Description

Technical Field

[0001] The present invention relates to the technical field of construction joints, and particularly to a construction device and method for construction joints of basement connecting passages. Background Art

[0002] The basement connecting passage is built underground and is used to connect passages between various office buildings, complexes and other buildings, allowing pedestrians to freely shuttle between buildings without being affected by ground traffic flow, truly realizing the separation of people and vehicles and being unimpeded by wind and rain. The construction joint of the basement connecting passage is a special structure in the building structure. The construction joint can cope with the expansion and contraction deformation of the building caused by factors such as weather changes and earthquakes, ensuring the stability of the building structure; at the same time, the construction joint can also separate the deformation between different materials, avoiding damage caused by the transmission of acting forces; in addition, the construction joint can also reduce the vibration of the building during an earthquake and reduce the impact of the building on the foundation, thereby protecting the stability of the foundation.

[0003] When performing waterproof construction on the construction joint, it is necessary to clean the inside of the construction joint. However, since the width of the construction joint is generally about a few centimeters, a high-pressure water gun is usually used for cleaning. When cleaning the construction joints on the top plate and side walls of the basement connecting passage, the water sprayed from the inside of the construction joint will splash on the workers. When cleaning the construction joint on the bottom plate of the basement connecting passage, some impurities will precipitate on the surface of the water stop rubber plate, and the width of the construction joint is small, and the high-pressure water gun cannot evenly wash the concrete surfaces on both sides of the construction joint, resulting in unclean cleaning of the inside of the construction joint, affecting the stress and deformation of the building, and when laying waterproof materials inside the construction joint, the impurities affect the sealing effect between the waterproof material and the concrete, reducing the waterproof effect of the construction joint.

[0004] Therefore, it is necessary to provide a new construction device and method for construction joints of basement connecting passages to solve the above technical problems. Summary of the Invention

The high - pressure water pump is connected to the support pipe through a first connecting pipe, and one end of the connecting plates on both sides of the support pipe is in a semi - circular structure, and the inside of the elastic connecting plate is hollow and in a "V" - shaped structure.

[0012] Preferably, the interior of the flushing pipe is threadedly connected to a screw plug, and the screw plug is slidably connected to the side wall of the second nozzle; the interior of the screw plug engages and rotates to connect a hose, and a fixed pipe is installed at one end of the hose; the fixed pipe is threadedly connected to the second joint.

[0015] A construction method for a basement connecting passage deformation joint specifically comprises the following steps: Step 1: insert the elastic filter net between the two fixing plates, the elastic filter net presses the fixing plates outwards, so that the two elastic fixing plates are stretched outwards; and fix the joint on the surface of the fixing plates by a limiting mechanism; Step 2: During the process of placing the fixing plate into the deformation joint, the elastic filter presses the fixing plate and the rubber pad outward, so that the rubber pad is closely attached to the surface of the concrete, thereby increasing the sealing between the two and preventing water from leaking from the gap between the rubber pad and the concrete; Step three: when cleaning the side walls of the deformation joint and the side walls of the rubber waterstop plate at the same time, the fixed plate slides inside the deformation joint, and high-pressure water is sprayed out obliquely through the second nozzle to wash the surface of the concrete, so as to clean the surface of the concrete; due to the obstruction of the rubber pad, the water and impurities for washing the concrete remain inside the fixed plate, and the water inside the fixed plate is sprayed obliquely toward the surface of the rubber waterstop plate through the washing pipe to wash the surface of the rubber waterstop plate, and at the same time, the two streams of water collide with each other on the surface of the rubber waterstop plate and move toward the direction of the first joint.

Detailed implementation manners

[0019] The present invention will be further described below in conjunction with the accompanying drawings and implementation manners.

[0020] Please refer to Figures 1 to 11 , Figure 1 which is a schematic structural view of a preferred embodiment of the basement connecting passage deformation joint construction device and method provided by the present invention; Figure 2 is Figure 1 Schematic enlarged view of the structure at location A shown;Figure 3 for Figure 2 An enlarged schematic diagram of the structure at B shown; Figure 4 for Figure 3 An enlarged schematic diagram of the structure at position C is shown; Figure 5 for Figure 3 The internal structure diagram of the fixed plate shown; Figure 6 for Figure 3 The schematic diagram of the fixed plate structure shown; Figure 7 for Figure 3 A top view of the internal structure of the fixing plate shown; Figure 8 for Figure 3 A top view of the bottom structure of the fixed plate shown; Figure 9 for Figure 1 A schematic diagram of the internal structure of the top plate shown; Figure 10 for Figure 9 An enlarged schematic diagram of the structure at D shown; Figure 11 for Figure 3 The elastic filter structure diagram shown in the figure. The basement connecting passage deformation joint construction device includes: an extraction mechanism 3, the extraction mechanism 3 is slidably connected to the inside of the deformation joint 23, the extraction mechanism 3 includes an elastic filter 35, the two ends of the elastic filter 35 are respectively fixedly connected to the first joint 34 and the second joint 36, the elastic filter 35 and the second joint 36 are slidably connected to the side wall of the elastic fixed plate 62; before use, the second joint 36 and the elastic filter 35 are inserted between the two fixed plates 62, and as the elastic filter 35 enters, the elastic filter 35 presses the fixed plate 62 outward, so that the two elastic fixed plates 62 are The fixed plate 62 is stretched outward to increase the distance between the two fixed plates 62. When the fixed plate 62 is placed in the deformation joint 23, the fixed plate 62 contracts inward to squeeze the elastic filter 35, and at the same time, the elastic filter 35 squeezes the fixed plate 62 outward to fix the fixed plate 62 inside the deformation joint 23. When the fixed plate 62 slides inside the deformation joint 23, the elastic filter 35 squeezes the fixed plate 62 and the rubber pad 61 outward, thereby increasing the sealing between the rubber pad 61 and the concrete, preventing water from leaking from the gap between the fixed plate 62 and the concrete, and avoiding water splashing.

[0021] The limiting mechanism 5 includes a mounting pipe 51 and a clamping groove 55. The side walls of the first joint 34 and the second joint 36 are provided with the annular clamping groove 55. The mounting pipes 51 are symmetrically and fixedly connected to the inside of the fixing plate 62. A clamping block 52 and a fixing ring 53 are slidably connected to the inside of the mounting pipe 51, and the clamping block 52 is engaged with the inside of the clamping groove 55. A spring 54 is installed inside the mounting pipe 51. The spring 54 is sleeved on the side wall of the clamping block 52, and one end of the spring 54 abuts against the side wall of the fixing ring 53. When the elastic filter screen 35 slides on the side wall of the fixing plate 62, after the clamping grooves 55 on the side walls of the two joints are aligned with the clamping block 52, the spring 54 extends to squeeze the fixing ring 53 and the clamping block 52, so that the clamping block 52 moves into the inside of the clamping groove 55 to engage the joint, and the joint and the elastic filter screen 35 are fixed between the two fixing plates 62. When it is necessary to slide the joint, pull the clamping block 52. The clamping block 52 drives the fixing ring 53 to move and compress the spring 54, and the clamping block 52 is separated from the clamping groove 55, so as to facilitate the sliding of the joint between the two fixing plates 62.

[0022] A plurality of limiting rods 69 with arc-shaped side walls are symmetrically installed on the side wall of the fixing plate 62. The elastic limiting rods 69 abut against the side walls of the first joint 34, the elastic filter screen 35 and the second joint 36. The limiting rods 69 prevent the first joint 34 and the elastic filter screen 35 from easily sliding out between the two fixing plates 62, and facilitate driving the fixing plate 62 to move through the joint.

[0023] A protective mechanism 6 for preventing cleaning water from splashing is installed at the bottom end of the extraction mechanism 3; the protective mechanism 6 includes a fixing plate 62, the side wall of the fixing plate 62 is slidably connected to the extraction mechanism 3, and the extraction mechanism 3 is fixed to the side wall of the fixing plate 62 through a limiting mechanism 5; a rubber pad 61 for sealing is installed at the edge of the fixing plate 62, and the rubber pad 61 is slidably connected to the side wall of the deformation joint 23; a flushing pipe 63 is installed obliquely at the bottom end of the fixing plate 62, and a second nozzle 64 with an arc-shaped side wall is installed on the side wall of the flushing pipe 63; a flushing mechanism 4 for cleaning the deformation joint is installed on the side wall of the fixing plate 62, the flushing mechanism 4 includes a support pipe 45, the support pipe 45 is fixedly connected between the two fixing plates 62, connecting plates 43 are symmetrically installed on the side walls of the support pipe 45 and the fixing plate 62, a plurality of first nozzles 44 are installed obliquely on the side walls of the connecting plates 43, and the first nozzles 44 are located inside the fixing plate 62; when cleaning the side wall of the deformation joint 23 and the side wall of the rubber water stop plate 25, high-pressure water enters the inside of the second nozzle 64 through the support pipe 45 and the connecting plate 43, the water is sprayed obliquely through the second nozzle 64 to wash the surface of the concrete, and while the water rushes towards the concrete surface, it provides a thrust in the reverse direction for the operation of the fixing plate 62, reducing the resistance of the fixing plate 62 moving inside the deformation joint 23, and at this time, the rubber pad 61 on one side of the fixing plate 62 is closely attached to the surface of the concrete, the flushing water and impurities of the concrete remain inside the fixing plate 62, the bottom end of the fixing plate 62 is obliquely arranged, facilitating the impurities and water to enter the bottom end of the fixing plate 62 downward, two streams of water are sprayed obliquely through the flushing pipe 63 onto the surface of the rubber water stop plate 25 to wash the surface of the rubber water stop plate 25, the two streams of water collide with each other on the surface of the rubber water stop plate 25 and then move towards the direction of the first joint 34, at this time, a suction force is generated inside the first joint 34, enabling the water to carry impurities and move quickly into the inside of the first joint 34, thereby taking away the impurities on the surface of the rubber water stop plate 25 and preventing the impurities from remaining on the surface of the rubber water stop plate 25; and when the water is sprayed out through the flushing pipe 63, part of the water washes the edge of the rubber water stop plate 25 through the second nozzle 64, so that the edge of the rubber water stop plate 25 is also washed clean by the water.

[0024] The interior of the flushing pipe 63 is threadedly connected to the plug 68, and the plug 68 is slidably connected to the side wall of the second spray head 64; the interior of the plug 68 is snap-fitted and rotatably connected to the hose 66, and one end of the hose 66 is provided with a fixed pipe 67; the fixed pipe 67 is threadedly connected to the second joint 36. The side wall of the fixed pipe 67 is slidably connected to the elastic filter net 35, and the top end of the fixed pipe 67 is located inside the first joint 34; when cleaning the side walls of the deformation joint 23 inside the top plate 22 and the side plate 26, the fixed pipe 67 is rotated into the interior of the second joint 36, one end of the fixed pipe 67 enters the interior of the first joint 34, the fixed pipe 67 closes the elastic filter net 35, then the plug 68 is threadedly connected to the flushing pipe 63, the flushing pipe 63 and the second spray head 64 are closed, and the flushing pipe 63 is communicated with the fixed pipe 67 through the hose 66; when cleaning the side walls of the deformation joint 23 inside the top plate 22 and the side plate 26, the water and impurities inside the fixing plate 62 enter the interior of the fixed pipe 67 and the first joint 34 through the hose 66, and the water inside the fixing plate 62 is pumped away, avoiding water splashing.

[0025] The side wall of the elastic filter net 35 is in an arc structure, and the distance between the two fixing plates 62 gradually decreases along the direction of the elastic filter net 35 towards the support pipe 45, so that a funnel-shaped structure is formed between the two fixing plates 62, facilitating the entry of the elastic filter net 35 between the two fixing plates 62, and one end of the two fixing plates 62 is fixed by the support pipe 45. As the elastic filter net 35 enters between the two fixing plates 62, the other end of the fixing plate 62 is extruded outwards, causing the two fixing plates 62 to expand.

[0026] The center of the elastic filter net 35 and the center of the flushing pipe 63 are in the same plane, in order to facilitate the water sprayed from the interior of the flushing pipe 63 to move towards the elastic filter net 35, so that the water is sucked away through the elastic filter net 35.

[0027] The top end of the fixing plate 62 is in a funnel-shaped structure, and the side wall at the bottom end of the fixing plate 62 is inclined, in order to facilitate the fixing plate 62 to expand and bend the surface to squeeze the rubber pad 61, increasing the sealing performance between the rubber pad 61 and the concrete; a protective pad 65 is installed on the bottom surface of the fixing plate 62. During the cleaning process of the rubber water stop plate 25, two water flows move on the surface of the rubber water stop plate 25 and then move towards the second joint 36. At this time, under the action of the water flow, the elastic protective pad 65 sinks towards the interior of the fixing plate 62, causing part of the splashed water to move along the side wall of the protective pad 65 towards the first joint 34, reducing the amount of water splashing.

[0028] The deformation joint 23 is provided at the connection between the basement 1 and the connecting passage 2. The connecting passage 2 is composed of a bottom plate 21, side plates 26 and a top plate 22. A layer of waterproof coiled material 24 is laid under the bottom plate 21 to enhance the waterproof property of the deformation joint 23. A rubber water stop plate 25 is installed inside the deformation joint 23. And in the deformation joint 23 inside the bottom plate 21, the side wall of the rubber water stop plate 25 is in a "V" shape structure, so as to facilitate the impurities inside the bottom plate 21 to converge at the center inside the rubber water stop plate 25 under the action of gravity, and facilitate the two water flows to collide and move upward inside the "V"-shaped rubber water stop plate 25, so that the water can take away the impurities deposited inside the rubber water stop plate 25.

[0029] A water pump 31 is installed on the surface of the bottom plate 21. The water pump 31 is connected to a grip rod 33 through a first connecting pipe 32. The grip rod 33 is threadedly connected to the first joint 34. In order to facilitate holding the grip rod 33, thereby driving the extraction mechanism 3 and the protection mechanism 6 to move inside the deformation joint 23, and turning on the water pump 31, so that a suction force is generated inside the elastic filter screen 35 and the joint, and the water and impurities are quickly pumped away from inside the deformation joint 23.

[0030] A high-pressure water pump 41 is placed on the surface of the bottom plate 21. The high-pressure water pump 41 is connected to a support pipe 45 through a first connecting pipe 32. One end of the connecting plates 43 on both sides of the support pipe 45 is in a semi-circular structure. The inside of the elastic connecting plates 43 is hollow and in a "V" shape structure, so that the high-pressure water pump 41 can quickly flush water into the inside of the support pipe 45 and the connecting plates 43 through the first connecting pipe 32. The inside of the connecting plates 43 is hollow and in a "V" shape structure, and one end of the connecting plates 43 is semi-circular, thus facilitating the water to converge at one end of the connecting plates 43 and then be quickly sprayed out through the first nozzle 44 to clean the surface of the concrete.

[0031] A construction method for the deformation joint of the basement connecting passage specifically includes the following steps.

[0032] Step 1: Connect the grip rod 33 to the second joint 36, insert the second joint 36 and the elastic filter screen 35 between the two fixing plates 62. As the elastic filter screen 35 enters, the elastic filter screen 35 extrudes the fixing plates 62 outward, causing the two elastic fixing plates 62 to expand outward and increasing the distance between the two fixing plates 62. When the elastic filter screen 35 slides on the side wall of the fixing plate 62, when the clamping grooves 55 on the side walls of the two joints are aligned with the clamping blocks 52, the spring 54 elongates and presses the fixing ring 53 and the clamping block 52, causing the clamping block 52 to move into the inside of the clamping groove 55 to engage the joint, fixing the joint and the elastic filter screen 35 between the two fixing plates 62. Finally, connect the second connecting pipe 42 to the support pipe 45; Step 2: When placing the fixing plate 62 into the deformation joint 23, the fixing plate 62 contracts inward and presses the elastic filter screen 35. At the same time, the elastic filter screen 35 extrudes the fixing plate 62 outward, fixing the fixing plate 62 inside the deformation joint 23. When the fixing plate 62 slides inside the deformation joint 23 and is squeezed, the elastic filter screen 35 extrudes the fixing plate 62 and the rubber pad 61 outward, thereby increasing the sealing between the rubber pad 61 and the concrete, preventing water from leaking out through the gap between the fixing plate 62 and the concrete, and avoiding water splashing; Step 3: Connect the device to an external power supply, turn on the high-pressure water pump 41 and the water pump 31. The operation of the high-pressure water pump 41 causes water to quickly rush into the inside of the support pipe 45, and the operation of the water pump 31 creates suction inside the joint. While cleaning the side walls of the deformation joint 23 and the side wall of the rubber water stop plate 25 at the same time, high-pressure water enters the inside of the second spray head 64 through the support pipe 45 and the connecting plate 43. The water is sprayed obliquely through the second spray head 64 to wash the surface of the concrete. The water continuously washes the surface of the concrete obliquely, cleaning the surface of the concrete. And while the water rushes towards the surface of the concrete, it provides a thrust to the movement of the fixing plate 62 in the opposite direction (as shown in the attachment Figure 7 ), reducing the resistance of the fixing plate 62 moving inside the deformation joint 23. At this time, the rubber pad 61 on one side of the fixing plate 62 is closely attached to the surface of the concrete. The washing water and impurities of the concrete remain inside the fixing plate 62. The bottom end of the fixing plate 62 is inclined, facilitating the downward entry of impurities and water into the bottom end of the fixing plate 62. Two streams of water are sprayed obliquely towards the surface of the rubber water stop plate 25 through the washing pipe 63 to wash the surface of the rubber water stop plate 25. After the two streams of water impact and collide with each other on the surface of the rubber water stop plate 25, they move towards the direction of the first joint 34 (as shown in the attachment Figure 3As shown, the arrow at the bottom of this figure points to the direction of water flow movement. Since the elastic filter net 35 is surrounded by the fixing plate 62 and the support pipe 45 at this time, most of the elastic filter net 35 is blocked, generating suction inside the first joint 34, causing water to carry impurities and move quickly into the inside of the first joint 34, thereby taking away the surface impurities of the rubber water stop plate 25 and preventing impurities from remaining on the surface of the rubber water stop plate 25. During the cleaning process of the rubber water stop plate 25, two water flows move on the surface of the rubber water stop plate 25 and then move towards the second joint 36. At this time, under the action of the water flow, the elastic protective pad 65 sinks towards the inside of the fixing plate 62, causing some splashed water to move along the side wall of the protective pad 65 towards the first joint 34, reducing the amount of water splash, and the water enters between the two fixing plates 62 and contacts the elastic filter net 65, enabling the water to be quickly sucked away. When water is sprayed out through the flushing pipe 63, some water flushes the edge of the rubber water stop plate 25 through the second nozzle 64, so that the edge of the rubber water stop plate 25 is also flushed clean. Step Four: When cleaning the side walls of the deformation joint 23 inside the cleaning top plate 22 and the side plate 26, rotate the fixed pipe 67 into the inside of the second joint 36. One end of the fixed pipe 67 enters the inside of the first joint 34, the fixed pipe 67 closes the elastic filter net 35, then threadedly connect the plug 68 and the flushing pipe 63, close the flushing pipe 63 and the second nozzle 64, and connect the flushing pipe 63 and the fixed pipe 67 through the hose 66 (as shown in the attached Figure 9 、attached Figure 10 figure). When cleaning the side walls of the deformation joint 23 inside the cleaning top plate 22 and the side plate 26, the water and impurities inside the fixing plate 62 enter the inside of the fixed pipe 67 and the first joint 34 through the hose 66, and the water inside the fixing plate 62 is pumped away to avoid water splash. Step Five: When the inside of the deformation joint 23 is cleaned, snap the elastic filter net 35 into the rubber water stop plate 25 inside the bottom plate 21. The cross-section of the side wall of the rubber water stop plate 25 is in a "V" shape, which is convenient for the elastic filter net 35 to be snapped into and fixed in the rubber water stop plate 25. Install a drain pipe 37 at one end of the elastic filter net 35, connect this drain pipe 37 to the external drainage device, and then install waterproof equipment inside the deformation joint 23. During the later use process, if water leaks inside the deformation joint 23, the accumulated water on the surface of the rubber water stop plate 25 can be extracted through the drain pipe 37 and the elastic filter net 35, thereby slowing down the water seepage phenomenon inside the deformation joint 23.

10. The basement connecting passage deformation joint construction device according to claim 9, characterized in that, A construction method for a basement connecting passage deformation joint comprises the following steps: Step 1: inserting the elastic filter net (35) between the two fixing plates (62), the elastic filter net (35) pressing the fixing plates (62) outwards, so that the two elastic fixing plates (62) are stretched outwards; and fixing the joint on the surface of the fixing plates (62) by means of a limiting mechanism (5); Step 2: during the process of placing the fixing plate (62) into the deformation joint (23), the elastic filter net (35) presses the fixing plate (62) and the rubber pad (61) outwards, so that the rubber pad (61) is closely attached to the surface of the concrete, thereby increasing the sealing between the two and preventing water from leaking out from the gap between the rubber pad (61) and the concrete; Step 3: When simultaneously cleaning the side wall of the deformation joint (23) and the side wall of the rubber water stop plate (25), the fixing plate (62) slides inside the deformation joint (23), and high-pressure water is sprayed obliquely through the second nozzle (64) to wash the surface of the concrete, cleaning the concrete surface; due to the blockage of the rubber pad (61), the water and impurities for washing the concrete remain inside the fixing plate (62), and the water inside the fixing plate (62) is sprayed obliquely towards the surface of the rubber water stop plate (25) through the washing pipe (63) to wash the surface of the rubber water stop plate (25). At the same time, the two streams of water impact and collide with each other on the surface of the rubber water stop plate (25) and then move towards the direction of the first joint (34). At this time, suction is generated inside the first joint (34), enabling the water to carry impurities and move quickly into the inside of the first joint (34), thereby taking away the impurities on the surface of the rubber water stop plate (25) and preventing impurities from remaining on the surface of the rubber water stop plate (25).

The water and impurities inside the fixing plate (62) enter the inside of the fixed pipe (67) and the first joint (34) through the hose (66) to prevent water from splashing. Step 5: After the inside of the deformation joint (23) is cleaned, snap the elastic filter screen (35) into the rubber water stop plate (25) inside the bottom plate (21). The elastic filter screen (35) is connected to an external drainage device through a drain pipe (37), and then install waterproof equipment inside the deformation joint (23). During the later use process, if water leaks inside the deformation joint (23), the accumulated water on the surface of the rubber water stop plate (25) can be pumped out through the drain pipe (37) and the elastic filter screen (35), thereby slowing down the water seepage phenomenon inside the deformation joint (23).
