Embodiment 1

[0040] Such as figure 1 As shown, the present invention provides a river dredging method. The method includes the following steps:

[0041] Step S1: setting the first cofferdam for the section of the river channel, and pumping out the water in the first cofferdam.

[0042] Dams and cofferdams are built in sections of the river course, and the sectioned river courses are set according to the actual situation on site. The first cofferdam is filled with soil, the top width is 6m, and the slope on both sides is 1:1. The earthwork of the first cofferdam is excavated from the muck field and transported to the filling site of the first cofferdam by dump truck. The excavator pushes and rolls the filling into the river until it closes and reaches the design elevation and top width.

[0043] Step S2: Clean up the muck in the river channel.

[0044] Muck includes trash and rocks. Because there are many miscellaneous trees, branches, and domestic garbage on the side slope of the rive...

Embodiment 2

[0048] In yet another embodiment of the present invention, the river channel dredging method in this embodiment is similar to the river channel dredging method in the first embodiment, and the similarities will not be repeated, and only the differences will be introduced.

[0049] In this embodiment, it is disclosed that step S1 specifically includes the following steps:

[0050] Step S11: Excavate the earthwork from the muck field, transport it to the first cofferdam, and then push and roll it into the river channel for filling by the excavator.

[0051] In order to prevent the pressure difference on both sides of the first cofferdam during and after the pumping process, causing the first cofferdam to shift or collapse, wooden piles can be added at the weak points such as the closing point of the first cofferdam to fix the foundation, with a distance of 1m, double Arrange in a quincunx shape, choose the length of the piles according to the actual situation, with a diameter of...

Abstract

The invention discloses a river dredging method. The method comprises the following steps of: step S1, setting a first cofferdam to the river section, and extracting the water in the first cofferdam;step S2, cleaning the muck in the river; step S3, discharging the sludge in the river. The method disclosed by the invention comprises: firstly, setting a first cofferdam to the river section, and extracting the water in the first cofferdam; next, cleaning the muck in the river; finally, discharging the sludge in the river. The method disclosed by the invention can discharge the sludge in the river, and solve the problem of clogging of the river.

Description

technical field [0001] The invention relates to the technical field of river channel cleaning, in particular to a river channel dredging method. Background technique [0002] As an important part of the urban ecosystem, urban rivers not only have the functions of providing water sources, transportation and shipping, flood control and drainage, but also have ecological environmental effects such as regulating climate and reducing pollution. However, in the process of rapid urbanization, urban rivers are faced with silting problems caused by human occupation, destruction of ecological green plants on both sides of river embankments, and deterioration of river water quality, resulting in the degradation of urban river functions. [0003] Therefore, how to solve the silting problem of the river course is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide ...
