[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments.

[0050] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0051] Reference Figure 1 As shown, this embodiment provides a method for constructing a prefabricated concrete pit bottom trench, comprising the following steps:

[0052] S101, customizing the assembled concrete template 1 according to the size of the pit bottom branch ditch 3 made of aluminum plate, and fixing it with the template clamp 4, reserving two holes 5 at the position of the assembled concrete short side 6 of the assembled concrete 2, and then introducing the assembled concrete 2 into the template.

[0053] S102, demoulding and installing the assembled concrete 2, connecting the spring 8 and the steel bar 7 and placing them in the reserved hole 5, and reserving the hole in advance when pouring the cellar well ring beam;

[0054] S103. After the position is accurately positioned, the compressed spring 8 is relaxed, the steel bar 7 enters the reserved hole 5, the assembled pit bottom ditch is connected to the hole 5 reserved in the pit ring beam, and a prepared aluminum plate is glued to the aluminum plates in the assembled pit bottom ditch at both ends with acrylic AB glue to form a whole, and the installation of the assembled concrete pit bottom ditch is completed.

[0055] Specifically, in this embodiment, the specific construction process is: determine the size of the pit bottom ditch according to the architectural drawing, large-scale drawing and aluminum plate of the winemaking plant, and determine the three-dimensional model; determine the position of the ring beam and the reserved hole 5 of the pit bottom ditch; clean the site of the formwork site to ensure that there is no dust and debris on the site; build the template according to the three-dimensional model of the pit bottom ditch and the size of the aluminum plate, use appropriate tools and materials to fix and support the template to ensure the stability and surface flatness of the template, and the obtained template is as follows Figure 2 As shown; make and tie the steel mesh according to the requirements of the design drawings, place and tie the steel protection layer pads; the arrangement of steel bars 7 must meet the requirements to ensure the strength and stability of the concrete; use stainless steel and bolts to fix and support the assembled pit bottom ditch concrete formwork; apply an appropriate amount of release agent on the assembled pit bottom ditch concrete formwork; inject concrete into the assembled pit bottom ditch concrete formwork, and the mix ratio and pouring process of the concrete shall depend on the situation; during pouring, the uniformity and density of the concrete shall be ensured to avoid voids and leakage; stir the concrete in the assembled pit bottom ditch concrete formwork and wait for it to solidify. After solidification, the assembled pit bottom ditch concrete shall be cured, and the residue and dirt on the stainless steel formwork shall be cleaned in time; after the curing is completed, use appropriate tools to remove the formwork to avoid secondary damage to the formwork, and then transport the assembled pit bottom ditch concrete to the winery room; before putting into the cellar, connect the steel bar 7 and the spring 8 and put them into the hole 5 reserved in the assembled concrete pit bottom ditch, and seal the hole 5 with the reaction plate; through the hole 5 reserved by the pit ring beam, the center line position, etc.; accurately position the assembled pit bottom ditch concrete in the pit; remove the reaction plate at one end, the steel bar 7 pops out, and connects with the hole 5 reserved by the ring beam, and repeats the above operation at the other end; put the long aluminum plate in the hole 5 reserved between the pits, and use acrylic AB glue to assemble the aluminum plate of the pit bottom ditch concrete; the connection part does not need to be grooved, which is conducive to the discharge of gas and avoidance of back grooves; one end of the clamp made of steel bar 7 is fixed to the assembled pit bottom ditch concrete, and the other end is inserted into the soil to prevent movement; the prefabricated cover plate is embedded in the groove of the assembled concrete pit ditch, and after paving, the pit bottom mud is paved to complete the construction. The pit bottom ditch obtained by the construction is as follows Figure 3 shown.

[0056] In order to meet the construction period requirements, this embodiment provides a method for constructing a prefabricated concrete cellar bottom ditch, which ensures the construction quality and improves the construction efficiency. In the prefabricated project, it can effectively reduce the pollution to the environment and achieve green environmental protection. It can also be applied to various similar scenes according to the requirements of different projects and is generally applicable to the cellars of wine factories.

[0057] Furthermore, in this embodiment, in order to make the pit bottom construction more targeted and intuitive, this embodiment constructs a three-dimensional construction model by means of three-dimensional modeling, and performs construction according to the three-dimensional model. The specific three-dimensional model construction process includes:

[0058] The three-dimensional laser holographic data of the cellar building is collected by a three-dimensional laser scanner, and the holographic data is pre-processed to obtain processed holographic data; the processed holographic data is compressed using the human eye visual space frequency analysis method to obtain compressed data; the compressed data is imported into the 3D Max software to obtain a three-dimensional model of the cellar building.

[0059] In the preprocessing process, this embodiment adopts the nearest iteration (ICP) algorithm, and after translating and rotating each scattered data by the minimum error value, the scattered data is effectively coincided, and the holographic data scattered in different coordinate systems are converted into the same coordinate system to complete the data registration and obtain the registered data. Specifically:

[0060] In this embodiment, the collected initial cellar three-dimensional laser holographic data is expressed by the following formula:

[0061] Q={Q i Q i ∈R 3 ,i=1,Λ,m} (1)

[0062] Where m is the initial holographic number.

[0063] The target holographic data is expressed by the following formula:

[0064] U={U i U i ∈R 3 ,i=1,Λ,n} (2)

[0065] Where n is the target holographic data volume.

[0066] The least mean square method is used to calculate all adjacent data pairs (U i ,Q i )'s rotation matrix parameter P and translation matrix parameter S, and then get:

[0067]

[0068] Among them, E(P,S) is the error value.

[0069] When the error value E is minimized, equation (3) is obtained, and the data registration process is completed.

[0070] In this embodiment, after the registration is completed, the registered data is subjected to noise reduction processing. Specifically, in this embodiment, the coordinates of the kth data point are set to C k (x k ,y k ,z k ), this point and the random point C j (x j ,y j ,z j ) is:

[0071]

[0072] For the mean distance s between each data point and the random point, we have:

[0073]

[0074] The standard deviation of the distance between each data point and the random point is:

[0075]

[0076] The multiple of the standard deviation is set to nσ, the number of adjacent data points is set to t, and nσ and t are used as input thresholds. When the mean distance between a data point and t adjacent data points in the cellar 3D laser holographic data is within the interval (θ-σ·nσ,θ+σ·nσ), the data point is retained, otherwise the data point is deleted to complete the noise reduction process.

[0077] After the noise reduction process is completed, this embodiment uses the human eye visual space frequency analysis method to compress the cellar three-dimensional laser holographic data after the registration and noise reduction process, thereby improving the efficiency of the model.

[0078] Specifically, in this embodiment, data compression processing is achieved by constructing a human eye contrast sensitivity function (CSF) model, and the specific model structure is:

[0079]

[0080] in, The color model of the human eye, is a brightness contrast sensitive visual feature model, is the visual spatial frequency of the human eye, and c1, c2, d1, d2, a1, and a2 are chromaticity parameters.

[0081] for Then we have:

[0082]

[0083] Among them, K is the number of pixels of the grating holographic image, m is the stripe pixel of the grating holographic image, and δ is the viewing angle of the human eye, specifically: D is the width of the grating holographic image, and L is the distance between the human eye and the grating holographic image.

[0084] After constructing the CSF model, the processed holographic data is converted into the three-primary color space, and the converted image is decomposed into brightness images corresponding to the three primary color components. The brightness images are then block processed and discrete cosine transformed to obtain spectral coefficients. The CSF model is used to quantize and encode the spectral coefficients to obtain a compressed brightness image data stream. The compressed brightness image data stream is inversely decompressed, and based on the three-primary color space features, the final three-dimensional laser holographic image of the cellar is obtained after sufficient matching.

[0085] Furthermore, in this embodiment, the assembled concrete formwork 1 adopts a stainless steel formwork, and the amount of concrete is calculated through drawings; the assembled concrete formwork 1 reserves a distance of 20-30 mm on the four end sides of the assembled pit bottom ditch according to the length and width of the pit.

[0086] Further, in this embodiment, after the assembled concrete pit bottom channel is positioned and installed, it is fixed and supported by a clamp supported by the steel bar 7. The structure of the steel bar 7 and the spring 8 is as shown in FIG. Figure 4 shown.

[0087] Further, in this embodiment, the steel bar 7 and the spring 8 are fixedly connected to the pit bottom ditch ring beam; a groove is provided on the side wall of the pit bottom ditch, and the specific structure is as follows: Figure 5 shown.

[0088] like Figure 6 As shown, this embodiment also discloses an assembled concrete pit bottom trench construction system, including: a three-dimensional model building module 11, a concrete template construction module 21, a concrete demoulding installation module 31 and a pit bottom trench construction module 41;

[0089] The three-dimensional model building module 11 is used to build a three-dimensional model according to the bottom ditch and size of the assembled concrete pit;

[0090] The concrete formwork construction module 21 is used to customize the assembled concrete formwork 1 according to the three-dimensional model and the size of the pit bottom branch ditch 3 made of aluminum plate, and fix it with a formwork clamp 4, reserve two holes 5 at the assembled concrete short side 6 of the assembled concrete 2, and then introduce the assembled concrete 2 into the assembled concrete formwork 1;

[0091] The concrete demoulding and installation module 31 is used to demould and install the assembled concrete 2, connect the spring 8 and the steel bar 7 and put them into the reserved hole 5, and reserve the hole in advance when pouring the cellar well ring beam;

[0092] The cellar bottom ditch construction module 41 is used to relax the compressed spring 8 after precise positioning, so that the steel bar 7 enters the reserved opening 5, the assembled cellar bottom ditch is connected with the opening 5 reserved in the cellar ring beam, and a prepared aluminum plate is glued to the aluminum plates in the assembled cellar bottom ditch at both ends with acrylic AB glue to form a whole, thus completing the cellar bottom ditch construction.
