Description
Technical field
The present invention relates to pumping concrete construction field, particularly a kind of be located in pump line system can the equipment of easy cleaning the reinforcement of concrete and using method thereof.
Background technology
Pumping concrete construction process generally refers to by High pressure cement pump and pump line system, good for mobility concrete conveyance is carried out the work progress of concreting to appointed area.This work progress is often applied to the concrete pouring construction in Civil Engineering Construction.High pressure cement pump common in construction is divided into two classes: automotive pump and drag pump.Concrete in this work progress generally adopts the commercial concrete of concrete mixing plant mixing in advance.Commodity coagulation delivers to job site by concrete mixer after mixing in advance, and then concrete is transfused in High pressure cement pump and carries out operation.Described pump line system is made up of the single-unit pump line of certain length, generally often saves 2 ~ 3m, saves and generally adopt Flange joint (buckle sometimes also can be adopted to be connected, but the pressure that Flange joint can bear connecting higher than buckle) between joint.Pumping concrete construction is used to be conducive to improving efficiency of construction, convenient construction.
The work progress of conventional pumping of concrete is as follows: 1, at the construction field (site) near location arrangements High pressure cement pump of vehicle in and out port; 2, pump line of arranging moves towards and connects pump line, forms pump line system; 3, commercial concrete is delivered to job site, carry out pumping of concrete operation.
After the construction operation of pumping of concrete completes, the concrete cleanup step of High pressure cement pump and pump line system is as follows: 1, concrete pump is shut down; 2, remove the joint pump line near concrete pump, form two outlets (concrete pump is led in an outlet, and another leads to pump line system); 3, cleaning concrete pump, by waste water by exporting discharge; 4, fill in a sponge ball at the end of pump line system and connect an air pump, starting small air pump, the concrete that sponge ball is promoted in pump line refluxes, and discharges from outlet.
High pressure cement pump and pump line system have some problem following when clearing up concrete: 1, because the pump line in pump line system is by Flange joint, therefore dismantle pump line (removing the bolt on flange) and need the long period, but concrete can not stop for a long time in pump line, this is because long-term immobilising concrete can solidify and block pump line, block pump line be difficult to cleaning and time-consuming, so when clearing up pump line, the time of removing pump line is very limited, requires constructor many and constructs skilled; 2, from the view of security, owing to there is concrete in pump line system, if the scope of operation is higher than outlet (the such as scope of operation is at certain floor), because Action of Gravity Field concrete is at outlet mineralization pressure, potential threat is caused to constructor; The concrete of the discharge 3, after cleaning cannot recycle, and form discarded object, operations number is more, and pump line system is longer, and discarded object is more.
Summary of the invention
The object of this invention is to provide a kind of pumping of concrete cleaning current divider and using method thereof, solve traditional pumping of concrete manner of cleaning up time-consuming, easily cause pump line to block, potential threat and the too many technical problem of discarded object (discarded concrete) can be caused to constructor.
For achieving the above object, the present invention adopts following technical scheme: a kind of pumping of concrete cleaning current divider, on pump line disposed in the outdoor, is characterized in that: comprise cleaning current divider body A, cleaning current divider body B and knife gate valve.
One end of described cleaning current divider body A is provided with the circular flange A be connected with outdoor pump line, the other end of cleaning current divider body A is connected with the end flange of bolt with cleaning current divider body B by square flange, flange cushion block, and the other end of cleaning current divider body B is provided with the circular flange B be connected with outdoor pump line.
The tube wall that the tube wall of described cleaning current divider body A is provided with current divider outlet A, described cleaning current divider body B is provided with current divider outlet B, and described current divider outlet A and current divider outlet B is equipped with outlet capping.
Described knife gate valve is made up of knife gate valve valve plate and the knife gate valve hammering handle being positioned at knife gate valve valve plate two ends, and knife gate valve valve plate has the disconnecting link valve opening that a diameter is less than cleaning current divider internal diameter of tube body, described knife gate valve valve plate is clipped between cleaning current divider body A and cleaning current divider body B, square flange and flange cushion block surround in space.
Described outlet capping and current divider export between A, export capping and current divider exports between B and all can accompany rubber ring.
Described outlet capping and current divider export between A, export capping and current divider exports and all can be buckle between B and be connected.
On outdoor pump line above the fertile groove that described pumping of concrete cleaning current divider can be located at job site.
A using method for pumping of concrete cleaning current divider, is characterized in that step is as follows: step one, High pressure cement pump are shut down; Step 2, hammering knife gate valve hammering handle, until knife gate valve valve plate closes the supervisor of pumping of concrete cleaning current divider completely; Step 3, fill in sponge ball at pump line system end, and connect an indoor air pump; Outlet capping on step 4, removal current divider outlet A and on current divider outlet B; Step 5, start indoor air pump, the concrete in pump line exports B by current divider and flows out under the promotion of sponge ball, then enters fertile groove; Step 6, start High pressure cement pump, concrete remaining in pump and water for cleaning divide and export A by current divider and flow out, and then enter fertile groove.
Compared with prior art the present invention has following characteristics and beneficial effect: the present invention is applied to the pumping concrete construction in building operations, can solve time-consuming, the easy pump line of the manner of cleaning up occurred in pumping of concrete scale removal process and block, can cause potential threat to constructor and the adverse effect such as discarded object is too many.
Carry out concrete prune job by the present invention, the efficiency of construction in the unit interval can be made to be improved.Specifically, utilize the knife gate valve in the present invention to control concrete flow direction exactly, clean-up phase can be entered (without the need to dismantling pump line fast from pumping stages, the less manpower so the ratio bolt removed on flange more saves time), therefore the probability that concrete solidifies in pump line is greatly reduced, reduce the risk that pump line blocks, also improve the safety guarantee of constructor simultaneously greatly.
After employing the present invention, the discarded object (discarded concrete) that cleaning is discharged directly can enter fertile groove (discarded object is filled in fertile groove and belongs to rational utilization), so avoid rehandling, decrease the discharge of discarded object, decrease corresponding environment pollution.
