Background
River regulation generally refers to the regulation of river channels, and belongs to hydraulic engineering. The engineering riverway revetment adopts the revetment form of a retaining wall at multiple places along the bank, and comprises an inclined retaining wall, a constant weight retaining wall, a gravity retaining wall and a retaining wall type retaining wall. In order to meet the aims of building green ecological riverways and beautifying the riverways, ecological brick veneers are designed on the front surfaces of the retaining walls; the fixing mode of the ecological brick adopts galvanized steel bars as the original design for bar planting
The distance between the embedded bars along the height direction of the wall is 600mm, the distance between the embedded bars along the river direction is 1500mm, the length of the embedded bars extending into the concrete anchor is more than or equal to 260mm, the length of the exposed hooks is about 50mm, and the design uplift resistance is more than or equal to 10kN. The steel bar planting construction process comprises drilling → hole cleaning → glue injection → steel bar insertion → maintenance, the drilling depth is deep, special tool equipment is needed for hole cleaning, labor and time are wasted, steel bar planting construction belongs to fine operation, skilled technical workers are needed, the steel bar planting construction can be put into use after being maintained for 24 hours, the field supervision difficulty is high, and the construction progress requirement cannot be met.
The front surfaces of the standard section retaining walls (strength grade C30) are slightly inclined backwards, the ecological bricks are normally leaned against the retaining walls and belong to self-stabilizing structures, and the condition of accident prevention is solved by adopting a bar planting method for fixation. The main withdrawal resistance that the bar planting provided to guarantee that ecological brick does not leave the wall, and expansion bolts can also provide the withdrawal resistance, as long as the withdrawal resistance that it provided is not less than the design withdrawal resistance (being more than or equal to 10 kN) of bar planting. Looking up the JB/ZQ4763-2006 Standard of expansion bolts,
the stainless steel expansion bolt has the total length L =110mm and the drilling depth of 75mm, can provide the pullout resistance of 10.3kN and the shearing resistance of 7.4kN, and can completely meet the construction requirements. The problems often encountered during use of expansion bolts are: due to the fact thatThe friction force between the expansion pipe and the inner wall of the hole is insufficient due to the fact that the diameter of the inner wall of the prefabricated hole is larger than the outer diameter of the expansion pipe caused by factors such as loose matrix of a wall or a building; although the expansion tube and the screw rod can be connected with each other, the expansion tube can rotate in the hole, so that the expansion tube and the screw rod rotate along with the rotation of the wrench and the nut in the nut fastening process, the nut cannot be screwed, and the expansion bolt cannot expand; however, because the inner wall of the hole is circular, the generated friction force of the hole wall is limited, when the nut locking resistance is slightly large, the situation that the nut and the screw rotate together still occurs, so that the expansion bolt cannot expand, and the working efficiency is influenced.
