Description
Technical field
The present invention relates to Architectural Equipment field more particularly to it is a kind of for slope excavate shallow foundation hole slope protecting device and
Means of defence.
Background technique
Engineering slope protection, as important a part in base pit engineering, tool has very important significance, have slope protection and
Retaining structure protects two classes.The common measure of slope protection has the plastering such as mortar or tabia, whitewashing, pneumatically placed concrete, grouts piece
Stone revetment, shotcrete slope protection, anchor and spray net slope protection etc..Such measures mainly to protect excavation slope slope surface the soil body occur sliding and
Phenomena such as collapsing.If fine, slight slope is in drying regime, and native intensity is high, and the stability of slight slope is all right.If in rainy season,
Especially Continuous heavy rain, a large amount of rain infiltration make the strength reduction of soil, may cause slight slope sliding.Therefore it is applied in shallow foundation hole
For work process generally by the way of slope excavation, slope surface hangs steel fabric sheet pneumatically placed concrete.This measure prevents side slope from outward appearance to inner essence
By weathering Erosion and Rainfall simulator erosion, the stabilization of side slope is effectively guaranteed in shallow foundation hole.But part shallow foundation cheats engineering soil
Matter is preferable, and soil stabilization, water level is lower, and due to the Soil Slope Stability of itself, without hanging, steel fabric sheet pneumatically placed concrete is such
Strict side slope protection scheme is more wasted if if hanging by the way of steel fabric sheet pneumatically placed concrete.
Therefore, technical field of buildings is badly in need of a kind of preferable, soil stabilization, the lower shallow design of foundation pit of water level for soil property
Slope protecting device and means of defence reach the protection purpose of side slope to reduce cost.
