Abstract

The utility model discloses a reinforced concrete drainage pipe with a lining PVC sheet, and belongs to the technical field of concrete pipes. In order to solve the technical problem, the reinforced concrete drainage pipe with the lining PVC sheet has the advantages that the corrosion prevention effect is good, the fixing effect of the lining PVC sheet is good, the caliber is large, the external load carrying capacity is high, and the reinforced concrete drainage pipe can be used as a jacking pipe. To solve the technical problem, by the adoption of the technical scheme, the reinforced concrete drainage pipe with the lining PVC sheet comprises a concrete pipe and a lining pipe, the inner ring of the concrete pipe is sleeved with the lining pipe, the diameter of the outer ring of the lining pipe adapts to the diameter of the inner ring of the concrete pipe, a plurality of T-shaped fixed lugs are evenly distributed on the outer ring of the lining pipe and extend into the pipe wall of the concrete pipe, every two adjacent columns of fixed lugs are arranged in a staggered mode, and every two adjacent lines of fixed lugs are arranged in a staggered mode. The reinforced concrete drainage pipe with the lining PVC sheet can be widely applied to the technical field of corrosion prevention pipes.

Description

The reinforced concrete sewer pipe of lined with PVC sheets

Technical field

The reinforced concrete sewer pipe of the utility model lined with PVC sheets, belongs to concrete plug technical field.

Background technique

Now, along with the fast development of national economy, the input energetically of infrastructure, waste pipe and chemical industry are increasing with consumption and the mouth of pipe footpath of pipe, when waste pipe is used in sewerage or other have under corrosive environment, the waste pipe wearing and tearing that will be corroded fast, because these waste pipes are generally all arranged on underground, dismounting inconvenience, if often change waste pipe because of corrosive wear problem, can cause the waste of manpower and materials, current anticorrosion tubing generally adopts pottery, dual ripple steel strip-plastic pipe, its defect is that caliber is little, external load is too poor, pipe is easily out of shape and formation obstruction, and existing tubing can not be used for push pipe, cost is also higher, can not meet the requirement of modern anticorrosion drainage pipe.

Model utility content

The utility model overcomes the deficiency that prior art exists, and in order to provide, a kind of favorable anti-corrosion effect, inner lining plate good fixing effect, bore are large, external load bearing capacity is strong and can make the concrete drain tile of jacking tube for technical problem to be solved.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the reinforced concrete sewer pipe of lined with PVC sheets, taking concrete pipe as matrix, concrete pipe has been nested with internal lining pipe, the uniform fixing ear of multiple T-shapes that is provided with in outer ring of described internal lining pipe, described multiple fixing ear all extends in the tube wall of concrete pipe, and the fixing ear of described adjacent two row is all crisscross arranged, and the fixing ear of described adjacent two row is all crisscross arranged.

Wherein, described internal lining pipe is corrosion-resistant material.

Wherein, described internal lining pipe is PVC material.

Wherein, in the tube wall of described concrete pipe, be provided with ring in Framework Of Steel Reinforcement, in described Framework Of Steel Reinforcement, between ring and the outer wall of concrete pipe, be provided with Framework Of Steel Reinforcement outer shroud.

The utility model compared with prior art has following beneficial effect.

One, the uniform fixing ear of multiple T-shapes that is provided with in internal lining pipe of the present utility model outer ring, fixing ear extends in the tube wall of concrete pipe, fixing ear can be fixed on internal lining pipe the tube wall inner ring of concrete pipe securely, effectively prevent that internal lining pipe from separating with concrete pipe, and adjacent two row fixing ears be all crisscross arranged, the fixing ear of adjacent two row is all crisscross arranged, like this, can make the stressed of inner lining plate evenly can not cause local unbalance stress, prevent inner lining plate breakage.

Two, internal lining pipe of the present utility model is PVC material, has acidproof, alkaline-resisting and long-lived good characteristic, can make concrete pipe use for a long time under corrosive environment.

Three, in reinforced concrete tube wall of the present utility model, be provided with the interior ring of Framework Of Steel Reinforcement and the Framework Of Steel Reinforcement outer shroud that various load ranks require, the interior ring of Framework Of Steel Reinforcement and Framework Of Steel Reinforcement outer shroud are all shape of threads and are wrapped in tube wall, can meet rigidity of the present utility model and load requirement, avoid the utility model breakage or crackle in use, guaranteed working life of the present utility model.

Brief description of the drawings

Below in conjunction with accompanying drawing, the utility model is described in more detail.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is A-A sectional view of Fig. 1.

Fig. 3 is the structural representation of internal lining pipe of the present utility model.

In figure: 1 is concrete pipe, 2 is internal lining pipe, and 3 is fixing ear, and 4 is ring in Framework Of Steel Reinforcement, and 5 is Framework Of Steel Reinforcement outer shroud.

Embodiment

By reference to the accompanying drawings the utility model is described in further detail now, accompanying drawing is the schematic diagram of simplifying, and basic structure of the present utility model is only described in a schematic way, and therefore it only shows the formation relevant with the utility model.

The reinforced concrete sewer pipe of lined with PVC sheets, comprise concrete pipe 1 and internal lining pipe 2, described internal lining pipe 2 is sleeved on the inwall of concrete pipe 1, the uniform fixing ear 3 of multiple T-shapes that is provided with in outer ring of described internal lining pipe 2, described multiple fixing ear 3 all extends in the tube wall of concrete pipe 1, the fixing ear 3 of described adjacent two row is all crisscross arranged, and the fixing ear 3 of described adjacent two row is all crisscross arranged, described internal lining pipe 22 and concrete reinforced pipe 1 disposal pouring moulding.

Described internal lining pipe 2 is PVC material.

Described internal lining pipe 2 can production pipe jacking method tubing.

Described internal lining pipe 2 can be produced heavy caliber pipe, as the tubing of Ф 3600mm.

In the tube wall of described concrete pipe 1, be provided with ring 4 and Framework Of Steel Reinforcement outer shroud 5 in the Framework Of Steel Reinforcement that meets various requirement, the interior ring 4 of Framework Of Steel Reinforcement and Framework Of Steel Reinforcement outer shroud 5 are shape of threads and are wrapped in concrete pipe 1 body.

When internal lining pipe 2 of the present utility model adopts PVC material, can be for sewer pipe or chemical industry waste pipe, utilize acidproof, the alkaline-resisting and long-lived characteristic of PVC material, the utility model can be worked for a long time under the high environment of corrosivity, can not cause corrosion to concrete pipe 1, stable work in work, durability is high, meets the needs of modern anticorrosion drainage pipe.
