Description

Technical Field

[0001] This utility model relates to the field of pile foundation construction technology, and in particular to a pile mouth protection device for pile foundation construction. Background Technology

[0002] Most existing pile opening protection devices for pile foundation construction are protective casings (also known as hole opening safety nets), which are standardized products customized according to pile hole construction. The size of the protective casing can be designed and customized according to the size of the casing. The protective casing is composed of two semicircles, with a 4 mm thick steel mesh on top to enhance the protective effect. A drilling operation window is left in the middle. The frame of the protective casing is welded from square steel and the whole is made of galvanized material. It is then sprayed with red or yellow paint. For specific structure, please refer to https: / / www.sohu.com / a / 590787491_120561885.

[0003] There are also square-shaped protective devices, such as horizontal protective devices (published at http: / / www.360doc.com / content / 22 / 0430 / 21 / 38979078_1029180323.shtml). When setting up horizontal protection, the surrounding area should be isolated and safety warning signs should be posted. Horizontal protection for pile holes can be achieved by using horizontal steel cover plates, with guardrails used for isolation around the perimeter. The guardrails must be installed securely.

[0004] Based on the above search and combined with existing technology, it was found that existing pile opening protection devices for pile foundation construction are all integrated protection devices (generally requiring customization according to the size of the pile opening). However, the completed protection device can only be used for the current pile opening or a pile opening of the same size as the current pile opening, and cannot be applied to other pile openings. The reuse rate is low, and the size of the manufactured protection device is fixed, which makes it inconvenient to store and transport, and its use is not flexible and convenient enough. Therefore, a pile opening protection device for pile foundation construction is needed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example: Reference Figures 1-5 The pile head protection device for pile foundation construction shown includes a mesh panel unit 1, a support grid plate 2, and a working window cover plate 3;

[0030] Multiple mesh panel units 1 are provided, and the multiple mesh panel units 1 are evenly distributed along the same horizontal plane. The multiple mesh panel units 1 are detachably fixed to each other by bolts. The mesh panel unit 1 includes a fixed frame 11 and a steel mesh 12. The fixed frame 11 is a square frame. A groove 111 is provided on the top of the fixed frame 11. The steel mesh 12 is welded from multiple crisscrossing steel bars. The steel mesh 12 is fixedly embedded in the groove 111. First waist holes 112 for bolts to pass through are provided on all sides of the fixed frame 11.

[0031] Multiple support grid plates 2 are also provided, and multiple support grid plates 2 are arranged around multiple mesh plate units 1. The multiple support grid plates 2 are respectively detachably fixed to the corresponding mesh plate units 1 by bolts. The support grid plate 2 is a vertical plate with grid holes. The top of the support grid plate 2 is provided with a second waist hole 21 for bolts to pass through. The second waist hole 21 is the same as the first waist hole 112. The bolts pass through the first waist hole 112 and the second waist hole 21 and are used with nuts to fix the mesh plate unit 1 and the support grid plate 2.

[0032] Multiple mesh panel units 1 and supporting grid plates 2 together form a cover and are installed outside the pile opening. Multiple mesh panel units 1 have a working window in the middle. The mesh panel units 1 around the working window are detachably fixed with a working window cover plate 3 that closes the window by bolts. The four corners of the working window cover plate 3 are provided with a first through hole 31 for bolts to pass through. The first through hole 31 corresponds to the position of the first connecting hole 113. After the bolt passes through the first through hole 31, the lower end is screwed into the first connecting hole 113.

[0033] Based on the above structure, the existing integrated protective device is improved into a modular and assembleable structure. By splicing multiple mesh plate units 1 and multiple supporting grid plates 2, a square-shaped cover is formed. This cover can be placed on the pile opening to provide good protection. At the same time, the number of spliced ​​modules (mesh plate units 1 and supporting grid plates 2) can be adjusted according to needs, so as to flexibly adapt to pile openings of different sizes. Compared with the integrated welded protective device, the modular unit in this embodiment can also be easily assembled and disassembled (by bolt connection and disassembly), which facilitates transportation and secondary use, greatly improving the flexibility of use, and at the same time, the scope of application is wider and the use is more convenient.

[0034] Furthermore, the pile mouth protection device for pile foundation construction also includes a connecting plate 4, on which multiple second through holes 41 for bolts to pass through are provided;

[0035] The top four corners of the fixed frame 11 are provided with first connecting holes 113, and the top of the support grid plate 2 is provided with second connecting holes 22. Both the first connecting holes 113 and the second connecting holes 22 are threaded holes. The bolt passes through the second through hole 41 and is screwed into the first connecting hole 113 or the support grid plate 2.

[0036] By opening corresponding first connecting holes 113 and second connecting holes 22 on the fixed frame 11 and the supporting grid plate 2, the connecting angles of multiple adjacent fixed frames 11 and the connecting angles of the fixed frame 11 and the supporting grid plate 2 can be strengthened and fixed by the connecting plate 4 and bolts, thereby improving the overall stability of the pile mouth protection device for pile foundation construction and enabling it to play a good and reliable protective role.

[0037] Furthermore, the work window cover plate 3 is provided with third waist holes 32 around its perimeter for bolts to pass through. The third waist holes 32 allow multiple work window cover plates 3 to be connected and fixed by bolts, thereby forming a larger area cover plate, which can meet the different work window needs during construction and is more flexible and convenient to use.

[0038] The fixed frame 11 and the working window cover plate 3 both form vertical sidewalls extending downwards at their lower ends. The first waist hole 112 and the third waist hole 32 are respectively opened on the vertical sidewalls of the fixed frame 11 and the working window cover plate 3.

[0039] The working principle of this utility model is as follows: During daily use and transportation, the mesh panel unit 1, supporting grid plate 2, working window cover plate 3, connecting plate 4, and bolts are transported separately. During on-site assembly, multiple adjacent mesh panel units 1 can be fixed by passing bolts through the first waist hole 112 of the mesh panel unit 1. Then, by passing bolts through the first waist hole 112 and the second waist hole 21, the mesh panel unit 1 and supporting grid plate 2 can be fixed together, forming a square cover with a working window in the middle. Furthermore, by passing bolts through the first through hole 31 of the working window cover plate 3 and screwing them into the first connecting hole 113, the working window can be closed, achieving comprehensive protection. Workers can also place the connecting plate 4 at the connecting corners of multiple mesh panel units 1, and at the connection points between the mesh panel unit 1 and the supporting grid plate 2. At the upper end of the connection of the support grid plate 2, a bolt is passed through the second through hole 41 and screwed into the first connection hole 113 or the second connection hole 22 to achieve a reinforced connection at the corners of multiple mesh plate units 1 and at the connection between the mesh plate unit 1 and the support grid plate 2, thereby improving the overall strength of the cover. The square cover can be placed on the pile opening to achieve a good protective effect. During the operation, it is only necessary to remove the bolts on the working window cover plate 3 and remove the working window cover plate 3 to expose the working window for the corresponding construction work. After use, the workers can disassemble the mesh plate unit 1, support grid plate 2, working window cover plate 3 and connecting plate 4 by disassembling in reverse and removing multiple bolts in sequence for storage and transportation, which can achieve a higher reuse rate and reduce the cost of use.

[0040] It should be further noted that the bolts used in this application require the use of nuts, while the other part does not. This is a choice that those skilled in the art can make, and no further limitation is made here. However, it should be understood that those skilled in the art can use them flexibly according to installation requirements, and this should not be regarded as a limitation on this application.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
