Embodiment Construction
[0060] In order to make the content and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0061] The concrete steps of the vertical dike that uses the present invention to build are as follows:
[0062] Step 1: Select the bearing layer and design the section structure of the vertical embankment. When selecting the bearing layer and designing the section structure of the vertical embankment, the characteristics of the foundation treated by fine blasting and silting should be fully considered to ensure the structural stability of the vertical embankment.
[0063] Step 2: Stone filling. Natural mixed graded stones can be used for throwing and filling stones. The stones are required to be fresh and complete, and the mud content should not exceed 5%. The throwing and filling methods can be water throwing, land throwing, and water and land mixed thro...

The invention provides a method for building a vertical breakwater, which uses a sludge soft foundation as a foundation and processes the sludge soft foundation by using a fine blasting toe-shooting method. The method specially comprises the following steps of: selecting a supporting layer and designing a cross section structure of the vertical breakwater; throwing-filling stones; carrying out exploding-filling on the sludge soft foundation; throwing-filling and carrying out exploding-ramming on a foundation bed; and carrying out normal follow-up treatment, wherein in the exploding-filling treatment, the head and two sides of a dam are exploded simultaneously, so that the head and the both sides of the dam drop simultaneously. The vertical breakwater built by using the method disclosed by the invention has the advantages of reasonable structure, good stability, low cost price, easiness of construction, rapid construction speed and obvious economic benefits, and meet the modern technique requirements of great, fast, good and saving effects.
Description
technical field [0001] The invention relates to the technical field of vertical dikes, in particular to vertical dikes with relatively large water depth and silt soft foundation. Background technique [0002] Vertical embankment is a relatively common hydraulic structure in port engineering, which belongs to a form of breakwater. The main function of the vertical embankment is to prevent waves from attacking the port waters and create calm waters in the port for ships to berth and other operations. In addition to the anti-wave function, the vertical embankment also has the functions of sand blocking, ice blocking, reverse flow, and the inner side doubles as a wharf. [0003] The advantage of the vertical embankment is that it uses less material, the maintenance workload is small, and the inner side can also be used as a wharf; the disadvantage is that it has higher requirements on the bearing capacity of the foundation, is more sensitive to uneven settlement of the foundati...
