Description

A kind of batter post group anchor formula rock foundation
Technical field
The utility model relates to high voltage power transmission technical field, be specifically related to a kind of have certain on overburden layer mountain area rock geology condition under the novel batter post group anchor formula rock foundation that is suitable for.
Background technology
Mountain area ultra-high-tension power transmission line institute overburden layer thickness on earth's surface, region often reaches 1m ~ 5m, being then severely-weathered or middle weathered rocks below.If this type of geological conditions adopts heavy excavation basis, easily cause engineering evolution amount large, the consequences such as environmental destruction is serious.
Utility model content
Problem to be solved in the utility model is to provide a kind of novel batter post group anchor formula rock foundation, on 1m-5m overburden layer mountain route engineering in, both basement rock supporting capacity can have been given full play to high, be out of shape little feature, avoid again heavy excavation to cause engineering quantity to increase and environmental destruction, to realize the engineering effort of environmental protection and economy as far as possible.
The technological means that the problem solving utility model adopts is:
A kind of batter post group anchor formula rock foundation, comprise batter post slab foundation and group's anchor formula rock foundation, described batter post slab foundation comprises sole plate 2, tiltedly column 1 and inserted angle steel 4, and described oblique column 1 tilts to be fixed on sole plate 2, and described inserted angle steel 4 inserts in oblique column 1; Described group's anchor formula rock foundation is made up of at least one rock bolt 3, described sole plate 2 is distributed with rock bolt 3, described rock bolt 3 inside is provided with dowel 10, the top of dowel 10 is provided with anchoring crotch 8, and dowel 10 is passed sole plate 2 and is anchored on sole plate 10 by anchoring crotch 8.
Described oblique column 1 comprises and is installed on oblique main bar upright column 5 in oblique column 1 and stirrup 6,
The main body section material that described rock bolt 3 surrounds dowel 10 is mortar or pea gravel concreten.
Described sole plate 2 have base plate top reinforcement 7 and base plate lower floor reinforcing bar 9.
The gradient of described oblique column 1 is consistent with the gradient of tower leg main material.
Described inserted angle steel 4 replaces with stone bolt.
Described anchoring crotch 8 parallel short muscle or anchor slab replace.
The beneficial effects of the utility model: the oblique column gradient of the present utility model is consistent with the tower leg main material gradient, and steel tower upper load can pass to sole plate center, it is compared with traditional straight column type basis, and the moment of flexure that upper load produces at base plate is very little.Upper pull out operating mode under, inclined column foundation and Rock Bolt Foundation can collaborative works, fraction uplift force is heavily offset by necromancer on base plate, major part uplift force is born by group's anchor formula rock foundation, the moment of flexure produced at base plate due to upper load is very little, and each anchor pole on average can bear uplift load, means that they can collaborative work, reach capacity bearing capacity simultaneously, thus significantly improve the breakout capacity of Rock Bolt Foundation.

Detailed description of the invention
Below by the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the utility model provides a kind of batter post group anchor formula rock foundation, comprise oblique column 1, sole plate 2, inserted angle steel 3, inserted angle steel 3 is inserted in oblique column 1, inserted angle steel 3 is fixed on sole plate 2, around inserted angle steel 3, concreting forms oblique column 1, also has oblique main bar upright column 5 and stirrup 6 in oblique column, and the upper and lower of sole plate 2 is distributed with base plate top reinforcement 7 and base plate lower floor reinforcing bar 9 respectively; Described group's anchor formula rock foundation is made up of at least one anchor pole 3, and anchor pole 3 to be built around dowel 10 by mortar or pea gravel concreten and formed, and dowel 10 is anchored in sole plate 2 by anchoring crotch 8.Establish anchoring crotch 8 on the top of dowel 10, effectively can connect sole plate 2 and rock bolt 3, also can effectively reduce the thickness of sole plate 2.
In certain embodiments, inserted angle steel 4 also can replace with stone bolt, and anchoring crotch 8 can replace with parallel short muscle or anchor slab.In certain embodiments, the radical selecting anchor pole 3 is 8, is distributed in the rectangular edges around inserted angle steel 3.
The gradient of oblique column 1 is consistent with the gradient of tower leg main material, and this structure can make the load on steel tower top can pass to the center of sole plate 2, and compared with traditional straight column type basis, the moment of flexure that upper load produces at base plate is very little.Upper pull out operating mode under, inclined column foundation and Rock Bolt Foundation can collaborative works, fraction uplift force is heavily offset by necromancer on base plate, major part uplift force is born by group's anchor formula rock foundation, the moment of flexure produced at base plate due to portion's load is very little, and each anchor pole on average can bear uplift load, therefore means that they can collaborative work, reach capacity bearing capacity simultaneously, significantly improves the breakout capacity of Rock Bolt Foundation.
The sole plate 2 on top and the Computing Principle of oblique column 1 adopt the heavy method of soil, and bottom then adopts the Computing Principle of rock bolt.Batter post slab foundation and group's anchor formula rock foundation resist the active force that top steel tower transmits jointly, wherein uplift force is born jointly by heavy and between rock bolt 3 and rock the cohesion of soil of pulling out the soil body on above sole plate 2, significantly can reduce baseplate width compared with slab foundation, reduce evolution amount; Downforce is born by the rock face under sole plate.
First by bottom group's anchor formula rock foundation construction molding during the utility model construction, then build top batter post slab foundation.Idiographic flow is as follows:
1) upper overburden layer is excavated to bedrock surface;
2) in basement rock, implant dowel 10 after machine drilling and build mortar or pea gravel concreten in boring;
3) after group's anchor foundation rock bolt 3 is shaping, in foundation ditch, put into the reinforcing bar of slab foundation and inserted angle steel or stone bolt, and carry out the location of inserted angle steel or stone bolt, guarantee that its gradient is consistent with the tower leg main material gradient;
4) concrete of batter post slab foundation is built.
