Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and in particular to a protective casing used on rocky riverbeds with shallow soil cover at large angles. Background Technology

[0002] Casings are used in bored pile construction. They are made of steel and are cylindrical. During the process of manually excavating bored piles, due to unstable soil conditions, it is difficult to construct reinforced concrete retaining walls. Therefore, steel retaining walls are used to protect the bored pile, prevent the hole from collapsing, and avoid affecting the construction progress and safety. The steel casing is a circular barrel with two hollow ends, made of sheet metal according to the size of the bored pile. Its main functions are to stabilize the hole wall, prevent the hole from collapsing, isolate surface water, guide the drill bit, fix the pile position, and protect the original working ground.

[0003] A search revealed a Chinese patent (authorization announcement number CN201843077U) disclosing a casing used on a rocky riverbed with a shallow, steeply sloping soil cover. This casing is composed of several connected sections, with the bottom section having an inclined elliptical cross-section. The bottom steel plate of the bottom section has a bevel. This patented technology uses high-hardness Q345 steel for the bottom section and a 30° bevel on the bottom steel plate to facilitate insertion into the rock, preventing damage when subjected to extreme impact stress. Furthermore, the inclined elliptical cross-section of the bottom section ensures a closer fit to the riverbed surface, completely solving the problem of concrete leakage during bored pile grouting.

[0004] However, the above-mentioned devices still have some drawbacks in actual use. The most obvious one is that the casing currently used on rocky riverbeds with shallow soil cover at large angles is a round barrel made of sheet metal with empty ends. It does not have any tensile strength. When the casing is used on rocky riverbeds, the rapid water flow may cause the casing to tilt, making the casing not securely installed. Utility Model Content
