Diking method through filling sludge and curing agent into mold bags

Abstract

The invention relates to a diking method through filling sludge and a curing agent into mold bags. The method includes the following steps: step one, laying a layer of permeable filling mold bags provided with filling openings on a target mud flat surface; step two, pumping curing agent grout and sludge simultaneously into the filling mold bags from the filling openings through a curing agent pipeline and a slurry pipeline until the mold bags are full; step three, leaving the filling mold bags to stand until the sludge in the bags is solidified; step four, laying a next layer of filling mold bags on the layer, and repeating the step two and the step three; and step five, laying each following layer of mold bags sequentially according to step four and enabling the sludge in the bags to be solidified until a designed height is reached. According to the method, a technical scheme of separate slurry production and mixing filling is adopted, processes of mixing and stirring the sludge and the curing agent in advance are omitted skillfully, the curing agent grout can be prepared at an emptying point directly, materials and stirring equipment are not needed to be delivered to a construction site, and construction efficiency improvement and cost reduction are facilitated.

Description

technical field [0001] The invention relates to an embankment method, in particular to an embankment method of filling mold bags with silt mixed with curing agent, and belongs to the technical field of embankment. Background technique [0002] With the continuous development of tidal flat land resources in my country, tidal flat reclamation has developed from a simple development and utilization method of "polder reclamation" initially to meet the needs of agricultural production to an integration of embankment construction, reclamation area foundation reinforcement, and land improvement projects. , is a comprehensive development and utilization model of land resources that mainly meets the functional needs of industrialization such as ecology, tourism, ports and urbanization construction. Among them, the construction of dikes is the primary link to ensure the smooth implementation of tidal flat reclamation, an important barrier for shoreline protection of tidal flat land res...

Problems solved by technology

However, the sludge produced by dredging or dredging has the characteristics of high water content, high liquid limit, high compressibility, low strength, poor water permeability, slow consolidation rate, low shear strength, etc., and its engineering properties are extremely poor. How to fill the mold bag The rapid consolidation and hardening of silt to meet the needs of engineering construction is an urgent problem to be solved

[0004] The Chinese invention patent application with the publication number CN1818220A discloses a "bag-packed embankment filling method for solidified silt", but the process is complicated: the silt and cement need to be mixed uniformly before being bagged, and then the bags are piled up to form a dam. Finally, fill the silt in the enclosure, mix it with cement and mix it evenly

Such a complicated process is not conducive to improving construction efficiency, but also consumes a lot of manpower, making the construction workers labor intensive

In addition, this method needs to mix the mixture of silt and cement in the enclosure, and the foundation of the construction site is often too soft to bear the load, and vehicles cannot enter the construction site to directly transport the mixing machinery and equipment to the enclosure. The equipment is unloaded at the unloading point, and then manually carried by the construction personnel, which will undoubtedly increase the difficulty of construction and is not conducive to reducing costs; Soaking the bag at the root of the enclosure will make it difficult to solidify the sludge in the bag, which will not only greatly prolong the construction time, but may also cause the enclosure to collapse, posing a safety hazard
