Embodiment Construction

[0019] The technical solutions of the present invention will be further explained below with reference to the accompanying drawings.

[0020] see Figure 1-3 , the present invention provides a grouting device suitable for the solidification of the soil around the underwater pile group, including: an upper structural section 1, a lower structural section 2, a blade foot 3, a floating tank 4, and a grouting rod 10. The upper structural section 1 and the lower structural section 2 are all rectangular steel structures, the upper structural section 1 is arranged on the lower structural section 2, and the lower structural section 2 is provided with a blade foot 3, the blade foot 3 is a steel structure with sharp The corners face downwards, which is beneficial for the lower structural section 2 to be plunged into the underwater soil. The side wall of the upper structure section 1 is provided with a floating and sinking tank 4, and the floating and sinking tank 4 has a built-in lique...

Abstract

The invention discloses a grouting device suitable for solidifying soil around underwater pile groups, and relates to the technical field of grouting. The grouting device includes: an upper structure section, a lower structure section, a blade foot, a floating tank, and a grouting rod. The upper structure section is arranged on the lower structure section, and a blade foot is provided below the lower structure section. The side wall of the upper structure section is provided with a buoyant sink, the lower structure section and the upper structure section are provided with pile foundations, and the side wall of the lower structure section is provided with an upper slurry outlet and a lower slurry outlet. The upper structure section is provided with a side grouting pipe and a grouting rod, and the side grouting pipe is connected with the upper grout outlet and the lower grout outlet. The grouting device of the present invention forms a pile group construction cofferdam through the upper structure section and the lower structure section, which can solidify a wide range of soil including between piles and around piles, increase the solidification depth of the soil, and improve the horizontal bearing capacity of pile foundations and The anti-scouring ability of the soil around the pile, the grouting device has the characteristics of continuous and convenient construction, and at the same time, the upper structure section can be reused.

Description

technical field [0001] The invention relates to the technical field of grouting, in particular to a grouting device suitable for solidification of soil around underwater pile groups. Background technique [0002] Pile foundation is an important form of bridge foundation, and it is often used in the arrangement of group piles in engineering practice. In the construction of bridges, how to effectively carry out the pile foundation construction is an important engineering problem. In the long-term use process after the completion of construction, the erosion of water flow will cause erosion loss of the soil around the pile, which will have a huge adverse effect on the bearing performance of the pile foundation. [0003] In the prior art, steel cofferdams need to be installed in the construction of underwater pile foundations, and the water in the cofferdams is drained to obtain dry construction work space, and then related operations are carried out in the cofferdams. How to ...
