Abstract
Description
Technical Field
[0001] This utility model relates to the field of brewing cellars, specifically a wall structure for baijiu fermentation cellars that improves the amount and stability of cellar mud adhesion. Background Technology
[0002] Traditional baijiu fermentation pits mostly employ earthen pits or brick-built straight-wall structures, which have significant drawbacks: weak bonding between the pit mud and the walls, leading to easy detachment and cracking over long-term use; insufficient mud application restricts the enrichment of functional microorganisms; and poor pit stability affects the consistency of base liquor quality. While existing brick-built pit walls increase structural strength, the solid walls lack effective anchoring points, and the pit mud can only be applied superficially, resulting in poor adhesion. Some improvement schemes attempt to add perforated structures, but these do not solve the problems of layered load-bearing and optimization of microbial carriers, and still carry the risk of wall deformation due to clogging and stress concentration. Utility Model Content
[0003] This utility model addresses the problems mentioned in the background art by providing a wall structure for baijiu fermentation cellars that improves the amount and stability of cellar mud adhesion.
[0004] This utility model provides a wall structure for a liquor fermentation cellar that improves the amount and stability of cellar mud adhesion, comprising, from bottom to top, a first solid wall, a second solid wall, a perforated wall, a reinforced concrete top layer, a stone bonding layer, and bluestone slabs;
[0005] The first solid wall is a nine-layer solid brick masonry structure, and the second solid wall is a five-layer solid brick masonry structure. The thickness of the solid bricks used in the first and second solid walls is different.
[0006] The decorative wall structure, from bottom to top, consists of a lower decorative wall, a lower solid wall, a middle decorative wall, a middle solid wall, an upper decorative wall, an upper solid wall, a top decorative wall, and a top solid wall. The lower, middle, and upper decorative walls are all nine layers of solid brick masonry with several cross-shaped decorative openings. The top decorative wall is six layers of solid brick masonry with several cross-shaped decorative openings. The lower, middle, upper, and top solid walls are all one layer of solid brick masonry.
[0007] Furthermore, the first solid wall uses MU15.0 shale solid bricks with a thickness of 370mm.
[0008] Furthermore, the second solid wall uses MU15.0 shale solid bricks with a thickness of 240mm.
[0009] Furthermore, the solid bricks used in the perforated wall are MU15.0 shale solid bricks with a thickness of 240mm.
[0010] Furthermore, the thickness of the reinforced concrete top layer is 50mm, with internal continuous reinforcement of 3Ф10 and distribution reinforcement of 10@150.
[0011] Furthermore, the thickness of the stone adhesive layer is 40mm.
[0012] Furthermore, the thickness of the bluestone slab is 30mm.
[0013] Furthermore, the cross-shaped eyelet is filled with pit mud, and bamboo strips are inserted vertically.
[0014] Furthermore, the cross-shaped perforations on the perforated wall are arranged in an array, with the spacing between individual perforated bricks being 120mm+240mm+120mm.
[0015] Furthermore, the first solid wall, the second solid wall, and the perforated wall are all constructed using M15 cement mortar.
[0016] Compared with the prior art, the beneficial technical effects of this utility model are as follows:
[0017] 1. Increased mud adhesion: The multi-layered cross-shaped holes in the wall are filled with mud and embedded with bamboo strips to form a three-dimensional grid anchoring system. This not only solves the problem of mud easily falling off traditional holes, but also increases the amount of mud adhering to the side wall of the pit. In addition, the bamboo strips form a biological carrier skeleton, which accelerates the colonization of functional bacteria.
[0018] 2. Enhanced structural stability: The multi-layered alternating solid brick bands built into the perforated wall disperse the expansion stress of the kiln mud and prevent stress accumulation. The double solid wall base layer composed of the first and second solid walls resists the high pressure of fermentation at the bottom of the kiln, thus improving compressive strength. The reinforced concrete top layer suppresses top displacement, achieving layered compressive strength.
[0019] 3. Enhanced durability: MU15.0 solid shale bricks are used to resist acid corrosion, and the bluestone slabs and stone bonding layer isolate external erosion, forming a multi-level protection that extends the life of the pit.
[0020] 4. Improved quality of the liquor: The stability of the mud improves the aging of the cellar mud, resulting in higher quality liquor. Attached Figure Description

[0027] Example 1
[0028] Please see Figure 1This embodiment provides a baijiu fermentation pit wall structure 1 that improves the mud adhesion and stability. It includes, from bottom to top, a first solid wall 101, a second solid wall 102, a perforated wall 103, a reinforced concrete top layer 104, a stone bonding layer 105, and a bluestone slab 106. The first solid wall 101 is a nine-layer solid brick masonry, and the second solid wall 102 is a five-layer solid brick masonry. The thickness of the solid bricks used in the first solid wall 101 and the second solid wall 102 is not... The same applies to the decorative wall 103, which consists of a lower decorative wall, a lower solid wall, a middle decorative wall, a middle solid wall, an upper decorative wall, an upper solid wall, a top decorative wall, and a top solid wall from bottom to top. The lower decorative wall, the middle decorative wall, and the upper decorative wall are all nine layers of solid brick masonry and have several cross-shaped decorative holes 107. The top decorative wall is six layers of solid brick masonry and has several cross-shaped decorative holes 107. The lower solid wall, the middle solid wall, the upper solid wall, and the top solid wall are all one layer of solid brick masonry.
[0029] In this embodiment, the flower-shaped wall has multiple layers of alternating solid brick strips inside to disperse the expansion stress of the pit mud and prevent stress accumulation. The double solid wall base layer composed of the first solid wall and the second solid wall resists the high pressure of fermentation at the bottom of the pit, thus improving the compressive strength. The reinforced concrete top layer suppresses the displacement of the top layer, thus achieving layered compressive strength.
[0030] Specifically, the first solid wall 101 uses MU15.0 shale solid bricks with a thickness of 370mm; the second solid wall 102 uses MU15.0 shale solid bricks with a thickness of 240mm; the perforated wall 103 uses MU15.0 shale solid bricks with a thickness of 240mm; the reinforced concrete top layer 104 has a thickness of 50mm, with internal continuous reinforcement of 3Ф10 and distribution reinforcement of 10@150; the stone bonding layer 105 has a thickness of 40mm; and the bluestone slab 106 has a thickness of 30mm.
[0031] Specifically, the cross-shaped holes 107 are filled with pit mud, and bamboo strips 108 are inserted vertically. After filling with pit mud and embedding bamboo strips 108, a three-dimensional grid anchoring system is formed, which not only solves the problem of mud easily falling off traditional holes, but also increases the amount of pit mud attached to the side wall of the pit. In addition, the bamboo strips 108 form a biological carrier skeleton, which accelerates the colonization of functional bacteria.
[0032] Specifically, the cross-shaped perforations 107 on the perforated wall 103 are arranged in an array, with the spacing between individual perforated bricks being 120mm+240mm+120mm.
[0033] Specifically, the first solid wall 101, the second solid wall 102, and the perforated wall 103 are all constructed using M15 cement mortar.
[0034] Application examples
[0035] like Figure 2As shown, a baijiu (Chinese liquor) fermentation pit includes rectangular side walls formed by four walls. The inner side of the rectangular walls is coated with a layer of pit mud 2. All four walls adopt the baijiu fermentation pit wall structure 1 of Example 1. The baijiu fermentation pit has an east-west length of 2.2m, with cross-shaped perforations 107 arranged in a 7+6+7 pattern from bottom to top. It also has a north-south length of 3m, with cross-shaped perforations 107 arranged in a 9+8+9 pattern from bottom to top. The mortar joint thickness is 12mm, the cement mortar strength is M15, the mortar joint fullness reaches 100%, and any mortar leaking out during grouting is removed and cleaned.
[0036] The above description is a preferred embodiment of the present utility model, used to explain the technical solution of the present utility model, and is not intended to limit the present utility model. Those skilled in the art can make conventional modifications, equivalent substitutions and improvements within the spirit and principles of the present utility model, all of which are still included within the protection scope of the present utility model.
