Description

Technical Field

[0001] The invention relates to the technical field of cellar construction, and in particular to a cellar assembly module and a construction method thereof. Background Art

[0002] Wine is a beverage with a long history and rich historical and cultural background. It is also an indispensable part of human society. In traditional Chinese culture, wine is closely related to poetry, etiquette and other aspects.

[0003] According to the survey, the construction of Maotai-flavor liquor factories has the following characteristics: 1. The brewing process is complex, and there are many single projects. The technological characteristics of Maotai-flavor liquor are "three highs and three longs". The complex production process of eight cooling and adding koji and pile fermentation, nine steaming and seven wine extractions leads to many single projects. 2. Strict production season and tight construction period: seasonal production, one production cycle per year, pay attention to "stepping on koji on Dragon Boat Festival, adding sand and feeding on Double Ninth Festival". The delivery node of the koji-making factory is around the Dragon Boat Festival, and the delivery node of the wine-making factory is around the Double Ninth Festival. Once delayed, it will affect the production of liquor for the whole year. 3. There are many cross-operations in the middle and late stages of reverse flow construction, few working surfaces, many types of work, large labor volume, and difficult management. Many unfavorable factors lead to unfavorable conditions such as the construction period and construction quality of the winery.

[0004] Under the traditional method, when constructing a cellar, it is necessary to first conduct multi-level briefings, and to supervise the construction work throughout the entire construction cycle. When excavating the soil of the cellar pit, it is necessary to prevent the excavator from colliding with the foundation or the main structure, damaging the structure, and thus causing structural safety hazards; secondly, within 1m around the central column pile foundation, manual excavation or pneumatic crushing is required, and excavators cannot be used for excavation and crushing to avoid affecting the safety of the central column pile foundation structure. After the cellar stone is built, it is necessary to carry out formwork → pouring concrete rear wall → maintenance and high formwork removal → backfilling behind the wall. After these five processes, the construction of functional areas such as the airing hall can be carried out. There are problems such as large construction period requirements, complex cross-operation of public area construction in the later stage, and few working surfaces. Summary of the invention

[0027] 2. The cellar assembly module and its construction method can realize multiple types of work on the same working surface through the use of prefabricated cellar backfill templates, realizing three-dimensional construction. It not only shortens the construction period and reduces the number of processes, but also reduces the number of peak workers, making the overall construction more reasonable and the cross-operation connection and handover smoother.

[0028] 3. The cellar assembly module and its construction method, as well as the application of cellar assembly modular tools, stagger the peak periods of public area construction and cellar construction. First, it reduces the supply of materials such as steel bars, concrete, and cellar stones in the same period of time, alleviating the pressure of material supply and funds. At the same time, through turnover and three-dimensional construction, the overall labor force changes are smoother, reducing the peak number of workers and also facilitating the reduction of labor costs.

[0029] 4. The cellar prefabricated module and its construction method, because the site selection of Maotai wine-making factories is mostly in mountainous and hilly terrain, through the application of reverse construction flow construction modular tools, the post-excavation construction time is shortened, and the risk of excavation under non-support conditions is greatly reduced.

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1-Figure 8 A cellar assembly module includes a steel casing 1, which is used to protect the pile foundation, solve the problem of collision with the foundation or main structure during machine excavation, and affect the safety of the structure, avoid the need for manual excavation within 1m around the central column pile foundation, and realize three-dimensional operation during decoration and renovation projects; a latch 2 is used to connect and position the various components of the steel casing 1 by mortise and tenon joints, and the mortise and tenon type easy-to-remove steel casing 1 is adopted. The upper and lower sections of the steel casing 1 are formed into a whole by rotating the mortise and tenon joints. Figure 2 As shown, a steady-state structure is formed by the friction between the steel wall and the soil and concrete. Later, the bolt 2 is removed to release the upper steel casing 1 and then the mortise and tenon steady state is destroyed to achieve the purpose of turnover; the cellar comprises a cellar bottom 31 and a plug-in groove 32; a prefabricated cellar backfill template 4 is used to synchronously complete the waterproof and anti-corrosion mortar grouting between the template and the cellar, so as to solve the problem that in the process of "cellar reverse construction", the cellar construction and the second structure and rough decoration are synchronously constructed, resulting in a tight working surface and many cross-operation types; the prefabricated cellar backfill template 4 is used as shown in Figure 6As shown, while ensuring that the cellar wall thickness backfill is inserted in advance, the waterproof and anti-corrosion mortar grouting between the prefabricated cellar backfill template 4 and the cellar bottom 31 is completed simultaneously; the four-corner raised blocks 5, the four-corner raised blocks 5 are fixedly connected to the prefabricated cellar backfill template 4, and are used to ensure the thickness of the grouting material and the quality of the later molding. The four-corner raised blocks 5 set on the pouring plate are mainly to ensure the uniform thickness of the grouting material and the stability of the later molding quality. The specific reasons are as follows: Control thickness: The four-corner raised blocks 5 play a supporting and limiting role, so that the thickness of the grouting material is consistent on the entire board surface, avoiding uneven pouring. This will cause some areas to be too thin or too thick, affecting the strength and stability of the structure. Ensure flatness: The raised blocks can be used as elevation control points during the pouring process, making the surface flatness easier to control, ensuring that the final molding quality meets the design requirements and avoiding offset and subsidence: During the pouring of the grouting material, the raised blocks can play a positioning role to prevent the pouring plate from shifting or sinking during the construction process, thereby ensuring the accuracy of the molding quality and reducing shrinkage deformation: Uniform thickness helps the grouting material reduce uneven shrinkage deformation during the curing process and avoid cracks or deformation on the surface of the finished product.

[0045] A cellar assembly module construction method also includes the following steps:

[0046] Step 1: Measurement and positioning, earth excavation, cushion construction and foundation reinforcement pre-embedded, pre-installation of prefabricated pit backfill template 4, to ensure the stability and precise positioning of the building foundation, to provide support for subsequent projects;

[0047] Step 2: Through the segmented installation of steel casing 1, mortise and tenon structure connection and grouting protection, the mortise and tenon type easy-to-remove steel casing is adopted. Before the middle pile is poured, it is constructed in the same way as the ordinary steel casing. It is first buried in segments to the bottom elevation of the cellar, and constructed simultaneously with the pile foundation. After the earth excavation is completed, the segments are removed to solve the problem of collision with the foundation or the main structure during machine excavation, which affects the structural safety, avoids the need for manual excavation within 1m around the middle column pile foundation, can protect the pile foundation, and realize three-dimensional operation during the decoration and renovation project; mechanical excavation and manual Repair, steel casing 1 ensures the stability of the slope to prevent earth collapse, ensure construction safety and excavation accuracy. When the cellar is reversed, the soil around the central column needs to be excavated, which may cause damage to the structure during the construction process. This method innovatively uses the mortise and tenon type easy-to-remove steel casing 1 to protect the pile structure. After the earth excavation is completed, the mortise and tenon steady state is destroyed by removing the pins to realize the turnover of the steel casing, which protects the safety and stability of the structure while achieving low-carbon green construction;

[0048] Step 3: Place the prefabricated pit backfill template 4 into the plug-in slot 32, so that the trigger block 47 contacts the plug-in slot 32, and the trigger block 47 drives the locking column 45 to release the clamping connection with the template block 41 upward, so that the spring 1 42 drives the pressing positioning plate 43 to extend horizontally to contact the plug-in slot 32, so that the prefabricated pit backfill template 4 is pre-fixed. The pre-fixed template can prevent the template from shifting or shaking before it is completely fixed, providing a stable construction environment for subsequent backfilling operations, simplifying construction steps, reducing manual adjustment and locking time, improving construction efficiency, ensuring operational safety, and preventing the pit structure from being damaged or errors caused by template movement;

[0049] Step 4: Mortar filling and maintenance ensure the forming accuracy and wall quality of the cellar, and enhance the waterproof performance and strength of the cellar wall. When the cellar is reversed, the cellar construction is carried out simultaneously with the second structure and rough decoration. In order to avoid the inconvenience caused by cross-operation, this method innovatively uses the prefabricated cellar backfill template 4. During the drawing review stage, the relevant units are first optimized through the strip foundation, the prefabricated template slot is set, and the prefabricated cellar backfill template 4 is fixed. It can be achieved without affecting the construction of functional areas such as the steamer area. At the same time, the outer wall of the cellar is grouted with waterproof mortar and anti-corrosion mortar. A protective mortar is set on the prefabricated cellar backfill template 4. Layer pier, ensure that the thickness of waterproof mortar and anti-corrosion mortar during grouting meets the requirements of the specifications, strictly explain in the process of prefabricated component production, ensure that the embedded card slot size is correct, pre-embed the lifting lugs in advance, do a good job of prefabricated component maintenance, regularly measure the strength to ensure that the strength meets the requirements during on-site implementation, and do not affect the backfilling in the same period. Before prefabrication, deepen the cellar pit drawings, determine the backfill range between the steamer area and the cellar, and deepen the production according to the range. During prefabrication, according to the deepening drawings, ensure that the protective layer pads are produced according to the required thickness to ensure the thickness of the grouting material during the later grouting construction, and avoid the thickness deviation of the waterproof and anti-corrosion mortar;

[0050] Step 5: After the cellar is formed, the steel casing can be dismantled and recycled section by section to save material costs and ensure the safety of the construction space. Strict instructions are given during the dismantling of the upper and lower sections, and the whole process is supervised. The upper section is dismantled first, and the upper section is destroyed by prying the anchor nails to break the steady state, so that the upper and lower sections can be separated;

[0051] Step 6: After completing the structure and walls, rough decoration is carried out as a base, and fine decoration is carried out to beautify the appearance of the building and improve the internal user experience, thereby enhancing the overall function and aesthetics of the building. Structural acceptance, waterproofing and anti-corrosion acceptance, and overall acceptance are used to comprehensively review the construction quality to ensure that the safety, durability, and functionality of the building meet the design and specification requirements, in preparation for its formal commissioning. Before the implementation of the mortise and tenon type easily removable steel casing, the drawings of the factory buildings that require reverse construction are deepened, the size of the middle piles is optimized, and production is deepened to ensure that the on-site implementation can be turned around.
