Pile body toughening and monitoring device based on assembly ribs

Abstract

The invention belongs to the technical field of civil engineering, and relates to an assembly rib-based pile body toughening and displacement monitoring test device, which comprises an outer protective cylinder for fixing an assembly rib, a wedge-shaped assembly rib and a connecting rod for ensuring the perpendicularity of the assembly rib on the wedge-shaped assembly rib, the pressure sensors are arranged on the contact surfaces of the assembling ribs and the pile body; the stay wire displacement meters are arranged on the connecting rods; and an intelligent data acquisition device. The assembling ribs are selected, on one hand, the pulling resistance of the pile can be enhanced, meanwhile, the contact area between the pile side and soil is increased, and the pile side friction resistance is improved; meanwhile, the pile side assembling ribs can play a hoop role, the compression resistance and the horizontal displacement resistance of the pile body are enhanced, and the overall toughness of the pile body is improved; transportation is convenient, and certain engineering significance is achieved; and meanwhile, on-site installation can prevent the rib from being damaged or the sensor from being disturbed during pile pressing. And a scientific and feasible design method is provided for pile body sidesway monitoring.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a pile body toughening and monitoring device based on assembly ribs. Background technique [0002] Pile is widely used in engineering, and in various forms, it is widely used in various projects. In recent years, in order to make full use of the mechanical properties of materials, piles with special-shaped sections that can increase the side surface area or cross-sectional width of piles have been more and more widely used in practical engineering. For special-shaped piles that change the cross-sectional form of the pile, the external structure may be damaged due to the sinking method of the pile body. At the same time, the layout of the pile sensor is also affected by the pile-forming method and the pile-forming method, so the layout is not easy and has certain difficulties. [0003] Therefore, how to eliminate hidden dangers caused by failure to detect pile damage i...

Problems solved by technology

[0004] The purpose of the patent of this invention is to provide a pile body toughening and monitoring device based on assembly ribs. At the same time, the assembly rib increases the contact area between the pile side and the soil, thereby increasing the side friction resistance of the pile, increasing the overall rigidity of the pile body, and improving the bearing capacity and toughening effect of the pile body; the assembly rib is vertically connected by the connecting rod On the one hand, the connection ensures the verticality, and also plays the role of external support; the gasket acts as a hoop through the tightening of the pile body, which improves the compressive performance of the pile body; at the same time, the tensile displacement meter located on the connecting rod can monitor the pile body into the soil Depth; the displacement sensor located on the washer and the pile body can monitor the lateral movement of the pile body; the pressure sensor located on the assembly rib can monitor the surrounding soil pressure; at the same time, the survival rate of the rib can be improved in the form of an assembly rib, and at the same time, it solves the difficulty of sensor layout The problem
