Abstract

A kind of reinforced concrete sewer pipe, comprise concrete, be arranged on outer rack and internal layer rack in concrete, described outer rack and internal layer rack are to be all made up of multiple hoop muscle of indulging muscle and be arranged on vertically on vertical muscle, its special way is: the position, both sides that is positioned at outer rack on described outer rack between every two adjacent hoop muscle is equipped with the outer stiffening rib of arcuation that multiple length increases progressively, and the upper and lower parts on described internal layer rack between every two hoop muscle are equipped with the interior stiffening rib of arcuation that multiple length increases progressively.Beneficial effect is: this reinforced concrete sewer pipe, simple in structure, reasonable in design, on outer rack and internal layer rack, be equipped with the arcuation stiffening rib that multiple length increases progressively, before having replaced, whole ring is to muscle, and can reach same quality standard, bearing capacity is unaffected, saves amount of reinforcement, greatly cost-saving.

Description

Reinforced concrete sewer pipe

Technical field

The utility model relates to a kind of reinforced concrete sewer pipe.

Background technique

Waste pipe is mainly used in underground sewage pipe network engineering, in use mainly plays conveying sewage, carrying earthing, the function of the weight of vehicle and deposit above earthing.Large-diameter steel reinforced concrete drainage pipe rack all adopts double layer design, the structure muscle that wherein inside and outside layer longitudinal steel bar is waste pipe, play the effect of net rack forming, little to the effect of waste pipe bearing capacity, what mainly play bearing capacity effect is the circumferential reinforcement of internal and external layer.

The bearing capacity difference at the each position of circumferential reinforcement, when use, tensile stress is born in internal layer rack circumferential reinforcement upper and lower part, and pressure stress is born in outer rack circumferential reinforcement upper and lower part, and now outer rack upper and lower part circumferential reinforcement plays a role hardly; Meanwhile, outer rack circumferential reinforcement arranged on left and right sides is born tensile stress, and the left and right two-part of internal layer rack circumferential reinforcement are born pressure stress, and now inner layer net left and right sides part hoop muscle plays a role hardly.Known, in the time that being under pressure, waste pipe only have internal layer bar frame circumferential reinforcement upper and lower part and the left and right part of outer reinforcement rack circumferential reinforcement to play Main Function.

In production process, the inside and outside layer of above-mentioned waste pipe rack is all to fit together after adopting seam welder automatic moulding, and inside and outside layer net circumferential reinforcement is all that evenly weldering is put on vertical muscle traditionally, has caused the waste of reinforcing bar.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of simple in structure, saving amount of reinforcement, does not reduce bearing capacity, reinforced concrete sewer pipe reasonable in design, cost significantly reduces.

Technical solution of the present utility model is:

A kind of reinforced concrete sewer pipe, comprise concrete, be arranged on outer rack and internal layer rack in concrete, described outer rack and internal layer rack are to be all made up of multiple hoop muscle of indulging muscle and be arranged on vertically on vertical muscle, its special way is: the position, both sides that is positioned at outer rack on described outer rack between every two adjacent hoop muscle is equipped with the outer stiffening rib of arcuation that multiple length increases progressively, and the upper and lower parts on described internal layer rack between every two hoop muscle are equipped with the interior stiffening rib of arcuation that multiple length increases progressively.

The beneficial effects of the utility model are:

This reinforced concrete sewer pipe, simple in structure, reasonable in design, on outer rack and internal layer rack, be equipped with the arcuation stiffening rib that multiple length increases progressively, replaced former whole ring to muscle, and can reach same quality standard, bearing capacity is unaffected, save amount of reinforcement, greatly cost-saving.

Brief description of the drawings

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

Fig. 2 is the structural representation of the inside and outside layer of the utility model rack.

In figure: 1-concrete, the outer rack of 2-, 3-internal layer rack, 4-longitudinal rib, 5-hoop muscle, the outer stiffening rib of 6-, stiffening rib in 7-.

Embodiment

As shown in the figure, the reinforced concrete sewer pipe that the utility model relates to, comprise concrete 1, be arranged on outer rack 2 and internal layer rack 3 in concrete 1, described outer rack 2 and internal layer rack 3 are to be all made up of vertical muscle 4 and multiple annular ribs 5 of being in axial direction arranged on vertical muscle 4, the position, both sides that is positioned at outer rack 2 on described outer rack 2 between every two adjacent hoop muscle 5 be equipped with arcuation that multiple length do not wait outward stiffening rib 6(the present embodiment taking 3 as example); The upper and lower parts that are positioned at internal layer rack 3 on described internal layer rack 3 between every two hoop muscle 5 are equipped with arcuation stiffening rib 7(the present embodiment that multiple length do not wait taking 3 as example).

When use, by packing in mould after this reinforced concrete sewer pipe rack assembling, add concrete, make waste pipe, on pipe die, carry out upper and lower part mark, when the tubing demoulding, also must carry out upper-lower position mark, when installation, must install according to upper-lower position.

Claims

1. a reinforced concrete sewer pipe, comprise concrete, be arranged on outer rack and internal layer rack in concrete, described outer rack and internal layer rack are to be all made up of multiple hoop muscle of indulging muscle and be arranged on vertically on vertical muscle, it is characterized in that: the position, both sides that is positioned at outer rack on described outer rack between every two adjacent hoop muscle is equipped with the outer stiffening rib of arcuation that multiple length increases progressively, and the upper and lower parts on described internal layer rack between every two hoop muscle are equipped with the interior stiffening rib of arcuation that multiple length increases progressively.
