Description

Technical Field

[0001] The utility model belongs to the technical field of building foundations, in particular to an anti-freezing and pulling device for a water solar pile column structure. Background Art

[0002] In recent years, new energy has ushered in a vigorous development, and solar power stations such as solar energy and solar thermal have been built on a large scale. Usually, the photovoltaic brackets, heliostat brackets and collector brackets of solar power generation projects adopt a pile-column integrated structure. The column foundation is the main load-bearing body, bearing various forms of forces such as vertical loads, horizontal loads, and torsional loads. This requires the column foundation to have the ability to resist compression, shear and torsion. However, for solar power stations built in frozen areas, there is also a special frost heave effect, which will produce frozen pull-up force. If the pull-up displacement is too large, it will damage the column foundation, thereby affecting the safe and stable operation of the upper equipment and solar power stations.

[0003] Generally, for the anti-frost heave of column structures on land foundation soil layers, measures such as replacing non-frost heave foundation soil, changing the foundation form, and taking thermal insulation measures can be taken to eliminate or reduce the frost damage caused by frost heave, and these measures have been included in the "Code for Design of Building Foundations GB 50007-2011". However, the water solar pile column structure is located in the water, and its frost heave damage is different from the frost heave of the foundation soil. It is mainly affected by the frost heave of the water body. The measures taken should consider not only the impact of frost heave on the column, but also some characteristics of the water body itself, such as corrosion and floating of anti-frost heave facilities. At present, conventional anti-freeze heave measures are not applicable, and there is a lack of relatively mature and effective measures. Utility Model Content

[0011] Furthermore, the cross sections of the casing and the pile structure are both circular or polygonal.

Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0024] The utility model is further described in detail below with reference to the accompanying drawings:

[0025] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 They are respectively a cross-sectional view and a top view of an anti-pullout device for an aquatic solar pile column structure of the utility model, comprising a pile column structure 1, a sleeve 2 and a telescopic tube 3. The outer periphery of the solar pile column structure 1 is provided with a sleeve 2, the middle of the sleeve 2 is provided with a telescopic tube 3, and the upper and lower ends of the sleeve 2 are connected to the solar pile column structure 1.

[0026] See also Figure 1 , the two ends of the casing 2 extend to the upper and lower water level respectively. The casing 2 and the telescopic tube 3 are directly sleeved on the local position of the pile structure 1 affected by the frost heave of the water body, and the frost pull force is transferred to the casing. In this case, the structure of the utility model can transfer the frost pull force of the solar pile column and act on the casing, thereby avoiding the frost pull effect on the solar pile column.

[0027] The principle is: the frost heave force acting on the solar pile column structure is transferred to the casing, and under the limiting effect of the telescopic tube, the casing can move up and down within the deformation range of the telescopic tube, effectively reducing the uplift effect of the uplift force generated by the frost heave on the solar pile column structure, and can solve the problem of the above-water solar pile column structure being affected by the frost heave of water. At the same time, the utility model is simple to operate and has low economic cost, and can effectively solve engineering problems, thereby ensuring the safe and stable operation of the upper equipment of the solar pile column structure and the solar power station.

[0028] Specifically, the sleeve 2 is used to be sleeved on a local position of the pile column structure 1. The sleeve 2 is adapted to the pile column structure 1 and has a circular or polygonal cross section. The telescopic tube 3 is located in the middle of the sleeve 2, and both ends of the telescopic tube 3 are connected to the sleeve 2. One end of the sleeve 2 is connected and fixed to the telescopic tube 3, and the other end is connected and fixed to the pile column structure 1.

[0029] The sleeve 2 and the telescopic tube 3 are adapted to the pile structure 1, and for example, the cross-sections of the sleeve 2 and the telescopic tube 3 can be circular or polygonal; the polygons can be triangles, rhombuses, squares, etc. The specific shapes are not limited in this application and can be designed accordingly according to actual needs.

[0030] The telescopic tube 3 is a part of the casing 2, and both ends of the telescopic tube 3 are connected to the casing 2. The sum of the lengths of the casing 2 and the telescopic tube 3 is less than the length of the pile structure 1, and the casing 2 is sleeved on the periphery of the pile structure 1. The telescopic tube 3 is adapted to the structure of the casing 2 and is consistent with the cross section of the pile structure 1. One end of the telescopic tube 3 is fixed to the bottom surface of the upper casing 2; the other end of the telescopic tube 3 is fixed to the top surface of the lower casing 2.

[0031] When the utility model is used, the specific operations are:

[0032] The casing 2 and the telescopic pipe 3 are sleeved at the local position of the pile column structure 1. The specific requirement is that the two ends of the casing 2 are respectively extended to the upper and lower water level lines to transfer the frost heave force to the casing;

[0033] The telescopic tube 3 and the sleeve 2 are assembled and fixed into one by means of mechanical slots, spiral joints, etc. The upper and lower ends of the sleeve are fixed to the pile structure 1 by flexible connection, which must meet the upper and lower displacement deformation strength of the sleeve.

[0034] The casing 2 is made of elastic material with strength and quality grade matching the engineering requirements and corresponding elastic coefficient, and needs to meet the strength and durability requirements. According to the engineering cost and requirements, the material can be hard PVC pipe, high-strength cold-resistant and corrosion-resistant steel pipe, alloy pipe, etc.

[0035] The telescopic tube 3 adopts the strength and quality grade matching the engineering requirements, needs to meet the sealing and cold resistance requirements, and has the elasticity and durability matching the displacement deformation and engineering requirements. According to the engineering cost and requirements, the material can be rubber hose, metal hose, etc.

[0036] Before installing the anti-freezing pull device for the water solar pile structure, select the appropriate casing 2, hose 3 and related fastener materials according to the requirements of relevant specifications, frost pull type, and solar pile size, and follow the relevant requirements. Figure 1-2 Processing anti-freeze pull device.

[0037] As a specific solution, the utility model uses mechanical slots or other fasteners to assemble and fix the telescopic tube 3 and the sleeve 2. The upper and lower ends of the sleeve 2 are fixed to the pile structure 1 by flexible connection to realize the installation of the anti-freezing pull device of the water solar pile structure.

[0038] During the specific construction, according to the on-site environment, the casing 2 is made of materials with certain strength and quality grade to withstand the frost heave force of the water body and meet the requirements of cold resistance and durability.

[0039] During the specific construction, according to the on-site environment, the telescopic tube 3 is made of elastic material with a certain strength and quality grade, coordinates the displacement and deformation of the casing 2, and plays a sealing role to prevent water from entering the space between the casing 2 and the pile column structure 1. Therefore, the material used for the casing 2 must meet the requirements of sealing and cold resistance, and at the same time have a certain degree of elasticity and durability to meet the displacement and deformation requirements.

[0040] During the specific construction, according to the on-site environment, the flexible connection between the casing 2 and the pile column structure 1 not only bears the sealing function to prevent water from entering the space between the casing 2 and the pile column structure 1, but also has the function of adjusting the deformation of the casing 2. Therefore, the material used for the flexible connection must meet the requirements of sealing and cold resistance, and at the same time have certain elasticity and durability to meet the requirements of displacement deformation.

[0041] The above steps completely construct the anti-pullout device for the water solar pile column structure. The utility model of the anti-freezing and pulling-out device for the water solar pile column structure transfers the frost heaving force acting on the solar pile column structure to the sleeve. Under the limiting action of the telescopic tube and the flexible connection, the sleeve can move up and down within a certain deformation range, effectively reducing the upward pulling effect of the upward pulling force generated by the frost heaving on the solar pile column; in addition, the device is simple and easy to operate, with low economic cost, effectively solving engineering problems, and thus ensuring the safety and stability of the solar pile column structure and upper equipment.
