Embodiment 1

[0052] The present application discloses a high slope construction method. Refer figure 1 with figure 2 The construction method includes the following steps.

[0053] S1, divide the high-side slope from bottom to top, the slope foot, the first stage slope, the second slope of the first stage and the lowermost slope, the lower end of the slope of each stage Platform 1 is provided;

[0054] S2, according to the total height of the proposed highside slope, the slope height and slope ratio at each stage, and the width of the platform 1;

[0055]S3, layered the slope filling, and the slope of each stage is completed after the filling of each layer is completed, and the filling is strong. After the filling is strong, the next layer of filling is continued. Practice;

[0056] S4, strongly renamed filling is in situ test, review determine the height and slope ratio of the levels at all levels, and the width of the platform;

[0057] S5, repeat step S3, thereby completing the hard work of ...

Embodiment 2

[0080] Refer image 3 Unlike Example 1, the slope protective structure in step S6 is set to an anchor, which can be enhanced as needed.

Abstract

The invention relates to an earth filling high slope construction method, and relates to the technical field of geotechnical engineering filling side slopes. The method comprises the following steps of S1, sequentially dividing a high slope from bottom to top into a slope toe at the bottom, a first-stage slope, a second-stage slope,..., an nth-stage slope and a last-stage slope; S2, preliminarily determining the height and the slope rate of each stage of slope and the width of platforms according to the total height of a proposed high slope; S3, performing layered filling on slope filled earth, and performing dynamic compaction on the filled earth after the filled earth of each layer of the slope is filled; S4, performing in-situ testing on the filled earth obtained after dynamic compaction, and rechecking to determine the height and the slope rate of each stage of slope and the width of the platforms; S5, repeating the step S3, and therefore finishing filling and tamping work of the slopes of all stages; and S6, performing excavation slope flattening on the slopes of all stages, and protecting the slope surfaces of the slopes of all stages after slope flattening is completed. The construction method has the effects of reducing the construction cost of the existing earth filling high slope and improving the construction efficiency.

Description

Technical field [0001] The present application relates to the field of geotechnical filling slope technology, in particular, relating to a construction method for high slope of filling. Background technique [0002] The filling structure is loose, high compression, and physical mechanical properties are uneven, and the stability is poor. If the necessary treatment measures are not taken after the accumulation, it is easy to produce geological disasters, so the slope of the filling is often required. The support structure such as pile plate and pile anchor is treated with compaction or consolidation method. The filling slope is difficult to obtain effective compression because the filling body is difficult to obtain, the shear strength is not high, and the height of the filling slope is often limited. At present, it is possible to improve the restricted height of the filling slope by mitigating the slope of the slope slope, and the soil in the soil reinforcement in the soil and in...
