Description

Structure pressurizer and block structure with structure pressurizer applied {structure pressurizer and block structure with structure pressurizer}

The present invention relates to a structure pressurizing tool for pressurizing a structure in a nailing method (rock nail, soil nail, rock bolt) or anchor method, and a block structure to which the structure pressurizing tool is applied, and more specifically, to a block structure fastened to the tip of a nail. The purpose is to provide a structural pressurizing tool used in the nailing method or anchoring method to provide functionality in which the pressing force applied to the block structure to which the tip of the nut or PC steel wire is connected can be provided evenly to the slope (rock surface). will be.

In addition, the present invention fixes the lower pressurizing member constituting the structure pressurizing port as described above to a reinforcing bar member embedded in the block structure, or attaches a pressure plate further provided below the lower pressing member constituting the structural pressurizing port to the block structure. The aim is to provide a block structure to which a structural pressurizing section is applied by being buried.

Nailling method (rock nail, soil nail, rock bolt) or anchor method fixes and integrates the rock of the surface layer, which has become soft due to excavation and blasting of the cut site, to the stable internal rock with rock bolts, preventing the falling rocks on the cut surface. It is to prevent or prevent surface separation.

Rock nails mainly refer to nails installed on slopes formed by rock layers. It is often constructed simultaneously with cross blocks, stepped retaining walls, etc.

Soil nails mainly refer to nails constructed on slopes formed by soil sections. They are often constructed simultaneously with grid blocks, cross blocks, and stepped retaining walls.

Rock bolts are a reinforcement method with a nail length of about 5m that is mainly inserted for the purpose of achieving a keying effect in the rock layer, and are often constructed together with green soil, shotcrete, and rockfall prevention nets.

When nailing is done on a slope, the joint layers of the internal rock and strata are tied together with nails, making several strata become one layer and forming a beam at both ends, increasing the shear resistance of the internal rock and stratum and load bearing. Not only is neutrality greatly improved, but internal stability and strength are also greatly improved.

When the internal strata of a slope are made up of several layers, if each stratum is not tied together, that is, each stratum is separated, and horizontal and vertical activity occurs along the bedding surface, causing a very serious problem in terms of slope stability. However, when these strata (thin layers) are bound by nailing, friction between active strata is generated and activity between strata is suppressed. The ability to inhibit stratum activity by nailing is proportional to the shear strength or tensile strength of the nails. In addition, several strata bound by nailing become one layer, creating a type of fixed beam effect.

Rock bolts are usually constructed simultaneously with green soil, rockfall prevention nets, and shotcrete. When constructed simultaneously, the rock shear resistance increases and the load-bearing capacity of the rock increases. In addition, the residual strength increases even after the rock yields. This phenomenon can be seen as an improvement in the physical properties of the entire cut surface due to the rock bolt. The acupressure plate plays the role of applying compressive force by pushing the fall prevention net or wire mesh for shotcrete toward the cut surface, and the material used is mainly a square (flat plate).

A block structure 300 such as a stepped retaining wall is placed, and an acupressure plate 2 is placed on the nail 200 exposed in front of the block structure 300, and a nut is attached to the threaded portion 210 formed at the tip of the nail 200. A configuration is provided to pressurize the acupressure plate (2) by fastening (5).

However, in the case of the above configuration, the slope of the slope 100 is different for each site, and as a result, the right angle between the nail 200 and the acupressure plate 2 does not match, so when the acupressure plate 2 is pressurized and fixed with the nut 5, the nut ( 5), there is a problem that only a portion of the acupressure plate 2 is pressed, causing a pressurization defect, and a means to solve this problem is required.
