Abstract
The utility model belongs to the technical field of underwater concreting construction, and particularly discloses a movable conduit end plug for underwater concreting, which solves the problems of longer time consumption for conduit insertion for pumping in consequent working procedure during large-area underwater concreting, and influence on concrete compactness. The movable conduit end plug for underwater concreting comprises a steel pipe capable of being inserted into a conduit, the outer diameter of the steel pipe is consistent with the inner diameter of the conduit, an S clip for fixing the steel pipe is arranged on the upper portion of the inner wall of the steel pipe, a plug steel plate capable of thoroughly covering a conduit end is arranged at the lower end of the steel pipe, a hook is arranged on the plug steel plate, and an anti-drag conical head is arranged on the lower portion of the plug steel plate. The movable conduit end plug for underwater concreting has the advantages that the movable conduit end plug is simple in manufacturing and convenient in construction, simplifies conduit insertion procedure during underwater concreting, saves operation time, and improves efficiency. In addition, the conduit in a full-sealed structure eliminates influence of underwater sediment and accumulated water in the conduit on concrete compactness, and guarantees construction quality.
Description
Technical field
The utility model belongs to the technical field of Placement of Underwater Concrete for Casting, is specifically related to a kind of catheter end head movable drain plug that is used for the underwater concrete perfusion.
Background technology
Placement of Underwater Concrete for Casting adopts tremie method usually, present catheterized reperfusion is directly conduit to be inserted under water, catheter end head does not add other device, during the head concrete placing, adorn a ball of being close to tube wall at the conduit top, penetration concrete extrudes ball along pipe then, promptly finishes first concrete placing.When large tracts of land was built many conduits of underwater concrete layout, ponding needed to extract out with submersible pump in the follow-up conduit, could begin the perfusion of underwater concrete.Increased the submersible pump operation of drawing water like this, the underwater concreting time is longer; And easily the mud sediment is brought into when further conduit is inserted concrete in the concrete and influenced concrete density; Ponding in the conduit is difficult to pump, and forms interlayer easily, influences the density of underwater concrete.
Summary of the invention
Follow-up insertion conduit drew water the operation time spent than length and to the influential problem of concrete density when the utility model was built underwater concrete in order to solve large tracts of land, and a kind of catheter end head movable drain plug that is used for the underwater concrete perfusion is provided.
The utility model adopts following technical scheme to realize:
The catheter end head movable drain plug that is used for the underwater concrete perfusion, it is characterized in that it comprises the steel pipe that can insert in the conduit, the steel pipe external diameter is consistent with the conduit interior diameter, the steel pipe upper inside wall is provided with the S card that fixing steel pipe is used, the steel pipe lower end is provided with the plug steel plate that can comprehensively cover catheter end head, the plug steel plate is provided with suspension hook, and plug steel plate bottom is provided with the drag reduction conehead.
The steel pipe upper inside wall is symmetrical arranged 6 S cards.The plug steel plate is circular, and plug steel plate diameter is than the big 10cm of conduit diameter.The drag reduction conehead is that drift angle is 60 ° a four sides cone, and the diagonal angle line length of the top cross section of four sides cone is consistent with the conduit external diameter.
Movable drain plug dropped when the utility model S card prevented that conduit from transferring; The plug steel plate is when concrete spouting, the plug steel plate of one side conduit periphery and concrete contact surface have reduced plug and have washed speed open, make the outer concrete of conduit increase a downward active force when carrying conduit on the other hand, be convenient to washing open of drag reduction conehead to plug; Resistance when the drag reduction conehead can reduce conduit insertion concrete; Connect on the suspension hook and can in time it be left the water after seizing wire is convenient to plug and is washed open.
The utlity model has following beneficial effect: make simply easy construction; The intubate operation has been saved the activity duration when having simplified the underwater concrete perfusion, has improved efficient; Conduit is all-sealed structure, eliminated that ponding has guaranteed construction quality to the influence of concrete density in the sediment and conduit under water.

Among the figure: 1-elephant trunk, 2-deck roof, 3-conduit, the 4-seizing wire, 5-conduit counterweight, 6-drag reduction conehead, the first concrete placing of 7-, the 8-steel pipe, 9-plug steel plate, 10-S card, the 11-suspension hook, the diagonal angle line length of the top cross section of L-four sides cone, d-conduit external diameter, D-plug steel plate diameter.
The specific embodiment
In conjunction with the accompanying drawings the specific embodiment of the present utility model is described further.
With certain bridge steel cofferdam bottom concrete construction is example:
Adopt the conventional first concrete placing of ball that once pulls out, when the concrete spouting height reaches 0.8m ~ 1.0m, φ 300mm conduit is with movable drain plug sealing and counterweight is set, and inserts after movable drain plug and conduit junction snarl with wide adhesive tape in the concrete placing, continues concrete perfusion then.Concrete enters conduit from the elephant trunk of conduit top, because concrete pressure is washed plug open, slowly promotes then and mobile conduit, realizes the concrete continuous perfusion.
Concrete steps:
1), movable drain plug design: movable drain plug comprises the steel pipe 8 that can insert in the conduit 3, fixing S card 10, plug steel plate 9, drag reduction conehead 6, the suspension hook 11 used of steel pipe.Wherein, steel pipe 8 long 5cm, external diameter is consistent with conduit 3 internal diameters; Be symmetrical arranged the S card 10 of 6 φ 10mm reinforcement fabrications on steel pipe 8 inwalls; Below steel pipe 8, establish the plug steel plate 9 of diameter than the big 10cm of conduit 3 external diameters; Establishing drift angle below the plug steel plate 9 is the drag reduction conehead 6 of 60 ° four sides cone, and its diagonal angle line length is consistent with conduit external diameter diameter;
2), to calculate the counterweight gross weight be 1400kg, divides six groups to be installed on the conduit, counterweight adopts steel discarded on the building site;
3), be positioned over assigned address after all conduits are all loaded onto counterweight, refill movable drain plug when treating downcomer;
4), movable drain plug is installed;
5), conduit mouth twines with marine glue, guarantees sealing;
6), fixedly connected with suspension hook 11 with φ 4mm seizing wire 4, one section is exposed deck roof;
7), after conduit inserts assigned address, check in the conduit whether intake, can concrete placing after determining not intake with low-pressure lamp;
8), when concrete pours into conduit, conduit is mentioned 20cm so that the S card of plug and conduit break away from, concrete is flowed out from conduit, utilize seizing wire that plug is left the water simultaneously.
