Description

A kind of quick positioning construction method of steel pipe column-stake
Technical field
The present invention relates to when underground engineering is bright do time need the barrier such as highway crossing, building and the engineering construction side that takes Method, is specifically related to a kind of quick positioning construction method of steel pipe column-stake.
Background technology
Cap excavation method be when underground engineering is bright do time need the barrier such as highway crossing, building and the Novel engineering construction taked Method, be faced down by ground and be excavated to certain depth after, by top seal, remaining bottom engineering is carried out under the top cover closed Construction.Agent structure can be along making, it is also possible to inverse work.
In recent years, along with the fast development of China's infrastructure construction, in track traffic and high-rise Construction of Basement, adopt Dig, with lid, the engineering that Counter procedure builds to get more and more.
Sheltered reverse excavation has many good qualities, and there is also a lot of difficult point.Such as erection of steel pipe column perpendicularity, setting accuracy are wanted Asking high, construction depth is big, and in China's contrary sequence method station and hypogee, the installation of steel pipe column uses two kinds of construction methods mostly: (1) manually abolish pile crown installation positioner after burying steel thimble underground and fix steel pipe column;(2) HPE hydraulic tools are used to be inserted perpendicularly into steel Tubing string.It is long to there is the construction period in the first Traditional Man broken pile head installation positioner positioning steel tube post method, complex procedures, construction peace The shortcoming that full blast danger is big, the second HPE hydraulic tools are inserted perpendicularly into steel pipe column positioning mode and there is (hydraulic pressure high to construction site requirement Need to harden leveling in device bottom basis), the shortcoming that construction cost is big.
Summary of the invention
The goal of the invention of the present invention is that a kind of quick positioning construction method of steel pipe column-stake of offer, construction party of the present invention Method has compared with above two engineering method: steel pipe column setting accuracy is high, good integrity, and the duration is short, security risk is low, construction The features such as low cost.
The technical scheme is that
One steel pipe column of the present invention-quick positioning construction method of stake, its method step is:
(1) it is first according to process sequence carry out measure of pile position → drilled pile pore-forming → steel reinforcement cage and transfer to aperture → lifting steel The work of tubing string, during for preventing from pouring drilled pile concrete, steel pipe column floats, and must use 4~6mm thickness steel before steel pipe column lifts Plate is setting height soldering and sealing plugging plate bottom steel pipe column and above bottom, and position pours design between steel pipe column two plugging plate The slightly expanded concrete of the number of being calibrated vibration compacting, on concrete, interface plugging plate centre adhesive band crosshair is reflective Patch.
(2) joint steel pipe post and steel reinforcement cage, 4 hydraulic jack bottom steel pipe column are installed
Hanging drilled pile reinforcing cage suitable for reading to ground, lifting steel pipe column is connected with steel reinforcement cage, 90 ° of directions bottom steel pipe column Installing four hydraulic jack, jack is placed on above the steel plate welded with steel pipe column, and jack head stress surface is steel pipe Post sidewall, root stress surface is steel pile casting side at steel reinforcement cage, and steel pile casting length is about 1.2~1.7m, outside internal diameter is with steel reinforcement cage Footpath is identical, and steel pile casting uses with steel reinforcement cage and is welded to connect.
(3) lifting steel pipe column and steel reinforcement cage, fix upper steel tubing string according to design attitude.
After connecting steel pipe column and steel reinforcement cage and having debugged hydraulic jack, lifting steel pipe column is to designed elevation, steel pipe column Four hand jacks are installed in direction, 90 °, upper end, use hand jack to adjust plan-position, steel pipe column upper end to the position designed Postpone fixing.
(4) suspention sash weight, adjusts steel pipe column bottom position
Use at steel pipe column mouth and hang cross hairs alignment position, at the bottom of center suitable for reading suspention plumb bob positioning steel tube post Center, portion, makes reflection plaster cross searching match with plumb bob tip by adjusting four hydraulic jack bottom steel pipe column, Hydraulic jack is used to fix after being adjusted to design attitude bottom steel pipe column.When adjusting steel pipe column bottom position by bright light torch Irradiate reflection plaster, adopt the position relationship between the plumb bob of telescopic observation suspention hammer and reflection plaster cross searching.
(5) drilled pile concrete is poured
Through check steel pipe column plan-position and absolute altitude errorless after, outside steel pipe column install concreting conduit, be anti- Only card pipe phenomenon is transferred and existed in lifting process to conduit, welds three catheter directed reinforcing bars, conduit in advance in steel pipe column side Along guiding reinforcement location installation in installation process;For preventing the foreign material such as mud, rubble in concreting process from entering steel pipe column In, steel plate flange closure is used at steel pipe column top.Concreting checks steel pipe column plane position after bottom steel pipe column again Putting and absolute altitude, confirmed plan-position and absolute altitude continue casting concrete to designed elevation after meeting design specification.
(6) steel pipe column interior concrete is poured
After drilled pile concreting completes, extract and conduit be installed after conduit water is rinsed well again in steel pipe column, Pour steel pipe column interior concrete.
(7) backfill steel pipe column peripheral space
For ensureing to close on drilled pile construction safety, after pile concrete intensity hole to be drilled reaches design strength, use sand material Backfill steel pipe column peripheral space.
The invention have the benefit that
The inventive point summary of the present invention is just utilized in 90 ° of directions bottom steel pipe column and installs 4 hydraulic jack, steel pipe columns Direction, 90 ° of top is installed 4 hand jacks and is fixed steel pipe column, utilizes bottom steel pipe column suspention suitable for reading plumb bob alignment steel pipe column anti- Positioning mode in light patch cross searching point tune, steel pipe column completes with pile concrete primary concreting.With aforementioned two kinds of construction parties Method compares, and the inventive method has: steel pipe column setting accuracy is high, good integrity, and the duration is short, security risk is low, be constructed into The advantages such as this is low.The inventive method has been put to use in Practical Project is constructed, the effect of each unit in charge of construction reflection present invention The best, not only construction cost is low, and speed of application is fast, location is the most accurate, and during construction, workman represents that safety is the highest, More than existing build engineering time the lid that uses to dig Counter procedure strong.
