[0090] Embodiment 1, a kind of solidification method of dredging mud quilt, its scheme and steps are as follows:

[0091] (1) Mixing ratio: silt 100, water 200, alkali slag 10, curing agent 15.9.

[0092] (2) Implementation steps: material entry - detection - sludge, alkali slag, and curing agent are stirred in sequence - dredging mud quilt - vacuum water absorption - maintenance - test.

[0093] (3) Indicators: 28-day compressive strength of 2.88 MPa, cohesion of 65 kPa, and internal friction angle of 22 degrees.

Embodiment 2

[0094] Embodiment 2, a kind of technical example of novel iron tailings concrete manufacture, its scheme and steps are as follows:

[0095] (1) Mixing ratio: sludge 100: water 10: alkali slag 5.6: curing agent 10.6.

[0096] (2) Implementation steps: material entry - detection - iron tailings, alkali slag, curing agent stirring in turn - transportation, filling mud quilt - drainage - maintenance - testing.

[0097] (3) Indicators: 28-day compressive strength of 1.12 MPa, cohesion of 45 kPa, internal friction angle of 18.5 degrees.

Embodiment 3

[0098] Embodiment 3, a kind of technical example of novel iron tailings concrete manufacture, its scheme and steps are as follows:

[0099] (1) Mixing ratio: sludge 100: water 150: alkali slag 4.5: curing agent 7.5, dredging mud is used as sea reclamation material.

[0100] (2) Implementation steps: material entry - detection - stirring machinery in place - alkali slag, curing agent stirring slurry - stirring, wet spraying - maintenance - testing.

Abstract

The invention provides a solidification method for a hydraulic reclamation silt quilt. The method includes the steps of determining the mixing proportion, wherein raw materials are grasped, and mixingproportion testing is carried out indoors to determine the preset mixing proportion; mixing the raw materials, wherein the preset mixing proportion is input into a control device, a stirring device automatically controls the input quantity of the raw materials, the raw materials are stirred through a stirring mechanism, and the viscosity of the mixture in the stirring mechanism is monitored in real time so that an MCU processor can calculate the uniformity of the mixture; carrying out hydraulic reclamation of the silt quilt, wherein the mixture reaching the preset uniformity is conveyed intoa hydraulic reclamation device, the hydraulic reclamation device automatically detects the mass of the mixture and automatically reclaims the mixture to a construction site when the mass of the mixture exceeds the preset mass, and surplus moisture is removed with a preset method to form the silt quilt. The solidification method for the hydraulic reclamation silt quilt effectively solves the problems that an existing solidification method for a hydraulic reclamation silt quilt is high in operation difficulty and high in construction cost and wastes time and labor in the construction process.

Description

technical field [0001] The invention relates to the technical fields of municipal engineering and marine engineering, in particular to a method for solidifying dredge fill mud. Background technique [0002] At present, the traditional dredger-filled sand quilt embankment technology is to blow-fill medium-fine sand into the sand quilt bag, and use it as embankment body material after drainage. This process requires a large amount of sand and gravel resources. With the strengthening of environmental protection, natural resources are becoming increasingly tense, the supply of sand and gravel materials is in short supply, and the price is soaring. [0003] Traditional sludge solidification mostly uses cement as the cementitious material. Cement production requires a lot of energy and causes certain environmental pollution. Limestone resources for cement production are increasingly scarce. In addition, the effect of cement solidifying sludge is poor and the cost is high, so t...
