Description

Technical Field

[0001] This utility model belongs to the field of cellar technology, specifically relating to prefabricated cellars. Background Technology

[0002] In current engineering construction, cellars, as a common underground facility, are widely used in drainage, ventilation, cable laying, and other fields. Household cellars are common in cold regions and are often used to store vegetables such as potatoes and cabbages. However, traditional cellar structures have revealed many problems in actual use.

[0003] Firstly, from a structural perspective, most existing manholes are constructed using on-site casting. This method not only has a long construction period but also requires a high level of expertise from the construction environment and the workers. If problems arise during construction, such as insufficient compaction of the concrete, it will affect the overall structural strength and stability of the manhole, leading to high maintenance costs later on.

[0004] Secondly, many traditional cellars suffer from poor ventilation. Because the air inside cannot circulate effectively, harmful gases such as carbon dioxide, methane, and hydrogen sulfide easily accumulate. This not only poses a serious threat to the lives of people entering the cellar but also hinders the normal operation of equipment within the cellar.

[0005] Furthermore, traditional cellars lack a reasonable design in terms of internal facilities. For example, entering and exiting a cellar requires a ladder, which is very inconvenient. Moreover, the ladder lacks effective fixation, making it prone to tilting and slipping, thus creating safety hazards. Utility Model Content

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a prefabricated cellar, including a bottom section, a top section, and several intermediate sections. The intermediate sections are located between the bottom section and the top section and are arranged sequentially from bottom to top. The lower end of the bottom section is fixedly connected to a cellar bottom plate. The middle part of the top section has a tapered section with a diameter that gradually decreases from bottom to top. The upper end of the top section has a cellar opening, which is covered with a cellar cover. The cellar cover is composed of a fixed cover plate and a movable cover plate spliced ​​together. The fixed cover plate is fixedly connected to the top section. The movable cover is hinged to a fixed cover or top section on one side. Two air pipes are installed on the fixed cover, one of which is an air inlet pipe and the other is an air outlet pipe. The lower ends of the air inlet pipe and the air outlet pipe extend into the pit and are close to the bottom plate of the pit. The upper ends of the air outlet pipe and the air inlet pipe are located outside the pit. A blower is installed at the upper end of the air outlet pipe. Several foot pedals are connected between the air inlet pipe and the air outlet pipe. The foot pedals are located inside the pit and are arranged sequentially from bottom to top.

[0007] As a preferred embodiment of the above technical solution, the portion of the air inlet pipe located inside the well and the portion of the air outlet pipe located inside the well are each composed of several connecting pipes connected in sequence, with flanges provided at both ends of the connecting pipes, and adjacent connecting pipes being connected by flanges.

[0008] As a preferred embodiment of the above technical solution, the two ends of the foot pedal are respectively connected to the connecting pipe in the air inlet pipe and the connecting pipe in the air outlet pipe via clamps.

[0009] As a preferred embodiment of the above technical solution, a light is installed on one side of the foot pedal.

[0010] As a preferred embodiment of the above technical solution, the connecting pipe at the lowest end of the air inlet pipe and the connecting pipe at the lowest end of the air outlet pipe are respectively connected to the bottom plate of the cellar through a support pipe, and the support pipe has openings on both sides.

[0011] As a preferred embodiment of the above technical solution, the connecting pipe is made of metal, and the bottom section, top section and middle section are made of resin concrete, plastic steel or wood-plastic composite materials.

[0012] As a preferred embodiment of the above technical solution, the upper inner side of the middle section and the upper inner side of the bottom section are respectively provided with a support platform, and the lower inner side of the middle section and the lower inner side of the top section are respectively provided with a support ring, with the support ring placed on the corresponding support platform.

[0013] As a preferred embodiment of the above technical solution, the middle section is bonded to the bottom section, the middle section is bonded to the middle section, and the middle section is bonded to the top section with adhesive.

[0014] The beneficial effects of this utility model are as follows: The prefabricated manhole of this utility model adopts a multi-segment splicing prefabricated structure, which greatly shortens the construction cycle and reduces dependence on the construction environment and the technical level of workers compared with the traditional on-site casting method. The installation of air inlet and outlet pipes promotes air circulation inside the manhole, quickly expelling accumulated harmful gases and ensuring the safety of personnel entering and exiting. The built-in foot pedal, in conjunction with the air inlet and outlet pipes, forms a ladder, providing a safe and convenient access route and reducing the danger of climbing. The depth of the manhole can be arbitrarily changed as needed, making depth control more flexible. Attached Figure Description

[0021] like Figure 1-3 As shown, the prefabricated cellar includes a bottom section 1, a top section 2, and several intermediate sections 3. The intermediate sections 3 are located between the bottom section 1 and the top section 2 and are arranged sequentially from bottom to top. The bottom section 1 is fixedly connected to a cellar bottom plate 4 at its lower end. The top section 2 has a narrowing section 5 with a diameter that gradually decreases from bottom to top in the middle. The top section 2 has a cellar opening 6 at its upper end, and a cellar cover is placed over the opening 6. The cellar cover is constructed by splicing a fixed cover plate 7 and a movable cover plate 8. The fixed cover plate 7 is fixedly connected to the top section 2, and one side of the movable cover is connected to the fixed cover plate. The fixed cover plate 7 is hinged to the top section 2.

In this way, the air inlet pipe 9 and the air outlet pipe 10 can be assembled on-site as needed, without the need to pre-determine the length or perform on-site cutting.

[0023] Furthermore, the two ends of the foot pedal 11 are respectively connected to the connecting pipe 12 in the air intake pipe 9 and the connecting pipe 12 in the air outlet pipe 10 via clamps 14. The clamps 14 can be secured by the corresponding flanges 13 to prevent the foot pedal 11 from loosening and falling off.

[0024] Furthermore, a light 15 is installed on one side of the foot pedal 11. The light 15 can illuminate the interior of the well and also serve as a guide for those going up and down the ladder. The light 15 is preferably a long strip of LED light.

[0025] Furthermore, the lowermost connecting pipe 12 of the air inlet pipe 9 and the lowermost connecting pipe 12 of the air outlet pipe 10 are respectively connected to the bottom plate 4 of the kiln via a support pipe 16. Openings 17 are provided on both sides of the support pipe 16. The support pipe 16 provides support for the air inlet pipe 9 and the air outlet pipe 10, fixing them in place and preventing them from shaking. Airflow from the bottom enters and exits the air inlet pipe 9 and the air outlet pipe 10 through the openings 17.

[0026] Furthermore, the connecting pipe 12 is made of metal, while the bottom section 1, top section 2, and middle section 3 are made of plastic steel. The metal connecting pipe 12 ensures structural strength and service life, has a certain load-bearing capacity, and can be used as a ladder.

[0027] Furthermore, the upper inner side of the middle section 3 and the upper inner side of the bottom section 1 are respectively provided with support platforms 18, and the lower inner side of the middle section 3 and the lower inner side of the top section 2 are respectively provided with support rings 19, with the support rings 19 placed on the corresponding support platforms 18.
