The utility model relates to a winding pipe socket joint type water swelling, sealing and connecting device. The device comprises a left screw winding pipe and a right screw winding pipe which are butted, and a connecting faucet, wherein the connecting faucet is sheathed on an outer ring of the left winding pipe or the right winding pipe. A fixed connecting piece is arranged between an inner ring of the connecting faucet and the outer ring of the screw winding pipe, and the fixed connecting piece is fixedly connected between the left screw winding pipe or the right screw winding pipe and the connecting faucet. A sealing device is sheathed on the outer ring at one end of the screw winding pipe at the opposite side of the screw winding pipe which is fixedly provided with a connecting faucet sleeve. Therefore, the deformation generated by pressing after the pipe is embedded into ground can be effectively solved, the connecting sealability of joints can be ensured, the leakage of the joints can be eliminated, and the connecting technique of buried pipes with large calibers under the environment, such as watery environment, much underground silt, complicated underground structure, etc. can be effectively improved. The utility model has the advantages of convenient construction and much labor saving.
Description
Technical field
The utility model relates to a kind of connection set of large-caliber spiral entwining tube, especially relate to a kind of many water area that is applicable to, the hollow wall spigot and socket type water swelling seal connection that buries ground draining spiral winding pipe of level of ground water is high and underground silt is more and the city underground structure complexity has stable political situation dwelling construction sub-district.
Background technique
The Placement of existing spiral winding pipe has following four kinds, and following shortcoming is arranged respectively:
(1) connection of Electric thermal smelting belt: the pipe bed hedgehopping is arrived certain height and maintenance level, remove the impurity and the moisture on surface, Electric thermal smelting belt tighten on connected pipe with buckle withhold tight, reinforce with Stainless Steel Wire again, after connecting the power supply at thermal capacitance machine and hot melt band two ends, set hot molten time, weld.This connecting means is for being rigidly connected, and buries to be subjected to the pressure on ground behind the ground or to become distortion and the cracking that row, sedimentation cause pipe easily.The intensity of this connecting means is better.But be unwell to submersible.
(2) pipe clamp connects: one deck PE material is wrapped in the spiral winding pipe joint, asphalt felt is being wrapped in the outside, makes pitch slightly molten with the flame gun heating, then the stainless steel collar is put tightening the screw.This connecting means is unwell to the operation of band water, and is very big with the personal factor of flame gun heating, the join strength inequality of spiral winding pipe.
(3) heat-shrinkable tube connects: construction makes two tubes dock with sleeve pipe, uses flame heating, and sleeve pipe shrinks and connects pipe.This connecting means is not suitable for submersible, and sleeve pipe connects the spiral winding pipe distortion that can not guarantee underground pipe and cause owing to a variety of causes, the sealability of displacement after row establishes.
(4) flange connects: the flange of embedding electric heating wire is connected on the pipe in advance.With adpting flange with screw connect tight after, energising makes flange and flange welding, this connecting means is for being rigidly connected, and is subjected to the pressure on ground or distortion and the cracking that change is gone, sedimentation causes pipe easily after burying ground.The intensity of this connecting means is better.But be unwell to submersible.
Shanghai is to belong to the higher many water area of level of ground water, excavates generally that 0.6-0.8 rice is dark just underground water, and the underground silt of some places is more, and underground structure is difficult to survey.More than 4 kinds of methods of Jie Shaoing at all can't operation in above-mentioned environment, the connection that more can't solve heavy caliber high density polyethylene (HDPE) (HDPE) underground pipe.The utility model provides a kind of hollow wall entwining tube connected water swelling seal connection, has effectively solved the above problem.
Summary of the invention
The purpose of this utility model is to propose a kind of hollow wall entwining tube connected water swelling seal connection, owing to adopted mechanical hot melt or manually welded bellmouth, can directly machine in the workshop, cooperate the water-swellable cushion rubber, make heavy caliber bury the ground spiral winding pipe in water and in the complicated underground structure socket joint construction more convenient and suitable.
The purpose of this utility model is achieved in that a kind of winded pipe spigot-and-socket water swelling seal connection, the spiral winding pipe that comprises butt joint about two is connected bellmouth with one, it is characterized in that, on the outer ring of the described entwining tube on described connection bellmouth cover on the left side or the right; Be provided with fixed connecting piece between the outer ring of described connection bellmouth inner ring and described spiral winding pipe, the spiral winding pipe that described fixed connecting piece is fixedly connected on the described left side or the right is connected between the bellmouth with described; A sheathed seal arrangement on the outer ring of an end of the described spiral winding pipe of the described relative side of described spiral winding pipe that is fixed with described connection bellmouth cover.The outer ring of described connection bellmouth inner ring and described spiral winding pipe be cemented in the top of described fixed connecting piece and below.
Described spiral winding pipe is the Hollow wall tube that high density polyethylene (HDPE) is made with the described bellmouth that is connected.
Described fixed connecting piece can be that two square tube circles are cemented between the outer ring of described connection bellmouth inner ring and described spiral winding pipe side by side.
Described seal arrangement is met the dilatable cushion rubber of water by rubber heelpiece that is close to described spiral winding pipe outer ring and snare and is formed on described rubber heelpiece.
There is certain space on the top of described water-swellable cushion rubber apart from described bellmouth, and described water-swellable cushion rubber is no more than the right-hand member outer of described connection bellmouth farthest from described fixed connecting piece.
Be provided with tight circle band in the both sides of described water-swellable cushion rubber.
The depression bar that two symmetries are arranged on the described water-swellable cushion rubber.
Owing to adopting such scheme, used the complex technique of bellmouth connection with the water-swellable cushion rubber, the expansion cushion rubber is met 2.5-3 times that water can expand into original sectional dimension in 4-7 hour, and this joint can reach the ring stiffness equal with pipe, inner pressure test 〉=0.5Mpa.Because the connecting means of adopting is to flexibly connect, connect bellmouth flexible leeway is spatially arranged, having solved pipe thus buries pressurized behind the ground and produces the influence that distortion brings, guaranteed that joint is subjected to the connection sealing of pressure outside distortion or surface subsidence distortion, also can get rid of damage and joint seepage that pipeline is affected by thermal expansion and contraction and causes, effectively improved the heavy caliber underground pipe at Duo Shui, underground silt is more, the interconnection technique under the environment such as underground structure complexity.And easy construction, save a large amount of employees.
