Abstract

The invention mainly relates to a closed type double-layer capsule solanum torvum bunge, wherein one capsule is arranged inside and is called an inner capsule, and the other capsule is arranged outside and is called an outer capsule, and the capsule is provided with a mouth (water injection mouth) capable of being filled with liquid. When in use, the saline is firstly added into the inner capsule, so that the capsule sinks to the bottom of the well. When the capsule reaches the bottom of the well, salt water is continuously filled into the inner capsule, so that the inner capsule expands to greatly occupy the volume of the water well, and when the water well is full of the capsule, the water can be cut off initially. At the moment, the inner capsule is sealed, and then water is injected into the outer capsule, so that the water pressure of the outer capsule is greater than that of the inner capsule, the pipe diameter of the inner capsule is reduced, and the outer capsule occupies the well volume. When the pressure difference between the water in the capsule and the water in the pipeline reaches a safe value. The pipeline to be repaired can be pumped and then the well can be operated.

Description

Water eggplant

(I) the technical field

The product is about pipeline plugging, and research is carried out to solve the risk of frogman working under water well. The urban sewage pipeline maintenance device is mainly applied to maintenance of urban sewage pipelines, reduces risks of personnel construction, and improves work efficiency.

(II) background of the invention

The current drainage pipeline cleaning construction scheme is that a water pump is adopted for drainage and precipitation at first. Then, the construction work can be performed. When the water level drops, workers go down the well and use the high-pressure air bag to plug the sewage pipeline. To being difficult to use the water pump to carry out drainage, precipitation, can adopt frogman to go into the well and operate, use high-pressure air bag to carry out the shutoff to the sewer line. The method of using frogman to go into well has certain risk. The air bag is plugged underwater, the plugging process time is short, the effect is quick, the safety risk is high, and the air bag is easy to explode and can bring life danger to constructors.

Disclosure of the invention

The technical principle is as follows: the liquid bag is used as plugging equipment, the purpose of plugging an underwater pipeline is achieved by utilizing the water pressure difference, and when the water pressure in the liquid bag is greater than the water pressure in a well, the liquid bag is outwards expanded, so that the opening of the underwater pipeline can be plugged. So that people can plug the underground pipeline under the condition of not going into the well. The air bags cannot be made due to buoyancy, and although only a small change, completely different effects can be produced. For example, saline water is used as filling liquid, and the saline water bag can naturally sink from the wellhead to the bottom of the well by using the self-weight of the saline water due to the fact that the density of the saline water is larger than that of water. When the saline water sac reaches the bottom of the well, saline water is continuously filled into the saline water sac, so that the saline water sac expands and greatly occupies the volume of the well, and when the volume of the saline water sac is full of the well, the water can be cut off preliminarily. At the moment, brine is further filled, so that the water level in the brine bag is raised, at the moment, the brine bag is expanded because the water pressure is higher than the water pressure in the pipeline, and when a certain water pressure difference is reached, the opening of the pipeline is blocked, so that the sewage well is thoroughly blocked. As long as the water pressure in the pipeline is less than that of the saline water bag, the water in the pipeline cannot flow out, and therefore the purpose of plugging is achieved.

Due to the use of single layer capsules, there may be a risk of capsule rupture, posing a certain threat to the safety of downhole personnel. Thus an improvement is made to a product having two capsules (as shown in fig. 1), one inside, called the inner capsule, and one outside, called the outer capsule. The capsule is provided with a liquid-filling opening (water filling opening), and the inner and outer capsules are provided with filling openings. When in use, saline is firstly filled into the inner capsule (if the saline is not used, a part of weight can be added into the capsule), so that the capsule is sunk to the bottom of the well. When the capsule reaches the bottom of the well, saline water is continuously filled into the inner capsule, so that the inner capsule expands to greatly occupy the volume of the water well, and when the water well is full of the volume of the capsule, the water can be cut off preliminarily. At the moment, the inner capsule is sealed, and then water is injected into the outer capsule, so that the water pressure of the outer capsule is greater than that of the inner capsule, the pipe diameter of the inner capsule is reduced (the original pipe diameter of the inner capsule is the diameter of the well), the water level in the inner capsule rises, and the outer capsule occupies the volume in the well. When the pressure difference between the water pressure in the capsule and the water in the pipeline reaches a safe value. The pipeline to be repaired can be pumped, and as shown in fig. 3, when the upper well and the lower well of the well area to be repaired are pumped with water, personnel can go into the well for operation. The benefit of the dual capsule is its safety, such as sudden outer capsule rupture, liquid in the capsule flowing out, and water pressure drop. At the moment, the inner capsule can automatically fill the volume of the outer capsule in the well due to the existence of pressure difference, so that the pipeline is guaranteed to be continuously blocked. And the safety threat to the downhole operation workers can not be generated.

If three or more capsules are used, although the safety can be improved, the cost is also increased, the operation complexity is increased, and the cost performance is reduced. The filling port of the capsule can also be provided with a gas filling valve which can be used for pressurizing after water is filled.

A simplified product can also be used, being a product with two non-closed capsules (as shown in fig. 2), one inside, called non-closed inner capsule, and one outside, called non-closed outer capsule. The simplified product can only be used when the water level in the well is low, or a circular tube is erected at the well mouth for fixing the bag mouth of the non-closed capsule during use. Similarly, when in use, the saline is firstly added into the inner capsule, so that the capsule sinks to directly reach the bottom of the well. When the capsule reaches the bottom of the well, salt water is continuously filled into the inner capsule, so that the inner capsule expands to greatly occupy the volume of the water well, and when the water well is full of the capsule, the water can be cut off initially. At the moment, the inner capsule is sealed, and then water is injected into the outer capsule, so that the water pressure of the outer capsule is greater than that of the inner capsule, the pipe diameter of the inner capsule is reduced, the water level in the inner capsule rises, and the outer capsule occupies the volume in the well. When the pressure difference between the water in the capsule and the water in the pipeline reaches a safe value. As shown in figure 4, the pipeline to be repaired can be pumped, and after the water is pumped out, personnel can go into the well for operation.

Fig. 5 shows a design of a sewage pipe network, which is called herein a distributed curved branch network, and is a sewage pipe network formed by three stages of curved branch pipes. The sewage wells are connected by straight pipes with the sewage wells as break points, and the sewage wells are named as curved branch pipes due to the adoption of a broken line connection mode. The house-entering sewage pipe is directly connected to a sewage well (a vertical well) on the first-stage curved branch pipe network; the pipe diameter of the second-stage curved branch pipe is larger than that of the first-stage curved branch pipe, the pipeline burial depth is also deeper than that of the first-stage curved branch pipe, and the second-stage curved branch pipe is used for collecting sewage collected by the first-stage curved branch pipe network; the third-stage curved branch pipe is larger than the second-stage curved branch pipe in pipe diameter, and the buried depth of the pipeline is deeper than that of the second-stage curved branch pipe and is used for being connected with a sewage treatment plant. Fig. 6 is another perspective view of the distributed meander network of fig. 5. Fig. 7 is a side view of the distributed meander network, and it can be seen that fig. 7 is similar to fig. 9. Fig. 8 is a top view of a distributed meander network, the planar arrangement of which can be seen.

The curved branch pipe shown in fig. 9 is composed of a broken line pipe and a solid well. Two adjacent vertical wells are connected by a straight pipe according to a certain slope. Because the two wells are close to each other, the slope can be increased to ensure that the interior of the straight pipe is not blocked. The slope of the first stage curved branch can be selected to be 1%, and the slope of the second stage curved branch and the third stage curved branch can be selected to be 2-3%. The pipe diameter of the first-stage curved branch pipe can be 300mm to 400mm, the pipe diameter of the second-stage curved branch pipe can be 600mm to 800mm, and the pipe diameter of the third-stage curved branch pipe can be 1500mm to 1800mm. The site selection of the sewage treatment plant can be selected at the side of the third-stage curved branch pipe, so that the site selection range of the sewage treatment plant is enlarged.

The distributed curved branch network has the advantages that 1, the pipeline is convenient to maintain and update, and local updating and maintenance can be performed on the premise of ensuring the use function of the sewage pipe network. When the pipeline is updated and maintained, the life of residents is not greatly influenced, and the adverse effect is minimized. Meanwhile, the sewage pipe network is not influenced to continuously collect sewage, so that the environment is protected. 2. Standardized and modularized components are adopted, and construction is facilitated. 3. The network management layout is flexible, the adaptability is strong, and the fault-tolerant rate is high. 4 the shared pipeline water passing area can be managed in the pipeline drainage in the pipe network, the drainage ability of the pipe network is effectively improved, and the fault-tolerant rate is improved. 5. The pipe network can be built and updated in stages, and the scale of one-time investment is reduced. 6. The site selection of the sewage treatment plant becomes convenient and flexible, and the selectable positions are more. And simultaneously, the sharing of the sewage treatment capacity of a plurality of sewage treatment plants can be realized.

The distributed bent branch net can be effectively combined with the water eggplants to carry out local updating and reconstruction. As shown in fig. 10, it can be seen that 8 solanum torvum were used to enclose a pipe renewal area. The enclosed pipeline updating area can be updated or maintained, and other pipe networks are still communicated with each other and can be used as usual. The hatched area of the sewage treatment plant is the site selection area as shown in fig. 10, and is located on the side of the third-stage curved branch pipe. The shaded areas are usually located in urban areas and the land prices are relatively low.

The storm sewer network may also be made with reference to a distributed meander network. The rainwater pipes on the road can be arranged on the isolation belt in the middle of the road, the two sides of the road are high, the middle of the road is low, and rainwater on the road can be collected into the rainwater pipes in the middle. The inconvenience brought to the pedestrians by the road ponding can be solved. The afforestation of median can sink, reduces the raise dust, absorbs more rainwater simultaneously.
