Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of underground drainage systems in municipal engineering, and specifically relates to an underground drainage system for municipal roads and a construction method. BACKGROUND

[0002] Municipal engineering is an important part of urban infrastructure, covering roads, bridges, pipelines and other facilities. Among them, the underground drainage system is a key facility to ensure that urban roads avoid water accumulation during rainfall. Traditional drainage systems usually use simple drainage ditches or pipeline designs, but in extreme weather conditions, such as continuous rainfall, their drainage capacity is often insufficient, leading to road waterlogging and affecting traffic and people's lives. With the acceleration of urbanization, the efficiency and reliability of drainage systems are increasingly demanding, and it is urgent to improve existing technologies to cope with more complex drainage needs.

[0003] Currently, municipal road drainage systems mainly use the following methods: 1) open ditch drainage, which sets drainage ditches on both sides of the road to guide rainwater to the collection well through gravity; 2) underground pipe drainage, which buries drainage pipes underground to transport rainwater to sewage treatment facilities or natural water bodies through pipes; 3) combined drainage, which combines the advantages of open ditch and underground pipe, sets a collection well at the low-lying place of the road, and then discharges through pipes. Open ditch drainage is simple to construct, but it is easy to be blocked by debris and has poor aesthetics. Underground pipe drainage is well hidden, but it is difficult to maintain and has high cost. Combined drainage combines the advantages of the first two, but it may still have insufficient drainage capacity during continuous rainfall.

[0004] The main defects of the above-mentioned existing drainage systems include: (1) limited drainage capacity, especially during continuous rainfall, which can easily lead to road waterlogging; (2) simple design, lacking adaptability to complex weather conditions; (3) difficult to maintain, especially for underground pipe drainage systems, which are difficult to quickly unblock after being blocked; (4) high construction cost, especially for combined drainage systems, which require a large amount of materials and labor input, so it needs to be improved.

Detailed Implementation

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 6 As shown, the present invention provides an underground drainage system for a municipal road, including a road soil body 1, a drainage ditch assembly 2 laid on both sides of the road soil body 1; a water collection well assembly 3 disposed at the corresponding ends of the drainage ditch assembly 2; and a pipe assembly 4 disposed at the corresponding bottom end of the water collection well assembly 3. The drainage ditch assembly 2 includes a main drainage ditch 201 laid with grooves on both sides of the road soil body 1, and an auxiliary drainage ditch 202 disposed vertically in the main drainage ditch 201. The water collection well assembly 3 includes a main water collection well 301 and an auxiliary water collection well 302 disposed at the ends of the main drainage ditch 201 and the auxiliary drainage ditch 202, respectively. The pipe assembly 4 includes a main pipe 401 and an auxiliary pipe 402 disposed at the bottom ends of the main water collection well 301 and the auxiliary water collection well 302, respectively.

[0022] After rainwater is filtered through the filter assembly 6 into the main drainage ditch 201 and the auxiliary drainage ditch 202, it will slowly flow into the corresponding main collection well 301 and auxiliary collection well 302, and finally be discharged smoothly through the corresponding main pipe 401 and auxiliary pipe 402.

[0023] like Figure 5 As shown, the auxiliary drainage ditch 202 adopts a slope design.

[0024] The above scheme is adopted because the auxiliary drainage ditch 202 has a certain slope design, so that some of the water flowing inside the main drainage ditch 201 can enter the auxiliary drainage ditch 202 and be smoothly concentrated and guided into the auxiliary water collection well 302.

[0025] like Figures 1 to 3As shown, the top end of the main drainage ditch 201 is provided with a main drainage ditch baffle 5, and the inside of the main drainage ditch baffle 5 is provided with a filter assembly 6.

[0026] With the above scheme: through the design of the main drainage ditch baffle 5, large blocks can be blocked, and the filter screen 602 is prevented from being damaged by falling. It should be noted that the length of the main drainage ditch 201 is designed according to the specific construction condition, and therefore the number of the main drainage ditch baffles 5 is also designed according to the condition.

[0027] As shown in the drawings, Figure 3 The filter assembly 6 includes a limiting block 601, a filter screen 602, an elastic assembly 603, and a blocking block 604. The limiting block 601 is arranged at the bottom surface of the top end of the main drainage ditch 201, the filter screen 602 is movably sleeved in the inside of the main drainage ditch baffle 5, and the inner end of the filter screen 602 is slidably connected with the outer end of the limiting block 601. The elastic assembly 603 is arranged at the outer end of the limiting block 601 and below the end portion of the limiting block 601, and the blocking block 604 is arranged at the outer end of the limiting block 601 and above the end portion of the filter screen 602.

[0028] With the above scheme: through the design of the limiting block 601, the deflection of the filter screen 602 can be limited in sliding.

[0029] As shown in the drawings, Figure 4 The elastic assembly 603 includes a fixed seat 6031, an air bag strip 6032, and a top block 6033. The fixed seat 6031 is arranged at the bottom of the inner end of the limiting block 601, the air bag strip 6032 is arranged in the inside of the fixed seat 6031, and the top block 6033 is movably installed in the inside of the fixed seat 6031 and below the air bag strip 6032. The end portion of the air bag strip 6032 is designed with rubber.

[0030] With the above scheme: due to the soft material design of the air bag strip 6032, damage to the filter screen 602 caused by impact can be avoided.

[0031] As shown in the drawings, Figure 4 The air bag strip 6032 is made of rubber.

[0032] With the above scheme: due to the strong deformation and stretching ability of rubber, the air bag strip 6032 can be smoothly pushed and retracted.

[0033] As shown in the drawings, Figure 2 The main drainage ditch baffle 5 is provided with a impurity collection assembly 7, and the impurity collection assembly 7 includes a mounting cover plate 701, an impurity collection frame 702, and a buckle groove 703. The installation cover plate 701 is movably installed between the main drainage ditch baffle 5, the impurity collecting frame 702 is arranged at the bottom of the installation cover plate 701, and the buckle groove 703 is arranged at the top of the installation cover plate 701.

[0034] By adopting the above scheme, when the filter screen plate 602 is deflected, the impurities can be guided to move to the inside of the impurity collecting frame 702.

[0035] As shown in Figure 2 The installation cover plate 701 and the impurity collecting frame 702 are installed in a clamped manner.

[0036] By adopting the above scheme, after the installation cover plate 701 and the impurity collecting frame 702 are taken out, the installation cover plate 701 can be opened to clean the impurities in the impurity collecting frame 702.

[0037] As shown in Figure 2 The inner wall of the buckle groove 703 is rough.

[0038] By adopting the above scheme, the installation cover plate 701 and the impurity collecting frame 702 can be smoothly buckled from the main drainage ditch baffle 5.

[0039] A construction method of a municipal road underground drainage system, the construction method is as follows: S1: survey the terrain before construction, determine the positions of the drainage ditch assembly 2 and the water collecting well assembly 3; S2: excavate a trench, install the main drainage ditch 201 and the auxiliary drainage ditch 202, and ensure that the slope is directed to the water collecting well assembly 3; S3: pour the water collecting well assembly 3 foundation, and install the water collecting well assembly 3; S4: lay the pipeline assembly 4, and connect the water collecting well assembly 3 and the water outlet; S5: backfill the earthwork, and compact the pavement.

[0040] The working principle and use process of the present application are as follows: Firstly, when rainwater enters the top of the filter screen plate 602 through the limiting block 601, the filter screen plate 602 is deflected to one side under the pressure of the rainwater and the gravity of the impurities, and the air bag strip 6032 is retracted into the fixed seat 6031, so that the air bag strip 6032 is compressed, then when the water pressure becomes small, the elastic force of the air bag strip 6032 is released, the fixed seat 6031 is pushed against the filter screen plate 602, and the filter screen plate 602 is deflected and opened instantaneously, so that the impurities on the top of the filter screen plate 602 are shaken to the outside and flow into the inside of the installation cover plate 701 to accumulate, and the top of the filter screen plate 602 is prevented from being blocked.

[0041] Then the rainwater will fall through to the inside of the main drain 201, and part of the water flow will enter the inside of the auxiliary drain 202, and the water flow in the main drain 201 will flow to the inside of the main water collecting well 301, and the water in the auxiliary drain 202 will flow to the inside of the auxiliary water collecting well 302, and then the water in the main water collecting well 301 and the auxiliary water collecting well 302 will be discharged to the sewage treatment equipment and the natural water body through the main pipe 401 and the auxiliary pipe 402 respectively, realizing the smooth and concentrated discharge of rainwater, and the additional drainage path design of the main drain 201 and the auxiliary drain 202 can greatly improve the drainage efficiency to deal with the situation of excessive rainwater and water accumulation in bad weather.
