Abstract

A kind of single tube type can carry out the plastic draining pipe bend of angular adjustment, the under ground portion that is used for the indoor and outdoor drainage works is installed, be connected with plastic drain-pipe during use, it is characterized in that: two ends are connected with plastic drain-pipe during installation, between two ends, must there be one section arc plastic round tube to be connected, just can reach the purpose of any adjustment angle with the length that increases or reduce the arc pipe, because its flexibility, so can solve the installation difficulty of underground plastic drain-pipe fully.

Description

A kind of single tube type can carry out the plastic draining pipe bend of angular adjustment

Affiliated technical field

The present invention relates to drainer journey outside architecture indoor, be particularly useful for the installing engineering of plastic drain-pipe under ground portion.

Background technique

At present, known plastic drain-pipe install be by waste pipe be connected with water-drainage tube part extend at last bilge well then installment work finish, water-drainage tube part not only plays the effect that connects waste pipe in installing engineering, and, can also make plastic drain-pipe change certain direction.The pipe fitting kind that existing single tube type plastic drain-pipe under ground portion is installed and used has: 0 ° of pipe collar, 45 ° of elbows, 90 ° of elbows (the building wholesale market is as seen in kind), annotate: reference, water power worker technical ability quick start (51 pages), Nanjing, Jiangsu science tech publishing house, in September, 2006 is because plastic drain-pipe under ground portion installation at present all is just to install after the building construction main body is finished, usually be subjected to obstructions such as building masonry wall again, make most plastic drain-pipe all can not connect in linearly extended mode, so, plastic drain-pipe usually needs 1～3 time direction to change in the bilge well of being allowed for access, and the angle that changes direction in as installed is generally 0 °～90 °, usually is subjected to the influence of bilge well position etc. simultaneously, the people who was engaged in the subsoil drain installation knows that installment work is very difficult.

That what reason causes the installation difficulty so? the analysis reason is as follows:

1. as long as the pipe fitting kind is installed more than floor and can be satisfied the demand fully now, because all be that square body or the construction of the cuboid bodily form form more than the floor, generally 0 ° of pipe collar or 90 ° of elbows;

2. because the angle that plastic drain-pipe changes direction during the installation of underground plastic drain-pipe is uncertain and random, so existing water-drainage tube part kind is difficult to use, such as: the angle that need change direction when us is: 2 °, 8 °, 15 °, 22.5 °, 30 °, 40 °, 50 °, 60 °, 70 °, 80 °, 85 ° etc., at this moment you can find, existing plastic draining pipe fitting kind is stiff or lacks flexibility, usually is that a bit little angular error also can make plastic drain-pipe depart from the destination;

3. usually because under ground piping is intensive, bore is big, and so will pack into 4 or 8 plastic drain-pipes of a bilge well sometimes are the unusual difficulty of installment work.

How does the difficulty that plastic drain-pipe is installed now solve again? it is batchs of often to see that on-site the installer has changed, still finish with deficient at last, still more handy remedial measures or indigenous method just can be finished whole installing engineerings at last, " roasting bellmouth " arranged when implementing such as the most frequently used method, light a fire with some fuel earlier, again to the plastic drain-pipe local heating to the local deliquescing of pipeline, move plastic tube with hand again, force the change direction, make it stretch into the destination, so usually also can make internal diameter of the pipeline become uneven or oval pipe, producing after the installation is blinding, can not allow others find, this indigenous method must have the qualified operation of the talent of confidentiality, estimates that such operation also is in violation of rules and regulations.

Summary of the invention:

In order to overcome the practical difficulty that the plastic drain-pipe under ground portion is installed, cause the root that difficulty is installed to be that again the kind of pipe fitting is single, lack flexibility, usually make the direction substantial deviation destination (bilge well) of the plastic drain-pipe change of installation.

The invention provides the plastic draining pipe bend that a kind of single tube type can carry out angular adjustment, can adjust according to the actual angle that waste pipe changes direction in the time of then solving practical difficulty in the installation and use, so, plastic drain-pipe can arrive at the destination accurately according to people's wish, so installment work also becomes very simple easily.

The present invention solves the technological scheme that its art problem adopted: at first make the circular pipe that a circular pipe (see figure 1) identical with the waste pipe radius gets a segment length then and be connected with plastic drain-pipe, so the direction of plastic drain-pipe also obtains certain change simultaneously, the principles of science of institute's foundation is: a full circle is the track of a point around certain radius, when the angle around an intact circle just equals 360 ° because girth and angle are directly proportional, we are general simultaneously only needs 0 °～90 ° direction to change.

When we need change 90 °, $\frac{90}{360}=\frac{1}{4}$ The usefulness that promptly only needs girth

Get final product

In like manner: when changing 45 °, $\frac{45}{360}=\frac{1}{8}$ Promptly as long as girth

Get final product

When changing 22.5 °, $\frac{22.5}{360}=\frac{1}{16}$ Promptly as long as girth

Get final product

When changing 4.5 °, $\frac{4.5}{360}=\frac{1}{80}$ Promptly as long as girth Get final product

Again: we select different radiuses to make the ring tube of different arcs, will bring accurate more and convenient to installation.

As: 1. when the radius=6.367cm, girth 40cm,

Be connected 90 ° of changeable angles with plastic drain-pipe so separate the x=90 ° of ring tube of getting 10cm length

In like manner: 2. when radius=12.73cm, girth 80cm,

Be connected 45 ° of changeable angles with plastic drain-pipe so separate the x=45 ° of ring tube of getting 10cm length

3. when radius=25.469cm, girth=160cm,

Be connected 22.5 ° of changeable angles with plastic drain-pipe so separate the x=22.5 ° of ring tube of getting 10cm length

4. when radius=254.69cm, girth=1600cm,

Be connected 2.25 ° of changeable angles with plastic drain-pipe so separate the ring tube that x=2.25 gets 10cm length

The invention has the beneficial effects as follows, in underground plastic drain-pipe installing engineering, be again that the fixing stiff installing engineering that usually causes can't be implemented owing to present plastic drain-pipe pipe fitting kind is single, and also handy at last indigenous method just can fulfil assignment.

The present invention can satisfy the actual demand of installing fully.It is very easy that the plastic drain-pipe installment work is become, and simple in structure.
