Specific embodiment
Specific embodiment of the present utility model is described below, in order to facilitate understanding by those skilled in the art
The utility model, it should be apparent that the utility model is not limited to the range of specific embodiment, to the common skill of the art
For art personnel, if various change the attached claims limit and determine the utility model spirit and scope in,
These variations are it will be apparent that all utilize the innovation and creation of the utility model design in the column of protection.
As shown in Fig. 1 ~ 3, which includes corner pile 1, skirt piles 2 and horizontally-supported 3；Corner pile 1 and side
The vertical insertion ground 6 in one end of stake 2, corner pile 1 and skirt piles 2 are the steel pipe of outer diameter 800mm, wall thickness 10mm.Horizontally-supported 3
Both ends are respectively equipped with the first steel plate washer 5, and corner pile 1 connects that there are two the first steel plate washers on two different directions of same level
5, corner pile 1 is respectively connected with the first steel plate washer 5 in multiple and different horizontal planes.First steel plate washer 5 is the arc steel plate for being bonded corner pile 1
Convenient for being uniformly distributed for horizontal supporting force.
What is connected between adjacent level support 3 has bearing diagonal 4, if the horizontally-supported 3 side connections far from bearing diagonal 4 has
Dry skirt piles 2 are equipped with the second steel plate washer 501, the tie point face of bearing diagonal 4 and horizontally-supported 3 between skirt piles 2 and horizontally-supported 3
Second steel plate washer 501.To enable the extruding force from skirt piles 2 to be directly conducted to by the second steel plate washer 501 and horizontally-supported 3
Bearing diagonal 4 prevents horizontally-supported 3 lateral force excessive and deforms.
All backing materials are all made of Q235B steel.
From in actual work progress, the deep-well retaining wall steel structure support construction method is as follows:
Corner pile 1 is vertically squeezed into ground 6 using impact drill or Spiral digging machine, corner pile 1 has 4 altogether, between the center of adjacent corner pile 1
Away from being 4.2 meters.
Skirt piles 2 are vertically beaten along side of two neighboring 1 line of centres of corner pile far from corner pile 1 using impact drill or Spiral digging machine
Enter ground 6.It is horizontally-supported 3 reserved place to the direction offset 80mm far from 1 line of centres of corner pile when squeezing into skirt piles 2
It sets.
It is the square steel tube of 160mm*160mm*5mm horizontally-supported 3, both ends, which pass through, is welded to connect the first steel plate washer 5, and first
Steel plate washer 5 is 350mm*350mm curved plate, and the first steel plate washer 5 passes through with corner pile 1 at the construction field (site) to be welded to connect, welding
Position is two sides axially contact with corner pile 1.Bearing diagonal 4 is the square steel tube of 140mm*140mm*5mm, is propped up with adjacent level
Support 3 welds together at the scene, and bearing diagonal 4 requires to be fully welded with the port surrounding that horizontally-supported 3 connect, to guarantee that support is strong
Degree.The second steel plate washer 501 is added between horizontally-supported 3 and skirt piles 2, and different-thickness or more can be embedded according to the size in gap
A second steel plate washer 501, come guarantee horizontally-supported 3 can for skirt piles 2 provide it is enough horizontally-supported.Final rectangular steel construction shape
At first level supporting surface 301.
6 or less excavated to the ground along first level supporting surface 301, to the ground 6 or less the depth excavated be no more than 16 meters, and
It is stepped up horizontal support surface.It is arranged when along first level supporting surface 301,6 or less are excavated to 4.5 meters of depths to the ground 4 meters of depths
Second horizontal support surface 302 is arranged third horizontal support surface 303 8 meters of depths when being excavated to 8.5 meters of depths, is excavated to 12.5 meters
The 4th horizontal support surface 304 is set 12 meters of depths when deep, is excavated to horizontal in 14.8 meters of depths settings the 5th when 15.3 meters of depths
Supporting surface 305.
The quantity of horizontal support surface can suitably be reduced according to the depth of construction, the spacing between adjacent level supporting surface
No more than 4 meters, the spacing between last one of horizontal support surface and road horizontal support surface second from the bottom is controlled within 2.8 meters.It applies
Excavating during work should stop excavating immediately when supporting the position of following 500mm to design level, and construction level support immediately 3
It, must not the flat support 3 of one-off construction and bearing diagonal 4 after Cheng Jing with bearing diagonal 4.
It excavates the depth that corner pile 1 and skirt piles 2 after finishing are buried in soil and is not less than 0.8 meter.4 after construction, by
Step backfill.When being backfilling into 500mm under horizontal support surface, the horizontal support surface is removed, is returned after must not disposably removing all supports
It fills out.
Corner pile 1 and skirt piles 2 are extracted from ground 6 finally and complete construction.
