Description

Technical Field

[0001] This utility model relates to the technical field of cast-in-place retaining devices, specifically a concrete cast-in-place retaining structure. Background Technology

[0002] Concrete-cast retaining structures typically refer to continuous walls and similar foundation pit retaining walls formed by on-site concrete pouring. They are constructed by excavating a narrow, deep trench around the foundation pit using specialized machinery (such as hydraulic grabs and trenching machines), placing a steel cage inside the trench, and then pouring concrete to form continuous reinforced concrete walls that serve as retaining and water-stopping structures during the foundation pit excavation phase.

[0003] Among them, cast-in-place concrete retaining structures have the advantages of high rigidity, prevention of deformation, waterproofing, and greater depth. Concrete is poured inside the retaining wall, and after the concrete cools, it forms a pile, which serves as the most basic building support. Cast-in-place concrete retaining structures have good application prospects in areas with deep foundation pits, complex environments, and high waterproofing requirements.

[0004] Although the cast-in-place retaining structure has many beneficial effects, the following problems still exist: During the process of waiting for the concrete to solidify after casting, in order to prevent early plastic shrinkage cracks and ensure later strength development, it is necessary to spray water on the concrete to control the temperature evenly. However, manual water spraying is inefficient and unsafe. At the same time, when different foundation piles are needed for different depths, it is inconvenient to freely assemble the retaining structure and not convenient to freely select a suitable retaining structure according to the current required depth. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] 1. Technical problems to be solved:

[0007] To address the aforementioned issues regarding the concrete retaining structure, which requires watering during the curing process to prevent early plastic shrinkage cracks and ensure later strength development, manual watering is inefficient and unsafe. Furthermore, it is inconvenient to freely assemble the retaining structure when different piles are needed for different depths, making it difficult to freely select the appropriate retaining structure based on the required depth.

[0008] Therefore, the purpose of this utility model is to provide a concrete pouring retaining structure that uses a water pump to draw water from the inside of an annular water tank to pour the poured concrete. At the same time, a water supply pipe can also be connected to the connecting flange, eliminating the need for manual watering and improving safety and watering efficiency. Furthermore, the connecting base plate can be spliced ​​to the connecting top plate using double-headed bolts. Different first and second retaining sleeves can be fixedly connected at the bottom of the connecting top plate and the top of the connecting base plate, thereby allowing for free determination of the foundation pile depth.

[0034] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0035] This utility model provides an overall structural schematic diagram of a concrete casting retaining structure implementation method, including:

[0036] Please see Figures 1-6This embodiment of a concrete pouring enclosure structure includes a first enclosure 1 and a second enclosure 2. A composite frame 23 is bolted to the top of the first enclosure 1 and the second enclosure 2. A composite plate 24 is welded inside the composite frame 23. A feed box 25 is welded to the top of the composite frame 23. By feeding concrete into the feed box 25, the concrete flows continuously downwards along the inner plate 7, gradually filling the interior of the first enclosure 1 and the second enclosure 2. An annular water tank 26 is welded to the outer wall of the composite frame 23. A fixing frame 27 is welded to the top of the annular water tank 26. A water pump 28 is bolted to the top of the fixing frame 27. The water pump 28 draws water from the annular water tank 26 and delivers it to the water delivery pipe 29, eliminating the need for manual watering. The water delivery pipe 29 is bolted to the top of the water pump 28, and one end of the water delivery pipe 29 is welded with… After water is fed into the water supply pipe 29, the water can be sprayed out through the nozzle 30 and spread on the poured concrete, thereby preventing early plastic shrinkage cracks and ensuring later strength development. The bottom of the annular water tank 26 is welded with a support rod 31, which can support the annular water tank 26 and ensure that the annular water tank 26 is not easily detached from the surface of the composite frame 23. One end of the support rod 31 is welded with the first enclosure 1 and the second enclosure 2. The top of the annular water tank 26 is bolted to the connecting flange 32, which can be connected to the water supply pipe. Water from the water source is transported to the annular water tank 26 through an external additional water pump to ensure that there is always water inside the annular water tank 26. The water pump 28 is electrically connected to the external distribution box through the connecting wire. The distribution box has an external control panel through the connecting wire. The control panel refers to a control device with buttons.

[0037] It is worth noting that, in order to freely combine the retaining structure to the required depth according to the depth of the foundation pit, specifically, the bottom of the first retaining sleeve 1 and the second retaining sleeve 2 are fixedly connected to a connecting base plate 17 by bolts. The connecting base plate 17 has a combination hole 18 inside, and the inner circumference of the combination hole 18 is threaded with a double-ended bolt 19. Through the mutual cooperation of the double-ended bolt 19 and the combination hole 18, the connecting base plate 17 and the connecting top plate 16 can be spliced ​​together, thereby increasing the depth of the first retaining sleeve 1 and the second retaining sleeve 2. The outer circumference of the double-ended bolt 19 is threaded through... A connecting top plate 16 is connected via a thread. The bottom of the connecting top plate 16 is fixedly connected to the first enclosure 1 and the second enclosure 2 by bolts. The connecting top plate 16 and the connecting bottom plate 17 have positioning holes 21 inside. The connecting top plate 16 and the connecting bottom plate 17 can be quickly aligned through the positioning holes 21, and the double-ended bolts 19 can be installed inside the connecting top plate 16 and the connecting bottom plate 17 quickly and easily. The connecting top plate 16 and the connecting bottom plate 17 have through holes 20 inside, which allows the poured concrete to flow normally and does not easily affect the normal pouring of concrete.

[0038] Next, in order to allow the concrete to flow quickly and to prevent concrete from adhering to the inner walls of the first enclosure 1 and the second enclosure 2, specifically, a combination block 6 is welded to the side of the first enclosure 1, a combination groove 5 is embedded in the surface of the combination block 6, the combination groove 5 is opened on the side of the second enclosure 2, a first sliding groove 3 is opened inside the first enclosure 1 and the second enclosure 2, a first sliding plate 4 is slidably connected inside the first sliding groove 3, and an inner plate 7 is fixedly connected to the front of the first sliding plate 4.

[0039] Meanwhile, in order to facilitate the lifting of the first protective sleeve 1 and the second protective sleeve 2 by the crane mechanism, specifically, the first protective sleeve 1 and the second protective sleeve 2 are welded with side handles 9. The outer circumference of the side handles 9 is fitted with anti-slip rings 10. The anti-slip rings 10 are made of aluminum alloy rings with rod-shaped undulations on the surface. The rod-shaped undulations on the outer circumference of the aluminum alloy anti-slip ring increase the locking effect between the rod-shaped undulations and the crane mechanism, thereby facilitating the lifting of the first protective sleeve 1 and the second protective sleeve 2 by the crane mechanism.

[0040] Furthermore, in order to quickly position and fix the bottommost first enclosure 1 and second enclosure 2, specifically, a positioning base plate 33 is welded to the bottom of the first enclosure 1 and the second enclosure 2, and ground nails 22 are welded to the four corners of the bottom of the positioning base plate 33.

[0041] It is worth noting that, in order to facilitate the adjustment of the position of the movable block 14 so that it can cooperate with the connecting base plate 17, the connecting top plate 16 and the positioning base plate 33, specifically, the sides of the first enclosure 1 and the second enclosure 2 are provided with a second sliding groove 12, the interior of the second sliding groove 12 is slidably connected with a second sliding plate 13, and the side of the second sliding plate 13 is welded with a movable block 14.

[0042] Finally, to facilitate the movement of the movable block 14, specifically, the interior of the movable block 14 is connected to a positioning screw 11 by a thread, the outer circumference of the positioning screw 11 is connected to a first side fixing plate 8 by a thread, and the bottom end of the positioning screw 11 is connected to a second side fixing plate 15 by a rotating shaft.

[0043] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0044] Combination Figures 1-6 The concrete casting retaining structure of this embodiment is used in the following specific process:

[0045] 1: When using this type of concrete pouring retaining structure, the height to be used must first be determined, that is, the depth required for the foundation piles must be determined. After the determination is completed, the combination groove 5 and the combination block 6 on the side of the first retaining sleeve 1 and the second retaining sleeve 2 are spliced ​​together, and it is positioned in the bottom pit by ground nails 22 as the most basic retaining structure.

[0046] 2: After the base of the retaining structure is installed, the top plate 16 is connected to the top of the first retaining sleeve 1 and the second retaining sleeve 2 of the foundation by bolts, and the bottom plate 17 is connected by double-headed bolts 19. At the same time, the top of the bottom plate 17 is connected to the other first retaining sleeve 1 and the second retaining sleeve 2 by bolts. Thus, the retaining structure of appropriate height can be spliced ​​according to the depth of the foundation pit. At the same time, the through holes 20 opened inside the bottom plate 17 and the top plate 16 will not affect the normal pouring of concrete.

[0047] 3: After the retaining structure is completed and the concrete is poured, the water supply pipe can be connected through the connecting flange 32. Then, the external water pump of the retaining structure is started. The external water pump can draw water from the water source and deliver it to the inside of the annular water tank 26 through the water pipe. After the annular water tank 26 is filled with water, the water pump 28 can be started through the control panel. The water pump 28 pumps the water inside the annular water tank 26 into the water delivery pipe 29 and sprays it out with the nozzle 30 to control the temperature of the poured concrete, thereby strengthening early plastic shrinkage cracks and ensuring later strength development. With the water supply from the external water pump and the automatic water pumping of the water pump 28, there is no need for manual watering by the staff.

[0048] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
