Detailed Implementation

[0018] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0019] See Figure 1As shown, this utility model discloses a prefabricated waterproof tower crane foundation structure, including a tower crane base 1, which is cast at the bottom of the foundation pit. Multiple stacked cement well rings 2 are provided on the tower crane base 1. Supporting steel sleeves 3 are installed inside the cement well rings 2. A tower crane mounting seat 4 is provided on top of the supporting steel sleeves 3 and the cement well rings 2. A tower crane 18 is mounted on the tower crane mounting seat 4. A partition wall 9 is constructed on the tower crane base 1. Between the partition wall 9 and the cement well rings 2, from bottom to top, there are sequentially arranged a stabilizing layer 17, a gravel filling layer 16, a cement layer 14, a waterproof layer 15, a sand and gravel layer 13, and a curing layer 12. A drainage system is provided on the outside of the partition wall 9. The drainage ditch 7 and partition wall 9 have drainage outlets 8. The solidification layer 12 is made of cement mortar, facilitating pedestrian movement. The gravel layer 13 is a mixture of small stones and sand. The crushed stone filling layer 16 is filled with large stones, serving to solidify the bottom and prevent collapse. The stabilizing layer 17 is made of reinforced concrete, possessing high strength and resistance to deformation. When it rains, the accumulated water seeps through the gravel layer 13 and solidification layer 12 into the waterproof layer 15. Under the action of the hemispherical structure of the waterproof layer 15, it flows to the drainage outlet 8 at the bottom and from there into the drainage ditch 7 for drainage. This effectively prevents water from seeping into the underlying base layer and causing it to collapse. It also effectively protects the stability of the supporting steel sleeve 3 and cement well ring 2, thereby protecting the tower crane mounting base 4 installed above them. This ensures the tower crane mounting base 4 is installed very firmly, improving safety and reducing the occurrence of malfunctions. By pouring the tower crane support platform 1 at the bottom of the foundation pit, the tower crane support platform 1 effectively prevents groundwater from seeping in and damaging the upper structure. It also serves a leveling function, allowing for better installation of the supporting steel sleeve 3 and cement well ring 2. The supporting steel sleeve 3 and cement well ring 2 have a certain degree of waterproofing. At the same time, the structure is stable and firm, and the tower crane foundation 1 is installed on it without loosening or collapsing. At the same time, the construction of the cement well ring 2 is simple and quick, only requiring stacking, which effectively shortens the construction period. By setting up a stabilizing layer 17, a crushed stone filling layer 16, a cement layer 14, a waterproof layer 15, a sand and gravel layer 13, and a curing layer 12, the structure around the tower crane foundation is stable and firm, and has good waterproof and drainage functions. It can quickly drain accumulated water and prevent long-term water accumulation. It effectively prevents collapse or cracking caused by water accumulation, improves safety, and effectively ensures the construction progress.

[0020] Specifically, multiple tie rods 5 are provided between the tower crane mounting base 4 and the curing layer 12. The tie rods 5 are arranged at an angle, with one end connected to the tower crane mounting base 4 and the other end connected to the curing layer 12 through expansion bolts. This strengthens the installation structure of the tower crane mounting base 4. Under the pull of the tie rods 5, the force is more evenly distributed, effectively ensuring the installation firmness of the tower crane mounting base 4.

[0021] Preferably, the top of the cement layer 14 and the waterproof layer 15 are hemispherical structures with a high center and low periphery. The drainage outlet 8 is opened on one side above the waterproof layer 15. Under the action of the hemispherical structure of the waterproof layer 15, the water flows to the bottom drainage outlet 8 and flows into the drainage ditch 7 for drainage, effectively preventing water from seeping into the underlying base layer and causing the underlying base layer to collapse, so that this structure has a good drainage function.

[0022] Furthermore, adjacent cement well rings 2 are solidified and connected by cement mortar, which effectively fills the gaps between the cement well rings 2 and improves their firmness.

[0023] Furthermore, an isolation sleeve 11 is provided inside the supporting steel sleeve 3, and a cement column 10 is provided inside the isolation sleeve 11 to strengthen the mechanical strength of the intermediate structure and make the installation of the tower crane mounting base 4 more stable.

[0024] Furthermore, the waterproof layer 15 is made of chloroprene rubber asphalt and has a thickness of 2-5cm. The waterproof layer 15 has excellent waterproofing ability and effectively prevents water from the upper layer from seeping into the lower base layer.

[0025] Furthermore, the bottom of the tower crane mounting base 4 is welded to the supporting steel sleeve 3, and the tower crane mounting base 4 is connected to the cement well ring 2 by expansion bolts, so that the tower crane mounting base 4 can be firmly installed on the supporting steel sleeve 3 and the cement well ring 2.

[0026] Furthermore, a support cover 6 is provided on the top of the drainage ditch 7 to provide protection and prevent people above from stepping into the hole.

[0027] In this embodiment, a prefabricated tower crane foundation waterproof structure is used such that the bottom of the tower crane mounting base 4 is welded to the supporting steel sleeve 3, and the tower crane mounting base 4 is connected to the cement well ring 2 by expansion bolts, so that the tower crane mounting base 4 can be firmly installed on the supporting steel sleeve 3 and the cement well ring 2. The accumulated water above seeps through the sand and gravel layer 13 and the curing layer 12 into the waterproof layer 15. Under the action of the hemispherical structure of the waterproof layer 15, it flows to the drain outlet 8 at the bottom and flows into the drainage ditch 7 for drainage, effectively preventing the accumulated water from seeping into the base layer below and causing the base layer below to collapse. It effectively protects the stability of the supporting steel sleeve 3 and the cement well ring 2, and thus protects the tower crane mounting base 4 installed on it, making the tower crane mounting base 4 very firmly installed, improving safety, and reducing the occurrence of failures. By pouring the tower crane foundation 1 at the bottom of the foundation pit, the tower crane foundation 1... This system effectively prevents groundwater from seeping in and damaging the structure above, while also leveling the surface to facilitate the installation of the supporting steel sleeve 3 and cement well ring 2. The supporting steel sleeve 3 and cement well ring 2 provide a degree of waterproofing while ensuring structural stability and firmness. The tower crane foundation 1, installed on top, will not loosen or collapse. Furthermore, the use of cement well ring 2 simplifies and speeds up construction, requiring only stacking and layering, effectively shortening the construction period. By incorporating a stabilizing layer 17, a gravel filling layer 16, a cement layer 14, a waterproof layer 15, a sand and gravel layer 13, and a curing layer 12, the structure around the tower crane foundation becomes stable and firm, providing excellent waterproofing and drainage capabilities. This prevents long-term water accumulation, effectively preventing collapse or cracking caused by water accumulation, thus improving safety and ensuring construction progress. This prefabricated tower crane foundation waterproofing device of this invention has excellent waterproofing and drainage capabilities, effectively preventing collapse or cracking, improving safety, and ensuring construction progress.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model. These modifications and improvements will not affect the effectiveness of the present utility model or the practicality of the patent.
