Embodiment Construction

[0048] The following examples can enable those skilled in the art to understand the present invention more comprehensively, but the present invention is not limited to the scope of the described examples.

[0049] Such as Figure 1 to Figure 4 The jacket of a riprap system shown includes a jacket frame 1, a box girder structure 2 and a corbel structure; the box girder structure 2 is embedded on the jacket frame 1, and the corbel structure is arranged on the jacket On the overall structure formed by the frame 1 and the box girder structure 2.

[0050] The jacket frame 1 includes a transom plate 11, a port and starboard plate 12 and an end plate frame; the port and starboard plates 12 are vertically arranged on both sides of the transom plate 11 to form a U-shaped structure; the end plates The racks are arranged at both ends of the U-shaped structure.

[0051] The box beam structure 2 includes a port box structure 21, a starboard box structure 22, a bottom box structure 23 and...

Abstract

The present invention relates to a novel riprap system jacket and its construction process, which is characterized in that: it includes a jacket frame, a box-shaped beam structure and a corbel structure; the box-shaped beam structure is embedded in the jacket frame, and the corbel The structure is set on the overall structure formed by the jacket frame and the box girder structure; the specific construction steps include S1: construction of the jacket frame; S2: construction of the box girder structure; S3: construction of the corbel structure; S4: overall assembly; riprap All stages in the construction of the system jacket take into account the addition of welding shrinkage allowance and anti-deformation, prefabricate strictly according to the components, and strengthen the control of key assembly dimensions; the order of positioning and welding is strictly in accordance with: from bottom to top, from the inside The principle of going out is to carry out the order of step-by-step installation; this process is convenient for welding, has high closing precision, and can improve welding quality and work efficiency.

Description

technical field [0001] The invention relates to the technical fields of ocean engineering and shipbuilding, in particular to a rock-riprap system jacket and a construction process thereof. Background technique [0002] The Hong Kong-Zhuhai-Macao Bridge is a world-renowned super project, among which the submarine tunnel project is the most technically difficult and has created many of the world's best. The subsea tunnel of the Hong Kong-Zhuhai-Macao Bridge adopts the first-laying method. Compared with the two immersed tube tunnel projects in Denmark's Oresund Strait and South Korea's Busan, which also use the first-laying method, the total workload of riprap leveling is large. , the total amount of crushed stone laid is 363,000 m³; the leveling slope of the crushed stone bed varies greatly, with a total of 29 slopes; the water depth varies greatly, and the water depth of the bed is 8-45m; the leveling process and leveling accuracy requirements of the immersed tube foundation ...
