Through the knowledge collation of the architectural knowledge column of this website, the basic overview of slope protection project of Zhong Da Consulting is summarized as follows:
Revetment engineering refers to the protective engineering facilities to prevent bank collapse caused by lateral erosion and local erosion of rivers, and make the main stream deviate from the erosion area. Protective measures usually include: ① directly reinforcing the bank slope and planting trees and grass on the bank slope; (2) riprap or masonry slope protection.
Through combing the relevant contents, Zhong Da Consulting Bianxiao Company takes the dam slope protection project as an example, and the main construction technology of the slope protection project is as follows:
1 Embankment toe excavation adopts mechanical excavation and manual arrangement. Foundation trench excavation should be carried out at a certain failure rate to prevent collapse from affecting the foundation size, and each side of the foundation size should be greater than the design width of 30cm, so as to facilitate support and construction.
2 After precise lofting, the formwork shall be erected according to the requirements of design drawings, and pouring shall be started after passing the supervision inspection. Laying mortar before pouring. When pouring, the amount of riprap shall be strictly controlled and shall not exceed 30% of the design. Spread mortar.
3 Before pouring concrete at the foot of the embankment, check the bracket, formwork and partition board first, and then pour it after it meets the requirements. Debris, water and dirt on the partition board in the template should be cleaned up.
(1) When pouring, it shall be poured continuously to avoid construction joints.
(2) When pouring concrete, internal vibrator and surface vibrator are used for vibration.
4 The dimensions and physical properties of dry masonry materials for slope protection should meet the specification requirements, and the surface gloss should be as uniform as possible. The stones should be fresh, free of weathered skin or cracks, and the surface should be free of impurities such as dirt and scale. Stone staggered laying, dense, neat, no prominent phenomenon, strength meets the design requirements.
Embankment slope should be trimmed manually. First, put the template on the slope and hang up the hanging line. According to the design requirements, sort out the slope types. After molding, rubble with appropriate thickness should be selected for masonry protection, and the masonry protection should be carried out in strict accordance with the hanging line. Dry masonry should be as dense as possible to prevent large cracks.
