Description

Technical Field

[0001] The utility model relates to the technical field of pile structures in building engineering construction, and particularly relates to a ground pile structure for building engineering construction. Background Technique

[0002] The ground pile structure used in building engineering construction is an important basic engineering measure to ensure the stability and bearing capacity of buildings, especially important in areas with complex geological conditions or insufficient soil bearing capacity. There are many types of ground piles, which can be divided into the following main types according to different construction processes, force-bearing characteristics and application scenarios:

[0003] 1. Precast driven piles: including prestressed concrete piles, steel pipe piles, etc. These piles are prefabricated in the factory in advance and then transported to the construction site and driven into the ground by a pile driver.

[0004] 2. Bored cast-in-place piles: Holes are excavated at the predetermined positions, then steel reinforcement cages are placed in the holes, and then concrete is poured to form pile bodies, which are suitable for various geological conditions, especially soft soil foundations.

[0005] 3. Helical ground piles: These ground piles are drilled into the ground by rotation. Because of their convenient installation and small environmental impact, they are often used in the installation of solar panels, temporary structures or occasions that require rapid construction.

[0006] 4. End-bearing piles and friction piles: End-bearing piles rely on the soil resistance at the bottom of the piles to bear the load and are suitable for hard rock formations; friction piles mainly rely on the friction between the pile bodies and the soil to transfer the load and are suitable for softer soil layers.

[0007] 5. Driven piles: The piles are directly driven into the ground by mechanical force and are suitable for strata such as sand and gravel.

[0008] 6. ESD ground piles: mainly used for shock absorption and earthquake prevention, and are commonly found in buildings such as factories, warehouses, and laboratories that require additional earthquake protection.

[0009] 7. Bridge pier ground piles: Such ground piles usually require deeper driving depths and higher bearing capacities to support the huge weight and dynamic loads of bridges.

[0010] During the construction process, selecting the appropriate type of ground pile requires considering various factors such as soil conditions, building loads, construction costs, and environmental protection requirements. In addition, ground pile construction also requires specialized mechanical equipment, such as pile drivers, grouting equipment, measuring instruments, etc., to ensure the accurate installation of the pile body and construction quality. With technological progress, automated and intelligent construction technologies and equipment have also been gradually applied to ground pile construction to improve efficiency and safety. Existing ground pile structures are all limited to making a vertical hole, lacking branch insertions into the soil. The ground pile cannot grip the soil like tree roots, resulting in low connection strength and unstable structure of the ground pile. For example, the Chinese utility model patent with the patent application number 202321511588.8 discloses a ground pile for building construction that is easy to install, but this ground pile has low connection strength and poor stability.

[0011] Therefore, there is an urgent need to design a ground pile structure for building engineering construction to solve the problems of low connection strength and poor stability of existing ground pile structures. Utility Model Content

The fixing blocks slide radially inside and outside the pile barrel along the sliding grooves.

A plurality of chutes are provided on the pile cylinder 7, and a fixed block 9 is slidably connected in the chute. The fixed block 9 slides radially inside and outside the pile cylinder 7 in the chute.

[0030] The bottoms of both the outer pile and the inner pile 6 are conical heads. Four fixing nails 8 are fixedly connected to the fixing plate 5. The fixing nails 8 are inserted into the ground to facilitate connection with the ground. The fixing plate 5 is provided with an installation hole for inserting the pile cylinder 7 and an outer hole adapted to the position of the fixing block 9. The outer hole communicates with the installation hole.

[0031] The outer side surface of the fixing block 9 extends outside the pile cylinder 7, the inner side surface of the fixing block 9 is located inside the pile cylinder 7, the top and bottom surfaces of the fixing block 9 are slidably connected in the sliding grooves on the inner wall of the pile cylinder 7. The inner and outer side surfaces of the fixing block 9 are both inclined surfaces, which are inclined from top to bottom and from outside to inside. The inclination of the outer inclined surface is to facilitate breaking the soil during pile driving, and the inclination of the inner inclined surface is to facilitate guiding and sliding in cooperation with the conical head of the inner pile 6.

[0032] The upper inner side of the sliding groove is provided with a second limiting groove 10, the lower inner side of the sliding groove is provided with a third limiting groove 11, and the lower outer side of the sliding groove is provided with a fourth limiting groove 12. The top surface of the fixing block 9 is fixedly connected with a first limiting block 1 located outside the pile cylinder 7 and a second limiting block 2 located inside the pile cylinder. The second limiting block 2 is fitted and limited to enter the second limiting groove 10.

[0035] When the fixing block 9 of the present utility model is in use, when driving the outer pile, at this time, the bottom end of the outer side surface of the fixing block 9 is flush with the outer circumferential surface of the pile cylinder 7, so that the part of the fixing block 9 located outside the pile cylinder 7 is an inverted triangle, thereby relying on the inclined surface to break the soil, and at this time, the first limiting block 1 abuts against the outer circumferential surface of the pile cylinder 7, and the third limiting block 3 is inserted into the third limiting groove 11.

[0036] When the inner pile 6 is inserted into the pile cylinder 7, under the extrusion of the inner pile 6, the fixing block 9 is driven to slide outward and the fixing block 9 is inserted into the surrounding soil, thereby increasing the contact area and improving the stability. At this time, the second limiting block 2 is inserted into the second limiting groove 10, and the fourth limiting block 4 is inserted into the fourth limiting groove 12, thereby enhancing the connection strength between the fixing block 9 and the pile cylinder 7.

[0037] Then, concrete is poured into the gap between the pile cylinder 7 and the inner pile 6. At this time, part of the concrete will seep out from the sliding groove, thereby strengthening the soil around the outer pile and further enhancing the stability.
