Description

Technical Field

[0001] The present invention belongs to the technical field of underground comprehensive pipe gallery drainage, and in particular relates to an underground comprehensive pipe gallery emergency drainage system, a remote control system and a design method. Background Art

[0002] Urban underground integrated pipe corridors refer to structures built underground in cities for the centralized laying of various municipal pipelines such as electricity, communications, water supply, drainage, heat, and gas. They can not only effectively solve the problems of disorderly urban pipelines, repeated excavation, and difficult maintenance, but also improve the utilization efficiency of urban space and beautify the urban environment. However, in the construction and operation of integrated pipe corridors, emergency drainage design is an issue that cannot be ignored. Since a variety of municipal pipelines are integrated in the pipe corridor, and the pipe corridor itself is underground, once encountering extreme weather, geological disasters or other emergencies, it is likely to cause water accumulation inside the pipe corridor, which will affect the normal operation of the pipelines in the pipe corridor and even cause safety accidents.

[0003] There are relatively few technologies for emergency drainage design of urban underground integrated pipe corridors in the existing technology, which lacks systematicness and depth. The existing management system often only considers the drainage needs under normal circumstances, but ignores the emergency drainage measures under emergencies. As a result, when encountering emergencies, the drainage system of the integrated pipe corridor often cannot meet the actual needs, which brings hidden dangers to the safe operation of the city. Therefore, it is of great significance to study a scientific and systematic calculation method and system for the emergency drainage system of the underground integrated pipe corridor to improve the safety and reliability of the pipe corridor. Summary of the invention

[0004] The purpose of the present invention is to provide an underground comprehensive pipe gallery emergency drainage system, a remote control system and a design method, aiming to solve the problem that when the existing urban underground comprehensive pipe gallery encounters an emergency, especially when the water supply pipe bursts, it will cause great safety hazards to other power supply facilities in the pipe gallery, so as to further improve the safety and reliability of the pipe gallery.

[0019] The calculation corresponding to the drainage flow rate of the water supply pipe burst is:

[0023] S3. Designing the control mode and location arrangement of the water pump under the condition of satisfying the maximum instantaneous discharge volume obtained in step S2, including controlling the operation of the water pump at different locations in the water collection well according to different water levels.

[0024] Furthermore, in the calculation of step S1, the area of ​​the tunnel opening is the sum of the areas of the pipelines exposed to the outside, including the lifting openings, ventilation openings, and entrances and exits; the empirical coefficient A is obtained based on the statistical analysis of historical rainfall data in the area where the tunnel is located, and is used to reflect the baseline value of rainfall intensity under specific conditions; the leakage amount of the tunnel is calculated by the leakage area and the leakage rate per unit area.

[0040] Among them: 1-drainage ditch, 2-collection well, 3-municipal drainage system, 4-second pump start and alarm water level, 5-first pump start water level, 6-pump stop water level, 7-ultra-low alarm water level. DETAILED DESCRIPTION

[0041] In order to better explain the content and effect of the present invention, the present invention is further described below in conjunction with the embodiments. Figure 1 :

[0042] A design method for emergency drainage of underground utility corridors first determines the types of drainage that need to be considered based on the structural characteristics and operating environment of the utility corridor, including water inflow at the corridor opening, water leakage at the corridor structure joints, flushing drainage flow in the corridor, maintenance and venting drainage flow, and drainage flow due to bursting of water supply pipes. Then, for each drainage situation, a corresponding mathematical model can be established for calculation to obtain the total drainage requirements in various situations.

[0043] Specifically, water inflow at the openings of the integrated pipe gallery includes hoisting openings, ventilation openings, entrances and exits, etc. In general, the entrances and exits and hoisting openings are usually covered after they are built. Therefore, only the water inflow of the ventilation openings needs to be calculated. For the pipe gallery openings exposed to the outside, this embodiment considers the water inflow through the rainfall intensity. The rainfall intensity is calculated as follows:

[0044]

[0045] Where: A represents the empirical coefficient, which comes from the statistical analysis of historical rainfall data in a certain area. It reflects the baseline value of rainstorm intensity under specific conditions (such as short recurrence period and short rainfall duration). Taking a city in the south as an example, the empirical coefficient is 2424.17, and another city in the south as an example, the empirical coefficient is 1600.00. q represents rainfall intensity, the unit is L / (s·hm 2 ); lgP is a logarithmic function with base 10, which is used to convert the return period from a linear scale to a logarithmic scale to better reflect the nonlinear growth trend of rainstorm intensity with increasing return period. P represents the design return period, in years; t represents the rainfall duration, in min. The coefficient 0.533 is obtained through statistical analysis and is used to adjust the impact of the logarithmic function on the growth of rainstorm intensity. (t+11) is an adjustment for the change of rainstorm intensity with rainfall duration. When the rainfall duration is short, the rainstorm intensity is often larger; when the rainfall duration is long, the rainstorm intensity tends to decrease. The t+11 here ensures that the denominator will not be zero when t=0 (that is, theoretically there is no rainfall duration), and 11 is also an empirical value used to adjust the shape of the curve. The exponent 0.668 is obtained through statistical analysis and is used to describe the attenuation rate of rainstorm intensity with rainfall duration.

[0046] Furthermore, the specific calculation method of the leakage flow rate at the structural joints of the pipe gallery is:

[0047] Q 漏 =B×q 漏

[0048] Where: Q 漏 Indicates the amount of water leakage, the unit is m 3 / s; B represents the calculated area of ​​the corridor, in m 2 ;q 漏 Indicates the average water seepage, the unit is L / (m 2 ·d), take 0.05L / (m 2 ·d). The significance of the above formula is to calculate the leakage of the pipeline corridor through the leakage area and the leakage rate per unit area. Specifically, it multiplies the leakage area by the leakage rate per unit area to obtain the total leakage of the entire leakage area.

[0049] Furthermore, the specific calculation method for flushing drainage flow in the pipe gallery is:

[0050] Refer to the road sprinkler water volume standard (2.0-3.0L / m2) to flush the pipe gallery. The single flushing water volume is calculated as follows:

[0051]

[0052] Where: Q 冲 Indicates the amount of water used for a single flushing of the pipe gallery, in m 3 / s;q 冲 Indicates the single flushing water volume, take 2.0L / m 2 C represents the area of ​​the design interval of the pipe gallery, which is also the area of ​​flushing. 3600 is a conversion factor used to convert the flushing intensity from units per hour to units per second. Because the flushing intensity is usually given in units per hour (such as m 3 / (m 2 ·h)), and what we need to calculate is the total amount of water required for a single flush, so we need to convert the time unit from hours to seconds (1 hour = 3600 seconds).

[0053] Furthermore, the specific method for draining the drainage flow rate during pipeline maintenance is as follows:

[0054] The water supply pipeline needs to be flushed and disinfected before operation or before the water supply is restored after a long-term water outage. The pipeline flushing water volume is calculated as follows:

[0055]

[0056] Where: Q 冲 Indicates the amount of water used to flush the pipe, in m 3 / s; D represents the pipe diameter in m; v represents the average pipe flushing rate in m / s, taking 1.0m / s; T represents the pipe flushing time in s. It is a constant term, which comes from the area formula of a circle A = πr 2 Since the pipe is cylindrical, its cross-sectional area (i.e. the area of ​​the circle) needs to be calculated using this formula.

[0057] Furthermore, the drainage flow calculation method of the water supply pipeline burst accident is as follows: the amount of water in the water supply pipeline burst is related to the leakage area, and the burst leakage is calculated as follows:

[0058]

[0059] Where: Q L Indicates the leakage of burst pipe, the unit is m 3 / s; A L Indicates the leakage area of ​​the explosion point, the unit is m 2 ;H L Indicates the pressure of the leak, the unit is m; g indicates the acceleration of gravity, the unit is m / s 2 The core of the above formula is Part, it represents the speed of water flowing through the rupture (or jet velocity). This speed is derived from the Bernoulli equation (a simplified form under certain conditions), which takes into account the conversion between the gravitational potential energy and kinetic energy of the water flow.

[0060] When water flows from a high-pressure area (high head) to a low-pressure area (low head or breach), its gravitational potential energy is converted into kinetic energy, causing the water flow rate to increase. L The product of the velocity of the jet gives the amount of water passing through the rupture per unit time, that is, the leakage Q L .

[0061] Finally, by adding up the flow rates calculated from the above five influencing factors, we can get the flow rate required for emergency drainage of the environmental integrated pipeline corridor. Considering the necessity and actual experience, it is necessary to multiply it by the redundancy factor of 1.2-1.5 to determine the most optimized pump type to avoid energy waste caused by excessive drainage pump power and to avoid insufficient power to meet emergency drainage needs.

[0062] In addition, combined with the drainage pump model and power obtained by this calculation method, this embodiment also provides a safe and reliable underground comprehensive pipeline corridor emergency drainage system, including a pipeline corridor structure, a drainage ditch 1, a collection well 2, a municipal drainage system 3, a second pump start-up and alarm water level 4, a first pump start-up water level 5, a pump stop water level 6 and an ultra-low alarm water level 7.

[0063] Specifically, the underground urban integrated pipe gallery is provided with a drainage ditch 1 to flow the collected water into the water collection well 2, and the bottom of the water collection well 2 has an outlet connected to the municipal drainage system 3. Four water level lines are provided on the inner side wall of the water collection well 2, which are divided into an ultra-low alarm water level 7 when the water level reaches 1 / 6 of the actual volume of the water collection well 2, a pump stop water level 6 when the water level reaches 1 / 3 of the actual volume of the water collection well 2, a first pump start water level 5 when the water level reaches 1 / 2 of the actual volume of the water collection well 2, and a second pump start and alarm water level 4 when the water level reaches 2 / 3 of the actual volume of the water collection well 2. Corresponding water level sensors are provided at the above-mentioned water levels, and the water level sensors at the first pump start water level 5 and the second pump start and alarm water level 4 are also used to control the start and stop of the water pump through the control center.

[0064] In combination with the above emergency drainage system and remote control system, the present invention can execute the following applications and emergency management plans:

[0065] (1) Assume that the maximum drainage demand of the daily drainage system of the pipeline corridor does not exceed 80m 3 / h, the water pump drainage power flow is 100m 3 / h (according to the redundancy factor of 1.2 times, it is 96m 3 / h, select the model with the flow rate that exceeds and is closest to it) to meet the daily demand of one for backup and one for use. In the event of a pipe burst, two pumps working in parallel can easily cope with the emergency drainage needs of the DN1600 pipe section (leakage surface ratio of about 1:500) and the DN1200 pipe section (leakage surface ratio of about 1:300).

[0066] In actual operation:

[0067] ① When the water level is low, the alarm is triggered and all pumps are stopped;

[0068] ②When the water level reaches the pump stop water level, both pumps stop automatically;

[0069] ③ As the water level rises to the first pump start water level, the first pump starts working;

[0070] ④ If the water level continues to rise to the second pump starting water level, the second pump will start and the system will send out an ultra-high water level alarm signal.

[0071] In this process, the selection of drainage pipe diameter is also critical. To avoid the risk of pipe bursting due to excessive flow rate, the maximum flow rate in the metal pipe should be controlled within 10m / s. Therefore, under the premise of balancing cost-effectiveness and operational safety, the pipe diameter should be carefully selected, neither too small to avoid excessive flow rate, nor too large to control costs. Therefore, the reasonable selection of pipe diameter is crucial to ensure the safety and economy of the drainage system.

[0072] (2) When the burst area increases (the ratio of the burst leakage surface to the pipe cross section is 1:100 to 1:10).

[0073] In this case, relying solely on daily drainage pumps is not enough to drain the burst water in time. It is possible to consider equipping the working section of the pipe gallery with a high-performance, large-flow emergency drainage pump, which can quickly intervene in the event of a moderate burst, effectively drain the accumulated water, and prevent key facilities such as communication cables from being submerged in water for a long time, thereby avoiding potential obstacles to use and safety risks.

[0074] In view of the ample space in the working section of the pipe gallery, an emergency drainage pump with high head and large flow is installed in the working section of the pipe gallery on both sides of the explosive point to fully meet the emergency drainage needs. For example, the working sections of the pipe gallery at both ends of the explosive pipe section are equipped with a design flow of 1000m 3 / h emergency water pump, this configuration is sufficient to cope with the emergency drainage volume of the DN1600 pipe section with a leakage ratio of about 1:50, and can also meet the drainage volume of the DN1200 pipe section with a leakage ratio of about 1:30, ensuring drainage efficiency and coverage.

[0075] In specific drainage operations, in order to efficiently utilize existing resources, the existing drainage pipe system in the corridor can be used, and a three-way interface can be set on the drainage pipe at the working section of the corridor so that when the pipe bursts, the outlet of the emergency drainage pump can be quickly connected to the drainage pipe to achieve rapid drainage.

[0076] In addition, to ensure the flexibility and efficiency of emergency drainage, each emergency water pump is equipped with a suction hose about 1,000 meters long (diameter DN400) so that it can be flexibly deployed at the pipe burst site, ensuring that the water pump can quickly and effectively absorb and discharge water from the accumulated water area, further enhancing emergency response capabilities.

[0077] (3) When the burst area is large (the ratio of the burst leakage surface to the pipe cross section is greater than 1:10).

[0078] In this case, in addition to relying on fixed emergency drainage pumps, other auxiliary drainage measures should also be considered. A simple and feasible approach is to immediately dispatch a mobile drainage vehicle to the accident site once an early warning notice of a pipe burst is received, and use its high efficiency to assist in ground drainage operations and quickly remove the accumulated water.

[0079] For example, when the mobile drainage vehicle is equipped with two units with a design flow rate of 10,000 m 3 / h drainage pump can cope with the emergency drainage volume of DN1600 pipe section with a leakage ratio of about 1:5, and can also cope with the emergency drainage volume of DN1200 pipe section with a leakage ratio of about 1:3.

[0080] Through this quick response and high-efficiency drainage measure, the time for draining accumulated water can be greatly shortened, the impact of pipe burst can be reduced, and the safety of the pipeline corridor and its internal facilities can be ensured.

[0081] Aiming at the remote control of emergency treatment, the present invention establishes a remote control system, including a control unit, a transmission module, a monitoring module, a data storage module and a water pump controller.

[0082] First of all, the data of the water level monitoring sensors arranged in the corridor are collected, connected through the transmission module, and the data is transmitted to the control unit and the remote control terminal, which are generally set up in the control room. The control unit collects the data of the water level monitoring sensors at various positions through the transmission module, including obtaining the working status of the water pump and controlling the operation of the water pump by connecting to the water pump controller, and also receives data from the monitoring module; the monitoring module includes collecting video image data in the corridor through cameras, and also includes setting up water level meters or flow meters to obtain the water inflow at the corridor opening, the leakage of the corridor, the flushing drainage in the corridor, the pipeline maintenance and drainage, and the drainage of the water supply pipeline accident; through the collection and display of data, it can provide emergency personnel with a full range of protection strategies, such as starting the water pump in advance for drainage, and arranging drainage vehicles to go to emergency pumping for emergencies.

[0083] The burst of water supply pipes in the integrated pipe gallery is characterized by strong suddenness, great harm and wide impact, but it is still not fully considered in the design of the pipe gallery. The present invention can effectively reduce the impact of sudden events such as burst of water supply pipes on the pipe gallery and urban infrastructure by comprehensively analyzing the drainage factors in the pipe gallery and designing corresponding emergency drainage measures and pipe burst emergency plans, thereby improving the safety and reliability of the operation of the pipe gallery.

[0084] The calculation method and system of the underground integrated pipe gallery emergency drainage system provided by the present invention fully considers various drainage conditions of the pipe gallery, obtains the total drainage volume through a scientific calculation method, and designs an efficient and reliable emergency drainage system based on this. The system can quickly respond to emergencies such as bursts of water supply pipes, reduce the impact on the safe operation of the pipe gallery, and improve the reliability and safety of urban infrastructure.
