Embodiment Construction

[0020] Such as figure 1 , figure 2 and image 3 As shown, the ecological anchor 5 of the present invention is a hollow porous anchor, which has a hollow tube body 1 with permeable holes 2 distributed on the hollow tube body 1, and the hollow tube body 1 is filled with a water-absorbing material 3 . The water-absorbing material 3 is sawdust.

[0021] In practical application, the hollow pipe body 1 adopts an ordinary steel water pipe with an outer diameter of 20 mm and an inner diameter of 16 mm. The surface of the ecological anchor 5 has three rows of water permeable holes 2 that are staggered and evenly distributed, with a diameter of 4 mm and a spacing of 20 mm.

[0022] The anchoring methods are:

[0023] Drill holes on the slope 4, the depth of which is 30cm, and then drive in ecological anchors 5 and ordinary anchors 6, using ecological anchors with a length of 40cm, so that the anchor head is exposed 10cm, parallel to the vegetation concrete surface, Then fill the h...

Abstract

A slope protection ecologic hollow multihole ground anchor and anchoring method belongs to the side slope protection technical field. The ground anchor comprises a hollow tube body, water permeable holes are distributed on the hollow tube body, and the hollow tube body is filled with water absorbent material. When in anchoring a method that ecologic ground anchor and common ground anchor are arranged alternately is adopted. In the invention, water permeable holes are arranged on the basis of a common steel water pipe, and dry saw powder is filled in the pipe, so that the ground anchor has mechanic anchoring performance while moisture in deep slope body is led to shadow slope body by utilizing dual actions of permeation of the water permeable holes and capillary water absorption of the saw powder, thus supplying moisture to the base material while reducing water content in deep slope body and reducing slope failure. Communication action of the ground anchor can promote 'ground gas' exchange between slope surface and the interior of the slope body, and nutrient elements contained in the 'ground gas' can further improve nutrient level of the base material. The invention is the perfection of the vegetation concrete ecological protection technology and has important application value.

Description

technical field [0001] The invention belongs to the field of ecological restoration engineering and greening engineering, and relates to a hollow porous anchor for vegetation concrete ecological protection applied to the ecological restoration of exposed high and steep slopes and an anchoring method using the anchor. Background technique [0002] Vegetation concrete ecological protection technology is mainly used for ecological restoration of exposed high and steep slopes. It has been widely used in practice and achieved good ecological benefits. However, it has been found in engineering practice that because only fissure water exists in the rock mass, the water permeability is not strong, or the penetration of water to the slope surface is blocked after the soil slope is sprayed and mixed, resulting in the rocky or soil slope being prone to The phenomenon of moisture accumulation in deep slopes and drought in shallow slopes appears. Vegetation concrete ecological protectio...
