Casing pipe type water conveying pipeline applied to crossing bridge and installation and construction method thereof

Abstract

The invention discloses a casing pipe type water conveying pipeline applied to a crossing bridge and an installation and construction method thereof. The construction method comprises the following steps of: step 1. excavating a water conveying pipeline trench; step 2. installing a concrete casing pipe; step 3. backfilling the water conveying pipeline trench; step 4. installing a pressure steel pipe; step 5. filling concrete. A casing pipe type water conveying pipeline comprises the concrete casing pipe, a concrete pouring layer and the pressure steel pipe, wherein the concrete pouring layer is arranged at the outer side of the pressure steel pipe in a sleeving manner; the concrete casing pipe is arranged at the outer side of the concrete pouring layer in a sleeving manner; a supporting device is also connected between the concrete casing pipe and the pressure steel pipe; and steel idler wheels are also fixedly at the bottom of the pressure steel pipe. The construction method has closeworking procedure connection and effectively improves the construction efficiency. The stability of the pressure steel pipe is effectively ensured through the matching of the casing pipe layer structure and the supporting device, so that water is unlikely to seep from the pressure steel pipe.

AI Technical Summary

Benefits of technology

This new technology allows for better ways to protect pipes from leaks caused by cracks or other issues during building constructions. It also enhances the strength and durability of existing structures while maintain their effectiveness over time due to its use of an improved design that matches well-mixed cement layers on top of traditional steel reinforced plates made up of iron bars embedded within them.

Problems solved by technology

This patented describes different methods or techniques for constructing temporary underground passages (such as railways). These involve cutting up holes along the edges where two ends intersect during placement of the tunnel wall. To prevent leakage from these cutings, reinforced layers can also be added between them. However, this adds extra weight compared to traditional ways such as adding mortars inside the walls themselves. Additionally, if the buried depth exceeds certain limits, the use of watertight rubber covers may require more frequent replacements over prolong periods.
