Brief description of the drawings
Fig. 1 is a kind of ultra-deep steel pipe concrete continuous underground wall structure construction signal used in one embodiment of the present utility model
Figure.
Embodiment
As one embodiment of the present utility model as shown in Figure 1, introduced mainly in conjunction with Fig. 1 of the present utility model super
The construction procedure of deep steel pipe concrete diaphram wall and the steel pipe concrete continuous underground wall structure formed after the completion of construction method and construction
Construction.As shown in figure 1, the construction of the present utility model ultra-deep steel pipe concrete diaphram wall to be completed is included between steel-pipe pile (1), stake
Guide frame, filling concrete (10), the part of inclination measurement device (8) four, wherein, guide frame is connected with steel-pipe pile (1) between stake, is filled
Fill out concrete (10) to be located between steel-pipe pile (1) or stake in connection gap, knot is oriented between inclination measurement device (8) and steel-pipe pile (1) or stake
Structure is connected.In the present embodiment, guide frame may be designed as the guider (4) being connected respectively with adjacent stake and guider between stake
(5) two parts, guider (4) and guider (5) can be connected by H profile steel (2) as shown in Figure 1 with steel-pipe pile (1), work as H
, can be using connecting plate (6) as shown in Figure 1 even when shaped steel (2) size is unable to good match with steel-pipe pile (1) and its connector
Connect.In the present embodiment, in order to improve the water-stagnating effect that adjacent staking is stitched, it can be set at adjacent steel-pipe pile (1) seaming position
Water stopping trough (7) as shown in Figure 1 and water sealing structure (9), water sealing structure (9) can be water-swellable body or fill
The sealing bag of water, main purpose is the adjacent staking seam of closure.In the present embodiment, the web (3) of H profile steel (2) and steel-pipe pile (1) it
Between space can also using filling concrete (10) filling.This reality is introduced mainly in conjunction with Fig. 1 in the following part of the present embodiment
With the construction procedure and method of new ultra-deep steel pipe concrete underground continuous structure.The ultra-deep steel pipe concrete construction method of underground continuous wall
Comprise the following steps：The first step, is fixedly mounted leading truck, and the effect of leading truck is mainly first steel-pipe pile (1) of control and applied
Perpendicularity during work, because steel-pipe pile (1) lateral stiffness is big, by controlling the vertical control of steel-pipe pile (1) in work progress
The perpendicularity of steel pipe concrete diaphram wall after the completion of system construction.The first step of the present utility model is completed, into second step.In this step
In rapid, the steel-pipe pile (1) with guider (5) is positioned in leading truck, drill bit is installed in steel-pipe pile (1) bottom so that
Drilling rod is located in steel-pipe pile (1), and installs inclination measurement device (8) in steel-pipe pile (1) side wall, and the diameter of drill bit can compare steel-pipe pile
(1) external diameter is big, and so, after the completion of construction, drill bit can be placed in soil, and a dismounting drilling rod is recycled.Main purpose is so that
The bore diameter got out is more than the diameter of steel-pipe pile (1), is easy to steel-pipe pile (1) to adjust perpendicularity in work progress.Can also
The diameter of drill bit is slightly less than the diameter of steel-pipe pile (1), the brill of larger diameter is got out by drill bit rocking in drilling process
Hole.When the rated capacity of the calibrator (-ter) unit of use is higher, bore diameter can also be made to be less than the external diameter of steel-pipe pile (1), so
Benefit be that need not handle the hole on the outside of pile body after the completion of steel-pipe pile (1) piling construction.Otherwise, needed after pile sinking to steel-pipe pile
(1) space on periphery is handled.The all spaces of stake can be blocked by connecting Grouting Pipe slip casting in the outside of steel-pipe pile (1),
The space on steel-pipe pile (1) periphery can be blocked using the method for high-pressure rotary-spray, it is contemplated that steel-pipe pile (1) belongs to ultra-deep underground structure, can
The drilling rod of high-pressure rotary jet grouting pile or the guiding of drill bit are pre-set in the side wall of steel-pipe pile (1), to prevent rotary churning pile inclined at far-reaching place
From steel-pipe pile (1).So as to complete the second step of the present embodiment, into the 3rd step.In this step, drill bit is driven to bore by drilling rod
Enter the soil body, the soil body of steel-pipe pile (1) bottom is drilled loose or be drilled to mud, steel-pipe pile (1) is sunk into the soil body, steel-pipe pile (1) is sunk to
The casing of drilled pile can be doubled as after the soil body, protects hole wall not cave in, during steel-pipe pile (1) sinks to drilling, is measured simultaneously
The perpendicularity of steel-pipe pile is adjusted, steel-pipe pile (1) is remained vertical, while drilling can be ensured by the constraint of steel-pipe pile (1)
All the time it is vertical, and make drilling all the time with adjacent stake perfect parallelism.The 3rd step is completed, into the 4th step.This step is mainly lasting brill
Hole is to desired depth, while steel-pipe pile (1) is sunk down into expected absolute altitude.After the piling construction of steel-pipe pile (1) is completed, it will can put
Take out and recycle in the drilling rod in steel-pipe pile (1).The 4th step of the present embodiment is completed, into the 5th step.In this step, it will treat
In the guider (5) for the steel-pipe pile (1) that guider (4) insertion on the steel-pipe pile (1) of construction is formerly constructed, and to construct
Steel-pipe pile (1) bottom install drill bit so that drilling rod be located at steel pipe in, and steel-pipe pile (1) side wall install inclinometer pipe, repeat
3rd step to the 4th step, completes the piling construction of next steel-pipe pile (1).In the present embodiment, guider (4) and guider
(5) it can be sub-buckle or box in double buckle, the 5th step of the present embodiment be completed, into the 6th step.In this step, pass through
Whether the perpendicularity that inclination measurement device (8) determines construction steel pile tube (1) meets design requirement, and determine adjacent stake whether jag, such as
Be unsatisfactory for design requirement, then can on pull out steel-pipe pile (1) and construct again, if meeting design requirement, steel-pipe pile, adjacent stake can be connected
The space perfusion concrete at place, and next pile construction can be continued, so as to complete ultra-deep steel pipe concrete diaphram wall of the present utility model
Construction method.In the present embodiment, in the 3rd above-mentioned step, vibratory drilling method or static pressure method can be aided with by steel-pipe pile (1) and its connected
Fitting sinks to the soil body.In addition, in the present embodiment, in the 3rd above-mentioned step, using slotter drill bit can be replaced to complete square
The construction of steel pipe concrete stake diaphram wall.
This patent includes but is not limited to alternative other construction methods used of professional person in the art.
