collapse-prevention and protection device, which comprises a first pit wall protection plate, a second pit wall protection plate and horizontal telescopic rod groups supported between the first pit wall protection plate and the second pit wall protection plate. The first ends of the horizontal telescopic rod groups are vertically arranged on the first pit wall protection plate in a sliding way; first lock bolt pieces locked with the first pit wall protection plate after sliding in place are arranged on the first ends of the horizontal telescopic rod groups; the second ends of the horizontal telescopic rod groups are vertically arranged on the second pit wall protection plate in a sliding way; and second lock bolt pieces locked with the second pit wall protection plate after sliding in place are arranged on the second ends of the horizontal telescopic rod groups. According to the underground collapse-prevention and protection device provided by the invention, the first pit wall protection plate, the second pit wall protection plate and the horizontal telescopic rod groups supported between the first pit wall protection plate and the second pit wall protection plate are adopted to combine into a relatively sealed protection space, so that a safe and stable underground construction environment is provided for construction personnel.
Description
technical field [0001] The invention relates to the field of building construction, in particular to an anti-collapse protection device in a pit. Background technique [0002] For a long time, both government departments and construction companies have very strict requirements on safety production in construction. In the early stage of construction of various projects, especially in the earthwork stage, it is often necessary to use exploration pits to find out the underground conditions, or to excavate deeper structural parts such as elevator shafts and cap foundations according to design requirements, and it is necessary to excavate a smaller Deep pits often reach a depth of more than 2m. When working in the pit, personnel face a greater risk of earth collapse and the upper objects falling. General traditional protective measures are difficult to meet the requirements in terms of safety, practicability and economy. Contents of the invention [0003] The technical proble...
