Description

Split assembly type centering support for anchor rod and anchor rod

Technical Field

The utility model relates to a components of a whole that can function independently assembled centering support and stock for stock.

Background

The bolting technology is an efficient and economic bolting technology, is widely applied to engineering construction such as civil engineering, water conservancy, mining industry, traffic, urban infrastructure, geological disaster prevention and the like, and plays an extremely important role. Taking a traditional tension anchor rod as an example, the anchor rod consists of a free section and an anchoring section, wherein the anchoring section further transmits load to an interface between grouting body and soil body by means of the bonding action of the anchor rod rib body and the grouting body, so that the uplift bearing capacity of the anchor rod is ensured. But in the work progress, current stock adopts the smooth steel bar welding centering support of diameter 6mm (the reinforcing bar body of rod uses mostly) or adopts the plastics chuck to carry out the centering (the steel strand wires body of rod uses mostly) for the stock exists with potential risk in the work progress: (1) the weight of the rod body is supported by the steel bars by the smooth steel bar welding centering support, when the water content of a soil layer reaches a certain degree or non-dry operation drilling is adopted, the steel bar support is easy to sink into a soil body on a hole wall, centering of the rod body is difficult to guarantee, even the rod body is attached to the hole wall, the rod body cannot be fully bonded with a grouting body, the bearing capacity is greatly reduced, and a large amount of steel bar cutting, bending and welding workload is required for welding the steel bar support; (2) the thickness of the plastic chuck support is only 3-5mm, the strength and the hardness are very limited, and the plastic chuck support is very easy to bend and deform under the self-weight action of the rod body, so that the rod body is close to or even close to a hole wall soil body. Above-mentioned construction phenomenon can make the stock body of rod seriously deviate the drilling central point and put, pastes even on the drilling pore wall, leads to the stock body of rod and the adhesion force of the grout body to show and reduces, very easily appears the stock body of rod and is pulled out the destruction phenomenon.

For a tension-compression composite anchor rod (as disclosed in patent No. ZL 201420450678.5) with a remarkable bearing capacity advantage, because a fixed pressure-bearing steel plate (the diameter of the steel plate is smaller than the diameter of a drilled hole of the anchor rod) is designed on an anchor rod body, if the anchor rod body cannot be centered in the construction process, the pressure-bearing steel plate cannot be centered in the drilled hole, and a plurality of construction problems are caused. For example, because of the misalignment of the stock body of rod, the pressure-bearing steel sheet can sink to the pore wall at the bottom of the hole, the stock body of rod is putting the drilling in-process down, can lead to the pressure-bearing steel sheet to cut the pore wall soil body, produce a large amount of soil sediment and pile up in the pressure-bearing plate both sides, later stage slip casting in-process is difficult to effectively clear away clean with the soil sediment around the pressure-bearing plate, when directly leading to the stock to bear the load, pressure-bearing anchor section (be located before the pressure-bearing plate) slip casting body is because of pressing from both sides soil and presss from both sides mud and the grip of the stock body of rod and reduces, and then lead to the unable satisfied designing requirement of stock bearing capacity, bring serious potential safety hazard for the engineering.

Therefore, seek the centering support that can effectively ensure the stock body of rod is placed in the middle and the construction is convenient, extremely important to the efficiency of construction and the engineering safety of stock.
