Abstract
The utility model discloses a prestressed concrete cylinder pipe (PCCP) engineering accident reserve pipe. The PCCP engineering accident reserve pipe comprises a pipe body, wherein an inserting mouth steel ring is arranged at one end of the pipe body, a bell mouth steel ring is arranged at the other end of the pipe body, a telescoping joint is arranged between the inserting mouth steel ring and the bell mouth steel ring, the telescopic joint is fixedly arranged on the pipe body through a screw rod and a fastening bolt, a rubber sealing ring is arranged at the inserting mouth steel ring end of the pipe body, and a reinforcing ring is arranged at the bell mouth steel ring end of the pipe body. Due to adoption of the PCCP engineering accident reserve pipe of the structure, work with water can be achieved, sealed performance is good, meanwhile, the construction difficult degree is reduced, mounting speed is high, and the PCCP engineering accident reserve pipe has long service life.
Description
Technical field
The utility model relates to a kind of tubing, especially relates to a kind of PCCP engineering accident standby pipes.
Background technique
At construction fields such as present hydraulic engineering, electric power plant circulating water engineering and urban water supply and sewerages, more and more used PCCP (Prestressed concrete cylinder pipe) pipeline.PCCP piping erection is bayonet joint, in the normal water supply process, in case accidents such as PCCP pipe leakage, booster occur owing to the accidental force reason, causes for the zone of paddling and have a strong impact on.The pipeline breaking situation takes place after, need rush to repair, present emergency repair method is managed to substitute for the making steel closes up and damaged PCCP pipeline occurred.But there is following shortcoming in this technology: 1, closing up pipe welding can not submersible, needs before the welding the interior whole emptyings of water of pipe; 2, difficulty of construction is big, and installing needs substep to install, and the repairing cycle is longer; 3, production time long, working life is low.
The model utility content
The purpose of this utility model provides a kind of PCCP engineering accident standby pipes, can submersible, and closed performance is good, reduces difficulty of construction simultaneously, and installation rate is fast, possesses long working life.
For achieving the above object, the utility model provides a kind of PCCP engineering accident standby pipes, comprise body, described body one end is provided with socket steel ring, the other end of described body is provided with the bellmouth steel loop, is provided with slip joint between described socket steel ring and the described body, and described slip joint is fixed on the described body by screw rod and clamping bolt, the socket steel ring end of described body is provided with rubber seal, and the bellmouth steel loop end of described body is provided with stiffening ring.
Preferably, described body surface is provided with concrete cover, is provided with steel fabric sheet in the described concrete cover.
Preferably, described body is provided with flange plate.
Therefore, the utility model adopts the PCCP engineering accident standby pipes of said structure, can submersible, and closed performance is good, reduces difficulty of construction simultaneously, and installation rate is fast, possesses long working life.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model PCCP engineering accident standby pipes embodiment's a structural representation.
Embodiment
Embodiment
Fig. 1 is the utility model PCCP engineering accident standby pipes embodiment's a structural representation, as shown in Figure 1, comprise body 1, body 1 is provided with flange plate 11, body 1 one ends are provided with socket steel ring 2, and the other end of body 1 is provided with bellmouth steel loop 3, are provided with slip joint 4 between socket steel ring 2 and the body 1, slip joint 4 is fixed on the body 1 by screw rod 5 and clamping bolt 6, and screw rod 5 is selected positive left-hand thread screw rod for use.The socket steel ring end of body 1 is provided with rubber seal 7, present embodiment is selected for use and is adopted spigot and socket type rubber seal figure, the slip flexible sealing, size is accurate, the fit tolerance of radial direction is in 1mm, rubber seal 7 in special aprons slot with after joint socket docks, three pressurizeds of cushion rubber, thus guaranteed the sealing of joint.
Behind original PCCP piping failure, the staff at first takes out the PCCP pipeline of structural failure, the present embodiment that will complete in advance lies in a horizontal plane in more replace tubes position then, unclamp clamping bolt, earlier present embodiment one end is connected with the PCCP pipeline, utilizes the other end of reach installation present embodiment of the screw rod 5 promotion slip joints 4 of positive left-hand thread to get final product then.
The bellmouth steel loop end of body 1 is provided with stiffening ring 8.Present embodiment is by the design of stiffening ring 8; thickness of earth-fill cover according to pipeline designs stiffening ring 8 in body 1 outside; can bear very high working pressure and external load simultaneously; body 1 surface is provided with concrete cover 9; be provided with steel fabric sheet 10 in the concrete cover 9; all by forming the steel-wire-net reinforced concrete protective layer, simultaneously again can improve the ability of bearing working pressure and external load of present embodiment steel plate being carried out corrosion-resistant in the medial and lateral of body 1 by steel fabric sheet 10.Concrete cover 9 is according to concrete characteristic, and the intensity of itself and hardness often strengthen along with the increase in age, makes present embodiment have good anti-corrosion and durability.
Present embodiment does not have specific (special) requirements to base when mounted, backfill can be with the original soil that digs out on the spot, it is fast that laying speed is installed, the present embodiment joint design is two rubber seal forms simultaneously, after the installation, can carry out the joint hydrostatic test at once, guarantee installation quality, accelerate installation progress.
Therefore, the utility model adopts the PCCP engineering accident standby pipes of said structure, can submersible, and closed performance is good, reduces difficulty of construction simultaneously, and installation rate is fast, possesses long working life.
It should be noted that at last: above embodiment is only in order to explanation the technical solution of the utility model but not limit it, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that: it still can make amendment or be equal to replacement the technical solution of the utility model, and these modifications or be equal to replacement and also can not make amended technological scheme break away from the spirit and scope of technical solutions of the utility model.
