Multi-nut-seat assembled uplift pile

Abstract

The invention discloses a multi-nut-seat assembled uplift pile, which comprises pile blocks and a plurality of L-shaped anti-rotation connecting plates. A square end plate is arranged at the end of each pile block, at least two nut seat groups are sequentially disposed in each pile block along a direction of from the corresponding end plate to the middle of the pile block, a distance is reserved between each two adjacent nut seat groups, each nut seat group includes four sub-groups, each sub-group includes two nut seats, and four edges of each end plate correspond to four nut seat sub-groups respectively. Two adjacent nut seats in two adjacent sub-groups are connected with two end edges of one L-shaped anti-rotation connecting plate respectively, and the two end edges of the anti-rotation connecting plate extend along a direction of from the end plate to the middle of the corresponding pile block and are connected with the positionally corresponding nut seats in the corresponding adjacent groups. The multi-nut-seat assembled uplift pile has the advantages that the way of connecting two uplift piles is added, destruction of the connection of the two uplift piles by underground water can be avoided, tensile strength and bending resistance of the two end plates can be improved, and accordingly the properties of the integral pile are improved.

Description

technical field [0001] The invention relates to an uplift pile, in particular to a multi-nut seat assembled anti-lift pile. Background technique [0002] In the foundation pile construction, the phenomenon of pile connection will occur due to various factors. In most cases, the weldability of the metal end plate of the pile body is used to weld the two end plates with electric welding after the pile body is aligned. In general, there is no problem, but due to various phenomena of geological conditions, the buoyancy of groundwater in some areas is large and the destructiveness of groundwater to the welding surface is strong. This connection method by electric welding cannot meet the architectural design requirements. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a multi-nut seat assembled uplift pile that can improve the tensile strength and bending stre...
