Field of the Invention The present invention relates to an apparatus for straightening a resin buried pipe for sewage pipes or the like, which is to be buried by a Yokobori propulsion burying method. About. 2. Description of the Related Art A conventional straightening device made of resin buried pipes, which is also called open pit mining, is buried by a burial burial method.
An example of a resin buried pipe bending straightening device for correcting a bending of a resin buried pipe is a straightening device described in Patent No. 2567822 "Bending straightening device of a buried vinyl chloride pipe". There is no resin buried pipe bending straightening device that corrects the bending of the resin buried pipe buried from the lateral direction by the construction method. [0003] The procedure of burying a resin buried pipe in the prior art by the horizontal moat propulsion burying method is described in, for example, Japanese Patent Laid-Open No. 10-2739.

As shown in FIG. 3 (A), first, in the execution procedure (A), a starting shaft (30a) having a desired depth is provided at the starting point of the horizontal moat of the soil (30), and further at the end of the horizontal moat. A leading shaft (40a) provided with a reaching shaft (30b) of a desired depth and a propulsion cutter at the tip at the bottom of the starting shaft.
Is set. Next, in the execution procedure (B), as shown in FIG. 3 (B), the propulsion jack (40b) is advanced hydraulically while rotating the propulsion cutter, and the horizontal moat propulsion is started. Next, the enforcement procedure (C)
At this time, as shown in FIG. 3 (C), the propulsion jack is retracted and the screw unit (20) is inserted into the buried pipe unit (10), which is a resin buried pipe unit (10a) having a predetermined length to be buried. Is installed in the propulsion device, and is connected to the rear of the forward conduit, and the horizontal drive is continued, and the screw unit has a screw conveyor function and drives the forward conduit. In addition, the screw has the function of transporting the excavated earth and sand to the start shaft by a screw. Next, in the enforcement procedure (D), as shown in FIG. 3 (D), the operations of the enforcement procedures (B) and (C) are repeated to reach the leading conduit while burying and connecting the buried pipe unit. The shaft is reached, and the leading conduit is recovered from the reaching shaft, a series of execution procedures are completed, the screw unit incorporated therein is recovered from the starting shaft, and the resin-buried pipe unit connected to the resin buried pipe unit is connected. A buried pipe was secured. [0004] There is no resin buried pipe bending correction device for correcting the bending of a resin buried pipe which is buried by the prior art Yokobori propulsion burying method. In such a case, an abnormal curved portion deviating from a straight cylindrical shape occurs, and there is a problem that a fluid such as sewage does not have a smooth flow gradient and sludge or the like stays. [0005] In order to solve the above-mentioned problems, a resin buried pipe bending straightening device according to the present invention comprises a cylindrical body having a predetermined length, the outer circumference of which is made of resin to be buried.

The straightening unit has connecting means consisting of connecting members which can be connected in series to each other, and the inside of the cylinder of the straightening unit can be connected in series with a front pipe equipped with a propelling cutter at the tip, which can be used in the Yokobori propulsion burying method. The unit is characterized in that it has a structure that can be freely inserted and removed at least in the axial direction. In the bending correction device for a buried pipe made of resin according to the present invention, the method of arranging the plurality of roller members on the outer periphery of the cylindrical body includes the steps of forming a plurality of predetermined openings on the outer periphery near both ends of the cylindrical body. In the radial direction of the cylindrical body, in the vicinity of both ends in the rotational direction of the rolling element, the outer circumference of which is coated with a flexible material such as hard rubber, inside and outside a pair of mounting holes of the corrosion-resistant metal body of the roller member. A plate-shaped mounting member is sandwiched by using a spacer having a predetermined thickness that can be adjusted in height, and the end of the opening that is opposed to the opening in the axial direction is sandwiched between the inner and outer ends of the mounting member. -By tightening, the roller member can be disposed in each opening. In the apparatus for straightening bent pipes made of resin according to the present invention, a plurality of connecting holes are provided at both ends of a cylindrical body of the straightening unit as connecting means capable of connecting the straightening units in series with each other.

[0009] The method of use of the resin buried pipe bending straightening device of the present invention is as follows. The straightening unit is inserted into the inner periphery of the resin buried pipe unit to be buried to form a buried pipe unit. While connecting the units, a plurality of the buried pipe units were buried by the Yokobori propulsion burying method, and after a predetermined period of time, the soil around the buried / connected resin buried pipe unit became familiar and sufficiently solidified. After that, the connecting means of the connected straightening unit is pulled out while being sequentially released, and the straightened, buried and connected resin buried pipe unit having a continuous linear curved surface in the axial direction is secured. . The dimensions of the resin buried pipe bending straightening device of the present invention correspond to a resin buried pipe unit having a predetermined outer diameter, thickness, and unit length, such as a vinyl chloride pipe, and the outer diameter of the rolling element of the roller member. Is selected and adjusted and applied by combining the outer diameter and thickness of a cylinder of a predetermined unit length, and the screw unit has a structure that can be freely inserted and removed at least in the axial direction. Can be used. In the method of burying and sewing a sewer pipe or the like to which the resin burying pipe bending straightening device of the present invention can be applied, a propulsion device described in JP-A-10-273999 "Propulsion device for small-diameter pipe burying machine" can be used. . The resin buried pipe bending straightening device of the present invention comprises:
A straightened, buried, and connected resin buried pipe unit with a straight, continuous internal curved surface that is straight in the axial direction can be secured, so fluid such as sewage flowing through the resin buried pipe can be secured.

[0021] The resin straightening pipe bending straightening device of the present invention comprises:
A straightened, buried, and connected resin buried pipe unit with a straight, continuous internal curved surface that is straight in the axial direction can be secured, so fluid such as sewage flowing through the resin buried pipe can be secured.
It provides a flow gradient that flows smoothly and has the effect that sludge and the like do not stay. The resin buried pipe bending straightening device of the present invention comprises:
The simple structure allows it to be used for resin buried pipes of various diameters, is easy to repair and adjust, and can use various commercially available roller members and connecting members, so that it can be manufactured at low cost and can be procured many times. It has an effect that can be used for buried construction methods.
