Abstract
The invention relates to an experimental apparatus for continuous hydraulic pressure used in large-bore water conveying pipeline. The structure of the experimental apparatus is as follows: A main body of the apparatus fits the large-bore water conveying pipe. There is a seal plate on the said main body. Single ring flange short pipe is on the bottom of the seal plate, and a blind plate seals the short pipe. On the lower part of the main body, there is a prepared opening for flange on each side of the seal plate. Communicating pipe is connected to the said two openings, and a valve is installed in the communicating pipe. On the upper part of outside of the main body, a short pipe is fixed on each side of the seal plate. Valve is installed on the short pipe. The invention can carry out the experiment of continuous hydraulic pressure, providing features of shortened experimental time needed, simple operating steps, easy to implement and low construction cost.
Description
The present invention relates to a kind of continuous hydrostatic test device that is used for the heavy caliber aqueduct.
At present, in water supply engineering heavy caliber long-distance pipe hydrostatic test, for satisfying the requirement of " plumbing is executed and tested ", utilize single experiment aqueduct, this frame mode needs every kilometer backrest all is set, the plant equipment, propping material and the pipe fitting that need the use back support to use, can not carry out continuous hydrostatic test, hydrostatic test lasts oversize, the operational sequence complexity, have a strong impact on the construction period, and heavy caliber aqueduct pressure testing undisturbed soil is normal because of the soil is porous, anchorage force is not enough and cause non-construction quality pressure testing to fail; Heavy caliber aqueduct pressure testing water consumption is bigger, and field construction is insufficient water sources often, and pouring water to pressure testing makes troubles; Also have the pound of long-distance pipe to put very complexity of the work of healing up, accessory is many, and execution conditions are poor, improved whole construction costs.
Purpose of the present invention just provides a kind ofly can carry out continuous hydrostatic test, shortens the hydrostatic test time, operational sequence is simple, avoids non-construction quality pressure testing failure, convenient construction, the continuous hydrostatic test device that is used for the heavy caliber aqueduct that reduces cost.
To achieve these goals, technical scheme of the present invention is: a kind of continuous hydrostatic test device that is used for the heavy caliber aqueduct comprises the main body that cooperates with the heavy caliber aqueduct, it is characterized in that: the seal pad with stiffening rib is set in the main body inner chamber, the seal pad bottom has single ring flange short tube, the short tube blind plate sealing, main body outer wall bottom, seal pad both sides are respectively established a flange and are given and stay mouth, with being connected communicating pipe, communicating pipe is provided with valve, respectively be fixed with short tube in main body outer wall top, seal pad both sides, gate is installed on the short tube.
Described seal pad is for having the sealing steel plate that " well " word supports, and the material of sealing steel plate is the A3 steel, and steel plate thickness is the 16-20 millimeter.
The present invention adopts said structure, with main body inner chamber that the heavy caliber aqueduct cooperates in be provided with have well " the sealing steel plate of word support reinforcing rib; the seal pad bottom has single ring flange short tube; the short tube blind plate sealing; main body outer wall bottom, the seal pad both sides that cooperate with the heavy caliber aqueduct are respectively established a flange and given and stay mouth; with being connected communicating pipe; communicating pipe is provided with valve, respectively be fixed with short tube in the main body outer wall top, the seal pad both sides that cooperate with the heavy caliber aqueduct, gate is installed on the short tube.Can carry out continuous hydrostatic test like this, avoid repeated labor, save cost; Pour water completely in the heavy caliber long-distance pipe hydrostatic test available water source of pouring water, the main body both sides that cooperate with the heavy caliber aqueduct utilize has single ring flange short tube, short tube replaces native backrest with the sealing steel plate with the support of " well " word of blind plate sealing, avoided non-construction quality pressure testing failure, and because the hydrostatic test water can have been avoided during water filling making troubles because of insufficient water sources with a water source, operational sequence is easy, shorten the construction period, reduced construction costs.
Describe the present invention in detail below in conjunction with drawings and Examples;
Fig. 1 shows the embodiment of the invention cut-open view of bowing;
Fig. 2 shows the A----A cut-open view of Fig. 1;
The present invention includes the main body 1 that cooperates with the heavy caliber aqueduct, the main body 1 that cooperates with the heavy caliber aqueduct, sealing steel plate 2 with " well " word support reinforcing rib is set in main body 1 inner chamber that cooperates with the heavy caliber aqueduct, the material of sealing steel plate is the A3 steel, steel plate thickness is the 16-20 millimeter, sealing steel plate 2 bottoms have single ring flange short tube 9,3 sealings of short tube 9 usefulness blind plates, the main body 1 outer wall bottom that cooperates with the heavy caliber aqueduct, seal pad 2 both sides are respectively established a flange and are given and stay mouthfuls 4, with being connected communicating pipe 5, communicating pipe 5 is provided with valve 6, the main body 1 outer wall top that is cooperating with the heavy caliber aqueduct, seal pad 2 both sides respectively are fixed with short tube 7, and gate 8 is installed on the short tube 7.
The invention process hydraulic pressure process is as follows: at first at heavy caliber aqueduct interval one km the present invention is set, close the main body 1 outer wall top that cooperates with the heavy caliber aqueduct, gate 8 on the seal pad 2 both sides short tubes 7, open the valve 6 on communicating pipe 5, close emptying valve, the water of pressure testing pipeline section is filled with through communicating pipe 5 by a water source, then, valve on communicating pipe 56 is closed, the main body 1 outer wall top that is cooperating with the heavy caliber aqueduct, the pound machine of beating is installed at gate 8 places on the seal pad 2 one side short tubes 7, the sealing steel plate 2 that utilizes " well " word support reinforcing rib is as backrest, carry out hydrostatic test, carry out next end hydrostatic test successively until whole pressure testing pipelines, realize continuous hydrostatic test; After pressure testing finishes, remove and make the pound machine, open valve 6 and draw-off valve on communicating pipe 5, the pressure testing water is discharged from draw-off valve, the part pipeline section has Yu Shui, unloads lower communicating tube 5, then, the workman enters in the main body 1 that cooperates with the heavy caliber aqueduct from flange reserved opening 4, blind plate on the short tube 93 is removed, and Yu Shui gets rid of from short tube 9, removes sealing steel plate 2, then with reserved opening 4 usefulness welding methods sealings, the main body 1 that cooperates with the heavy caliber aqueduct is stayed original position and is reached and be open to traffic.
