Manual hole digging pile assembly type protection wall and construction technology thereof

Abstract

The invention discloses a manual hole digging pile assembly type protection wall which is composed of a prefabricated component, an auxiliary part and cast-in-place concrete. The prefabricated component comprises a well ring, a well opening and a standard joint. An inverted circular truncated cone opening is formed in the inner side of the well ring. The well ring is connected with the well opening. The well opening is formed by splicing three arc plates, and multiple sprue gates A evenly distributed are formed in the upper portion of the well opening. The standard joint is formed by splicingthree arc plates, and multiple sprue gates B are evenly formed in the upper portion of the standard joint. Connecting holes and reserved holes are reserved in the well opening and the standard joint.The auxiliary part comprises wooden wedges, vertical connecting hooks, horizontal nails and grouting floral tubes. The diameter of the protection wall is adjusted in a fine manner among the arc plates, and the well opening and the standard joint are connected through the vertical connecting hooks via the connecting holes. The cast-in-place concrete comprises a well ring cushion layer, well openingsit grout (mortar), prefabricated component (well opening and standard joint) connectors and fat groove (well opening and standard joint) packing. The manual hole digging pile assembly type protection wall is fast in construction progress, and the hole forming quality is more reliable.

Description

Technical field [0001] The invention belongs to the field of construction technology, and specifically relates to a manual digging pile assembly type wall protection and a construction technology. Background technique [0002] Manually digging piles is one of the important pile forming methods. It has the characteristics of flexible pile diameter, low cost, and high construction efficiency. It is widely used today. Manual digging pile is a pile formed by first using manual excavation method, then placing a steel cage and pouring concrete to form a pile. However, manual digging pile adopts manual excavation method, the hole wall is easy to collapse during the excavation process, and there is a great safety hazard. , And in areas with abundant groundwater, a large amount of groundwater needs to be pumped, which is easy to cause settlement of surrounding roads and pipelines. [0003] Traditional manual digging piles generally adopt upside-down cast-in-place wall protection, and the t...
