Embodiment Construction

[0024] In order to make the technical means, creative features, goals and functions achieved by the present invention clearer and easier to understand, the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments:

[0025] The present invention proposes a kind of upside-down profiled steel and bamboo plywood retaining soil construction method, and it is suitable for the earthy and rocky filling slopes in general areas below 20m, and the earthy excavation slopes that need vertical slope cutting, including the following steps:

[0026] 1), construction of anti-slide piles; use the polar coordinate method to position and stake out the anti-slide piles at the slope. After the first section of the anti-slide pile retaining wall is formed, use a total station and a level to put the axis and elevation on the retaining wall, and paint Make a mark, and according to the coordinate points after detection, carry out the const...

Abstract

The invention provides a reverse structural steel and bamboo splint soil retaining construction method. The reverse structural steel and bamboo splint soil retaining construction method comprises the following steps that slide-resistant piles are constructed; earthwork excavation is carried out on a first layer by 3 meters of the construction flat base; temporary supporting is carried out on slopes by connecting the slide-resistant piles in a butted manner and installing structural steel and bamboo splint soil retaining structures; the second step and the third step are circulated every 3 meters till the pile top elevation of an underground building is reached; main barricades, barricade waterproof layers and protective layers are constructed sequentially; earthwork which is 0.5 m high is backfilled and compacted; and the sixth step is circulated every 3 meters from bottom to top till all backfilling is completed. By means of the reverse structural steel and bamboo splint soil retaining construction method, the construction cost can be greatly saved, and the construction period can be remarkably shortened.

Description

technical field [0001] The invention relates to a building construction method, in particular to a soil-retaining construction method of upside-down section steel and bamboo splints. Background technique [0002] With the leapfrog development of China's urban construction, the construction of large-scale high-rise building foundations and basements, large underground shopping malls, underground parking lots, underground stations, underground transportation hubs, underground substations, etc. are faced with the problem of deep foundation pit engineering ;Due to complex and changeable engineering geology and hydrogeological conditions, higher and higher requirements for environmental protection, development of foundation pit engineering scale towards super large area and large depth, and increasingly complex development conditions such as construction schedule and resource conservation; traditional deep foundation pits The construction method can no longer meet people's needs,...
