Dredger fill loss control construction technique

Abstract

The invention relates to a dredger fill loss control construction technique. The technique includes the steps of (1) building a sluice-box-type drainage outlet for a dredger fill area, wherein sluice boxes are arranged side by side at the preinstalled drainage outlet of the dredger fill area, the total width of the sluice box group is larger than the width of the drainage outlet so as to cover the drainage outlet transversely; (2) arranging drainage pipes at the drainage outlet, wherein the multiple drainage pipes are arranged side by side transversely, the inner ends of the drainage pipes are connected to the bottoms of the sluice boxes while the outer ends extend to a drainage area; (3) arranging a non-bottoming-type mud blocking screen at the front of the drainage outlet, wherein the arc mud blocking screen is arranged around the inner side of the drainage outlet in the dredger fill area, the mud blocking screen comprises a support and filter cloth mounted on the support, the filter cloth is used for filtering mud, the intercepted high-concentration mud is fully precipitated and then flows from the underneath of the filter cloth to an overflow weir where the mud is blocked and precipitated, and clear water at the upper layer flows out and is drained through the drainage pipes. The dredger fill loss control construction technique has the advantages of achieving control of the amount of dredger fill mud loss, shortening the construction period of a project and improving the profit.

Description

technical field [0001] The invention belongs to the technical field of dredging construction, and in particular relates to a dredging and filling loss control construction technology. Background technique [0002] In order to meet the needs of port development, it is necessary to carry out dredging of the port area and waterways and land reclamation. In the design and construction of dredger reclamation, there are many problems such as easy silting in the construction area, large settlement in the dredger reclamation area, difficulty in determining the elevation of dredger reclamation, and serious loss. The loss control during the filling process is an important indicator to determine the profit of the project. Therefore, how to reduce churn becomes the key to increasing profit points. [0003] After the mud discharged to the reclamation area through the mud discharge pipe is settled, part of the mud forms the foundation of the road area, and the upper water body needs to ...

AI Technical Summary

Problems solved by technology

Existing dredging and dredging construction techniques are not effective in controlling the loss of mud. A large amount of mud flows out of the dredging area with drainage without sedimentation, resulting in increased dredging loss, prolonging the project cycle and reducing eye-catching profits.
