Problems solved by technology

There are relatively obvious defects in the above-mentioned silting promotion projects: a large amount of rocks are required in the construction of the project, and the amount of throwing is huge, so that in areas where the supply of rocks is tight, there will be a problem of increased construction costs due to the difficulty in obtaining construction materials; After the block stones are thrown, the silt-promoting embankment formed by it has a low porosity and a large self-weight. In this way, in the construction of silt-promoting soft soil foundation, because the block stone silt-promo

Embodiment Construction

[0026] In order to further understand the content of the invention, characteristics and effects of the present invention, the following examples are described in detail as follows:

[0027] See figure 1 , construction method of the present invention comprises the following steps:

[0028] (1) interlocking block prefabrication, prepare the interlocking block that forms software row;

[0029] (2) row body sewing, the interlocking block is sewn into a soft body row;

[0030] (3) Laying of the interlocking block soft row, using a laying boat to lay the soft row obtained in step (2) on the embankment; in this step, the overlapping width of two adjacent soft row laying is greater than or equal to 5m.

[0031] (4) Positioning and spreading of the hoisting ship, the hoisting ship equipped with GPS system will be parked along the embankment axis of the embankment; the GPS system here can be selected as the GPS-RTK system with centimeter positioning accuracy to ensure the accuracy of ...

Abstract

The invention belongs to the technical field of sea reclamation siltation promotion and particularly relates to a method for constructing a sea reclamation siltation promotion dyke by using perforated blocks. The method comprises the following steps of (1) prefabricating interlocking blocks, i.e. preparing the interlocking blocks which form soft mattresses; (2) sewing the mattresses, i.e. sewing the interlocking blocks into the soft mattresses; (3) paving the soft mattresses of soft mattresses, i.e. using an arrangement ship to pave the mattresses obtained in the step (2) onto a dyke foundation; (4) positioning and distributing a lifting ship, i.e. positioning the lifting ship with a GPS (Global Positioning System) system along dyke axis of the siltation promotion dyke; (5) mounting the perforated blocks on the bottom layer, i.e. using a vertical lifting tool to carry out place mass centers of the perforated blocks on the bottom layer at preset positions; (6) performing dumping fill on banket rock mounds, i.e. performing dumping fill on banket rock mounds on the two sides of the perforated blocks on the bottom layer, and laterally supporting the perforated blocks on the bottom layer; (7) performing dumping fill on over two layers of perforated blocks, i.e. performing random posture stacking on the perforated blocks above the perforated blocks on the bottom layer, wherein the projections of two adjacent perforated blocks on the horizontal plane are quincunx, and the upper layer of perforated blocks are obliquely embedded in clearances of the lower layer of perforated blocks.

Description

technical field [0001] The invention belongs to the technical field of sea reclamation and siltation promotion, and in particular relates to a construction method for sea reclamation and siltation promotion embankment by using hollow blocks. Background technique [0002] Sea reclamation is an effective way to solve the contradiction of land resource shortage in coastal areas. With the dwindling of high beach resources and the increasing engineering experience, sea reclamation projects are gradually developing from tidal flat areas to shallow sea areas. Before land reclamation construction in shallow sea areas, the silt-promoting project is generally carried out first. The silt-promoting project can accelerate the sedimentation effect of the sediment. The silt-promoting dike project can reduce project investment and reduce project risks. Therefore, the silt-promoting dike project has become a sea reclamation project One of the keys to geoengineering. [0003] Existing silt-p...
