Abstract
The utility model is related to a kind of sealing guiding valve used during bored pile underwater concrete pouring construction, specially water proof plug.Water proof plug, including main body, ring flat-plate and L-type rubber ring, the main body are made up of steel plate, and L-type rubber ring is installed between main body and ring flat-plate, and main body, L-type rubber ring are fixedly connected by blending bolt with ring flat-plate.Body thickness is 3~5mm, and diameter is less than 2~3cm of tremie internal diameter.Several supporting leg steel bars are welded with ring flat-plate, are integrally conical after having welded.L-type rubber ring external diameter is slightly larger than tremie internal diameter to ensure the seal of water proof plug.During water proof plug declines, the bullet formed by supporting leg steel bar plays a part of keeping water proof plug ring plate vertical with tremie inwall, can separated concrete and water body (mud), the water proof plug fallen into hole will be left in pile concrete.Because it is made up of steel substantially, its intensity can ensure that it will not have a negative impact to pile quality.
Description
Technical field
The utility model is related to a kind of sealing guiding valve used during bored pile underwater concrete pouring construction, is specially
Water proof plug.
Background technology
In existing bored concrete pile industry, underwater gliders occupy very big proportion always, and coagulation under water
Soil work progress in, except parameters such as concrete mix, water content and the slumps outside, how to avoid first set concrete from passing through
It is the most important thing for ensureing pile quality that conduit, which enters, situations such as cause to isolate after water (or mud), break up.
According to existing professional standard《Technical code for building pile foundation》JGJ79-2008, when underwater concrete first set is poured,
Funnel bottom, using bladders or the water proof bolt being fabricated to by pea gravel concreten, is to ask first set concrete with water proof bolt in Action of Gravity Field
Pass through tremie access aperture bottom down.And according to construction practical experience, bladders go out after conduit easily by steel reinforcement cage clamp without
It can float, pile quality is had a strong impact in pile body formation bubble；On the one hand precast concrete test specimen wastes time and energy, it is necessary to according to leading
The size field of pipe is made, maintenance, and on the other hand it can not be deformed to catheter requirements, perpendicularity will get well, and even so, still sent out
Raw test specimen obstruction conduit phenomenon.
Utility model content
The utility model researches and develops a kind of new water proof plug and avoids above skill to solve existing bladders, the shortcoming of water proof bolt
The various shortcomings of art.
The technical solution of the utility model is as follows：Water proof plug, including main body, ring flat-plate and L-type rubber ring, the main body are steel
Plate is made, and L-type rubber ring is installed between main body and ring flat-plate, and main body, L-type rubber ring are fixedly connected by blending bolt with ring flat-plate.
Further, the body thickness is 3~5mm, and diameter is less than 2~3cm of tremie internal diameter.
Further, the ring flat-plate is made up of steel, and several supporting leg steel bars are welded with ring flat-plate, and supporting leg steel bar has bullet
Property.The supporting leg steel bar is integrally conical after having welded.
Further, the L-type rubber ring external diameter is slightly larger than tremie internal diameter to ensure the seal of water proof plug.
The operation principle of the water proof plug is：Complete after decentralization conduit, before perfusion first set concrete, water proof plug is positioned over
Funnel bottom, supporting leg steel bar is upward.During water proof plug and first set concrete drop under gravity, formed by supporting leg steel bar
Bullet, plays a part of keeping water proof plug ring plate vertical with tremie inwall, until concrete and water proof plug are filled in the lump
Enter in water body in hole (mud), water proof plug can separate concrete and water body (mud) in the process, the water proof fallen into hole
Plug will be left in pile concrete, because it is made up of steel substantially, and it is unfavorable that its intensity can ensure that it will not be produced to pile quality
Influence.
The water proof plug is effectively solved during filling pile construction, underwater grouting first set concrete and bottom water body (mud)
Isolation problem.Compared with bladders, water proof plug, which is fallen into pile concrete, to have a negative impact to pile quality.With it is prefabricated
Concrete sample is compared, and water proof plug cost is lower, can be mass, and applicability is stronger, and is difficult plugging, utilizes efficiency of construction
Lifting.

Embodiment
With reference to specific embodiment and Figure of description, the utility model is described in further detail.Tool described herein
Body embodiment only to explain the utility model, is not used to limit the utility model.
Embodiment：As shown in Figure 1, Figure 2, Figure 3 shows, water proof plug, is made up of main body 1, ring flat-plate 2 and L-type rubber ring 3.Main body 1,
Ring flat-plate 2 is made of steel, and the wherein one side of ring flat-plate 2 welds 10 supporting leg steel bars.L-type rubber ring 3 is installed, so on ring flat-plate 2
Main body 1 is buckled on L-type rubber ring 3 afterwards, L-type rubber ring 3 is clipped in the middle, blending bolt is by main body 1, L-type rubber ring 3 and ring
Plate 2 is integrally fixed.
The body thickness is 3~5mm, and diameter is less than tremie 2~3cm of internal diameter, can be put into conduit.Ring flat-plate
10 supporting leg steel bars of upper welding, it is flexible, it is integrally conical, is put into after conduit after having welded, holding water proof plug can be played
The ring flat-plate effect vertical with pipe inner wall.L-type rubber ring external diameter is slightly larger than tremie internal diameter to ensure the closed of water proof plug
Property.
Water proof plug is solved during filling pile construction, the isolation of underwater grouting first set concrete and bottom water body (mud)
Problem, it is ensured that the construction quality of bored concrete pile, its main body is made up of steel, its intensity can ensure that it will not be produced not to pile quality
Profit influence.This product is readily put into mass production, and production cost is low, strong applicability, with wide market prospects.
It is the utility model preferred embodiment in summary, all changes made according to technical solutions of the utility model, institute
The function of production without departing from technical solutions of the utility model scope when belong to protection domain of the present utility model.
