Drainage pipeline non-excavation short pipe replacement construction process
The invention discloses a drainage pipeline non-excavation short pipe replacement construction technology, and relates to the field of drainage pipeline construction, the drainage pipeline non-excavation short pipe replacement construction technology comprises the steps that an original pipe is squeezed and crushed, a new pipe is dragged back, the new pipe comprises a special new pipe structure, the new pipe structure comprises a new pipe body, and a thickening layer is arranged on the outer side of the new pipe body; the outer side of the thickening layer is provided with an edge-following oblique angle in a protruding mode, a groove is further formed in the position, located on the outer side of the thickening layer, of one side of the edge-following oblique angle, and the groove is filled with hard filler. The thickening layer used for thickening and reinforcing is additionally arranged on the outer side of the new pipe body, the edge-following bevel angle capable of reducing friction force with an original pipeline is additionally arranged on the outer side of the thickening layer, the contact area between the edge-following bevel angle and the original pipeline is small, the friction force is small, the dragging direction is the same as the inclination direction of the edge-following bevel angle, resistance is reduced to a certain degree, and the service life of the pipeline is prolonged. The new pipe back-dragging process is smoother, the damage degree of the new pipe after back-dragging is small, and the service life is prolonged.
本发明公开了一种排水管道非开挖短管置换施工工艺，涉及排水管道施工领域，包括挤压破碎原管和回拖新管，所述回拖新管包括特殊的新管结构，且新管结构包括新管主体，所述新管主体的外侧设置有加厚层，且加厚层的外侧突出设置有顺边斜角，所述顺边斜角的一侧位于加厚层的外侧还开设有凹槽，且凹槽的内部填充有硬质填充。本发明实现了在新管主体的外侧加设了用于加厚加固的加厚层，又在加厚层的外侧加设了可减少与原管道摩擦力的顺边斜角，顺边斜角和原管道的接触面积小，摩擦力小，且拖动方向和顺边斜角的倾斜方向相同，一定程度上减少了阻力，新管回拖的过程更加顺利，新管回拖之后的损坏程度小，使用寿命延长。
