Description
Technical Field
The utility model relates to a single-hole double-layer HDPE high-rib winding reinforced pipe.
Background
The existing plastic drainage pipe is limited in manufacturing process and cost, so that the existing plastic drainage pipe is rarely applied to large-diameter plastic drainage pipes (DN 2000-3000), and cement pipes and nodular cast iron pipes are mainly used in the prior art; the traditional product is not an environment-friendly product, and can cause pollution; the pipeline is easy to block due to the defects of the product, and the construction is difficult due to the heavy weight of the pipeline; because the requirement for treating the pipe base is high, the large-caliber cement pipe or the nodular cast iron pipe needs to be connected with a pipe pier in the construction process, and the construction cost is increased.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a single-hole double-layer HDPE high-rib winding reinforced pipe which can meet the requirement of high ring rigidity of a plastic drainage pipe with a large diameter of DN 1600-DN 3000 CM.
The single-hole double-layer HDPE high-rib winding reinforced pipe comprises a pipe body, wherein the pipe body is composed of an HDPE bottom belt serving as a pipe wall and a trapezoidal reinforcing rib strip wound on the pipe wall, and the trapezoidal reinforcing rib strip is formed by coating a PP corrugated pipe with a trapezoidal cross section by an HDPE molten material flow; one end of the pipe body is provided with a socket, and the other end of the pipe body is provided with a socket; the trapezoidal reinforcing rib strip and the bottom belt are overlapped and wound in a staggered mode to form double layers of trapezoidal reinforcing ribs, and the cross sections of the reinforcing ribs are arranged in a shape like the Chinese character 'pin'.
The cross section of the PP corrugated pipe is rectangular, triangular or circular.
The utility model has the beneficial effect that the high-ring rigidity requirement of the plastic drain pipe with the large caliber of DN 1600-DN 3000 can be realized.

Detailed Description
The utility model relates to a single-hole double-layer HDPE high-rib winding reinforced pipe, which comprises a pipe body as shown in figures 1, 2 and 3, wherein the pipe body is composed of an HDPE bottom belt 3 serving as a pipe wall and a trapezoid reinforced rib strip wound on the pipe wall, and the isosceles trapezoid reinforced rib strip is formed by coating a PP corrugated pipe 2 with an isosceles trapezoid cross section by an HDPE melt flow coating layer 1; one end of the pipe body is provided with a socket 4, and the other end of the pipe body is provided with a socket 5; the isosceles trapezoid reinforcing rib strip and the bottom strip are overlapped and wound in a staggered mode to form double layers of trapezoid reinforcing ribs, and the cross sections of the double layers of trapezoid reinforcing ribs are arranged in a shape like a Chinese character 'pin' 6.
The cross section of the PP corrugated pipe is rectangular, triangular or circular.
The embodiment of the utility model adopts the PP corrugated pipe with the isosceles trapezoid cross section, and the production steps are as follows:
1) continuously producing an isosceles trapezoid PP corrugated pipe on corrugated pipe production equipment, and rolling and packaging for later use;
2) the isosceles trapezoid PP corrugated pipe passes through a coating die, the temperature of the coating die is 220-230 ℃, HDPE melt extruded by the coating die is coated on the isosceles trapezoid PP corrugated pipe to form a reinforcing rib strip with an isosceles trapezoid cross section;
3) trapezoidal reinforcing rib strip is drawn to the cask mould of a set of hot attitude after the cooling is finalized the design on, cask mould temperature is about 200 degrees, and the head and the tail of cask mould are equipped with the model of bellmouth and socket respectively, and the HDPE end is taken at first on the cask mould and is formed the bellmouth blank with the winding of bellmouth model, and trapezoidal reinforcing rib strip is hugging closely the HDPE end and is taken the winding on the cask mould: heating and pressing the HDPE bottom belt and the edges of the lower parts of the trapezoidal reinforcing rib belt materials to form a pipe, finally winding the HDPE bottom belt on a socket model on a barrel mould to form a socket blank, and integrally forming the pipe and the socket blank to form an HDPE trapezoidal high-rib winding pipe body and socket blanks at two ends;
4) on the trapezoidal high muscle winding body of HDPE that forms, add the winding again: under the action of heating equipment, after the surface of the pipe body reaches a welding state, winding a second layer of the trapezoidal reinforcing rib strip and the HDPE bottom strip, and staggering an upper layer of the trapezoidal reinforcing rib strip and a lower layer of the trapezoidal reinforcing rib strip into a shape like a Chinese character 'pin' to be uniformly arranged to form a single-hole double-layer HDPE high-rib winding reinforcing pipe;
5) and the bell and spigot of the single-hole double-layer HDPE high-rib winding reinforced pipe passes through a cutting device to form a qualified bell and spigot.
The utility model can realize the requirement of high ring rigidity of the DN 1600-DN 3000 large-caliber plastic drainage pipe.
The following is the detection report of HDPE double-layer single-hole trapezoidal rib winding pipe with the diameter of 2000mm for inspection:
