Supplementary water barge launching construction method

Abstract

A supplementary water barge launching construction method is characterized in that the construction method comprises the following steps: 1, arranging four hoists at four corners of a barge body; 2, constructing only one wire rope guiding ground anchor point at the bank of a river, using two porters as guide ground anchor points at the west bank of the river, and arranging a concrete ground anchor at the east bank of the river; and 3, allowing two anchor chains of the porters A and B not to launch with the barge, throwing two Hall anchors in water, allowing the barge body to move to the bank of the river, carrying out hoisting steel bridge connection, allowing the barge body to move to a predetermined position, and using the hoists in the barge to tract the anchor chains at the bank in place. The construction method has the advantages of high efficiency, engineering amount reduction, convenient and fast construction, and construction cost saving.

Description

technical field [0001] The invention relates to the field of engineering construction, aiming at the optimal construction under background conditions such as no auxiliary tugboat and no good geographical environment during the launching process of barges. Background technique [0002] Barge launching construction generally uses the ship airbag launching process, which requires the use of auxiliary tugboats or multiple traction equipment to continuously change the direction of the barge in the water during the launching process to achieve final and accurate positioning. [0003] The construction plan given by the manufacturer is: after the pontoon hull is launched with 4 airbags, 4 winches are required to be arranged on the east and west banks of the river, and 8 winches are used to assist the pontoon to anchor at 4 anchor points, and then move to the shore. Move to the predetermined position after hoisting and connecting the steel approach bridge. The construction difficult...

AI Technical Summary

Problems solved by technology

A total of nearly 2,000m of wire rope winding requires a lot of manpower and material resources, and aquatic plants, silt, and debris in the river water form resistance during wire rope winding, which brings many uncertain and unsafe factors

[0006] 3. Construction on the east bank of the river requires large-scale removal of vegetation. There are a large number of shrubs, bamboos and other vegetation in the open area on the east bank of the river, especially around the preset position of the hoist and extending to the river bank, making it difficult to ensure smooth progress of the construction.

[0007] 4. It is not easy to set up temporary construction power supply for the 4 winches arranged on the east bank of the river, and the cables need to be released overhead from the river surface. During the barge construction, the river water has overflowed the 105m wide dam and the current is turbulent, so there are certain risks in the construction

[0008] 5. The wire ropes of the 4 winches on the other side of the river have to cross the turbulent river of more than 60 meters to drag the barge. It is difficult to ensure that the wire ropes of multiple winches will not interfere and get mixed together

[0009] There are too many uncertain factors in this plan, and it cannot guarantee that the construction safety is under control.

If the water level of the river surface rises a lot during the construction in the rainy season, the original plan cannot be implemented smoothly.
