[0004] However, for areas with large wind and waves, in order to ensure that the outer slope deformation of the breakwater under the action of waves is within the control range, and the deformation slope line does not exceed the dynamic equilibrium slope line, the weight of the face protection blocks must be large enough, sometimes up to 10t. It poses great challenges to the overall structure and transportation and installation methods; in addition, large wind and waves will affect the completion of the embankment section during construction, greatly reducing construction accuracy

Embodiment 1
[0034] Such as figure 1 As shown, this example provides a wide-shouldered breakwater, including: a slope embankment of trapezoidal structure, and the slope embankment is respectively provided with a core layer 1, an outer slope layer and a wide shoulder layer 4 from the inside to the outside, and the outer slope The layer is laid on the outer slope of the embankment core layer 1, and the wide shoulder platform layer 4 is arranged on the side of the outer slope layer away from the embankment core layer 1; the inner slope of the embankment core layer 1 is also provided with Two stones 5, an inverted filter layer 6 and a rear packing layer 7, the two stones 5 are arranged between the embankment core layer 1 and the inverted filter layer 6, and the inverted filter layer 6 is arranged between the two stones 5 and the rear Between the packing layers 7.
[0035] The height-to-width ratio of the embankment described in this example is 1:1.5 to 1:2. The thickness of the two stones 5 ...
Embodiment 2
[0040] Such as figure 2 As shown, this example also provides a transportation and installation method for a wide-shouldered breakwater, which is used to realize the transportation and installation process of the wide-shouldered breakwater as described in Embodiment 1, and includes the following steps:
[0041] Step S1, transport stone;
[0042] Step S2, push and fill the temporary embankment and embankment core layer 1 by Shantui bulldozer;
[0043] Step S3, using excavators and cranes to heighten, level and slope the block stones of the embankment core material, outer slope layer, two stones 5 and inverted filter layer 6;
[0044] Step S4, using a backhoe excavator to carry out preliminary throwing of the super-large rocks in the wide shoulder platform layer 4 within its working range, and then using a long-arm backhoe excavator to re-throw the rest of the area;
[0045] In step S5, the crane cooperates with the iron chain ring and the automatic shackle to perform fine pol...

Abstract
The invention provides a wide shoulder type bulwark and a transporting and installing method thereof. The wide shoulder type bulwark comprises a sloping bulwark of a trapezoid structure. The sloping bulwark is sequentially provided with a bulwark core layer, an outer slope layer and a wide shoulder layer from interior to exterior. The outer slope layer is laid on an outer slope of the bulwark core layer, and the wide shoulder layer is arranged on the side, far away from the bulwark core layer, of the outer slope layer. An inner slope of the bulwark core layer is further provided with two-layer stone, an inverted filter and a rear packing layer, wherein the two-layer stone is arranged between the bulwark core layer and the inverted filter, and the inverted filter is arranged between the two-layer stone and the rear packing layer. According to the wide shoulder type bulwark composed of the wide shoulder layer composed of extra-large rock blocks and a multi-grain-size rock block bulwark body, a reasonable construction technology and multiple heavy mechanical devices are adopted in the transporting and installing method of the wide shoulder type bulwark to achieve precise cooperation, and construction can be smoothly and precisely finished. Meanwhile, the construction progress is fast, and the influence of the wind wave action on the section of the finished bulwark body in the construction period is small.
Description
technical field [0001] The invention relates to a breakwater, in particular to a wide-shoulder breakwater and a transportation and installation method for the wide-shoulder breakwater. Background technique [0002] The slope type breakwater is the most commonly used structural type for harbor breakwater engineering. Wide-shouldered slope breakwater means that a platform with a certain width slightly higher than the design high water level is set on the seaside side. Under certain wave action, the section of the embankment is allowed to deform and gradually adapt to the local wave dynamic conditions to form a similar A new type of slope breakwater with S-shaped dynamic balance section. [0003] Compared with the traditional concrete artificial face protection block slope embankment, it has the advantages of not needing concrete artificial face protection blocks, making full use of stone materials, significantly reducing the cost, and less damage under the action of super-lar...
