Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipeline support, in particular to an adjustable pipeline support device for water conservancy projects. BACKGROUND

[0002] Water conservancy project is an engineering for controlling and allocating surface water and groundwater in nature to achieve the purpose of eliminating harm and benefiting, also known as water project, and is built to control water flow, prevent flood disasters, and regulate and distribute water to meet the needs of people's life and production for water resources. The water conservancy project has a requirement for water intake guarantee rate in specific implementation, so the river water intake port needs to be set below the low water level in the dry season to ensure stable water intake. When the single-span length of the water intake pipe is large, a concrete support pier (or a pier) is added in the middle to divide the water intake pipe into multiple spans to reduce the single-span length. The above technical means is relatively easy to implement for water intake pipes with high elevation, outer beach, and gentle outer slope at the embankment (the water pipe can enter the water relatively gently, and the intermediate support pier or pier can be constructed on the dry outer beach during the dry season); however, it is difficult to implement for water intake pipes with low elevation, no outer beach, and steep outer slope at the embankment. The position of the support pier or pier may be below the water surface all year round, so a cofferdam needs to be built for dry construction, resulting in large construction investment, and the cost of building a cofferdam is much higher than that of building a pier or support pier. To solve the above problems, the present application provides an adjustable pipeline support device for water conservancy projects. SUMMARY

The interference rod 52 is arranged between the limiting ring 51 and the positioning ring 54. The positioning ring 54 is penetrated by a through hole with a size and number that is compatible with the interference rod 52. The clamping block 55 is clamped on the outer surface of the limiting ring 51 at one end away from the positioning ring 54, and the weight of the clamping block 55 close to the positioning ring 54 is greater than that of the clamping block 55 close to the limiting ring 51.

[0028] The working process and principle of the above embodiment are as follows: Forming of bagged concrete slope protection 11: It should be noted that the adjustable pipeline support device for water conservancy projects is specifically used for constructing a water intake pipe on a dike slope without an outer beach and with a relatively steep outer slope. In order to reduce the impact of the newly built project on the original dike slope, the staff needs to perform slope trimming and reinforcement on the steep and uneven dike slope by using concrete, so as to form a surface flatness of the formwork concrete slope 11. Installation of the device: The staff transports metal pieces such as leveling H-beams 21, limiting angle steels 23, and track channel steels 24 to the concrete dike slope by using the external device, places the leveling H-beams 21 at the specified positions according to the pre-calculated data, and makes the leveling H-beams 21 parallel to the inclined plane of the formwork concrete slope 11. Then, the expansion anchors 22 are installed equidistantly in the leveling H-beams 21 by using a drilling tool. It should be noted that, in order to ensure that the expansion anchors 22 can stably fix the leveling H-beams 21, the bottom end of the expansion anchors 22 needs to be located in the formwork concrete slope 11, and the top end of the expansion anchors 22 needs to be immersed in the leveling H-beams 21. Then, the limiting angle steels 23 are fixedly installed on the upper surface of the installed leveling H-beams 21, and the limiting angle steels 23 are fixedly installed with the leveling H-beams 21 by using bolts. This process needs to ensure that the two limiting angle steels 23 on the two leveling H-beams 21 are arranged in axial symmetry. After installation is completed, two track channel steels 24 are placed between the left and right limiting angle steels 23, and the track channel steels 24 are welded with the leveling H-beams 21 and the limiting angle steels 23. It should be noted that, since the length of the formwork concrete slope 11 needs to be trimmed according to the size of the dike slope, the length of the formwork concrete slope 11 is not uniform. Under the limitation of the existing fixed-size track channel steels 24, the track channel steels 24 need to be arranged in multiple sections according to the above steps, and the adjacent two sections of the track channel steels 24 are welded with each other, and it needs to be ensured that the multiple sections of the track channel steels 24 are kept in parallel with the inclined plane of the formwork concrete slope 11. After the multiple sections of the track channel steels 24 are welded, the outer surface of the track channel steel 24 located at the last section of the track channel steels 24, i.e., located at the bottom end of the inclined plane of the formwork concrete slope 11, is welded with the continuous beam channel steel 26 to fix the position of the last end track channel steel 24. In addition, multiple clamping plates 27 are welded on the outer surfaces of the continuous beam channel steel 26 and the track channel steels 24 after welding is completed. It should be noted that the continuous beam channel steel 26 and the multiple clamping plates 27 jointly constitute a box-type clamping device, the end of the clamping device is welded with a steel pipe pile 28, and the bottom end of the steel pipe pile 28 penetrates through the formwork concrete slope 11 and extends into the soil layer, so as to further fix the position of the last end track channel steel 24, thereby forming a stable track for the movement of the water conveying pipe 31. It should be noted that, in order to ensure that the water conveying pipe 31 can be quickly placed inside the track channel steel 24, the first section of the track channel steel 24 symmetrically arranged in the vertical direction is located on the upper edge of the one end of the highest position of the bagged concrete slope 11, and the size of the water conveying pipe 31 needs to be cut. At the same time, the box type clamping device composed of the continuous beam channel steel 26 and the clamping plate 27 is welded on the steel pipe pile 28, which can transmit the horizontal component force of the whole structure to the steel pipe pile 28, thereby reducing the horizontal stress of the conveying track formed by the track channel steel 24, and avoiding stress concentration; Through the arrangement of the track channel steel 24, the steel pipe pile 28, the continuous beam channel steel 26 and the clamping plate 27, the sliding rail formed by the track channel steel 24 can be fixed at the end of the sliding rail, thereby reducing the setting of the abutment and infrastructure along the shore of the bagged concrete slope 11, reducing the requirement for the soil quality of the shore slope, and having a wide application range and ensuring the stability of the sliding rail; Subsequently, the workers can place the multi-section water conveying pipe 31 and the water pump 32 into the conveying track formed by the track channel steel 24. It should be noted that, in order to adapt to the size of the bagged concrete slope 11, the water conveying pipe 31 and the water pump 32 are arranged in multiple sections, and in order to enable the water conveying pipe 31 and the water pump 32 to slide inside the track channel steel 24, the first end water conveying pipe 31 and the water pump 32 connected thereto are arranged as a group, and the multiple groups of water conveying pipes 31 are sequentially arranged in the above order; Through the arrangement of the multiple water conveying pipes 31 and the multiple water pumps 32, the original long pipeline is segmented, which is convenient for adjusting the water inlet elevation of the water pump 32 according to actual needs. In addition, the water conveying pipe 31 can be installed and recycled on the bagged concrete slope 11 in a sliding manner, reducing the underwater work of the workers during installation and recycling, thereby reducing the difficulty of installation, maintenance and pipeline maintenance; Before placing the water conveying pipe 31 and the water pump 32 inside the track channel steel 24, the workers need to weld support angle steels 41 and support channel steels 42 at both ends of each group of water conveying pipes 31 and water pumps 32, respectively, that is, two groups of support angle steels 41 are located at the ends of the water conveying pipe 31 and the water pump 32 away from each other. Subsequently, the support angle steels 41 and the support channel steels 42 are welded together through the tie rod angle steel 43, and the stability of the support angle steels 41 and the support channel steels 42 supporting the water conveying pipe 31 and the water pump 32 is improved through the tie rod angle steel 43; Subsequently, the ends of the support angle steels 41 and the support channel steels 42 are welded with the connecting angle steel 44, and the slide block 45 is fixed and installed on the bottom surface of the connecting angle steel 44 through bolts, so that the bottom surface of the slide block 45 is in contact with the inner surfaces of the two track channel steels 24, and the multiple water conveying pipes 31 and the water pump 32 can stably slide inside the track channel steel 24; At the same time, when the slider 45 slides inside the track channel steel 24, the stopper 46 provided on the slider 45 also slides with it, and during the sliding process, the baffle 1 47 and the baffle 2 48 assist, so that the slider 45 can slide stably; During the above process, due to the symmetrical arrangement of the support channel steel 42, the support angle steel 41, the connecting angle steel 44 and the slider 45 at both ends of each set of water delivery pipes 31 and water pumps 32, the multiple sections of water delivery pipes 31 and water pumps 32 in the track channel steel 24 can all remain in a horizontal state and can slide within the movable track formed by the multiple sections of track channel steel 24; After the first section of the water delivery pipe 31 and the water pump 32 are installed, the staff needs to assemble multiple sections of the water delivery pipe 31 to form a stable water vapor delivery channel in the track channel steel 24. Therefore, the ports of two adjacent groups of water delivery pipes 31 and water pumps 32 need to be fixed and installed; It should be noted that, referring to Figure 1 The water vapor delivery pipeline composed of the leveling I-steel 21, the water delivery pipe 31 and the water pump 32 can be provided with multiple groups according to the needs of the project; In the prior art, bolts and other fixing methods are often used to install the ports of the two groups of water delivery pipes 31, which takes a lot of time to install and disassemble. Therefore, when the above device installs the two adjacent groups of water delivery pipes 31, the limiting ring 51 fixedly installed on the outer surface of the water delivery pipe 31 will move toward the positioning ring 54 fixedly connected to the outer surface of the port of the adjacent water delivery pipe 31. At this time, the interference rods 52 fixedly connected to the outer surface of the limiting ring 51 in a circular array will move toward the positioning ring 54, so that the interference rods 52 are inserted into the through grooves provided in the positioning ring 54 until the end of the interference rod 52 away from the limiting ring 51 contacts the outer surface of the clamping block 55. During the above process, the limit spring 53 sleeved on the outer surface of the contact rod 52 is squeezed by the limit ring 51 and the positioning ring 54 and is in a compressed state. Moreover, since the weight of the clamping block 55 near the positioning ring 54 is greater than that of the clamping block 55 near the limit ring 51, in the initial state of the clamping block 55, the end thereof near the positioning ring 54 rotates with the rotation connection point between the clamping block 55 and the positioning ring 54 as the fulcrum, thereby presenting a state in which one end is higher than the other end. As the interfering rod 52 and the clamping block 55 come into contact with one end of the positioning ring 54, the clamping block 55 will deflect with its connection point with the positioning ring 54 as a fulcrum, so that its other end approaches the direction of the limiting ring 51. The above process continues as the water delivery pipe 31 is inserted into the water pump 32 until the clamping block 55 is engaged with the limiting ring 51, fixing the position of the limiting ring 51. In this way, the two sets of adjacent water delivery pipes 31 and the ends of the water pump 32 are fixedly installed by the limiting ring 51, the clamping block 55 and the positioning ring 54. It should be noted that the connection between the delivery water pipe 31 and the water pump 32 and the sealing ring provided between the adjacent delivery water pipes 31 are all prior art, so here is not much redundant.

[0029] By limiting the ring 51, the contact round rod 52, the positioning ring 54 and the clamping block 55, the adjacent delivery water pipe 31 and the water pump 32 can be quickly connected, and the two can be quickly disassembled under the condition of stable connection, thereby shortening the maintenance time of the delivery water pipe 31 during maintenance; After the multi-section delivery water pipe 31 and the water pump 32 are installed, the worker installs the butterfly valve 33 in the last delivery water pipe 31, and installs the telescopic pipe 34 away from the inside of the delivery water pipe 31, which is convenient for adjusting the length of the whole pipe. After installation, the other end of the telescopic pipe 34 is fixedly installed with the connecting pipe 39, and the connecting pipe 39 is arranged to fit the surface of the mold bag concrete slope 11. Finally, the end of the connecting pipe 39 away from the telescopic pipe 34 is buried in the grounding pipe after being erected across the river. It should be noted that the height of the pipe bottom of the connecting pipe 39 needs to be higher than the highest water level of the river; At the same time, in the above process, the worker needs to install the breathing valve 36 on the outer surface of the connecting pipe 39, and install the diaphragm reinforced concrete pipe 35 between the telescopic pipe 34 and the breathing valve 36 outside the connecting pipe 39, and fix the diaphragm reinforced concrete pipe 35 with the mold bag concrete slope 11. Then, the reinforced concrete pier 38 is fixedly installed at the end of the connecting pipe 39, and the reinforced concrete pier 38 is fixedly installed with the mold bag concrete slope 11. Then, the buried reinforced concrete pipe 37 is fixedly installed between the reinforced concrete pier 38 and the breathing valve 36 outside the connecting pipe 39, and the buried reinforced concrete pipe 37 is fixedly installed with the mold bag concrete slope 11; In the above device, the worker opens the breathing valve 36 and the butterfly valve 33, and transports the water flow in the river through the multiple water pumps 32, multiple delivery pipes and connecting pipes 39; In order to facilitate the subsequent maintenance of the water pump 32 and the delivery pipe, after the connection between one of the delivery pipes connected with the connecting pipe 39 is removed, the delivery pipe and the water pump 32 can be removed from the inside of the rail channel steel 24 by the external lifting machine. Since the delivery pipe and the water pump 32 are provided in multiple groups, each group of delivery pipe and water pump 32 can be directly disassembled and maintained after being pulled out of the rail channel steel 24.
