Description

Technical Field

[0001] The utility model belongs to the technical field of municipal engineering equipment, and particularly relates to a telescopic steel ring template device for reserved pipeline holes in a cast-in-place inspection well. Background Art

[0002] When the method of first pouring the inspection well and then connecting the pipe to the inspection well is adopted, holes for pre-installing the pipes are reserved in the inspection well during the construction process. The holes are generally filled with tires, wooden boards, bricks, etc.

[0003] However, when using tires, wooden boards, brickwork and other filling methods for construction, it is easy to have poor sealing, resulting in leakage and displacement of fillers during the pouring of concrete. In addition, after the formwork is removed, there will be problems such as slag falling and hollowing in the holes, and excess concrete needs to be chiseled out a second time. This method increases construction time and cost, and affects construction quality.

[0004] The above problems are all manifested in the inconvenience of disassembly and assembly, and are prone to poor filling effects, which affects the production efficiency and quality of the entire equipment processing process. Utility Model Content

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model provides a telescopic steel ring template device for reserved pipe holes in cast-in-place inspection wells. The steel ring template device is convenient to install and disassemble during the construction of reserved pipe holes in inspection wells, reduces the time for manual chiseling, etc., and can effectively speed up the overall municipal engineering construction progress.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1As shown, a telescopic steel ring formwork device for reserved pipe holes in a cast-in-place inspection well includes a movable steel ring 1, a fixed connecting piece 3 is arranged on the front side of the movable steel ring 1, basket screws 2 are penetrated on both sides of the fixed connecting piece 3, and an extension steel ring 4 is welded to the bottom of the movable steel ring 1.

[0024] When in use, carry out construction layout, foundation pit excavation, foundation treatment, cushion pouring, steel bar binding, bottom plate pouring and other work according to the design drawings. Then, during the process of tying the vertical and horizontal steel bars of the inspection well, reserve holes of the size of the telescopic steel ring formwork device, and reserve a protective layer thickness of 35mm. In addition, reserve 3 to 5 steel bars for fixing the telescopic steel ring formwork device. After the bottom plate of the inspection well is poured, fix the telescopic steel ring formwork device with the release agent on the outside to the reserved steel bars of the inspection well. It can be fixed by binding or spot welding. The position and orientation of the telescopic steel ring formwork device are determined according to the direction of the pipeline. Then install the internal and external templates of the inspection well and adjust the position of the telescopic steel ring formwork device to make it in close contact with the template to ensure that the elevation and position meet the pipeline drainage requirements. After acceptance, pour the concrete and vibrate it to make it dense. After the concrete strength reaches the requirement, remove the inspection well formwork and the telescopic steel ring formwork device. The telescopic steel ring formwork device is removed by turning the basket screw 2 to shrink the movable steel ring 1, thereby separating it from the concrete. Finally, install the pipeline and fill the gap between the pipe end and the hole with 1:2 cement mortar. Micro-expansion agent should be added to the mortar.

[0025] As a preferred embodiment of the present invention, Figure 4 As shown, this embodiment provides a retractable steel ring formwork device for reserved pipe holes in a cast-in-place inspection well. The movable steel ring 1 includes a second toughness layer 8, and the second toughness layer 8 is specifically made of high-alloy ultra-high strength and toughness steel material.

[0026] This embodiment is to provide limited support for the inner side of the base steel ring 9, thereby improving the high toughness of the inner side. By means of synchronous internal and external reinforcement, the main body of the device is supported with toughness, thereby avoiding affecting its service life due to multiple bending.

[0027] In some embodiments, Figure 4 As shown, a base steel ring 9 is welded to the outer side of the second toughness layer 8, and the base steel ring 9 is specifically made of carbon fiber reinforced steel material.

[0028] This embodiment provides a base material with a long service life for the device, so that the service life of the device is not affected by adjusting the bending degree of the steel ring many times during use.

[0029] In some embodiments, Figure 4 As shown, a first toughness layer 7 is welded to the outer side of the base steel ring 9 , and a weather-resistant layer 6 is welded to the outer side of the first toughness layer 7 .

[0030] This embodiment mainly considers setting up multiple protective structures for improving toughness and service life during use, so as to avoid the steel ring composed of a single material from reaching the end of its self-bending life during multiple daily adjustments, which will cause a certain impact on the entire processing process.

[0031] In some embodiments, Figure 4 As shown, the first toughness layer 7 is specifically made of aluminum alloy reinforced steel material, the weather-resistant layer 6 is specifically made of weather-resistant steel material, and the wear-resistant coating 5 is sprayed with polyurethane paint.

[0032] This embodiment mainly considers ensuring the high toughness and bending resistance of the main body of the device during use, while providing a certain weather resistance effect to reduce the corrosion of chemical substances in the external environment.

[0033] In some embodiments, Figure 4 As shown, the outer side of the weather-resistant layer 6 is sprayed with a wear-resistant coating 5, and the wear-resistant coating 5 is sprayed with polyurethane paint.

[0034] This embodiment mainly considers that during the use of the device, a wear-resistant coating of a constant thickness is evenly sprayed on its surface to improve the wear resistance of its main body, thereby avoiding the wear of the device surface caused by high-hardness substances in the external environment, thereby extending the service life of the equipment main body.

[0035] In some embodiments, Figure 4 As shown, an extension steel ring 4 is welded to the bottom of the movable steel ring 1, and the extension steel ring 4 is slidably connected to the contact position of the surface of the movable steel ring 1.

[0036] This embodiment mainly considers that during the use of the device, it can ensure that the steel ring has a certain extension range to avoid the situation where the steel ring cannot be adjusted to the appropriate specifications in time when there are some special specifications and dimensions required.

[0037] This embodiment mainly considers ensuring the high toughness and bending resistance of the main body of the device during use, while providing certain weather resistance and wear resistance, so as to reduce the erosion of chemical substances in the external environment and the wear of the surface of the device caused by high-hardness substances, thereby extending the service life of the main body of the equipment.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
