Abstract

The invention discloses an auxiliary measuring device used for raking pile construction. The auxiliary measuring device comprises a folded plate and a portal. The length of long plate bodies of the folded plate is equal to the diameter of a raking pile hole. The length of a bevel edge of a right-angle plate of the portal is equal to that of the long axis of an oval orifice of the raking pile, and the length of a second right-angle edge is equal to the diameter of the raking pile hole, that is, the midpoint of the second right-angle edge, the midpoint of the bevel edge and the midpoints of the long plate bodies of the folded plate are on the same straight line. The distance between the midpoint of the bevel edge and openings of the folded plate is measured according to computation, the deviation between the computed value and the measured value can verify the deviation between the inclination angle of the dug depth and the ideal inclination angle, and the inclination angle of the raking pile under the condition that manually dug holes are deep is ensured through the scheme. According to the construction method, the measuring device in the scheme is adopted for measurement after the raking pile depth is greater than 2.5 m, eight sets of data are measured and sampled, comparison between the eight sets of data and the computed distance is conducted, the inclination angle of the raking pile is corrected, and the inclination angle of a raking pile under the condition that manually dug holes are deep is further ensured.

Description

technical field [0001] The invention belongs to the field of inclined pile construction in construction engineering, and in particular relates to an auxiliary measuring device for inclined pile construction and a construction method thereof. Background technique [0002] At present, in China, inclined pile pile foundations are widely used in the construction of arch bridges, and the construction technology of inclined piles is relatively mature at home and abroad. Because inclined piles are often drilled directly by rotary drilling rigs in construction, they are drilled with a well-set angle of inclination. Piling technology is relatively mature and advanced. [0003] However, under special geological conditions, it is usually designed as a manual digging construction method for inclined pile construction. At this time, how to ensure the measurement of the diameter and inclination angle of the pile hole, and the choice of construction method are particularly important. In C...
