Embodiment Construction

[0015] The present invention is a novel retaining wall supporting structure and construction method of road bank embankment protection, such as figure 1 , figure 2 , image 3 As shown, there is a buttress-type retaining wall 18 with a cross-section approximately triangular in its structure, behind which the buttress-type retaining wall 18 is the reinforced soil 4, and the prestressed anchor rod 1 passes through the wall panel 2 and is embedded in the buttress 3 Inside the reinforced soil 4 behind the wall, cement mortar 6 is poured around the anchoring section 5 of the prestressed anchor 1, and a layer of anti-corrosion material 8 is coated on the free section 7 of the prestressed anchor 1. Set the PVC plastic casing 9 on the outside, wrap the cement mortar 6 around the PVC plastic casing 9, anchor the end of the prestressed anchor rod 1 on the wall panel 2 with the anchor head 10, set expansion joints 11 and weep holes in sections 12. The earth pressure on the buttress ret...

Abstract

The invention relates to a novel barricade supporting structure for a road or river bank dam and a construction method thereof. A pre-stressed anchor (1) passes through a shingle (2) and a buttress (3) and is embedded in a reinforced soil mass (4); a cement mortar (6) is injected around an anchoring section (5) of the pre-stressed anchor (1); an end part of the pre-stressed anchor (1) is anchored on the shingle (2) by an anchor head (10); and expansion joints (11) and draining openings (12) are arranged in sections. The construction method comprises the following construction steps: constructing a base pile (13); pouring a wall base plate (14) and a reinforced concrete river bank dam (15); constructing the pre-stressed anchor (1); constructing the shingle (2) and the buttress (3) thereof; reserving the expansion joints (11) and draining openings (12) in sections; compacting wall-behind filling (16); applying a pre-stressing force by the pre-stressed anchor (1); fixedly locking the anchor head (10) fixedly connected with the pre-stressed anchor (1) by an anchoring tool (17); and constructing a next working surface according to the steps.

Description

technical field [0001] The invention relates to the supporting technology of the side slope. Background technique [0002] In the past, gravity-type (weight-weight) retaining walls were mostly used as support technologies for highway bank embankments. The method of gravity retaining wall can be made of rubble masonry or plain concrete pouring. This method mainly relies on the self-weight stiffness of the retaining wall to resist the lateral pressure of the soil behind the wall. [0003] The disadvantages of this support technology are: (1) self-heavy; (2) high rigidity and poor seismic performance; (3) poor overall stability and insufficient anti-overturning capability. Therefore, the overturning and sliding of the retaining wall often occurs, which affects the safety of engineering facilities. At this time, it is necessary to consider improving the support scheme and design a new support selection to make this type of project safer and more economical. Contents of the in...
