Description

Technical Field

[0001] The utility model relates to the technical field of concrete drainage pipes, in particular to an anti-leakage reinforced concrete drainage pipe. Background Art

[0002] Reinforced concrete drainage pipes are widely used in rainwater, sewage, drinking water and farmland irrigation projects. Small-diameter drainage pipes with a diameter of less than 1200mm are produced and transported horizontally, and large-diameter drainage pipes with a diameter of more than 1350mm are mostly produced and transported vertically. When in use, the drainage pipe is placed in the excavated channel, and the joints are filled with concrete and then covered with soil. In order to prevent water leakage, the reinforced concrete drainage pipe will be equipped with sealing components at the interface. This kind of reinforced concrete drainage pipe is collectively called anti-leakage reinforced concrete drainage pipe;

[0003] When installing existing anti-leakage reinforced concrete drain pipes, they are often hoisted into the ditch by external hoisting equipment through slings. However, when the drain pipe falls into the ditch, the hoisting slings will be pressed by the drain pipe. Due to the large friction between the drain pipe and the slings and between the slings and the ground, it is difficult for workers to pull out the slings. If the slings are lifted by external hoisting equipment, the drain pipe may rotate when the slings are lifted, which may easily cause damage to the drain pipe or other safety accidents. Therefore, we propose an anti-leakage reinforced concrete drain pipe. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. When the existing anti-leakage reinforced concrete drainage pipe is installed, the drainage pipe is often hoisted into the ditch by an external lifting device through a sling. However, when the drainage pipe falls into the ditch, the lifting sling will be pressed by the drainage pipe. Due to the large friction between the drainage pipe and the sling and between the sling and the ground, it is difficult for the staff to pull out the sling. If the sling is lifted by an external lifting device, the drainage pipe may rotate when the sling is lifted, which may easily cause damage to the drainage pipe or other safety accidents.

The design of the drain outlet 101 enables the drain pipe body 1 to drain water, and the mounting ring 102 can help to install and fix the drain pipe body 1.

[0031] A plurality of threaded holes 103 are equidistantly arranged on the outer wall of the mounting ring 102, and the threaded holes 103 are matched with external fixing bolts. The threaded holes 103 are matched with the external fixing bolts, so that the staff can install and fix the mounting ring 102 through the external fixing bolts.

[0032] A sealing gasket 104 is bonded to the outer wall of the drain outlet 101. The sealing gasket 104 is made of rubber material. The sealing gasket 104 made of rubber material can seal the interface when fixed between the mounting rings 102. The sealing gasket 104 made of rubber material has good sealing effect and a long service life.

[0033] The lifting trough 2 is compatible with the external sling, and the guide block 201 is designed in a clockwise direction. The guide block 201 is made of stainless steel. The lifting trough 2 is compatible with the external sling, so that the staff can lift the drainage pipe body 1 through the external lifting equipment, and the guide block 201 designed in a clockwise direction can be more convenient when the sling needs to be pulled out, and the guide block 201 made of stainless steel has a long service life.
