Airtight earthwork throwing and filling construction process

Abstract

The invention relates to an airtight earthwork throwing and filling construction process. The airtight earthwork throwing and filling construction process comprises the following steps of (S1) preparing for construction: collecting basic data, and defining a measurement control point and a reference point of a project; (S2) dividing a soil sampling area; (S3) constructing soil retaining plates: constructing a plurality of soil retaining plates near the side, which deviates from the open sea side, of a main levee, and forming gaps between every two adjacent soil retaining plates; (S4) excavating mud flat sludge: excavating in a shallow excavation and wide extraction mode; (S5) performing airtight earthwork throwing and filling construction: firstly, pumping airtight earthwork in throwing and filling areas between the soil retaining plates and the main levee, then throwing and filling the airtight earthwork in throwing and filling areas between the adjacent soil retaining plates, finally, throwing and filling the airtight earthwork in throwing and filling areas between a sub levee and the soil retaining plates, and propelling according to the principle of thin-layer alternate addingand balanced ascending; (S6) detecting and supplementing to throw; and (S7) performing slope arrangement: repairing the slope of the airtight earthwork after the airtight earthwork is solidified. Theconstruction process of the airtight earthwork has the effect of improving the anti-seepage performance of the main levee.

Description

technical field [0001] The present application relates to the technical field of air-tight earthwork construction, in particular to an airtight earthwork throwing filling construction technology. Background technique [0002] The development and utilization of tidal flat land resources can effectively alleviate the conflict of demand for land resources. Deep water reclamation has become the mainstream development direction of coastal industrial belt development. Deep water reclamation projects have begun to expand to the open sea and enter deep water areas. ~-10 meters mainly. In the deep water area, there are high waves and high tides. In order to ensure the stability of the cofferdam, a large area of ​​shallow soil is taken from a large area more than 100 meters from the slope footline of the seawall and thrown between the main embankment and the sub-dike. [0003] The air-tight earthwork is a trapezoidal earth dam set between the main embankment and the sub-dike of the d...
