Description
Technical field
The present invention relates to a kind of construction equipment of on-water bridge, specifically, relate to a kind of sealing water device for realizing that the waterless operation environment is adopted when utilizing the concrete casing to carry out the on-water bridge bearing platform construction.
Background technology
At present, highrise pile cap uses traditional steel box method substantially under water both at home and abroad, utilizes the steel box to provide water-less environment for bearing platform construction, so that carry out follow-up bearing platform construction.Yet there are many deficiencies in this kind method, at first the construction period long, workload is big, a task difficulty height, and will cause highly, material usage is many; In addition, there is repeatedly construction, thereby makes the risk that absolute altitude is raised at the bottom of the cushion cap.At these deficiencies, patent " water-bed no-bottom closing concrete boxed cofferdam and application process thereof " formerly, in the number of patent application 200710113358.5, proposed a kind of concrete casing that utilizes and carried out the new of bearing platform construction, the application for the concrete casing in this job practices has reached ultimate attainment, and casing need not to remove, directly become the part of cushion cap, make construction cost reduce greatly, construction period shortens greatly, has bigger using value.Of paramount importance operation in the related construction technology of this patent application, the operation that can be described as core are exactly the operation of the inner sealing of casing, if can not address this problem, the casing of so this no back cover just provides an anhydrous construction environment at all, and remaining step also all just can't be implemented.In this patent application, the water-stopping method that is adopted is exactly a plurality of sealing capsule inflations default at the bottom of the casing case, thereby reach the effect of sealing, as if theoretically, this method does not have problems, but in fact but also have certain hidden danger, at first, this capsule is an air filling type capsule, and the capsule of air filling type can be subjected to buoyancy of water and constantly float in practical operation, thereby can't reach the effect of sealing; Secondly, because the volume of air bag is bigger, need to finish at short notice the water shutoff operation again, therefore inflation makes the air pressure requirement very high, and this just requires very high to the tautness with valve and rubber joint portion, be very easy to occur the phenomenon that valve is torn, because bearing platform construction need cooperate the time of morning and evening tides, and the coordinating operation of multiplex's kind, in a single day, will cause the lot of manpower and material resources loss so these problems occur.
Summary of the invention
The present invention is directed to existing does not have the stagnant water effect weak effect that exists in the back cover concrete casing working procedure, the deficiency that is prone to construction accident under water, and a kind of back cover concrete casing employed water shutoff capsule of constructing that do not have under water is provided.
Technical scheme of the present invention is: a kind of do not have back cover concrete casing construction water shutoff capsule under water, described water shutoff capsule is placed in the concrete cover box plate preformed hole water shutoff capsule preformed groove on every side, the water shutoff capsule is a rubber-tyred tubular capsule, not during water-filling for flat stacked, the cross section is rectangular, a water inlet tap is set on the water shutoff capsule, and this water inlet tap exposes to the water shutoff capsule and reserves outside the reserved opening in storehouse;
Preferably, described water inlet tap comprises logical pedestal in the water inlet pipe of a L type, the inverted T-shaped and is sleeved on compressing tablet and clamp nut on the pedestal from the bottom to top successively, the end of L type water inlet pipe is connected by internal and external threads with the top of inverted T-shaped pedestal, the rubber capsule is pressed together between pedestal and the compressing tablet, and mutually bonding with pedestal and compressing tablet by adhesive;
Preferably, the end of the water inlet pipe of described L type is three layers of frustum cone structure that radius dwindles successively, in the inside inner chamber of logical pedestal be provided with a brace table that matches with the water inlet pipe end, water inlet pipe middle level round platform with in rubber gasket is installed in the cavity that forms of logical pedestal;
Preferably, the top of described water inlet pipe is equipped with the connector that matches with high-pressure hydraulic pump;
Preferably, the soffit of the upper surface of described inverted T-shaped pedestal shoulder and compressing tablet is provided with the cannelure or the raised annular bar of depression;
Preferably, the allocation ratio of the utricule of described water shutoff capsule is natural rubber 65-72 part, butadiene-styrene rubber 28-34 part, activating agent 5-10 part, age resistor 1.5-4 part, softening agent 6-8 part, carbon black 32-35 part, accelerator 1-3 part, vulcanizing agent 1.5-2 part.
Beneficial effect of the present invention is: at first, this water shutoff capsule is the capsule that a kind of water-filling is used, and is water owing to what charge in the capsule, so the problem of the existing existing come-up of air filling type capsule can never occur; Secondly, in order to adapt to the water-filling operation, therefore specially cooperate and go up special-purpose charging connector structure, and adopted special combination for the joint portion of valve and capsule, therefore can adapt to the high-pressure flush operation, defective such as not tear, guarantee normally carrying out of construction and air bag can not occur.
