Description
Technical field
The utility model relates to a kind of anchor pole Gravity Retaining Wall of the high slope rockmass for mountain area mountain terrain, be mainly suitable for the high slope rockmass structure that rock side slope is closed in mountain area, belong to substation project construction technique field.
Background technology
Due to alpine terrain restriction, the flat process in field of many substation projects often needs " cut into a mountain and fill out paddy ", produces high slope rockmass problem thus.This type of high slope problem often has three significantly individual features: one, place regional area forms the free face that the discrepancy in elevation is greater than 10m; Two, rock is extremely closed in domatic behind; Three, bottom free face, reserved reinforcing space is less.
The high slope rockmass method being suitable for this type of at present has Gravity Retaining Wall, anchored bolt retaining wall and reinforced earth bulkhead etc.Gravity Retaining Wall section is often comparatively large, and the reinforcing space that bottom needs increases along with the increase of height, and exist for and ensure cross dimensions and the phenomenon of again digging rock, to reinforcing, the side slope being highly greater than 10m is very uneconomical.Anchored bolt retaining wall is applicable to reinforce this type of high slope, but reinforcement material adopts steel concrete, and opposing reinforcement expense is large, and resistance to overturning is poor.Reinforced earth bulkhead filler is gathered materials on the spot comparatively convenient, but reinforcement material geo-grid needs to lay certain length, often needs to dig rock step behind, runs into hard rock, construct very inconvenient.
Shown by theory calculate and field actual measurement results: owing to closing on rock behind, the soil pressure that barricade is subject to is relatively little; But the discrepancy in elevation is large, and therefore the stability of barricade self seems very important.Under these circumstances, how to suit measures to local conditions proposing a kind of economical rationality according to actual conditions, reinforcing that eco-friendly novel reinforced method is suitable for time class side slope seems particularly crucial.
Summary of the invention
The purpose of this utility model is the deficiency overcoming above-mentioned existence, there is provided a kind of anchor pole that utilizes as the important connection of rock and barricade and Force transmission parts, to solve the anchor pole Gravity Retaining Wall for high slope rockmass producing high slope rockmass problem due to space constraint.
The purpose of this utility model has been come by following technical solution, a kind of anchor pole Gravity Retaining Wall for high slope rockmass, described high slope comprises the rock face forming mountain terrain, described anchor pole Gravity Retaining Wall comprises the stone built retaining wall of an adjacent rock face, the lateral surface of this stone built retaining wall is shaped with the steel concrete strip of one deck with steel concrete rib post; Described steel concrete strip is connected with oblique in enter in rock face through stone built retaining wall, straight cutting many connect anchor poles.
Steel concrete rib post by being connected in described steel concrete strip be embedded in stone built retaining wall with stone built retaining wall compact siro spinning technology, and described steel concrete strip is that hybrid junction has round steel rib in concrete strip; And be that hybrid junction has the reinforcement bar thicker than round steel rib in concrete rib post at described steel concrete rib post.
Fill up wall in space between described stone built retaining wall and rock face to carry on the back and banket; Described steel concrete strip is connected with uniform many oblique in banket through stone built retaining wall, the wall back of the body and straight cutting enters the steel anchor rod be fastened in rock face and by mortar injection in rock face, and described steel anchor rod is connected with reinforcement bar prefabricated in steel concrete strip.
Described steel concrete strip and steel concrete rib post arrange according to the height of barricade and length, steel concrete strip and stone built retaining wall with wide, the cross section of steel concrete rib post be long X wide=600mmX300mm.
The utility model compared with prior art, it combines Gravity Retaining Wall and anchored bolt retaining wall advantage separately, and Appropriate application barricade rock behind, part soil pressure suffered by barricade is delivered to rock interior, rational in infrastructure, clearly stressed, easy construction, is applicable to the supporting of mountain area high slope.
