City internal river watercourse desilting construction process

Abstract

The invention relates to a dredging construction technology for urban inland rivers, which belongs to general river engineering, and has a patent classification number: E02B1 / 00. It is characterized in that the process includes the following steps: (1) underwater dredging, excavation and loading: (2) waterway transportation: (3) unloading and storage: (4) returning to the dredging site with an empty ship; The advanced technology is especially suitable for the dredging construction of urban inland rivers; the selection of equipment is reasonable, the movement is flexible, the operation is convenient, safe and efficient, the quality of dredging is reliable, and it meets the requirements of environmental protection. It is a construction technology integrating excavation, transportation and unloading operations.

Description

Technical field

[0001] The invention relates to a construction process for dredging urban inland rivers, belonging to an underwater dredging project of rivers, with a patent classification number: E02B1 / 00. Background technique

[0002] my country has a vast territory and many urban rivers. As the blood of the city, each river has different functions such as drinking, flooding, drainage, tourism, and shipping. Therefore, in order to maintain the cleanliness, permanent safety and vitality of urban rivers, it is necessary to timely dredge the urban inland rivers.

[0003] The dredging of urban inland rivers currently mainly relies on the following techniques:

[0004] (1) Mud pump dredging: The equipment adopts hydraulic dredge, which is composed of vertical mud pump mud conveying system, high pressure pump mud flushing system, power distribution system or diesel generator system. Simulate the principle of water flow scouring, use hydraulic action to excavate, transport and fill so...

Examples

Embodiment Construction

[0030] The present invention is described in detail by taking the dredging construction of an inland river in a large city with a population of about 8 million as an example.

[0031] According to the city's characteristics as a metropolis, a large population, and rivers passing through the city. Developed a detailed construction process: see the process flow chart figure 1 .

[0032] (1) Underwater dredging, excavation and loading:

[0033] Equipment: pontoon type pontoon, hydraulic grab, excavator.

[0034] Process: The three sets of equipment of pontoon type pontoon, hydraulic grab, and excavator are assembled into a pontoon type hydraulic grab machine at the dredging river site; the machine has two-way adjustable positioning piles and a self-adjusting positioning system. Excavation and dredging on the river course; the silt is loaded into the semi-bunk mud barge by hydraulic grab machine.

[0035] Detailed description: The pontoon type hydraulic grab machine is a pontoon with ...
