Technical field
The present invention relates to building operations, be specifically related to gas lift reverse circulation mud circulating system.
Background technology
Current, the construction of Longspan Bridge is more and more.The basis of Longspan Bridge adopts drilled pile mostly, and it is large that such drilled pile has diameter, and the degree of depth is dark, enters the dark feature of rock.This type of drilled pile generally adopts gas lift reverse circulation mud circulating system to construct, and gas lift reverse circulation mud circulating system comprises the gas lift reverse circulation hydraulic power head rig of holing, and mud separator, mud pit and mud circulation pipeline.
Mud circulation pipeline comprises: mend slurry pipe, return pipe and residue outlet.Wherein, mend slurry pipe for supplementing the loss of boring procedure mud, mud pit slurry transportation, to steel casing, is guaranteed in casing, mud face absolute altitude meets code requirement; Return pipe, for the slag depositing cylinder mud crossed separated with mud separator is back in casing, guarantees the cycling and reutilization of mud; Residue outlet, is then flowed into and in mud separator, is carried out separation by sebific duct to slag depositing cylinder for the slurry transportation with boring mud that drilling rod " suction " is gone out.
In current work progress, the benefit of mud circulating system slurry pipe, return pipe and residue outlet are sebific duct, and equipment is above platform.Residue outlet adopts sebific duct directly to connect drilling rod and the mud separation equipment of rig; Overfall sebific duct connects mud separation equipment and executes boring, by the slurry transportation after separation to hole; Mending slurry sebific duct is directly connected to and is executed boring by mud pit on mud pit or ship on the bank.Like this, significantly reduce in the space that utilizes of platform, and the inconvenience of having given the movement of equipment and operating personnel's routine work band; During each mobile drill, mending slurry pipe, return pipe and three pipelines of residue outlet all needs mobile; When sebific duct moves, need adopt loop wheel machine to coordinate, increase the workload of loop wheel machine; Sebific duct is spillage often, cause mud through platform flow to rivers, platform and surrounding enviroment have been produced to great pollution, and constructor's personal safety have been caused to threat.
Summary of the invention
Technical problem to be solved by this invention is to solve gas lift reverse circulation mud circulating system operation inconvenience, and the usage space of platform is little, and loop wheel machine workload is large, the problem that construction operation environment is poor.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is to provide a kind of gas lift reverse circulation mud circulating system, comprise operation platform, rig, mud pit, mud separation equipment and mud circulation pipeline, described rig is arranged on described operation platform, described mud circulation pipeline comprises residue outlet and the return pipe that is separately positioned on both sides, position, every row hole drilling stake hole, described residue outlet and return pipe are separately fixed on the platform girder below described operation platform and with described mud pit and corresponding mud separation equipment and form circulation line, described residue outlet with on return pipe, be respectively equipped with slag tap tee piece and the overfall tee piece corresponding with the position, hole of respective bore stake, the 3rd outlet of the described tee piece of slagging tap is stretched out vertically upward described operation platform and is connected with the sebific duct of slagging tap of described rig by flange, the 3rd outlet along continuous straight runs of described overfall tee piece is communicated with the steel casing inner chamber of respective bore stake.
In such scheme, described mud circulation pipeline also comprises two-way benefit slurry pipe, be arranged in both sides, operation platform top, and the tee piece with valve is all set, with the increase of executing borehole drilling hole depth, utilize sebific duct to supplement mud to guarantee that in steel casing, mud face absolute altitude meets code requirement to executing in boring, two-way is mended slurry Guan Jun and is extended to by mud pit, forms mud circulation closed-loop path with mud pit.
In such scheme, described mud pit is divided into four separations, is followed successively by the first overfall pond, the second overfall pond, pulp storage tank and slurrying pond, and between described the first overfall pond, the second overfall pond and pulp storage tank, the overfall by is separately communicated with successively respectively.
In such scheme, described mud separation equipment comprises many group sediment buckets and mud separator, and described residue outlet one end adopts 90 degree elbows protrude upward operation platform and be connected with the slag input sebific duct of described sediment bucket by flange, and the other end adopts flange sealing.
In such scheme, described return pipe one end adopts the 90 degree elbows with overfall current collector to protrude upward operation platform, the end face outlet of described overfall current collector is connected with the pulp sebific duct of described sediment bucket by flange, side exit is connected with described mud separator pulp sebific duct by flange, and the other end of described return pipe adopts flange sealing.
The present invention, because mud circulation pipeline is arranged on the platform girder of operation platform below, therefore, tool has the following advantages:
It is mobile that residue outlet and return pipe do not need: before drilling-machine shifter, rig sebific duct and the platform tee piece adpting flange of slagging tap of slagging tap is opened, the sebific duct of slagging tap is removed in the lump with rig; After rig is in place, rig sebific duct and the platform tee piece adpting flange of slagging tap of slagging tap is communicated with.After rig is in place, only casing overfall mouth to be onstructed need be opened, with other casing overfall mouth shutoff of row.Like this, remove traditional mobile residue outlet and the trouble of return pipe from, greatly reduced the workload of loop wheel machine.And residue outlet and return pipe are all under platform, do not take operating space on platform, make utilized space on platform greatly increase and increase the safety of constructor's operation on platform.When residue outlet or return pipe obstruction, outlet(discharge) flange can be opened, in other end, adopt high pressure water washing, guarantee the unobstructed of residue outlet.
In sum, the present invention has improved the utilization rate of platform upper space; It is neat reasonable to make to arrange on platform, has reduced potential safety hazard; Avoided the pollution of mud to surrounding enviroment; Improved the cyclic utilization rate of mud; Simplify the operation that rig moves hole, improved operating efficiency; Reduced the dependence to loop wheel machine in boring procedure.
