Embodiment Construction
[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, on the premise of no conflict, the embodiments or technical features described below can be combined arbitrarily to form new embodiments. .
[0026] It should be noted that when a component is referred to as being "fixed to" another component, it can be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intervening component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a co-existing centered component. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for illustrative purposes only.

The invention discloses a bridge pile foundation construction extruding and supporting disc hole forming method. A percussion drill, a rotary excavating drill and a rotary drill are matched to machine a main hole to form a hole; after the main hole is formed, a hole detector is adopted to detect whether the hole depth, the hole diameter and the perpendicularity deviate or not, the corresponding model of a branch disc machine is selected according to the pile diameter of a pile foundation, extrusion and expansion operation is conducted, in the construction process, extrusion and expansion pressure is detected to generate actual detection data, and all branch disc extrusion and expansion operation is conducted in sequence; and after extrusion and expansion are completed, hole cleaning treatment is conducted, a reinforcement cage is put down, and concrete pouring is conducted. A percussion drill, a rotary drilling drill and a rotary drilling drill are matched to process a main hole and form a hole, a detection step is matched with an extrusion and expansion operation step, and continuous operation is carried out by sequential extrusion and expansion, hole cleaning and subsequent steps, so that the problems that a geological rock stratum is hard and a common hole forming process is difficult to construct are solved, the hole forming speed of a pile foundation is increased, and the pile length required by the pile foundation is shortened; the construction period is guaranteed, and economic benefits are remarkable.
Description
technical field [0001] The invention relates to the field of bridge pile foundation construction, in particular to a method for forming a hole for a squeezed support plate in bridge pile foundation construction. Background technique [0002] At present, in the construction of bridge pile foundations, some areas have complex geology, many interlayers, and hard rock layers, some of which are as high as 180 MPa. The general bridge pile foundations in the prior art mostly use conventional drilling methods such as impact drilling, rotary drilling or rotary drilling. In the case of "complex geology, many interlayers, and hard rock formations", conventional pore-forming processes are difficult to meet the schedule requirements in such geology, the equipment pore-forming loss is large, the pore-forming time is long, and the resource waste is serious. SUMMARY OF THE INVENTION [0003] In order to overcome the deficiencies of the prior art, one of the objectives of the present inven...
