Description
Technical Field
The utility model belongs to the technical field of urban tunnel engineering construction of river-related sections, and particularly relates to a split socket type steel frame caisson structure.
Background
When the urban tunnel is involved in river construction, the cofferdam of the river is generally in the form of double-row steel sheet piles, but in the actual construction process, the cofferdam possibly intersects with an electric power calandria, a sewage pipe and the like so that the cofferdam cannot be enclosed, and some gaps are larger, so that a device is needed to be designed for local plugging.
Disclosure of Invention
In order to solve the problems, the utility model discloses a split socket type steel frame caisson structure, which is simple and practical in structure, convenient to operate and simple to manufacture, and can rapidly plug gaps.
In order to achieve the above purpose, the technical scheme of the utility model is as follows:
a split socket type steel frame caisson structure comprises an upper frame and a lower frame,
the upper frame is a frame structure formed by profile steel, and at least 4 steel pipes extend downwards to form an upper upright post;
the lower frame is a frame structure formed by section steel, and a lower upright post corresponding to the upper upright post is arranged on the lower frame;
the front end surfaces of the upper frame and the lower frame are provided with a baffle plate.
As an improvement of the utility model, the upper frame is a square frame structure formed by combining an upper longitudinal beam, an upper cross beam and an upper vertical rod.
As an improvement of the utility model, the lower frame is a square frame structure formed by combining a side sill, a lower cross beam and a lower upright.
As an improvement of the utility model, the upper upright post and the lower upright post are sleeved.
As an improvement of the utility model, the thickness of the separator is 8mm.
As an improvement of the utility model, the outer sides of the upper longitudinal beams of the upper frame are provided with limit stops, and the limit stops are arranged at the outer sides of the two ends of the upper frame.
The beneficial effects of the utility model are as follows:
according to the split socket type steel frame caisson structure, the steel frame caisson is divided into the upper split structure and the lower split structure, the steel pipe socket type is adopted for connection, and the limit stop block is arranged in the steel plate trapezoid groove to prevent the caisson from translating and sinking excessively, so that the split socket type steel frame caisson structure is simple and practical in structure, simple to manufacture and capable of rapidly plugging gaps.

Description of the embodiments
The present utility model is further illustrated in the following drawings and detailed description, which are to be understood as being merely illustrative of the utility model and not limiting the scope of the utility model.
As shown in the figure, the split socket steel frame caisson structure is used for plugging a larger cofferdam notch (6 m).
Considering that the caisson is heavy and the integral hoisting is difficult, the steel frame caisson is divided into an upper frame 1 and a lower frame 2, and the upper frame extends downwards by at least 4 steel pipes to form an upper upright post 3; a lower upright post 4 corresponding to the upper upright post is arranged on the lower frame; the upper frame 1 and the lower frame 2 are connected in a steel pipe socket joint mode, a member main body is made of a section bar, a partition board 5 is arranged on the front end faces of the upper frame and the lower frame, the partition board 5 is made of a steel plate with the thickness of 8mm, and the steel brand is Q235B. The overlap joint length of the steel frame caisson and the steel sheet pile is 1.5m, and HN 700 multiplied by 300 section steel is arranged at the opening part of the door opening to locally strengthen the row piles.
The upper frame 1 is a square frame structure formed by combining an upper longitudinal beam 6, an upper cross beam 7 and an upper vertical rod 8.
The lower frame is a square frame structure formed by combining a lower longitudinal beam 9, a lower cross beam 10 and a lower vertical rod 11.
In order to prevent the caisson from translating and sinking excessively, a limit stop 12 is arranged at the outer side of the upper frame 1 and close to the end part, and in order to improve the impervious effect, a grouting pipe is additionally arranged at the gap of the lap joint section. In addition, in order to prolong the seepage path, a gabion or a soil bag foot protector is arranged on the water facing side to prevent scouring, a certain soil side pressure is provided, and a certain soil filling area is required to be arranged on the water backing side.
It should be noted that the foregoing merely illustrates the technical idea of the present utility model and is not intended to limit the scope of the present utility model, and that a person skilled in the art may make several improvements and modifications without departing from the principles of the present utility model, which fall within the scope of the claims of the present utility model.
