Construction method of rubble mounding for sea-reclamation

Abstract

The embodiment of the invention discloses a construction method of rubble-mounding for sea-reclamation, which comprises the steps of: (a) arranging a floating platform along the water surface in front of a dumped rockfill dike; (b) delivering soil and rubbles to the floating platform by construction vehicles, and pouring the soil and rubbles out; (c) moving the floating platform away when the soil and rubble pile approaches the floating platform; and (d) pouring the soil and rubbles towards the dumped rockfill dike side slope above the dumped rockfill dike directly by the construction vehicles. In the construction method of rubble mounding for seal-reclamation, the floating platform is adopted for auxiliary construction, the floating platform is arranged at the front edge of the dumped rockfill dike, the construction vehicles deliver the soil and rubbles onto the platform, and then rubble mounding is carried out so that the rubble mounding position is close to the outer side, and the soil and rubbles subside and fall directly on a place close to the slope toe. When the soil and rubbles are filled on the platform to a certain height, a new side slope is formed at the outer side of the original side slope, thus the original side slope is compacted and fastened. After the floating platform is moved away, the soil and rubbles are directly poured toward the dumped rockfill dike side slope above the dumped rockfill dike by the vehicles, therefore, the side slope formed by the poured rubbles has a slight gradient and is compacter and firmer, and is not easy to cause landslide, thus the safety of the construction vehicles is ensured.

Description

technical field [0001] The invention relates to the technical field of sea reclamation, and more specifically, relates to a construction method for riprap sea reclamation. Background technique [0002] Reclamation refers to the need to push the coastline forward due to the shortage of land use or the need to cooperate with planning, and expand the land area by artificial construction. Some coastal cities need to open up new land to the coast because of the pressure of factors such as limited construction land and economic development. [0003] During the construction process of riprap reclamation, trucks generally transport earth and rocks to the front of the reclamation area and dump them, so that the dam is gradually extended outwards to achieve the purpose of land reclamation. [0004] see figure 1 , figure 1 It is a schematic diagram of the construction method of riprap sea reclamation in the prior art. Among them, 1 is the construction vehicle, 2 is the land, 3 is t...

AI Technical Summary

Problems solved by technology

[0005] The existing method of riprap reclamation has the following problems: due to the direct dumping of earth and rocks at the front of the dam 3, the earth and rock will naturally slide down on the slope of the front of the dam 3 to form the slope 6 of the dam, resulting in the slope 6 of the front of the dam 3. The upper slope is steep and loose, so when the riprap construction vehicle 1 is working at the front of the dam 3, when the side slope 6 is subjected to the heavy pressure and vibration of the vehicle, landslides are prone to collapse at the position of the easy-to-slide part 4. fatal accident
