Abstract

The invention relates to the technical field of pile foundation hole digging, in particular to a manual hole digging pile hole mechanical high-pressure grouting construction protection device and a manual hole digging pile hole construction method. By combing selection and installation of a to-be-dug pile foundation site of the manual hole digging pile, and by combining the arrangement of the connecting relation among stand columns, a protective shed, a winch, a soil container, a telescopic retaining wall, a protective end plate, a well bottom, a water collecting pit, a drainage pipe, a crawling ladder, an air supply pipe, the front end of a retaining wall and other components, rainwater and falling objects can be effectively prevented from falling into a manual hole digging pile hole in the construction process of the manual hole digging pile, the safety of constructors is ensured, meanwhile, the device is simple in structure and good in wall protection effect, the excavated well wallis protected through fixed connection between the front end of the protection wall and the telescopic protection wall and telescopic protection wall operation of the telescopic protection wall, the defects that in the traditional concrete pouring process, the difficulty is large, and the pouring protection period is long are overcome, and the protective security is improved.

Description

technical field

[0001] The invention relates to the technical field of pile foundation hole digging, in particular to a mechanical high-pressure grouting construction protection device for manually digging pile holes and a construction method for manually digging pile holes. Background technique

[0002] In the construction process of manual excavation of pile foundations, in order to prevent the hole wall from collapsing, it is usually necessary to pour a layer of concrete on the inner wall of the pile hole every time a certain depth is dug down. The layer is relatively loose and water seepage, the conventional retaining wall cannot be poured, even if it is poured, it is easy to cause collapse, resulting in the inability to carry out normal digging construction, and it is easy to cause safety accidents. At present, for the above-mentioned defects, the method of high-pressure grouting or planting bars is used for reinforcement. High-pressure grouting is to drill a hole from...
