Abstract

The utility model relates to a novel pipe material which is used for the gas pipeline of the water transmission. The existing pipe material mainly adopts the steel pipe which has big steel material consumption, expensive cost, and needs to be carried out the antiseptic treatment. The novel pipe material is developed for satisfying the requirement of the construction of the city and the countryside under the condition of the serious water shortage on the all the places of the country. The novel pipe material has the advantages of reasonable structure, strong impermeability of the pipe body, high bearing hydraulic pressure, corrosion prevention, labor saving for the installation, convenient installation, etc. Compared with the steel pipe, the utility model can save the steel material of 65% to 75%, can reduce the investment of 35% to 45%, and can prolong the service life in four times. The popularization and the application of the pipe material can generate obvious economical and social benefits.

Description

Prestressed steel pipe concrete pressure pipe

The utility model is a kind of novel tube, is mainly used in water delivery, gas pipeline.Present domestic water delivery gas pipeline adopts steel pipe, cast iron tube more and gives the stress concrete reinforced pipe, and steel pipe costs an arm and a leg, and need carry out preservative treatment because steel consumption more; Cast iron tube is only applicable to small-bore waterline, and bigbore production technology and quality do not reach a standard as yet; It is also stable inadequately to give its quality of stress concrete reinforced pipe, and along with the development of urban construction, especially current all parts of the country are under the situation of serious water shortage, and the development novel tube is one of measure of alleviating urban water shortage.

Task of the present utility model is mainly based on the problem of above-mentioned situation and existence and develop.Giving stress steel cylinder concrete pressure tube is by steel bushing; liner; reinforcement of wire and protective layer are formed; its major character: steel bushing comprises the bellmouth steel ring; steel cylinder; three parts of socket steel ring; wherein steel cylinder is that the weldering of sheet metal volume forms; bellmouth and socket steel ring are that general steel plate is stamped to form; and then carry out assembly welding and connect as one; liner is to adopt silicate self-stressing cement concrete; reinforcement of wire hoop at a certain distance is wrapped on the external diameter of steel bushing; protective layer adopts the ordinary Portland cement mortar, and this pressure tube constitutes the pipe structure (as shown in Figure 1) of slip interface pattern with different materials and moulding process.Give stress steel cylinder concrete pressure tube because giving of steel wire pressed and the liner effect of silicate self-stressing cement, this tubing can produce than strain value greatly and not ftracture when bearing big internal water pressure.

The utility model is a kind of novel tube, have novel and reasonable structure, body impervious strong, hold internal water pressure height, corrosion-resistant, inner wall smooth, saving power consumption, characteristics such as laborsaving convenience be installed, compare with steel pipe, can save steel 65～75%, its investment can reduce by 35～45%, and can prolong four times working life, will produce tangible economic and social benefit for the water delivery gas pipeline of constructing from now on provides novel tube.

(Fig. 1) gives stress steel cylinder concrete pressure tube pipe structure pattern

The mode of finishing below in conjunction with description of drawings the utility model of embodiment:

Steel bushing (1) comprises following three parts, i.e. bellmouth steel ring (5), steel cylinder (6) and socket steel ring (7).Wherein steel cylinder is rolled up weldering on request with sheet metal and is formed, and bellmouth and socket steel ring are stamped to form by steel plate, and then carry out assembly welding and connect as one; Liner (2) is to adopt silicate self-stressing cement concrete mix, obtains with centrifugal molding process in that steel bushing (1) is inboard, need carry out steam-curedly after the moulding, steeps only in the water and be placed on; Reinforcement of wire (3) is wrapped in the outside of steel bushing (1) by the certain spacing hoop; Protective layer (4) is to adopt the spraying of ordinary Portland cement mortar to form, and also need carry out steam curing after protective layer (4) moulding, promptly constitutes the overall structure of giving stress steel cylinder concrete pressure tube.

Claims (1)

1. A kind of stress steel cylinder concrete pressure tube that gives; steel bushing (1) is arranged; liner (2); reinforcement of wire (3); protective layer (4); it is characterized in that steel bushing (1) comprises bellmouth steel ring (5); (7) three parts of steel cylinder (6) and socket steel ring; with different mode moulding after assembly welding connect as one; liner (2) is a silicate self-stressing cement concrete; reinforcement of wire (3) hoop at a certain distance is wrapped in the outside of steel bushing (1); protective layer (4) adopts the ordinary Portland cement mortar; with different materials and technology, what constitute slip interface pattern gives stress steel cylinder concrete pressure tube pipe structure.
