Description
Technical field
The present invention relates to the dedicated stake field of foundation engineering, cast-in-place pile construction method in specially a kind of discarded ground.
Background technique
Steel mill due to its workshop character of use, foundation all contain deep reinforced concrete foundation, bottom plate,
Level ground and all kinds of pile foundations (prefabricated pile, bored concrete pile etc.), steel-making powerhouse foundation is even also containing Slag Layer, waste steel plate etc., such
It is huge that newly-built pile foundation construction difficulty is carried out on place, it is necessary to could construct after first Ground Treatment.
Summary of the invention
In order to overcome the drawbacks of the prior art, a kind of foundation structure structure quick, that construction is convenient, adaptable of removing obstacles is provided
Part, the invention discloses cast-in-place pile construction methods in a kind of discarded ground.
The present invention reaches goal of the invention by following technical solution:
Cast-in-place pile construction method in a kind of discarded ground, it is characterized in that: successively implementing as follows:
1. summarizing old figure: by factory building foundation plan view, including terrace, basis, pile foundation etc., all summarizing to one first and always put down
On the figure of face, the situation on original underground installation basis in clear workshop place, including basic top surface are drawn on the first general layout
Absolute altitude, buried depth, overall size, pile foundation type, stake is long, the information such as diameter, and the first general layout selects cellophane paper or onionskin,
The graphic color of first general layout is black and white；
Further, can by the first general layout and the second general layout in autoCAD software respectively draw after, then by this
Two figures overlap；
2. summarizing new figure: the newly-built stake bit plan of required construction is summarized to second general layout；
3. overlapping: the first general layout and the second general layout being overlapped, i.e., are inserted in the newly-built stake bit plan of required construction
Factory building foundation plan view marks out the position of new pile in package two general layouts and old basis overlapping；
4. processing: according to the difference of mark situation, it is divided into different treatment measures:
1. 4.: the pile foundation of non-overlapping part is excavated terrace hard formation concrete disintegrating digging machine using pick machine, foundation pit backfill element
It constructs after soil pile foundation；
2. 4.: it is Chong Die with cushion cap foundation, but old pile foundation is encountered, then expose foundation platform after being crushed terrace hard formation concrete, puts
Slope, which is excavated, excavates entire foundation platform, then backfills rammed earth, pile foundation of constructing；
3. 4.: the broken ground hard formation concrete Chong Die with old pile foundation is dug out to cushion cap top, and specific accurate stake position is made in measurement,
The compacting of backfill horsestone, is laid with steel plate, pulls out old stake after installing pile pulling mechanical equipment all casing drill, old stake backfills element after pulling out
Soil pressure is real, is irrigated pile driving construction using long casing；
4. 4.: stake machine is in place, drills, installs steel reinforcement cage, installation conduit, casting concrete etc..
Cast-in-place pile construction method in the discarded ground, it is characterized in that: step 1. with step 2. when, the first general layout
On graphic color and the second general layout on graphic color select different colors to draw.
Cast-in-place pile construction method in the discarded ground, it is characterized in that: step 4. -3. when, filling pile construction steel shield
Tube length degree is not less than the depth for backfill of removing obstacles, and steel pile casting length is not less than 3 meters.
The invention has the following beneficial effects: solve the problems, such as filling pile construction in the old factory site base such as steel mill, Ke Yiyou
It targetedly removes obstacles, accelerates pile foundation construction progress, reduce construction cost and accelerate progress, be suitable for old the reconstruction of steel mill or again
Utilize the infrastructure in discarded steel mill.
Detailed description of the invention
Fig. 1 is flow chart of the invention.
Specific embodiment
The present invention is further illustrated below by way of specific embodiment.
Embodiment 1
Cast-in-place pile construction method in a kind of discarded ground is successively implemented as follows as shown in Figure 1::
1. summarizing old figure: by factory building foundation plan view, including terrace, basis, pile foundation etc., all summarizing to one first and always put down
On the figure of face, the situation on original underground installation basis in clear workshop place, including basic top surface are drawn on the first general layout
Absolute altitude, buried depth, overall size, pile foundation type, stake is long, the information such as diameter, and the first general layout selects cellophane paper or onionskin,
The graphic color of first general layout is black and white；
Further, can by the first general layout and the second general layout in autoCAD software respectively draw after, then by this
Two figures overlap；
2. summarizing new figure: the newly-built stake bit plan of required construction is summarized to second general layout；
The graphic color in graphic color and the second general layout on first general layout selects different colors to draw, generally
The figure on ground, the first general layout selects black to draw, and the figure of the second general layout selects red or other colored colors
It draws；The color of complementary color each other can also be selected with the graphic color in the graphic color and the second general layout on the first general layout
Colored drawing system, so that the figure color contrast on two general layouts is larger；
3. overlapping: paper is inserted in old foundation plan
First general layout and the second general layout are overlapped, i.e., the newly-built stake bit plan of required construction is inserted in factory building foundation
Plan view, by new pile (generally i.e. chrominance section) in package two general layouts and old basis (generally i.e. black and white part) overlapping
Position mark out；
4. processing: according to the difference of mark situation, it is divided into different treatment measures:
1. 4.: the pile foundation of non-overlapping part is excavated terrace hard formation concrete disintegrating digging machine using pick machine, foundation pit backfill element
It constructs after soil pile foundation；
2. 4.: it is Chong Die with cushion cap foundation, but old pile foundation is encountered, then expose foundation platform after being crushed terrace hard formation concrete, puts
Slope, which is excavated, excavates entire foundation platform, then backfills rammed earth, pile foundation of constructing；
3. 4.: the broken ground hard formation concrete Chong Die with old pile foundation is dug out to cushion cap top, and specific accurate stake position is made in measurement,
The compacting of backfill horsestone, is laid with steel plate, pulls out old stake after installing pile pulling mechanical equipment all casing drill, old stake backfills element after pulling out
Soil pressure is real, is irrigated pile driving construction using long casing, and the steel pile casting length of filling pile construction is not less than the depth for backfill of removing obstacles,
And steel pile casting length is not less than 3 meters；
4. 4.: stake machine is in place, drills, installs steel reinforcement cage, installation conduit, casting concrete etc..
