Abstract
A screw-on disposable underwater concrete conduit head comprises a section of special conduit (1) and a steel tapered conduit head (2), and the steel tapered conduit head (2) can be in threaded connection with the special conduit. The upper portion of the special conduit is identical to an existing tremie concrete conduit in diameter, and the end of the lower portion of the conduit is provided with an external thread. The tapered conduit head is a steel structure component with a cylindrical upper portion and a conical lower portion, an inner ring of the upper cylindrical structure is provided with an internal thread, matched with the conduit end, of the tapered conduit head, 3-4 steel plate blades are uniformly distributed on the outer periphery of a conduit head cone along a cone bus, and an air hole is drilled at the conical position of the conduit head. The screw-on disposable underwater concrete conduit head solves the problem that underwater concrete pouring quality is affected severely due to the fact that faults in an underwater concrete pouring process occur for a long time or cannot be processed after occurred, and also solves the special process problems of probability that conduits need to be added during construction and the like, and is applicable to tremie concrete.
Description
Technical field
The present invention relates to a kind of i.e. disposable underwater concrete conductor housing of usefulness soon, belong to building operations Zhuan and be equipped with Ji Shu Collar territory.
Background technology
Fast development along with the traffic transport industry infrastructure construction, the continuous acceleration of urbanization process, pile foundation, construction of continuous concrete wall etc. all face an identical difficult problem, i.e. pouring underwater concrete in the bases such as bridge foundation pile foundation construction, cushion cap back cover, high level and super highrise building.The maximum difficult problem of underwater concrete perfusion is fault such as pipe to occur leaking, leak gas, fall, in case go wrong, will directly lead to disastrous consequence, even if in time pinpoint the problems, but owing to residing position and construction environment, is difficult to do over again or keep in repair.Therefore how smoothly again success carry out the big difficult point that underwater concrete construction is present engineering construction.
The catheterized reperfusion underwater concrete is a kind of method the most frequently used in the present underwater concrete method for filling, and this method is to carry out the operation of concreting by devices such as conduits, and long duct is adopted to be threaded by the tubulature of many identical calibers and forms.During the cast beginning, rely on the concrete pressure promotion water proof plug (or ball) that pours into to manage interior water or mud and squeeze away, then because conduit lower tube internal pressure greater than the pipe external pressure, makes the concrete of cast boost from managing the end, shown in Fig. 5,6,7.Top of concrete and water contact portion possibility quality are loose, can in the end remove (cutting).This underwater concrete construction method can guarantee good pouring quality, therefore is widely adopted, and is usually used in diaphragm wall, irritates the back cover under water of post, open caisson and caisson etc.But also there are some problems in this underwater concrete construction method: conduit can not be pulled out in filling process, can not insert arbitrarily in filling process; Conduit is because being straight pipe and being in water that inner chamber can not be by prior fill concrete; Particularly conduit breaks down and is difficult to handle midway.
Summary of the invention
The objective of the invention is, the present invention is directed to the serial problem in the underwater concrete filling process, basic principle according to the underwater concrete perfusion, existing conduit system is improved, add a disposable interim tapered tube head in existing conduit lower end, namely design a kind of i.e. disposable underwater concrete conductor housing of usefulness soon.
Technical scheme of the present invention is, the present invention namely soon the disposable underwater concrete conductor housing of usefulness comprise a special conduit of joint and can with the steel pig tail catheter head of described special conduit by being threaded.Described special conduit, its top is consistent with the conduit caliber of existing tremie concrete, and the lower guide tube end has external screw thread; Described pig tail catheter head is that a top is cylindrical shape, the bottom is conical steel construction piece, the inner ring of top cylinder shape structure has the pig tail catheter head internal thread that matches with end of conduit, special conduit is left-hand thread with the screw thread that connects between the pig tail catheter head, be that hand of spiral is opposite with common conduit, when special conduit will screw out from the pig tail catheter head, the above connecting duct screw thread of special conduit can revolve tighter and tighter, have only the screw thread at conductor housing place to revolve more loose and more loose, screw out from special conduit lower end thereby be convenient to the pig tail catheter head.Pig tail catheter head inside is conical cavity, is evenly distributed with 3～4 steel plate blades at conductor housing bullet excircle along element of cone, becomes the sources of resistance that conduit inserts again in order not make blade, also the blade bottom can be made arc and be processed into edge of a knife shape; Conductor housing taper position is along element of cone Drilling 3 row φ 10mm～φ 15mm pores, and pore between row and row staggers mutually, i.e. the following row upright position of the pore of arranging down between row's two pores; Pore passes cone wall.
The present invention adopts a joint special conduit (long 1-1.5m) in the lower end of existing conduit, its upper end is consistent with existing conduit, in order to normally connect with existing conduit, the end of conduit of described special conduit bottom has external screw thread, in order to connect the internal thread of bottom pig tail catheter head, its hand of spiral is opposite with the above common conduit connecting thread of special conduit, is convenient to lay down in filling process the pig tail catheter head.During use, after being connected with the special conduit insertion underwater concrete pouring layer of pig tail catheter head, the clockwise direction steering nozzle, because the screw thread that special conduit bottom is connected with the pig tail catheter head is counter-clockwise direction, vaned resistance in addition, thus conductor housing can be turned on, after screw thread gets loose, mention conduit slightly, conductor housing is stayed in the concrete, owing to be metal product, can not influence workmanship, after conductor housing is sloughed, just can carry out underwater concreting according to a conventional method.
The present invention's beneficial effect compared with the prior art is, the invention solves for a long time and can not break down in the underwater concrete filling process, or can't handle after breaking down, have a strong impact on the difficult problem of underwater concrete pouring quality, solved the special process problems such as possibility that need newly-increased conduit in the construction simultaneously.It is simple, easy to use that the present invention processes, and only needs the in-situ conduit system is added the special conduit of joint and a conductor housing, and do not need to change existing conduit underwater concrete perfusion system; Use equally with existing underwater concrete conduit using method, slough after only needing the pig tail catheter head unscrewed and get final product.
The present invention is adapted at tremie concrete and uses.
