Embodiment Construction

[0020] Such as figure 1 , 2 The device shown in the method for installing and leveling a caisson on the submarine ground is that the structure of the caisson is installed and leveled on the submarine ground: there are vertical through holes on the four corners of the caisson, and each channel on the surface of the caisson There are support frames for back pressure beams on both sides of the holes, rectangular holes passing through the back pressure beams at the upper end of each support frame, and back pressure beams through the through holes on the support frames on both sides of each through hole. Each through hole is equipped with a telescopic pillar, which is composed of a lower pillar section and an upper pillar sleeve. On both sides of the tube wall of the lower pillar section and the upper pillar sleeve, there are matching vertical adjustment holes; Jacks are installed under the back pressure beam and the upper end face of the telescopic pillar.

Abstract

The invention relates to a method for installing and leveling a caisson on the seabed ground. The caisson with a caisson height adjusting device is installed and leveled on the seabed ground, the elevation of each corner point is adjusted with a jack, a gap between the bottom of the caisson and the seabed ground is plugged with bagged concrete or bagged mortar, a closed space is formed between the bottom face of the caisson and the seabed ground and filled with concrete or mortar, and a caisson foundation is formed. By means of the method, the caisson can be rapidly installed and leveled on the rugged seabed ground, and the flat caisson foundation can be rapidly constructed. The method is simple and easy to operate.

Description

Technical field [0001] The invention belongs to the technical field of water conservancy, port, ocean, coast and offshore engineering construction, and particularly relates to a method for installing and leveling a caisson on the seabed ground. Background technique [0002] The caisson gravity structure is a traditional hydraulic building structure. Because the caisson can be prefabricated on land and hauled and installed on the water, it reduces the workload of water construction, so it has the characteristics of fast construction. In recent years, the need for offshore port engineering and rapid land formation has become more and more urgent, and the construction speed of the caisson gravity structure has also attracted more and more attention. [0003] However, due to the distance from the land, offshore projects often face a lack of filling materials, especially the blocks used as the foundation of the caisson are often not available nearby. How to quickly build a flat caisson...
