Abstract
The utility model relates to wind power generation stepped bonding modified Rock Bolt Foundation, comprises that the crab-bolt cage in reinforcement foundation concrete, embedding and concrete, the some uniform Rock anchor assemblies of bed course, basic benzene plate, hoop of base concrete below form.In described rock bolt assembly, anchor pole is from bottom to top successively through lower anchoring nut, lower anchor plate, helical spring, tapered cup nut, heat-shrink tube, anchor pole benzene plate, bed course, reinforcement foundation concrete, upper anchor plate and upper anchoring nut, and every rock bolt assembly is anchored in the armature boring of rock mass by anchor pole grouting.In the utility model, rock bolt assembly top cover heat-shrink tube is isolated itself and reinforcement foundation concrete and anchor pole grouting, so that after foundation construction completes, anchor pole is applied to prestressing force.Anchor pole is screw thread or rib tooth form without the section of heat-shrink tube parcel, and a tapered cup nut is set at a certain distance, can strengthen the anchored force of rock bolt assembly, also can avoid the normal bond damage occurring between anchor pole and anchor pole grouting.
Description
Technical field
The utility model belongs to generation power foundation of wind power technical field of structures, is specifically related to a kind of bonding modified Rock Bolt Foundation.
Background technology
The wind power generation stepped prestressing force crab-bolt of rock foundation basis, if adopt conventional spread footing, foundation excavation amount is large, excavation difficulty is large, long construction period; If adopt conventional Rock Bolt Foundation,, easily there is bond-anchorage and lost efficacy in bond-anchorage limited length between anchor pole and grouting, once anchor pole bond-anchorage lost efficacy, anchor pole occurs lax, greatly reduces foundation structure safety, even causes major accident.
Utility model content
The purpose of this utility model is to provide a kind of bonding modified Rock Bolt Foundation.
The bonding modified Rock Bolt Foundation the utility model proposes, by reinforcement foundation concrete 1, crab-bolt cage 2, bed course 3, basic benzene plate 4 and Rock anchor assembly 16, formed, reinforcement foundation concrete 1 is positioned at rock mass 17 tops, and described reinforcement foundation concrete 1 is provided with bed course 3 with rock mass 17 junctions; Several crab-bolt cages 2 are embedded in reinforcement foundation concrete 1 central area ringwise, and crab-bolt cage 2 bottoms are connected with bed course 3, and bed course 3 belows, central area are provided with basic benzene plate 4, and described basic benzene plate 4 is positioned at the bottom that crab-bolt cage 2 is set; In rock mass 17, be provided with armature boring 10, some groups of rock bolt assembly 16 hoops are distributed in basis, described every rock bolt assembly 16 comprises anchor pole 5, anchor pole 5 one end are from top to bottom through reinforcement foundation concrete 1, bed course 3, be inserted in the armature boring 10 of rock mass 17, anchor pole 5 upper ends and reinforcement foundation concrete 1 are fixing by upper anchor plate 7 and upper anchoring nut 6, anchor pole 5 top covers have heat-shrink tube 8, anchor pole 5 lower ends are provided with helical spring 12, described helical spring 12 tops are fixing by tapered cup nut 11, and bottom is fixing by lower anchor plate 13 and lower anchoring nut 14.
In the utility model, the anchor pole 5 of every rock bolt assembly 16 is in the milk and 15 is anchored in the armature boring 10 of rock mass 17 by anchor pole.
In the utility model, anchor pole 5 top covers have heat-shrink tube 8, and itself and reinforcement foundation concrete 1 and anchor pole grouting 15 are isolated, so that after foundation construction completes, anchor pole 5 are applied to prestressing force.
In the utility model, basic benzene plate 4 is positioned at the below, central area of reinforcement foundation concrete 1 and bed course 3 junctions, and the setting of basic benzene plate 4 makes the prestressing force of anchor pole 5 be dispensed to more anchor rod anchored rock mass 17.
In the utility model, between anchor pole grouting 15 and bed course 3, anchor pole benzene plate 9 is set, makes the prestressing force of anchor pole 5 be delivered to anchor pole grouting 15 and rock mass 17 cross sections, make reinforcement foundation concrete 1 compress rock mass 17 simultaneously.
In the utility model, anchor pole 5 bottoms are screw thread or rib tooth form without heat-shrink tube 8 parcel sections, and a tapered cup nut 11 is set at a certain distance, bottom arranges lower anchor plate 13 and lower anchoring nut 14, simultaneously at anchor pole 5 arranged outside helical springs 12, these measures can strengthen the anchored force of rock bolt assembly 16, also can avoid the normal bond damage occurring between anchor pole 5 and anchor pole grouting 15.
The utility model advantage is:
1. rock bolt prestressing force is on the anchoring of reinforcement foundation concrete and rock mass, the rock mass cooperative bearing of basis and its below, and overturning or slip resistance analysis bearing capacity improves, and basic diameter, buried depth reduce greatly, and excavated volume reduces.
2. anchor rod anchored end is screw thread or rib tooth form, and some tapered cup nuts and helical spring are set, and has avoided light circle anchor pole and the anchor pole common bond damage that is in the milk, and has also strengthened the anchored force of anchor pole and rock mass.
3. reinforcement foundation concrete and below, bed course central area arrange basic benzene plate, make the prestressing force of anchor pole be dispensed to more anchor rod anchored rock mass scope, can improve the anchored force of rock mass to anchor pole.
