Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a foundation treatment device. Background Art

[0002] As the foundation of the building structure, the construction quality of the foundation is directly related to the overall stability, safety and service life of the building. In construction projects, foundation treatment is a crucial link, which involves a variety of technical means to ensure that the bearing capacity, deformation control and waterproof performance of the foundation meet the design requirements. Traditional foundation treatment methods include but are not limited to replacement method, compaction method, preloading method, grouting reinforcement and foundation cushion construction. The selection and application of these methods need to be comprehensively considered based on the foundation soil conditions, building load characteristics and environmental factors.

[0003] In the foundation treatment process, especially after the completion of the roller leveling and the stabilization of the base layer, the laying of the waterproof layer becomes an important link that cannot be ignored. Especially in the underground engineering part, effective waterproofing measures are essential to prevent groundwater leakage and protect the building structure from water erosion. At present, the laying of waterproof membranes mostly relies on manual operation, hot melt welding with a blowtorch, and the use of membrane retracting and unwinding equipment to assist in laying. This process is not only labor-intensive and has high technical requirements for workers, but also inefficient. The laying quality is easily affected by human factors, time-consuming and costly.

[0004] In addition, with the continuous advancement of construction technology and the expansion of project scale, the complexity and comprehensiveness of foundation treatment are increasing. A single foundation treatment method is often difficult to meet the construction needs under complex geological conditions. Therefore, the market urgently needs a foundation treatment equipment that can integrate multiple foundation treatment technologies and has high efficiency and automation characteristics to improve construction efficiency, reduce labor intensity, ensure construction quality, and adapt to construction needs under different geological conditions.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Example 1: Please refer to Figure 1-Figure 14 The present invention provides a technical solution: a foundation treatment device, including a roller 1, and also including a connecting frame 2 fixedly arranged at the front end of the roller 1, a reel unit 1 3 and a reel unit 2 4 are arranged on the connecting frame 2, the reel unit 1 3 is movably arranged on the connecting frame 2, and the reel unit 2 4 is movably arranged at the front end of the reel unit 1 3, and the two can slide relative to each other to unfold and lay a waterproof roll. During laying, the distance between the two can be adjusted according to the construction requirements, specifically, it needs to be adjusted according to the overlap length of two adjacent waterproof rolls after laying:

[0042] A connecting oil cylinder 5 is provided at the front end of the roller 1, and the two ends of the connecting oil cylinder 5 are respectively connected to the roller 1 and the drum unit 2 4, so that the drum unit 1 3 and the drum unit 2 4 can be folded and unfolded on the roller 1, thereby not affecting the normal foundation compaction operation;

[0043] There are two air supply tubes 6, which are respectively arranged in the drum unit 1 3 and the drum unit 2 4. The air supply tube 6 can discharge air toward the bottom. The road roller 1 is provided with a double-outlet fan, which is connected to the air supply tube 6 to convey airflow thereto. The air inlet ends of the two air supply tubes 6 are provided with heating wires. A controller for controlling the temperature of the heating wires is provided on the outer side of the air supply tube 6, so as to achieve precise control of the temperature. A heating plate 7 is slidably provided at one end of the air supply tube 6 located in the drum unit 1 3, and the heating plate 7 can be used to perform heat-melt connection on the overlapping parts of adjacent waterproof rolls when laying the waterproof rolls. Since the waterproof rolls need to overlap each other during laying to achieve seamless laying, it is necessary to reserve the overlapping length. By heating the overlapping part, the asphalt layer at the overlapping part is melted, so that the two adjacent waterproof rolls can be connected in the subsequent compaction process.

[0044] A transverse plate 8 is fixedly provided on the upper end of the drum unit 2 4, and the two ends of the connecting cylinder 5 are rotatably connected to the roller 1 and the transverse plate 8 respectively. When the connecting cylinder 5 is extended, it can drive the drum unit 1 3 and the drum unit 2 4 to unfold and make them close to the ground.

[0045] A slide groove 9 is provided on the connecting frame 2, and a slider 10 is slidably arranged in the slide groove 9. An extension rod 11 is slidably arranged in one end of the connecting frame 2, and an extension block 12 is fixedly arranged at the end of the extension rod 11. The two sides of the reel unit 3 are rotatably connected with the slider 10 and the extension block 12 through a rotating shaft. Through the design of the extension block 12, when the reel unit 13 and the reel unit 24 are separated from each other and unfolded, the reel unit 13 drives the slider 10 and the extension block 12 to move, the slider 10 moves in the slide groove 9, and the extension block 12 drives the extension rod 11 to move, so that the two can achieve stable support when unfolding.

[0046] The reel unit 3 includes a frame 31, and the two sides of the frame 31 are rotatably connected to the slider 10 and the extension block 12 respectively, so that it can move laterally along the connecting frame 2. The front and rear sections inside the frame 31 are rotatably provided with a roller 32 and a pressure roller 33 respectively. The end of the roller 32 is connected to a reduction motor, which can drive the roller 32 to rotate through the reduction motor, thereby realizing the laying of the waterproof membrane. The pressure roller 33 is movably installed in the frame 31, and the pressure roller 33 is used for compaction after the waterproof membrane is laid.

[0047] Both ends of the pressure roller 33 are provided with connecting shafts 34, a rotating block 35 is rotatably provided on one side of the frame 1 31, and the connecting shaft 34 is rotatably connected with the rotating block 35. A mounting groove 36 is provided on the other side of the frame 1 31, and the connecting shaft 34 on the other side is placed in the mounting groove 36. A limit plate 37 is slidably provided above the mounting groove 36, and the limit plate 37 is slidably provided in the frame 1 31. A notch for the limit plate 37 to be inserted is provided on one side of the mounting groove 36. A connecting spring 38 is provided at one end of the limit plate 37 located in the frame 1 31, and the end of the connecting spring 38 is connected to the inside of the frame 1 31;

[0048] One end of the pressing roller 33 can move on the frame 1 31 so as to install the waterproof coiled material thereon. This is because before laying the waterproof coiled material, since the waterproof coiled material is always in a rolled shape during storage and transportation, stress will accumulate inside. During normal laying, the waterproof coiled material needs to be unfolded for pre-laying, and then rolled up for subsequent laying operations after the stress disappears. However, this method is time-consuming. Therefore, in this embodiment, the stress is relieved by heating first and then cooling.

[0049] Specifically, when relieving stress, first pull the limit plate 37 to shrink it into the frame 31. At this time, one end of the pressure roller 33 can be lifted from the frame 31, and then the rolled waterproof material can be installed on the pressure roller 33. Then, one end of the waterproof roll is wrapped around the two air supply cylinders 6 and wound around the roller 32. The waterproof roll on the outside of the pressure roller 33 is unwound by the rotation of the roller 32, and then rolled up by the roller 32. During this process, the initial state between the frame 1 31 and the frame 2 41 is maintained, that is, the two do not move relative to each other. During the unwinding process of the roll, one of the air supply cylinders 6 heats it, and the other air supply cylinder 6 subsequently cools it, and finally it is rolled up on the roller 32 to release the stress of the roll. Similarly, another group of rolls are carried out on the roll unit 2 4 in the same way.

[0050] The reel unit 24 includes a frame 241 slidably arranged at the front end of the frame 1 31, a roller 242 is rotatably arranged in the frame 241, and a reduction motor is connected to one end of the roller 242. The reduction motor drives the roller 242 to rotate so as to reel in the coil when relieving stress and unreel it when laying.

[0051] An expansion cylinder 13 is provided between frame 1 31 and frame 2 41, and the two ends of the expansion cylinder 13 are fixedly connected to frame 1 31 and frame 2 41 respectively. When the expansion cylinder 13 is extended, frame 1 31 and frame 2 41 are separated from each other. Since frame 2 41 is connected to the roller 1 through the connecting cylinder 5, frame 1 31 will move relative to the roller 1 to realize the laying of the roll material at the front end and one side of the roller.

[0052] An air outlet is provided at the bottom of the air supply tube 6, and a heating plate 7 is slidably provided at the air inlet end of the air supply tube 6 located on the frame 1 31. A movable groove 14 is provided at the bottom of the air supply tube 6. In order to ensure the sealing performance, a telescopic partition should be provided in the movable groove 14. A connecting pipe 15 is slidably provided in the movable groove 14. A movable ring 16 is provided at the top of the connecting pipe 15. The movable ring 16 is a thin-walled shape with an opening on one side. The top of the connecting pipe 15 is connected to the movable ring 16, and the bottom of the connecting pipe 15 is connected to the heating plate 7. The heating A plurality of air outlets are provided on the surface of the plate 7, a movable ring 16 is slidably arranged in the air supply tube 6, a fixed rod 17 is fixedly arranged in the air supply tube 6, a fixed plate 18 is arranged at the end of the fixed rod 17, and the outer diameter of the fixed plate 18 is the same as the inner diameter of the movable ring 16. When the movable ring 16 moves to be flush with the fixed plate 18, the air inlet end of the air supply tube 6 is blocked, and at this time, the air flow enters the heating plate 7 through the connecting pipe 15, and a piston tube 19 for driving the connecting pipe 15 to move is also arranged on the frame 131;

[0053] When the piston tube 19 drives the connecting tube 15 to move, the connecting tube 15 drives the movable ring 16 to move and connect with the fixed disk 18. At this time, the movable ring 16 and the fixed disk 18 block the air inlet of the air supply tube 6, so that the air flows through the movable ring 16 and the connecting tube 15 into the heating plate 7. At this time, the heating wire is energized to make the incoming air high-temperature air. When laying, the roller 2 42 is laid in the front, and the roller 1 32 is laid on the side of the roller 2 42. The heating plate 7 is located at the overlap of the two, and then the overlap is heated when moving. Then the pressure roller 33 can compact the overlap to ensure that the two are tightly connected.

[0054] The piston tube 19 includes a cylinder 191 fixedly arranged at the bottom of the frame 31, a slide bar 192 is slidably arranged in the cylinder 191, and the end of the slide bar 192 is fixedly connected to the connecting tube 15. A support spring 193 is arranged in the cylinder 191, and the two ends of the support spring 193 are respectively fixedly connected to the slide bar 192 and the inner side of the cylinder 191. An electromagnet 194 is arranged in the cylinder 191, and a magnetic block 195 is arranged at one end of the slide bar 192 located in the cylinder 191. When the electromagnet 194 is energized, it can repel the magnetic block 195, and the magnetic block 195 drives the slide bar 192 to move, and the slide bar 192 drives the connecting tube 15 to move;

[0055] In summary, the present device can not only perform foundation compaction operations, but also perform waterproofing roll laying operations, including stress relief and laying of waterproofing rolls. Specifically, when removing stress, the roll is first installed on the pressure roller 33, and then one end of the roll is wound around the two air supply tubes 6 and wound around the roller 1 32 or the roller 2 42. Since the roller 1 32 or the roller 2 42 winds up the roll, the roll is first heated and then cooled to achieve stress relief. The specific temperature is adjusted by the material of the roll and the actual construction requirements, which will not be repeated here. After the roll is destressed in the above manner, the outer sides of the roller 1 32 and the roller 2 42 are each wound with a roll of waterproof material, and then laying can be performed;

[0056] During laying, first connect the oil cylinder 5 to start and drive the frame 1 31 and the frame 2 41 to move toward the ground and then close to the ground. At this time, the bottom of the pressure roller 33 contacts the ground, and then the oil cylinder 13 is unfolded and extended to drive the frame 1 31 and the frame 2 41 to separate from each other. At this time, the roller 1 can move forward for laying, and the roller 1 32 and the roller 2 42 unwind the waterproof coiled material under the drive of the reduction motor. During laying, the air supply tube 6 on the frame 2 41 blows air downward to make the laid waterproof material fit the foundation. The air supply tube 6 on the frame 1 is blocked by the movable ring 16. At this time, the heating plate 7 discharges air to heat the overlap of the two to achieve a hot melt connection at the overlap. During laying, the waterproof material unrolled by the roller 1 32 is compacted by the pressure roller 33, and the waterproof material unrolled by the roller 2 42 is compacted by the roller 1.

[0057] Example 2: Please refer to Fig.15 , Embodiment 2 has the same main structure as Embodiment 2, except that the side walls of the frame 1 31 and the frame 2 41 are both fixedly provided with a stabilizing frame 20, the stabilizing frame 20 is fixedly provided with a guide rod 21, the guide rod 21 located on the frame 1 31 is slidably provided in the frame 2 41, and the guide rod 21 located on the frame 2 41 is slidably provided in the frame 1 31;

[0058] Through the design of the guide rods 21 on both sides, the frame body 1 31 and the frame body 2 41 can be more stable when they move relative to each other and unfold, so that the two can form a frame shape when unfolded, which is more stable when in use.

[0059] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0060] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
