Description

Technical Field

[0001] The present invention relates to the field of glass breakwaters, in particular to a glass breakwater and a construction method thereof. Background Art

[0002] A glass breakwater is a new type of breakwater, which is composed of tempered laminated glass, side columns, middle columns and their fixed bases. The side columns and middle columns are made of aluminum alloy and are fixed on the upper part of the embedded parts of the concrete breakwater foundation to reinforce the whole glass breakwater. Glass breakwaters are often set at landscape rivers and landscape seawalls. Generally, the designed water retaining height does not exceed 1.5 meters. They are suitable for the reinforced concrete foundation of dikes. Usually, they are used as safety fences. During the flood season, they can resist the impact and invasion of river and lake water flows, have strong water pressure resistance and good waterproof effect; they are beautiful and generous, with various colors and good transparency. During the non-flood season, they do not affect the viewing effect of citizens.

[0003] The foundation for fixing the glass breakwater is a reinforced concrete foundation, which is a rigid foundation. In order to adapt to the uneven settlement of the foundation, settlement joints need to be arranged at fixed intervals in the concrete foundation. However, in the existing design and construction processes in China, the setting of the settlement joints of the glass breakwater is often ignored. The glass breakwater is made of glass with a fixed size, and the construction across the joints is carried out on the settlement joints of the concrete foundation. When the concrete foundation settles, the glass breakwater across the joints is prone to breakage.

[0004] Common anti-seepage materials for the existing settlement joints include copper water stop materials, rubber materials, asphalt fir wood boards, etc. Among them, the copper water stop material is a rigid material, with poor ability to adapt to the settlement deformation of the foundation. Moreover, copper and aluminum welding are dissimilar metals, and the welding difficulty is large. During welding, due to different welding temperatures, it is easy to cause burns to the aluminum alloy side columns, forming cavities. Therefore, the anti-seepage property at this part of the glass breakwater cannot be guaranteed. When using a rubber water stop belt, although it can adapt to the settlement deformation of the foundation, it cannot be closely connected with the aluminum alloy side columns. After the settlement of the concrete foundation, the gap increases, and the anti-seepage performance cannot be guaranteed. The asphalt fir wood board can make the glass breakwater adapt to the settlement of the concrete foundation, but the fir wood board cannot be closely attached to the aluminum alloy side columns, and it cannot meet the anti-seepage requirements. Even if the outer surfaces on both sides are sealed with asphalt mortar, the asphalt is prone to aging and falling off due to being exposed outside all year round. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a glass breakwater and a construction method thereof. During construction, a settlement joint is set at the glass breakwater, and the settlement joint of the glass breakwater is consistent with the settlement joint of the concrete foundation, so as to prevent the breakage of the glass breakwater when the lower concrete foundation settles and deforms.

[0006] To solve the above technical problems, the technical solution adopted by the present invention is: A glass wave breakwater, comprising multiple groups of single - panel glass wave breakwaters. Each group of single - panel glass wave breakwaters is arranged on a corresponding single - panel concrete foundation. A first settlement joint is provided between the single - panel glass wave breakwaters, and a second settlement joint is provided between the single - panel concrete foundations. The first settlement joint and the second settlement joint coincide on the vertical plane. The first settlement joint is filled with a polyurea grouting liquid, and the polyurea grouting liquid forms a polyurea elastomer after solidification.

[0007] The single - panel glass wave breakwater includes side columns on the left and right. Multiple groups of middle columns are arranged at intervals between the side columns. Tempered glass is installed between the side column and the middle column, and between the middle columns.

[0008] On the opposite faces of the side columns on the left and right of the first settlement joint, E - shaped strips are welded at intervals from top to bottom. The material of the E - shaped strip is the same as that of the side column.

[0009] Bases are fixed at the bottom ends of the side columns and the middle columns. The bases are placed on the embedded bottom plates on the single - panel concrete foundation and fixed by embedded bolts.

[0010] The tempered glass of the single - panel glass wave breakwater consists of fixed - size tempered glass and adjustable - size tempered glass. The length of the single - panel glass wave breakwater is the same as the length of the single - panel concrete foundation.

[0011] The bottom of the tempered glass is sealed with a sealing strip between the single - panel concrete foundation.

[0012] A construction method of a glass wave breakwater includes the following steps: Step 1: Customize the tempered glass according to the size of the single - panel concrete foundation so that the length of the single - panel concrete foundation is the same as the total length of the combined multiple tempered glasses. Step 2: Install and fix the embedded components. Step 3: Pour the concrete foundation. Step 4: Install the glass wave breakwater, leaving a first settlement joint between the single - panel glass wave breakwaters; the bottom layer of the single - panel glass wave breakwater is connected to the single - panel concrete foundation with a sealing strip. Step 5: Seal the front and back sides of the first settlement joint, then pour the polyurea grouting liquid. The polyurea grouting liquid forms a polyurea elastomer after solidification, and the polyurea elastomer and the E - shaped strip fill the first settlement joint.

[0013] In Step 4, before installing the glass wave breakwater, sandblast and weld the E - shaped strips on the side columns at the first settlement joint; the upper and lower E - shaped strips on both sides are arranged in a staggered and spaced manner.

[0014] In Step 5, before pouring, clean and remove dust from the side surface of the side column at the first settlement joint, and then paste and seal the two side surfaces with tape. Immediately after pasting, pour the polyurea grouting liquid. Since the first settlement joint is relatively high and the bottom pressure of the poured polyurea grouting liquid is relatively large, it is easy to cause the tape to crack. Therefore, additional tape is added at the bottom of the first settlement joint or a foaming sealing strip is used for plugging.

[0015] The present invention provides a glass breakwater and a construction method, having the following technical effects: 1) When the concrete foundation of the existing glass breakwater has a settlement joint, the upper glass breakwater will not be broken due to the deformation of the concrete foundation. By adjusting the size of the glass breakwater, a glass breakwater settlement joint is set at the settlement joint of the concrete foundation, and then the polyurea grouting liquid is filled between the two side columns of the glass breakwater, so that the polyurea grouting liquid is closely attached to the aluminum alloy side column and the concrete, which not only ensures the sealing of the glass breakwater, but also when the water level reaches the glass breakwater, the polyurea grouting liquid can play the role of resisting water pressure and preventing seepage, and can also adapt to the deformation caused by the settlement of the concrete foundation.

[0016] 2) Secondly, a new filling material - polyurea grouting liquid is used at the settlement joint. This liquid has strong filling ability and can be closely combined with the two side aluminum alloy columns after solidification. The polyurea elastomer can adapt to various settlement deformations and has outstanding anti-aging ability. Sandblasting is carried out on the aluminum alloy side columns on both sides of the glass breakwater settlement joint to increase the bonding ability between the polyurea grouting liquid and the surface of the side column, and E-shaped aluminum alloy is welded to increase the contact area with the polyurea grouting liquid. When the lower foundation concrete settles, the polyurea elastomer at the settlement joint will not generate cracks. When the water level rises to the glass breakwater, the polyurea grouting liquid at the settlement joint is closely attached to the aluminum alloy side column, with strong water pressure resistance and preventing river water from overflowing.

Detailed implementation mode

[0023] As Figures 1-4 shown, a glass wave - break wall includes multiple groups of single - panel glass wave - break walls 5, and each group of single - panel glass wave - break walls 5 is arranged on the corresponding single - panel concrete foundation 4. The single - panel glass wave - break wall 5 includes edge columns 1 (aluminum alloy) and middle columns 2 (aluminum alloy). The edge columns 1 are located at both ends of the single - panel glass wave - break wall 5, and the middle columns 2 are arranged in multiple groups at intervals in the middle section. Toughened glass 3 is installed between the middle columns 2 and between the edge column 1 and the middle columns 2. A first settlement joint 6 is provided between the single - panel glass wave - break walls 5. The concrete foundation includes multiple groups of single - panel concrete foundations 4, and a second settlement joint 7 is provided between the single - panel concrete foundations 4. The first settlement joint 6 coincides with the second settlement joint 7 and is on the same vertical plane, which can prevent the glass wave - break wall from cracking when the concrete foundation settles.

[0024] The first settlement joint 6 is filled with polyurea grouting liquid, and the polyurea grouting liquid forms a polyurea elastomer 8 after a period of time. This liquid has strong filling ability and can be closely combined with the aluminum alloy edge columns 1 on both sides after solidification. The polyurea elastomer can adapt to various settlement deformations and has outstanding anti - aging ability. Sandblasting is carried out on the aluminum alloy edge columns on both sides of the settlement joint of the glass wave - break wall to increase the bonding ability between the polyurea grouting liquid and the surface of the edge columns.

[0025] On the side of the edge column 1 on the left and right in the first settlement joint 6, an E - shaped strip 9 (aluminum alloy) is welded. The E - shaped strip 9 increases the contact area with the polyurea grouting liquid. When the lower - part foundation concrete settles, the polyurea elastomer at the settlement joint will not crack. When the water level rises to the glass wave - break wall, the polyurea grouting liquid at the settlement joint is closely attached to the aluminum alloy edge column, with strong water - pressure resistance and can prevent river water from overflowing.

[0026] The advantage of using aluminum alloy for the E - shaped strip 9: The aluminum alloy E - shaped strip and the edge column are both made of aluminum alloy, and the same metal is convenient for welding.

[0027] The bottom ends of the edge column 1 and the middle column 2 are both fixed with a base 10. The base 10 is placed on the embedded base plate 11 on the single - panel concrete foundation 4 and is fixed by the embedded bolts 12 on the single - panel concrete foundation 4.

[0028] The toughened glass 3 is divided into fixed-size toughened glass (a) and adjustable-size toughened glass (b). There are multiple pieces of fixed-size toughened glass (a) with the same size, and there is a single piece of adjustable-size toughened glass (b). The sum of the lengths of the multiple pieces of fixed-size toughened glass and the length of the adjustable-size toughened glass is equal to the length of a single concrete foundation 4. The previous glass wave breakwater was made of fixed-size glass and was constructed across the settlement joint of the concrete foundation. When the foundation settled, the glass wave breakwater across the joint was prone to breakage. The glass wave breakwater composed of fixed-size glass and adjustable-size glass makes the setting position of the first settlement joint of the glass wave breakwater coincide with the setting position of the second settlement joint of the concrete foundation.

[0029] A ternary ethylene propylene rubber sealing strip 13 is provided at the contact between the toughened glass 3 and a single concrete foundation 4. Advantage: The ternary ethylene propylene rubber sealing strip is a flexible material, which can fill the gap between the single-piece glass wave breakwater and the concrete foundation tightly, playing the role of anti-seepage and waterproofing.

[0030] The edge of the toughened glass 3 is wrapped with a frame 14.

[0031] A construction method for a glass wave breakwater includes the following steps: Step 1: Determine the size of a single concrete foundation 4 according to the construction drawings, and then customize the toughened glass 3 according to the size of the single concrete foundation 4. The customized toughened glass 3 can be a combination of fixed size and adjustable size, or all fixed size. In either case, the phenomenon of the toughened glass 3 straddling the second settlement joint 7 (the settlement joint of the concrete foundation) should be prevented.

[0032] Step 2: Before pouring the concrete foundation, place and fix the embedded bolts 12 and the embedded base plates 11 on the reinforcement bars or the formwork. The fixed positions of the embedded base plates 11 and the embedded bolts 12 match the single-piece fixed-size toughened glass and the adjustable-size toughened glass. After installation, pour the concrete foundation. A second settlement joint 7 is formed between single concrete foundations 4, and an asphalt fir board is provided in the second settlement joint 7.

[0033] Step 3: Before installing the glass wave breakwater, sandblast and weld the E-shaped aluminum alloy to the side columns 1 at the first settlement joint 6. After the concrete foundation strength reaches the design requirements, install the side columns 1 and the middle columns 2, and at the same time install the toughened glass 3. After installation, pour the polyurea grouting liquid into the first settlement joint 6.

[0034] Example 1 Taking the requirement of a single concrete foundation in the construction drawings as 13.5 m as an example, the specific implementation method is as follows: Step 1: Customize tempered glass according to the width of the concrete foundation: The width of a single concrete foundation 4 is 13.5m. Consult the tempered glass processing factory to customize the size, such as 3.5m (fixed size tempered glass a) + 3.5m (fixed size tempered glass a) + 3.5m (fixed size tempered glass a) + 3.0m (adjustable size tempered glass a) = 13.5m (single concrete foundation size). You can also customize the size of 2.7m (fixed size tempered glass a) × 5 = 13.5m (single concrete foundation size). Fixed size tempered glass and adjustable size tempered glass The division of tempered glass is mainly to make the length of the concrete foundation consistent with the total length of multiple tempered glass combinations. It is strictly forbidden to have a piece of glass spanning two concrete foundations, that is, the tempered glass wave-breaking wall cannot span the concrete foundation settlement joint, such as 3.5m (fixed size) + 3.5m (fixed size) + 3.5m (fixed size) + 3.5m (fixed size) = 14.0m> 13.5 (single concrete foundation size). This installation method will result in a piece of tempered glass spanning the concrete foundation settlement joint. When the concrete foundation settles, the tempered glass across the joint will crack and shatter.

[0035] Step 2: Installation and fixation of embedded parts: The installation and fixation position of the embedded components (embedded base plate 11, embedded bolts 12, etc.) should be compatible with the size of the tempered glass 3. It is strictly forbidden to have the size too large or too small. After the installation is completed, another surveyor should re-measure the length between the two embedded components and the axial position of the embedded steel plate to see if there is any deviation. If there is a deviation, it should be adjusted again. If there is no deviation, it should be welded to the foundation concrete reinforcement or tied to the formwork.

[0036] Step 3: pouring of concrete foundation of glass wave-breaking wall: pouring of concrete is carried out after the template is installed and reinforced and the embedded components are fixed. When pouring concrete, it is strictly forbidden to pour concrete directly onto the embedded base plate 11 and the embedded bolts 12 to prevent the displacement of the embedded components. When vibrating with the vibrating rod, it is also necessary to prevent the embedded parts from touching and causing displacement. The concrete at the bottom of the embedded base plate 11 should be manually vibrated and compacted to prevent hollowing of the concrete at the bottom of the base plate.

[0037] Step 4: Processing the aluminum alloy side column: The facade at the settlement joint of the side column 1 is sandblasted to increase the roughness of the surface and enhance the bonding force between the polyurea grouting liquid and the aluminum alloy surface. Then the E-type aluminum alloy strips are welded on the facade of the aluminum alloy side column. The E-type strips 9 on both sides are arranged in an alternating manner. The alternating arrangement of the E-type aluminum alloy strips can effectively absorb the displacement of the upper, lower, left and right sides caused by the concrete foundation, increase the contact area with the polyurea grouting liquid, and play a reinforcing support role in the polyurea elastomer 8 after the polyurea grouting liquid is poured and solidified, which can effectively resist the shrinkage of the polyurea elastomer when it is cold and the subsequent settlement of the concrete foundation, causing the polyurea elastomer and the aluminum alloy to crack. It is forbidden to weld the two facades of the side column together through the aluminum alloy strips to form a rigid connection to prevent the settlement of the concrete foundation from causing tearing damage to the side column. At the same time, when the water level rises to the glass wave-breaking wall, the polyurea elastomer together with the E-type aluminum alloy strips can effectively resist the water pressure and play a role in anti-seepage and anti-pressure.

[0038] Step 5: Install the side column 1 and the tempered glass 3 at the first settlement joint 6; after the concrete strength reaches the age requirement, the tempered glass 3, the column 1 and the middle column 2 are customized, the column 1 and the middle column 2 are installed, wherein the customized side column 1 and the middle column 2 are welded to the base 10 to form a whole, and then fixed to the bottom plate 11 of the concrete base by the embedded bolts 12. When hoisting a single glass wave-breaking wall (a single tempered glass 3 with a sealing frame 14), it should be noted that the length of the single adjustable glass wave-breaking wall is suitable for the length between the side column and the middle column on both sides of the single tempered glass wave-breaking wall, so that the single adjustable size glass wave-breaking wall can be smoothly installed. The bottom layer of the whole glass wave-breaking wall is connected to the single concrete foundation 4 with a sealing strip 13.

[0039] Step 6: Inject polyurea grouting liquid into the first settlement joint 6: Polyurea grouting liquid is an elastomeric substance generated by the reaction of isocyanate components and amino compound components. Polyurea grouting liquid can bond metal, concrete, brick walls, etc., and has good elasticity, strength, corrosion resistance, sealing and waterproof properties. Therefore, polyurea grouting liquid is used to inject the settlement joint of the glass wave-breaking wall.

[0040] Before perfusion, clean and remove dust from the side surface of the side column 1 at the first settlement joint 6, and then use tape 15 (select the width of the widened tape according to the width of the settlement joint) to paste and seal both side surfaces. After pasting, check whether the paste is firm. When pasting, choose a time period with a higher temperature during the day to avoid construction in winter to prevent the paste from being insecure. After pasting, the polyurea grouting liquid should be poured immediately. Since the first settlement joint 6 is relatively high, the bottom pressure of the poured polyurea grouting liquid is relatively large, and the tape is prone to cracking. Therefore, measures such as adding supplementary tape at the bottom and increasing the adhesive area of the tape can be taken to resist the bottom pressure of the poured polyurea grouting liquid. For the places where the bottom tape 15 cannot be sealed, a small amount of foamed sealing strips are used for plugging. It can be torn off the tape 15 only after the polyurea grouting liquid has cured into the polyurea elastomer 8. At this time, the polyurea elastomer 8 and the E-shaped strip (aluminum alloy) jointly act to fill the first settlement joint 6, which can not only adapt to the foundation deformation without cracking or damage, but also resist pressure and prevent seepage when the water level rises to the glass wave wall.
