Embodiment 1

[0111] Example 1: Yibin Lingang Economic Development Zone Binjiang Avenue Phase I Section I

[0112] The project is located in Lingang Economic Development Zone, Yibin City, Sichuan Province, at the middle section of Binjiang Avenue in Lingang Economic Development Zone. The north side of the road is close to the mountain, and the total slope support along the line is 50,000 square meters, and the slope height is up to more than 40 meters. Among them, the frame slope protection is about 17,000 square meters.

[0113] In order to control the construction cost of frame slope protection and speed up the construction progress, the applicant adopted the construction method of frame slope protection of this application in the construction of road excavation frame slope protection, and achieved success, effectively controlling the quality and safety of slope support engineering construction , cost and duration.

Embodiment 2

[0114] Example 2: "Four Roads" construction project in the northern new town of Shunqing District

[0115] The project is located in Nanchong City, Sichuan Province, including four roads: Binhe Road, Tongjiang Avenue, Dayingshan 1st Road, and Dayingshan 2nd Road. The total investment of the project construction is 288 million yuan, of which the total area of ​​the road excavation slope is 40,000 square meters (the frame slope protection is about 8,600 square meters), and the highest slope is as high as 25 meters. The project started on August 7, 2014 and is still under construction.

[0116] Generally speaking, the construction method of wet-mix shotcrete for frame slope protection is adopted in the construction of frame slope protection, which has brought extremely significant economic and social benefits in terms of construction cost, construction period, construction quality and safety .

Abstract

The invention discloses a construction method of a frame revetment, belongs to the technical field of slope stabilization, and aims to solve the problems that in the prior art, construction cost is high, the construction period is long, and potential safety hazards are prominent. The construction method mainly comprises the steps of slope excavation, erecting of a scaffold, cleaning of a working surface, construction of an anchor rod, construction of a frame beam, concrete pouring, maintenance, and the like. The frame revetment manufactured through the construction method has the advantages that construction cost is low, the construction period is short, safety is high, and construction quality is high.

Description

technical field [0001] The present invention relates to the technical field of frame slope construction, in particular, it is a construction method for spraying frame slope protection with wet-mixed concrete. One-time pouring area greater than 600m 2 , Excavated slope frame slope protection support with slope slope ≤ 1:1. Background technique [0002] With the rapid development of China's economy, traffic problems within cities and between cities have become increasingly prominent. Over the years, the government has vigorously carried out the construction of urban roads and expressways, aiming at improving the efficiency of traffic travel. Geographically, Chongqing is surrounded by Daba Mountains, Wushan Mountains, Wuling Mountains and Dalou Mountains in the north, east and south respectively, and its landforms are dominated by hills and mountains. Therefore, road subgrades in traffic construction are doomed to be filled or excavated, and there are many slopes, making cons...
