Problems solved by technology

Sand throwing and rock throwing are generally transported to the site by barge and then filled with a grab machine or manually. At present, the rough leveling of the rock riprap foundation bed can only be done by divers, and the fine leveling and ultra-fine leveling can be done with the help of mechanical equipment. but requ

Embodiment Construction

[0011] An example of the present invention is as follows: figure 1 with figure 2 The floating ship cabin row shown in the underwater riprap bed construction that integrates stone paving and leveling and continuous operation is formed by the front floating cabin, the rear floating cabin and the three intermediate floating cabins connected by connecting beams. The three intermediate floating cabins and The front side of the bottom of the rear floating cabin is provided with a rubble bed leveling scraper beam. The outer dimensions of the floating cabin row are 40m long and 20m wide, the front floating cabin is 10m high, the rear floating cabin is 8m high, and the middle floating cabin is 2m-6m high. Made of steel, the total weight of the device is about 350 tons. The volume of the sand and gravel hopper bin is 160~240m 3 , The width of the opening at the bottom of the hopper silo is determined by the width of the rubble bed. The total volume of the floating cabin that can generate b...

Abstract

A row of floating cabins for throwing rock in water to spread the foundation bed is composed of front and back floating cabins, three central floating cabins and the counecting beams at both sides of the said floating cabins. The inclined side plates of adjacent two floating cabins constitute a hopper cabin. The sand and rock with different sizes are sequentially thrown in water via relative hopper cabins. Under the floating cabin there is scraper beam for smoothing the foundation bed.

Description

Technical field [0001] The invention relates to a floating ship cabin row for continuous operation of stone laying and leveling in underwater stone dumping foundation bed construction. It belongs to the auxiliary equipment used for the construction of the rubble bed in the field of port and coastal engineering. Background technique [0002] In port and coastal engineering, there are many buildings that use underwater riprap beds, such as gravity piers, breakwaters with superstructures, and gravity piers of cross-sea bridges. The construction process of the underwater rock-rapid foundation bed is generally divided into foundation bed excavation, sand throwing or two-stone throwing (ie, small stones), large rock thrown, and rock-raped foundation bed leveling, and then the superstructure is installed. Among them, the leveling of the riprap bed is divided into rough leveling, fine leveling and extremely fine leveling. Sand and stone dumping are generally carri...
