Description

Technical Field

[0001] This invention relates to the fields of urban flood control engineering, water conservancy engineering and landscape architecture engineering, specifically to a conical column socket-type glass flood control wall and its construction method, which is suitable for water-retaining facilities in urban waterfront areas that have both landscape and flood control functions. Background Technology

[0002] Urban waterfront areas have dual requirements for flood control and scenic openness. Traditional flood walls, mostly constructed of reinforced concrete or masonry, are thick and visually enclosed, severely severing the connection between the city and the waterfront landscape, and occupying large amounts of land in the expensive urban core. Therefore, glass flood walls are increasingly being used, utilizing the excellent light transmittance of high-strength tempered glass to maintain visual transparency while fulfilling flood control functions, thus achieving an organic integration of flood control and landscape.

[0003] Currently, most glass flood control walls adopt a combination of equal-section columns (rectangular or I-shaped) and glass panels. Vertical slots are opened on both sides of the columns, and the glass panels are inserted into the slots and fixed with sealant or pressure strips. However, this type of structure still has the following shortcomings in practical applications: (1) The column cross-section design is unreasonable. The cross-section of the column with constant cross-section is determined by the maximum bending moment at the bottom. The top structure is too large, the material strength is not fully utilized, resulting in material waste and increased self-weight. Some schemes design the column as a variable cross-section, but only consider the optimization of structural stress, without systematically coupling the cross-section change with the installation process and sealing performance.

[0004] (2) Difficulty in glass insertion and sealing performance are difficult to achieve simultaneously. In existing glass flood control walls, the glass panels are usually sealed by elastic seals with uniform cross-sections after being inserted into the column slots. Since the cross-section of the sealing strip is consistent along the height direction, the sealing strip must provide a sufficiently large compression to ensure the sealing effect at the bottom where the water pressure is the greatest. However, this compression will cause a large insertion resistance when the glass is inserted. If the compression of the sealing strip is reduced to reduce the insertion resistance, the bottom sealing reliability will be insufficient. The existing structure cannot achieve the graded sealing requirement of "low insertion resistance, high bottom sealing pressure, and low top sealing pressure".

[0005] (3) Inconvenient replacement and maintenance of glass panels. Most existing glass panels are fixed with sealant or bolt strips. When replacing a single broken glass panel, the sealant needs to be removed or the strips need to be disassembled. The construction is complicated, the cycle is long, and it is easy to damage the adjacent glass and column surfaces.

[0006] (4) The pressure distribution of the seal is not optimized. The elastic seal between the column slot and the glass panel is uniform along the height direction. The physical law that the water pressure is distributed in a triangle along the height (large at the bottom and small at the top) is not taken into account. The bottom sealing pressure is insufficient while the top sealing pressure is redundant, resulting in low sealing efficiency and material waste.

[0007] Therefore, there is an urgent need for a new type of glass flood control wall structure that can achieve rapid installation and disassembly of glass panels, match sealing performance with water pressure distribution, and have high material utilization efficiency, while ensuring structural safety. Summary of the Invention

[0008] To address the aforementioned technical problems, this invention proposes a conical column-inserted glass flood control wall. The aim is to solve the technical problems of low material utilization of existing glass flood control wall columns, contradiction between glass insertion and sealing, inconvenience of replacement and maintenance, and mismatch between sealing pressure and water pressure distribution by changing the structure of the flood control wall.

[0009] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: A conical column-insertion type glass flood control wall includes: a foundation, which is set on the ground; a pre-reserved mounting slot on the foundation; multiple columns, evenly spaced and fixed on the foundation; the columns are conical along the height direction, and their cross-sectional dimensions gradually decrease from bottom to top; each column has a vertically formed mounting slot on its opposite inner surface, and the slot width of the mounting slot is consistent along the height direction; a glass panel, inserted into the mounting slot from the top of two adjacent columns, with the bottom of the glass panel inserted into the mounting slot; an elastic seal, located between the inner wall of the mounting slot and the glass panel, the compression of the elastic seal decreasing from bottom to top in the height direction, so that the sealing pressure at the bottom of the mounting slot is greater than the sealing pressure at the top, matching the triangular distribution of water pressure along the height; and a top pressure beam, detachably straddling the top of two adjacent columns and the glass panel between them.

[0010] Preferably, the cross-sectional thickness of the resilient seal decreases linearly from bottom to top along the height direction to create a stepped compression performance along the height direction.

[0011] Preferably, the elastic seal is formed by splicing or hot-melting processes to achieve a stepped compression performance along the height direction, with the bottom area of ​​the elastic seal using a high-compressibility material or structure and the top area using a low-compressibility material or structure.

[0012] Preferably, the elastic seal is provided in the mounting slot.

[0013] Preferably, the glass panel is made of tempered laminated glass.

[0014] Preferably, the top pressure beam is made of aluminum alloy or stainless steel and has an inverted U-shaped cross-section.

[0015] Preferably, the top pressure beam is connected to the column by bolts.

[0016] Preferably, a water-stop rubber pad is provided at the bottom of the top pressure beam where it connects to the glass panel or column.

[0017] Preferably, the foundation is a reinforced concrete strip structure or a pile cap; construction joints for columns are reserved on the foundation; and the columns are precast reinforced concrete components.

[0018] The advantages of this invention due to the adoption of the above technical solution are as follows: 1. High material utilization: The column adopts a tapered cross-section, and the cross-sectional dimensions match the bending moment distribution law generated by water pressure, avoiding the waste of excess material at the top of the column with uniform cross-section, which can save 15% to 30% of the column material usage.

[0019] 2. Convenient glass installation and removal: The socket groove is of uniform width, the compression of the elastic seal gradually changes along the height, the glass panel insertion resistance is uniform and the alignment is easy, no additional tools or lubrication are required; when disassembling, only the top pressure beam needs to be removed to pull the glass out from above, and the replacement of a single glass panel does not affect the adjacent panels.

[0020] 3. Precise matching between sealing pressure and water pressure distribution: The compression of the elastic seal decreases from bottom to top, and the bottom sealing pressure is greater than the top sealing pressure, which is consistent with the triangular distribution of water pressure along the height. This ensures high reliability in preventing leakage and makes reasonable use of sealing materials.

[0021] 4. Simple structure and fast construction: The elastic sealing component is installed as a whole, and the glass panel is directly inserted. The construction process is simple and the cycle is short, making it suitable for rapid renovation of urban waterfront areas and emergency flood control projects.

[0022] 5. Excellent landscape transparency: The tempered laminated glass panel has high light transmittance, and the tapered design of the columns makes the top cross section of the columns smaller, reducing the visual oppression and making the landscape effect better than traditional columns with equal cross section.

[0023] 6. Easy maintenance: Routine glass maintenance is convenient; simply disassemble and reassemble the various components without the need for complex machinery. Attached Figure Description

[0024] Figure 1 This is a schematic diagram of the overall structure of the conical column socket-type glass flood control wall implemented in this invention.

[0025] Figure 2 The cross-sectional views are for implementation of the present invention (corresponding to the bottom and top sections respectively). Detailed Implementation

[0026] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0027] See Figure 1 The diagram shown is a schematic representation of the overall structure of the conical column-inserted glass flood control wall according to an embodiment of the present invention. In this embodiment, the conical column-inserted glass flood control wall includes a foundation 1, columns 2, elastic sealing elements 3, glass panels 4, and a top pressure beam 6.

[0028] Foundation 1 is a reinforced concrete strip foundation or pile cap, set on the ground. A construction joint is reserved between foundation 1 and column 2 to facilitate the subsequent construction of column 2, so that column 2 and foundation 1 form an integral load-bearing component. Foundation 1 is reserved with an installation groove 11 for an elastic sealing element, and the groove depth is preferably 20mm.

[0029] The columns 2 are precast reinforced concrete components, arranged at intervals along the flood control axis, with a standard spacing of 1.5~2.5m. The columns 2 are tapered along their height, with their cross-sectional dimensions gradually decreasing from bottom to top. In this embodiment, the bottom cross-sectional dimensions of the column 2 are 300mm×300mm, the top cross-sectional dimensions are 150mm×150mm, and the height of the column 2 is 1.0~1.5m. Each column 2 has a vertically oriented socket 21 on its opposite inner surface. The width of the socket 21 remains consistent along the height direction, ranging from 20~50mm. The socket 21 is used to insert the glass panel 4.

[0030] The glass panel 4 is inserted into the receiving slot 21 from the top of the two adjacent columns 2, and the bottom of the glass panel 4 is inserted into the mounting slot 11.

[0031] An elastic seal 3 is disposed between the inner wall of the socket 21 and the glass panel 4. The compression of the elastic seal 3 decreases from bottom to top in the height direction, making the sealing pressure at the bottom of the socket 21 greater than that at the top, which matches the triangular distribution of water pressure along the height. In this embodiment, the elastic seal 3 is made of ethylene propylene diene monomer (EPDM) rubber, and its cross-sectional thickness varies gradually along the height direction: the bottom thickness is 18mm, the top thickness is 15mm, and the middle is linearly transitioned. When the thickness of the glass panel 4 is 20mm, the socket groove width is 44mm, then the compression of the elastic seal 3 on one side at the bottom is 6mm (compression rate 33%); the compression of the elastic seal 3 on one side at the top is 3mm (compression rate 20%). This achieves a graded sealing effect with high sealing pressure at the bottom and low sealing pressure at the top, matching the triangular distribution of water pressure along the height.

[0032] In the first embodiment, the elastic seal 3 is implemented using a gradual change in cross-sectional thickness: the cross-sectional thickness of the elastic seal decreases linearly from bottom to top along the height direction, being thicker at the bottom and thinner at the top. After the glass panel is inserted, the bottom generates a larger amount of compression and sealing stress, while the top experiences a smaller amount of compression. In another embodiment, the elastic seal 3 can be implemented using a gradual change in material properties: the elastic seal is formed by a splicing or hot-melting process to achieve a stepped change in compressibility along the height direction, with the bottom area using a high-compressibility material or structure and the top area using a low-compressibility material or structure. Both embodiments enable precise matching of the sealing pressure distribution with the triangular distribution of water pressure, while ensuring uniform insertion resistance of the glass panel along the entire height direction, avoiding localized jamming.

[0033] The top pressure beam 5 is made of aluminum alloy or stainless steel, with an inverted U-shaped cross-section, straddling the top of the column 2 and the glass panel 4. The top pressure beam 5 is bolted to the column 2, and a water-stop rubber pad is installed at the bottom of the beam. The top pressure beam 5 can be removed during non-flood seasons. When the glass panel 4 needs to be replaced, the top pressure beam 5 is removed, the broken glass is pulled out directly from above, a new glass is installed, and the top pressure beam is reinstalled.

[0034] Due to the adoption of the above technical solution, the present invention has high material utilization rate, convenient glass installation and disassembly, and precise matching between sealing pressure and water pressure distribution. The compression of the elastic seal decreases from bottom to top, and the bottom sealing pressure is greater than the top sealing pressure, which is consistent with the triangular distribution of water pressure along the height. This results in high reliability of seepage prevention and reasonable utilization of sealing materials.

[0035] The construction method in this embodiment includes the following steps: Step 1: Foundation Construction. Pour reinforced concrete foundation, reserving construction joints for column connections, and also reserving slots for installing elastic sealing components.

[0036] Step 2: Construct the column. The bottom of the column is rigidly connected to the foundation. The column is then poured, and a socket is reserved.

[0037] Step 3: Install the elastic seal. Insert the bottom of the elastic seal into the pre-drilled mounting slot in the foundation plate, and then insert the side of the elastic seal into the pre-drilled slot in the column.

[0038] Step 4: Install the glass panel. Slowly insert the tempered laminated glass panel into the slot from the top of the column. The elastic sealing strip will automatically compress and fit into place as the glass is inserted.

[0039] Step 5: Install the top pressure beam. Place the top pressure beam over the top of the column and the glass panel, secure it with bolts, and adjust the waterproof rubber pads to ensure a tight fit between the top surface of the glass panel and the top surface of the column.

[0040] The embodiments described above are for illustrative purposes only and are not intended to limit the scope of the invention. All equivalent changes and modifications made to the invention by those skilled in the art should fall within the scope of the appended claims.
