Description

Technical Field

[0001] This invention relates to the field of building technology, and in particular to a mold and construction method for integral slope casting of foamed lightweight soil. Background Technology

[0002] Due to the presence of soft soil subgrades, foamed lightweight soil is often used as subgrade filler to reduce subgrade settlement. When the road has a certain slope, because foamed lightweight soil has high fluidity, it cannot be directly poured to form a top slope. Therefore, the top surface of the foamed lightweight soil needs to be poured in layers and sections. After the foamed lightweight soil hardens, concrete is poured on top to stabilize the slope. This construction method has the following shortcomings:

[0003] (1) Pouring concrete on the top surface of foamed lightweight soil is a complicated process, and the segmented pouring of foamed lightweight soil increases the amount of formwork work.

[0004] (2) The construction period was extended by waiting for the top layer of lightweight foamed soil to harden before pouring concrete.

[0005] (3) The cost of concrete is much higher than that of foamed lightweight soil, and the amount of formwork work increases, which increases the project cost;

[0006] (4) The concrete soil layer poured on the top layer is relatively thin and prone to cracking, making it difficult to guarantee the quality of the project. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention proposes a self-locking mold and its construction method for pouring foamed lightweight soil top slopes. This mold enables one-step pouring and forming of foamed lightweight soil top slopes, avoiding the need for step-by-step pouring and the increase in formwork work, thus optimizing the construction process and improving construction efficiency.

[0008] To achieve the above-mentioned technical objectives, the present invention employs the following technical means:

[0009] A self-locking mold for pouring foamed lightweight soil on a sloping surface, comprising:

[0010] The casting mold body, with guide rails installed on the inner side of its side mold and an opening at the top, also includes:

[0011] A constraint assembly, connected to the guide rail on both sides, forms a constraint plane above the inner cavity of the casting mold. The slope of the constraint plane matches the slope of the slope to be cast. The constraint assembly is a roller shutter type constraint assembly, comprising:

[0012] Curtains made of flexible materials;

[0013] A curtain pivot is located at one end of the inner cavity of the casting mold body, and the two ends of the curtain pivot are rotatably connected to the casting mold body;

[0014] The fixing part is located at the other end of the inner cavity of the casting mold body;

[0015] One end of the curtain is wound around the curtain shaft, and the other end is provided with a detachable fastening unit for connecting and fixing to the fixing part.

[0016] A drive assembly is used to drive the curtain pivot to rotate around its own axis, thereby raising and lowering the curtain.

[0017] When the curtain is unfolded, the two sides of the curtain are sealed with the guide rail groove of the guide rail, and the other end of the curtain is sealed with the fixing part through the detachable fastening unit to prevent the slurry from leaking from the gap between the curtain and the casting mold body during pouring.

[0018] The driving component includes:

[0019] Joystick;

[0020] The fastener, including a snap-fit ​​base and a cross-shaped snap-fit, is fixed to the side mold of the casting mold body;

[0021] The center of the rocker arm is a fixed spindle, and the bottom of the fixed spindle is provided with a cross-shaped groove that matches the shape of the cross-shaped buckle. The outer side of the fixed spindle is connected to the drive gear seat through the rocker arm bearing. The drive gear is fixedly connected to the drive gear seat, and the rocker arm handle is installed on the drive gear seat.

[0022] Driven gears are installed at both ends of the curtain shaft, and the driven gears mesh with the driving gears.

[0023] The curtain surface is wrapped with rubber edging on both sides. The rubber edging is embedded in the guide rail groove. When the curtain surface is subjected to outward force during pouring, the rubber edging can be locked by the guide rail, forming a self-locking mechanism.

[0024] The cross-section of the rubber edging is trapezoidal, and the cross-section of the guide rail groove is a right trapezoid. The length of the long base of the guide rail groove is greater than the length of the long base of the trapezoidal cross-section of the rubber edging, and the length of the short base of the guide rail groove is shorter than the length of the short base of the trapezoidal cross-section of the rubber edging.

[0025] The detachable locking unit is a strip-shaped airbag with an inflation port.

[0026] The fixing part is a strip-shaped slot, and the strip-shaped airbag is set in the strip-shaped slot. After being inflated, it can be locked in the strip-shaped slot and fill the gap between the strip-shaped slot and the intersection of the guide rail and the front end of the casting mold body to prevent leakage of foamed lightweight soil slurry.

[0027] This invention further discloses a construction method suitable for pouring concrete on the top slope of foamed lightweight soil, based on the self-locking mold used for pouring concrete on the top slope of foamed lightweight soil, comprising the following steps:

[0028] Step 1: According to the design requirements, use topographic instruments to measure and determine the starting and ending points of the slope to ensure accuracy; construct the formwork based on the construction drawings, including the side formwork, the rear end of the casting mold body, and the front end of the casting mold body;

[0029] Step 2: Install the guide rails on the side template according to the designed slope angle, and use a laser level to check the flatness and height difference of the guide rails. Insert the two sides of the curtain into the guide rail grooves, and spread the curtain to the corresponding position. When the curtain reaches the corresponding position, inflate the strip-shaped airbags so that the strip-shaped airbags completely fill the gaps between the strip-shaped slots and the intersection of the guide rails and the front end of the casting mold body, and fit tightly to prevent the leakage of foam lightweight soil slurry. Check the stability of the curtain again to ensure that it is not affected by construction disturbance.

[0030] Step 3: Based on the slope dimensions, design strength, and pouring thickness, prepare foamed lightweight soil slurry and measure its wet density and flow value. The number and frequency of measurements should meet the specifications. Use a delivery pump to pour the foamed lightweight soil outside the coverage area of ​​the curtain. Construction personnel should observe the flow state of the foamed lightweight soil slurry in real time to ensure that it is evenly filled into the pouring mold.

[0031] Step 4: According to the design requirements, cover and moisturize in time. According to the curing time of the foam lightweight soil, wait for it to fully cure. In the final stage of curing, roll up the curtain by rotating the curtain shaft and remove the entire restraint assembly from the casting mold body.

[0032] Step 5: Clean the surface of the mold, check for damage, and then store the constraint components in the designated location to prepare for the next use; check the internal quality and stability of the ramp with tools and equipment to ensure that it fully meets the engineering quality requirements. Beneficial effects

[0033] Compared to the traditional layered and segmented casting method, this mold has the following significant advantages when constructing sloping structures:

[0034] 1. Simplified and innovative process: This invention realizes a one-step casting design, avoiding the increase in the amount of formwork and the need for step-by-step casting, optimizing the construction process and improving construction efficiency.

[0035] 2. Optimized construction cycle: The present invention adopts a one-step pouring method, which effectively avoids the connection time of step pouring and effectively shortens the construction cycle.

[0036] 3. Cost reduction: The roller shutter-shaped ramp casting mold of the present invention eliminates the need to pour concrete on the top surface, and at the same time reduces the amount of formwork work, thereby significantly reducing the cost of concrete and formwork work.

[0037] 4. Improved engineering quality: This invention allows slopes to be integrally cast from foamed lightweight soil, thus improving engineering quality. Attached Figure Description

Implementation

[0057] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0058] This invention aims to solve the technical problem of pouring foamed lightweight soil on a sloping top surface. During the pouring of the foamed lightweight soil on a sloping top surface, a specially designed guide rail is installed on the side mold, and a slot is installed on the front end of the pouring mold body. The curtain is then inserted into the guide rail slot and fixed. A specially designed strip-shaped airbag is installed at the bottom of the curtain. After installation, the strip-shaped airbag is inflated, expanding and filling the strip-shaped slot, achieving a fixing and sealing effect. Foamed lightweight soil is then poured. Based on the structure design of the rubber-edged side of the curtain, the mold achieves self-locking during pouring, preventing leakage of the foamed lightweight soil slurry. After pouring, once the foamed lightweight soil reaches a certain strength, the strip-shaped airbag is deflated, separating the bottom of the mold from the strip-shaped slot. Then, a fixing device and a rocker arm are installed. The driving gear at the lower part of the rocker arm meshes with the driven gear at the curtain's rotating shaft. Rotating the rocker arm retracts the curtain.

[0059] The mold for pouring foamed lightweight soil on a sloping surface, as described in this invention, consists of three parts: a specially designed guide rail, a specially designed curtain, and a recycling device. The specific structure is as follows:

[0060] 1. Curtain Design: To meet the design requirements of different slopes, curved or straight slope casting molds are designed. Fiberglass is used as the curtain material, possessing high strength, corrosion resistance, and tear resistance. This ensures close contact between the mold and the lightweight foamed soil, preventing deformation or damage. A smooth, non-stick coating is applied internally to ensure a smooth surface after casting and facilitate mold disassembly.

[0061] 2. Recycling Device: Gears are installed at both ends of the rotating shaft of the curtain. After the pouring is completed, the recycling device is removed. This device consists of two parts: a fixing device and a rocker arm. The fixing device is fixed to the template with rivets, and the rocker arm can be installed on the fixing device. The recycling device can be removed after use and can be reused, which is convenient and environmentally friendly.

[0062] 3. Guide rail: It can fit different top slope lengths and is fixed to the side formwork by rivets. It can prevent leakage of foam lightweight soil slurry. After use, it can be removed along with the side formwork and reused.

[0063] 4. Self-locking device for the guide rail: The roller shutter door guide rail adopts a special design. The cross-sectional shape of the guide rail groove is a right-angled trapezoid. The length of the long base is greater than the length of the long base of the trapezoidal cross-section of the rubber edging, while the length of the short base is slightly shorter than the length of the short base of the trapezoidal cross-section of the rubber edging. The edge of the curtain is wrapped with trapezoidal rubber. When laying the curtain, the rubber edging is inserted from the wider part of the guide rail groove, allowing the rubber edging to slide easily within the guide rail groove, facilitating the laying of the curtain along the guide rail. When pouring foamed lightweight soil, the curtain is lifted by the force, and the rubber edging at the edge is naturally pushed inward, where it is locked by the narrower inner track, creating a self-locking effect.

[0064] 5. Strip-shaped airbags and slots. Strip-shaped airbags are installed at the front end of the curtain. Strip-shaped slots are installed on the front end of the casting mold body. After the curtain is installed, the strip-shaped airbags are inflated to lock the front end of the curtain into the strip-shaped slots, filling the gaps between the strip-shaped slots and the intersection of the guide rail 5 and the front end 24 of the casting mold body, preventing leakage of foamed lightweight soil. Example

[0065] like Figure 1 The diagram shown is a structural diagram of the foamed lightweight soil integral slope casting mold when the curtain is retracted.

[0066] Figure 2 This is a structural diagram of the foamed lightweight soil integral slope casting mold when the curtain surface is laid out according to the present invention;

[0067] Figure 3 This is a schematic diagram of the curtain structure of the present invention. As can be seen, a guide rail 5 is installed on the side mold 19, and the rubber edging 4 of the curtain 1 is in the guide rail groove. A strip-shaped airbag 6 is installed at the head of the curtain 1. After the strip-shaped airbag 6 is inflated, it is fixed by the strip-shaped slot 22.

[0068] like Figure 4 The image shown is a side view of the present invention during the pouring of foamed lightweight soil.

[0069] like Figure 5 As shown, Figure 1 An enlarged view of the guide rail installation shows that the curtain 1 is wound around the curtain shaft 2, with the tail of the curtain connected to the curtain shaft 2. Driven gears 3 are installed at both ends of the curtain shaft 2. The curtain 1 has rubber edging 4 on both sides, and a strip-shaped airbag 6 is installed at the head of the curtain 1. When the curtain 1 is laid out, the rubber edging 4 is inserted into the guide rail groove of the guide rail 5.

[0070] like Figure 6 As shown, after the curtain 1 is laid out, the curtain pivot 2 is exposed.

[0071] like Figure 7 The image shown is an enlarged view of the pumped lightweight soil section. During pouring, the delivery pump 20 pours the soil outside the covered portion of the curtain 1.

[0072] like Figure 8 The image shown is an enlarged view of the strip-shaped airbag and the strip-shaped groove. It can be seen that during casting, the strip-shaped airbag 6 is fixed by the strip-shaped groove 22, and the strip-shaped groove 22 is fixed to the front end 24 of the casting mold body by the groove rivet 23.

[0073] like Figure 9 The diagram shows the fixture. The wooden buckle base 8 is fixed to the side mold 19 by four base rivets 10, and a cross-shaped buckle 9 is nailed to the buckle base.

[0074] like Figure 10 The diagram shows a rocker arm. In the center is a fixed spindle 12 with a cross-shaped groove 11 engraved on it. A rocker arm bearing 13 is fitted around the fixed spindle 12. A drive gear seat 16 is fitted around the rocker arm bearing 13. The drive gear 14 is welded to the drive gear seat 16 as one piece. A rocker arm handle 15 is installed on the drive gear seat.

[0075] like Figure 11 The diagram shows the guide rail. The guide rail 5 can be installed on the side mold 19 by rivets 20. When the curtain 1 is installed, the rubber edging 4 of the curtain 1 is inserted into the guide rail groove of the guide rail 5.

[0076] like Figure 12 The diagram shows a strip-shaped slot 22. The strip-shaped slot 22 can be installed on the front end 24 of the casting mold body by rivets 23. When the curtain 1 is installed, the strip-shaped airbag 6 is inflated so that the strip-shaped airbag 6 is stuck in the strip-shaped slot to fix the curtain 1.

[0077] like Figure 13The diagram shows the curtain structure. The curtain 1 is connected to the mold shaft 2. Driven gears 3 are provided at both ends of the mold shaft 2. The two sides of the curtain 1 are wrapped with rubber edging 4. A strip-shaped airbag 6 is installed at the head of the curtain 1. Inflation ports 7 are installed on the upper sides of both ends of the strip-shaped airbag 6. The dashed box shows the state of the strip-shaped airbag 6 after inflation.

[0078] like Figure 14 The diagram shown is a demonstration of the device's recovery mechanism. The rocker arm is placed diagonally under the driven gear 3, so that the driven gear 3 meshes with the driving gear 14. Then, the cross-shaped buckle 9 is connected to the cross-shaped groove 11 under the rocker arm, so that the rocker arm handle 15 can be slowly rotated and the curtain 1 can be rolled up at a uniform speed.

[0079] like Figure 14 As shown, the rubber edging 4 is inserted into the guide groove of the guide rail 5. When the casting is performed, the force is directed outwards, and the rubber edging 4 is held in place by the outside of the guide rail 5, as shown. Figure 16 The self-locking mechanism is shown.

[0080] like Figure 17 The diagram shown illustrates the working principle of the strip-shaped airbag. After the strip-shaped airbag 6 is inflated, it will be locked in the strip-shaped slot 22 to fix the curtain 1, while filling the gap between the guide rail 5, the strip-shaped slot 22, the side mold 19 and the front end 24 of the casting mold body.

[0081] like Figure 18 The image shown is an enlarged view of the gap between the strip-shaped airbag 6 filling the guide rail 5, the strip-shaped slot 22, the side mold 19, and the front end 24 of the casting mold body.

[0082] The present invention discloses the construction steps of a self-locking mold for pouring foamed lightweight soil on a sloping top surface:

[0083] 1. Formwork erection: After the lower layer of lightweight foamed soil has hardened, use topographic instruments to measure and determine the starting and ending points of the slope to ensure accuracy. Then, erect the formwork (side formwork, rear end of the casting mold body, and front end of the casting mold body) based on the construction drawings.

[0084] 2. Mold Assembly and Positioning: Install guide rails 5 on the side mold 19 according to the designed slope angle, and install strip-shaped slots 22 on the front end 24 of the casting mold body. Use a laser level to check the flatness and height difference of the guide rails. Then, ensure that the air inlets 7 of the strip-shaped airbags are facing upwards. Insert both ends of the strip-shaped airbags 6 at the front end of the curtain 1 into the guide rails 5, and insert the rubber edging 4 of the edge of the curtain 1 into the guide rail grooves of the guide rails 5. Lay the curtain 1 to the corresponding position, inflate the strip-shaped airbags 6, so that the strip-shaped airbags 6 are locked by the strip-shaped slots 22, fixing the curtain 1. At the same time, the gaps between the guide rails 5, strip-shaped slots 22, side mold 19 and the front end 24 of the casting mold body are closed to prevent leakage of foamed lightweight soil slurry during casting and to ensure a tight fit. Check the stability of the curtain 1 again to ensure that it will not shift due to vibration during the casting process.

[0085] 3. Preparation and pouring of foamed lightweight soil: Based on the slope dimensions, design strength, and pouring thickness, prepare foamed lightweight soil slurry 20 and determine its wet density and flow value. Use a delivery pump 18 to pour the slurry from the bottom of the mold. Construction personnel should monitor the flow of the foamed lightweight soil slurry 20 to ensure that it is evenly filled into the interior of the curtain 1.

[0086] 4. Curing and Mold Removal: To prevent cracks in the foamed lightweight soil, it should be covered with a film and kept moist in a timely manner. Depending on the curing time of the foamed lightweight soil, wait for it to fully cure. In the final stage of curing, when releasing and recovering the gas from the strip-shaped airbag 6, first position and install the fixing device. Use rivets 10 to fix the buckle base 8 to the side mold 19. Next, install the rocker arm. Insert the rocker arm diagonally under the driven gear 3 so that the driven gear 3 meshes with the driving gear 14. Then connect the cross-shaped buckle 9 to the cross-shaped groove 11 under the rocker arm. The rocker arm handle 15 can then be slowly rotated to uniformly roll up the curtain 1.

[0087] 5. Post-processing: Clean the surface of the mold, check for damage, and then store it in the designated location to prepare for future use. Use professional tools and equipment, such as acoustic testing, to check the internal quality and stability of the ramp to ensure that it fully meets the engineering quality requirements.

[0088] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any simple modifications and equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.

[0089] The technology and methods used in this new mold not only simplify the traditional construction process, but also improve construction quality and efficiency, and have great application prospects.
