Description
Technical field
The present invention relates to technical field of buildings, especially underwater concrete secondary intubates stopper.
Background technology
At present, along with expanding economy, capital construction is advanced by leaps and bounds, and underwater cast-in-place pile is widely used in bridge, building basis, macrostructure thing basis etc..But, during filling pile construction, easily there are abnormal conditions in conduit under water, causes having plenty of conduit and cannot normally lower be filled by card, concrete；Having plenty of conduit and occur that under the impact of concrete explosion or conduit connection sealing ring damage, mud enters conduit and is mixed in concrete；Have plenty of owing to manual operation is improper, or control wrong conduit to be proposed concrete surface, cause conduit to enter mud；Have plenty of conduit and imbedded deeply, when pulling out conduit, conduit is put off, cause concrete can not normal construction, need to propose conduit changing, cause conduit secondary to intubate.But, it is to combine with experience to measure that general secondary intubates, and is inserted directly in the concrete poured into by conduit.But because of technological reason, underwater concrete filling pile pile crown contains mud in 02 meters to some extent.When secondary intubates shallower, the concrete with mud having 1-1.5 rice can not be come up by top and stay become stake in stake one；When secondary intubates deeper, being pressed by concrete above, the mud in conduit can not be discharged and stay in stake, becomes a part for stake, and this section of stake, because of poor by its Forming Quality of mud influence, causes this stake B class stake or C class stake occur.The most traditional successful intubation is relatively low and unsecured, broken pile often occurs.And after there is broken pile, the solution generally used: dangerous bigger diving operation, have backfills stake holes, and after parking seven days, circulation drilling machine being replaced with percussive drill is punched out, but the duration is longer；Have increases by two stakes in former pile foundation both sides, solves the stress problem of former stake, but cost is high.Above method not only causes pile foundation construction construction delay, and cost increases therewith.
Summary of the invention
The purpose of the present invention is aiming at the defect that prior art exists, it is provided that a kind of generation avoiding broken pile problem, is effectively guaranteed the finished peg quality of underwater concrete filling pile, and the underwater concrete secondary that improve finished peg A class stake ratio intubates stopper.Its technical scheme is: be provided with first segment conduit on the top of stopper, is provided with stopper shell in the outside of stopper, and the inside medium position at stopper is provided with lock, lock connection is unblanked bracing wire, push rod is located at the lower section of lock, and limiting plate is arranged on the lower section of push rod, and bracing wire connecting stay wire connects ring.Hopper connects first segment conduit, and first segment conduit connects conduit, and limiting plate is divided into casing, is provided with steel reinforcement cage in the lower section of casing, is provided with guy wire support on the right side of limiting plate, is provided with bracing wire spacing B point and bracing wire spacing A point on guy wire support.
Beneficial effects of the present invention: practicality reasonable in design, avoid the generation of broken pile problem, be effectively guaranteed the finished peg quality of underwater concrete filling pile, improve finished peg A class stake ratio, improve product quality and Business Economic Benefit, be suitable for popularity and use.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation that the present invention uses state.
Detailed description of the invention
As shown in Figure 1 and Figure 2, underwater concrete secondary intubates stopper, is mainly connected ring 8, steel reinforcement cage 9, casing 10, conduit 11, limiting plate 12, hopper 13, guy wire support 14, bracing wire spacing B point 15 and bracing wire spacing A point 16 constituted by first segment conduit 1, stopper shell 2, bracing wire 3 of unblanking, lock 4, push rod 5, limiting plate 6, bracing wire 7, bracing wire；It is provided with first segment conduit 1 on the top of stopper, it is provided with stopper shell 2 in the outside of stopper, inside medium position at stopper is provided with lock 4, lock 4 connects bracing wire 3 of unblanking, push rod 5 is located at the lower section of lock 4, limiting plate 6 is arranged on the lower section of push rod 5, and bracing wire 7 connecting stay wire connects ring 8(and sees Fig. 1).Hopper 13 connects first segment conduit 1, first segment conduit 1 connects conduit 11, and limiting plate 12 divides into casing 10, is provided with steel reinforcement cage 9 in the lower section of casing 10, it is provided with guy wire support 14 on the right side of limiting plate 12, guy wire support 14 is provided with bracing wire spacing B point 15 and bracing wire spacing A point 16(is shown in Fig. 2).
Present invention process flow process: measure the end face of underwater concrete with lining rope, the distance between limiting plate on casing.The conduit that will appear from problem proposes in time and is replaced, and is pulled out by the push rod on capping tools and is opened by lock, and first segment conduit end opening inserts in capping tools lock, pushes to push rod to shut lock and conduit is blocked so that it is be in running order.Then, the first segment conduit with capping tools is carried out conventional links with other conduits.Conduit is transferred to top of concrete at about 2.5 meters by the length according to measuring, and adjusts capping tools bracing wire, and bracing wire control cage is fixed on the stopper, checks whether capping tools bracing wire is in free state.Check errorless after, will carry in bracing wire, by A to B, now the push rod on capping tools moves down pull-out drive bracing wire of unblanking and is opened by lock, and capping tools separates with conduit.Vertically measure carrying 20cm-50cm(dip stick on conduit on casing limiting plate), conduit thoroughly departs from capping tools.Promoting bracing wire subsequently to be elevated from concrete by capping tools, secondary underwater concrete intubates successfully, may thereafter continue to carry out the perfusion of concrete.This method thoroughly solves secondary and intubates unsuccessful problem, efficiently solves the broken pile situation caused because conduit goes wrong.
