Abstract
The utility model relates to a foundation pit supporting structure suitable for a basin type excavation method. The foundation pit supporting structure suitable for the basin type excavation method comprises a foundation pit excavated in a basin shape, and a central structure, wherein the central structure is located in the middle position of the foundation pit, supports are arranged inside the foundation pit all around, a bracket is arranged on the top of a top plate of the central structure, and the bracket and the supports around the foundation pit are connected and supported through steel tube braces. According to the foundation pit supporting structure suitable for the basin type excavation method, an existing foundation pit supporting structure is used as a power transmission component so that investment is saved to a large extent, and a construction period is shortened to a large extent; and moreover, the steel tube braces are recyclable building materials, and therefore the foundation pit supporting structure suitable for the basin type excavation method has a quite good environmental protection property and significant economic benefits.
Description
Technical field
The technical program belongs to the building foundation pit supporting technical field, specifically a kind of foundation pit supporting construction pattern that is applicable to the basin excavation mode.
Background technology
In foundation pit supporting project, for area ultra-large type project, take conventional Foundation Pit, have a lot of deficiencies from economy and reasonability, and there are a lot of inconvenience in the construction of pattern foundation pit supporting structure.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the technical program proposes a kind of foundation pit supporting construction that is specially adapted to the basin excavation mode, and concrete technical scheme is as follows:
A kind of foundation pit supporting construction pattern that is applicable to the basin excavation mode comprises foundation ditch and the center structure of basin excavation, and the center structure is positioned at the centre position of foundation ditch, is provided with supporting around the foundation ditch inside; The top board of described center structure top arranges bracket, is connected supporting by steel pipe support between the peripheral prop of bracket and foundation ditch.
The longitudinal cross-section of described bracket is right-angled trapezium, and described steel pipe top is at face corresponding to right-angle side.
Described bracket comprises concrete and interior reinforcing bar thereof, and bracket is connected by the bar planting mode with the top board of center structure; Described reinforcing bar has many, and each root reinforcing bar is vertically implanted the center structure.
On described steel pipe and the bracket contact surface steel plate is set; Steel plate is embedded in the bracket front, is implanted with reinforcing bar in the bracket of steel plate position, and this reinforcing bar becomes " door " font, and the reinforcing bar of the both sides of " door " font is perpendicular to plane, steel plate place.
The top planes angulation of the hypotenuse of described right-angled trapezium and center structure is the obtuse angle, and angular dimension is decided according to the actual loading situation.
In the foundation pit supporting project of the prior art, for area ultra-large type project, take the mode construction foundation pit engineering of basin excavation, treat that structure construction in center finishes and reach requirement of strength, at the existing structure top bracket is set, set up support.
This structure as Force transmission parts, has been saved investment, duration with existing structure to a great extent, and steel pipe support is recyclable building materials, and the feature of environmental protection is very strong, remarkable in economical benefits.
Description of drawings
Fig. 1 is this routine structural representation;
Among the figure, bracket 1, steel pipe 2, beam 3, floor 4, reinforcing bar 5, steel plate 6.
The specific embodiment
The technical program is further specified as follows below in conjunction with accompanying drawing and the specific embodiment:
A kind of foundation pit supporting construction pattern that is applicable to the basin excavation mode comprises foundation ditch and the center structure of basin excavation, and the center structure is positioned at the centre position of foundation ditch, is provided with prop around the foundation ditch inside; Described top of having finished the center structure is provided with bracket, is connected to form support system by steel pipe support between the prop of bracket and foundation ditch.
In this example, the longitudinal cross-section of described bracket is right-angled trapezium, and described steel pipe top is at face corresponding to right-angle side.The center structure comprises beam and floor, and floor and beam are built simultaneously and be integrated.
Described bracket comprise reinforcing bar and concrete, bracket is connected by the bar planting mode with the center structure roof; Described reinforcing bar has many, and each root reinforcing bar is vertically implanted the center structure.Length in reinforcing bar implantation floor and the beam is 40 times of bar diameter.The hypotenuse of described right-angled trapezium is 140 degree with obtuse angle that the floor level becomes.
Be separated with steel plate on described steel pipe and the bracket contact surface; Steel plate is embedded in the bracket side, is implanted with reinforcing bar in steel plate is sitting in the bracket of position, and this reinforcing bar becomes " door " font, and the reinforcing bar of the both sides of " door " font is perpendicular to plane, steel plate place.
