Description

Double-layer sewage draining pipeline

Technical Field

The utility model relates to a sewage treatment technical field especially relates to a double-deck sewage pipes.

Background

Along with the rapid development of cities, underground pipelines of the cities are laid more and more, the drainage efficiency of a drainage pipeline influences the drainage quality and efficiency of a drainage system, and the existing drainage pipeline is often blocked to influence drainage, is easy to smell and is difficult to manage; the existing sewage discharge pipeline cannot effectively isolate a drainage pipeline, and the pipeline is mostly a layer, so that impurities and sewage are not easy to separate, and the use is inconvenient.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the above problem and providing a stable in structure simple to use, the installation of being convenient for is dismantled, and can prevent that impurity from influencing the double-deck sewage pipes of drainage.

The utility model provides a technical scheme that above-mentioned technical problem adopted is: the utility model provides a double-deck sewage pipes, includes outer tube and inner tube, the both ends of outer tube are equipped with the clamping ring, the outer tube is as an organic whole with the clamping ring, be equipped with the connecting hole around the clamping ring, be equipped with connecting hole and mounting groove on the clamping ring, the both ends of inner tube are equipped with the fixed block, be equipped with the counter bore on the fixed block, be equipped with fixing bolt in the counter bore, the inner tube passes through fixed block and mounting groove cooperation and passes through fixing bolt at counter bore and outer tube fixed connection, be equipped with the slotted hole around the.

Preferably, the thickness of the fixing block is consistent with the depth of the mounting groove.

Preferably, a through hole is formed in the counter bore, and the fixing bolt penetrates through the through hole and is fixed on the outer tube.

Preferably, a sealing gasket is arranged on the outer side of the connecting ring.

Preferably, the slot is rectangular.

The utility model discloses a double-layer sewage pipeline, which comprises an outer pipe and an inner pipe, wherein the two ends of the outer pipe are provided with connecting rings, the outer pipe and the connecting rings are integrated, connecting holes are arranged around the connecting rings, the connecting rings are provided with connecting holes and mounting grooves, the two ends of the inner pipe are provided with fixed blocks, counter bores are arranged on the fixed blocks, fixing bolts are arranged in the counter bores, the inner pipe is matched with the mounting grooves through the fixed blocks and is fixedly connected with the outer pipe through the counter bores through the fixing bolts, and slotted holes are; this novel double-deck sewage pipes stable in structure simple to use, the installation of being convenient for is dismantled, and can prevent that impurity from influencing the drainage, is fit for using widely.
