Embodiment 1

[0036] Such as figure 1 As shown, the method for strengthening the revetment foundation of the soft stratum slope comprises the following steps:

[0037] Step 1, clean up the soft ground layer:

[0038] Step 1.1, using static pressure to press the conical probe into the soil at a constant rate and at a constant speed, the sensor in the conical probe is input to the recorder in the form of electrical signals and recorded, and then converted into pressure through the calibration coefficient, and the change with depth is obtained. Pressure curve, and then divide the soil layer in the construction area according to the curve, and determine the depth and range of the soft soil layer;

[0039] Step 1.2: Excavate drainage ditches and water collection wells along the edge of the soft ground; the drainage ditch is 50cm wide and 60cm deep; the length, width and height of the water collection wells are 2m×2m×1.5m;

[0040] Step 1.3, laying steel plates on the track of the excavator, and ...

Embodiment 2

[0052] On the basis of Example 1, when aiming at the thicker slope foundation reinforcement treatment of silt, on the basis of Example 1, such as image 3 As shown, the method for strengthening the revetment foundation of the soft stratum slope comprises the following steps:

[0053] Step 1, clean up the soft ground layer:

[0054] Step 1.1, using static pressure to press the conical probe into the soil at a constant rate and at a constant speed, the sensor in the conical probe is input to the recorder in the form of electrical signals and recorded, and then converted into pressure through the calibration coefficient, and the change with depth is obtained. Pressure curve, and then divide the soil layer in the construction area according to the curve, and determine the depth and scope of the soft soil layer;

[0055] Step 1.2: Excavate drainage ditches and water collection wells along the edge of the soft ground; the width of the drainage ditch is 50cm, and the depth is 80cm; ...

Abstract

The invention discloses a reinforcement treatment method of a bank revetment foundation on a soft formation slope, and belongs to the technical field of soft foundation treatment. The reinforcement treatment method comprises the specific steps: soft soil layer clearing, powder clay layer backfilling, pine pile arranging, concrete pouring and settlement state detecting. A soft ground layer is cleared, powder clay is backfilled and rolled, thus the settlement time is shortened, and the risk of uneven settlement is lowered; because of pine pile reinforcement, the foundation compaction effect is improved, and the foundation bearing capacity is improved; the bearing capacity of the slope foundation is improved through pond slag backfilling, friction force between a base and a replacement filling clay layer is increased, sliding damage of the riverway slope foundation is prevented, a construction process is simple, the site adaptability is high, and occupation of a construction site is small; and no other noise exists during construction, and incidents such as resident disturbing are avoided.

Description

technical field [0001] The invention belongs to the technical field of soft foundation treatment, and in particular relates to a reinforcement treatment method for bank revetment foundations of soft ground slopes. Background technique [0002] Soft ground foundation refers to the foundation composed of soft soil layer. Soft soil generally refers to the cohesive soil in soft plastic to fluid plastic state with high natural water content, high compressibility, low bearing capacity and low shear strength. In engineering, soft soil is often subdivided into soft sticky soil, muddy soil, silt, peaty soil and peat. It has high natural water content, large natural void ratio, high compressibility, low shear strength, small consolidation coefficient, long consolidation time, high sensitivity, large disturbance, poor water permeability, complex layered distribution of soil layers, and The physical and mechanical properties are quite different among them. Because of its engineering ...
