Description

Technical Field

[0001] The invention relates to the technical field of surge tank construction, and in particular to an assembled modular component of a surge tank flow hole and a construction method. Background Art

[0002] In the field of water conservancy and hydropower construction, especially in the construction of surge tank flow tunnel structures, many difficulties are often encountered. The traditional construction method has extremely limited operating space for operators during the steel bar installation and formwork installation of the main structure of the flow tunnel. Due to the small space of the flow tunnel structure, conventional construction methods are difficult to implement, resulting in low construction efficiency and difficulty in ensuring quality.

[0003] In addition, if conventional steel formwork is used to support the small circular flow paths of the surge tank flow hole and impedance hole, it will not only be costly, but also have many defects in practical applications. The customization of conventional steel formwork requires a lot of time and money, and it is heavy, the installation and disassembly process is complicated, and the requirements for construction machinery are high. At the same time, it is difficult to make the contact surface between the steel formwork and the concrete completely flat, which can easily lead to quality problems such as uneven appearance of concrete pouring, affecting the overall appearance and quality of the project.

[0004] During the construction process, due to the limitation of the operating space, the construction of the workers is extremely difficult, which not only increases the labor intensity, but also easily causes safety accidents. Moreover, how to carry out the concrete construction of the flow tunnel structure under the condition of limited working space at the bottom of the vertical shaft and the internal working space of the water diversion tunnel completed by the reverse construction method is a technical problem in the current water conservancy project construction. According to the structural characteristics of the flow tunnel, the safety and technical problems of the concrete construction of the surge tank structure include: the problem of no operating space for the workers to install the steel bars and formwork of the main structure of the flow tunnel during the concrete construction of the surge tank confined space flow tunnel structure, the uneconomical use of conventional steel formwork to support the small circular flow path of the surge tank flow tunnel and impedance hole, and the uneven appearance of the concrete pouring and other quality defects. Summary of the invention

[0005] The present invention provides an assembled modular component and construction method for a surge tank flow tunnel, aiming to solve the problem of lack of operating space for workers engaged in steel bar fabrication and installation of a flow tunnel main structure and template installation during concrete construction of a surge tank flow tunnel structure in a confined space.

[0006] The present invention is implemented by the following technical scheme: A construction method of a surge tank flow hole assembly module component comprises the following steps:

[0007] Make the template steel frame, and make the inner template steel frame that meets the size of the flow hole and anti-hole aperture according to the construction requirements of the surge tank excavation support;

[0008] Assembling glued wood molds, assembling glued wood molds on the surface of the inner mold steel frame to make inner molds for flow holes and impedance holes;

[0009] After the inner formwork is completed, the structural steel bars are tied outside the inner formwork, and then the structural steel bars and the inner formwork are connected as a whole to form a prefabricated component;

[0010] Prefabricated component hoisting operation: After retesting and cleaning the flow tunnel structure surface, the prefabricated components are hoisted into the flow tunnel;

[0011] When pouring concrete, a layer of mortar should be laid on the foundation surface or construction joints before the concrete is put into the warehouse.

[0012] In this scheme, glued wood formwork and PE plate steel bar welding support structure are used as the template for flow hole and impedance hole in the construction of the surge tank. The formwork is first supported and then tied and assembled into an integrated form. After the assembly is completed, comprehensive technical measures such as crane and manual lifting operations are adopted. This successfully solves the problem of no operating space for workers to make and install steel bars for the main structure of the flow hole and install the formwork during the concrete construction of the flow hole structure in the confined space of the surge tank. The conventional steel formwork is not economical to support the small circular flow path of the flow hole and impedance hole of the surge tank, and there are quality defects such as uneven appearance of the concrete pouring.

[0013] Laying a layer of mortar on the foundation surface or construction joint before the concrete is put into the warehouse can ensure good bonding between the new and old concrete construction joints.

[0014] Furthermore, after the glued wood formwork is assembled, a layer of PE board is nailed on the surface of the inner formwork.

[0015] Beneficial effect: This solution can ensure that the template surface is flat and smooth.

[0016] Furthermore, the PE plates are nailed in a plum blossom shape using fasteners.

[0017] Beneficial effect: Such an arrangement can improve the reliability between the PE board and the inner template.

[0018] Furthermore, before the prefabricated component is hoisted, the excavated opening of the flow passage is re-measured and cleaned.

[0019] Beneficial effect: It can ensure the smooth progress of the hoisting operation of the prefabricated components of the flow tunnel.

[0020] Furthermore, when the prefabricated components are hoisted, continuous hoisting operations are required. After the prefabricated components enter the flow passage, the prefabricated components are adjusted to make them centered and flush.

[0021] Beneficial effects: The lifting operation needs to be continuous to avoid garbage falling into the hole or animals entering the hole due to construction breaks, which may cause the structural surface in the hole to not meet the requirements of the drawings. The prefabricated components can be adjusted to make them centered and flush, thereby improving the construction quality.

[0022] Furthermore, before pouring concrete, the installation position, spacing, protective layer and size of the steel bars of the prefabricated components that have been hoisted are reviewed again.

[0023] Beneficial effects: This solution can ensure that the stability, rigidity and strength of the formwork meet the concrete construction load requirements and comply with the formwork design requirements.

[0024] Further, the treatment of concrete pouring includes the following methods:

[0025] Concrete is put into the warehouse, leveled and spread in sequence. Concrete is put into the warehouse vertically by a concrete pump truck, and the pouring operation surface is leveled manually. It is forbidden to use a vibrator to drag the paving material during the paving operation.

[0026] Concrete vibration, use a vibrating rod inserted into the concrete to vibrate, ensure that the concrete no longer sinks, no bubbles appear, and the surface shows floating slurry. The insertion points of the vibrating rod into the concrete are evenly arranged, moving point by point, and proceeding sequentially.

[0027] Beneficial effects: This solution can improve the quality of poured concrete and achieve internal and external beauty.

[0028] Furthermore, layered pouring is adopted in the concrete pouring process.

[0029] Beneficial effects: This solution can ensure the density and quality of concrete pouring.

[0030] A pressure regulating shaft flow hole assembled modular component includes a template steel frame body and a plywood body arranged on the outer surface of the template steel frame body, the outer surface of the plywood body is provided with a PE board body, the plywood body and the PE board body are laid on the outer surface of the template steel frame body, and are used to support and limit the template steel frame body.

[0031] Beneficial effects: The assembled module components in this scheme can be prefabricated, which is convenient for later lifting and reduces the difficulty of construction. At the same time, the assembled module components of this scheme have good structural strength and a more stable support effect on the flow tunnel.

[0032] Furthermore, a structural steel cage body is provided on the outer surfaces of the plywood body and the PE board body, and the structural steel cage body is connected to the plywood body and the PE board body by binding.

[0033] Beneficial effects: This solution can improve the structural strength of the entire component, thereby improving the supporting strength of the formwork, and the main body of the structural steel cage is connected to the main body of the plywood board and the main body of the PE board by binding. This connection method is highly operational and low in cost.

[0034] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0035] 1. The present invention adopts glued wood formwork and PE plate steel bar welding support structure as the template for the flow hole and the impedance hole for construction. Compared with the conventional customized steel formwork for support, it is simpler to operate, more reliable and safer to assemble, saves the steel formwork funds in terms of cost, shortens the time for customizing the steel formwork, and saves the construction period.

[0036] 2. Compared with the conventional steel bar installation and formwork installation in the flow tunnel of the surge tank, the self-made formwork and the steel frame of the flow tunnel structure are first supported and then tied and assembled into an integrated form. After the assembly is completed, a crane is used in conjunction with manual lifting operations, which effectively solves the problems of insufficient operating space and great operating difficulty for construction workers.

[0037] 3. By adding a layer of PE board on the glued wood formwork, the contact surface with the concrete is made flatter, smoother and easier to remove, which effectively improves the quality of concrete pouring and avoids quality defects.

[0038] 4. Compared with traditional steel formworks, the self-made inner formwork of the present invention is lighter in weight, easier to install and dismantle, and can be installed without the need for large-scale machinery, making it safer for construction workers to operate. The self-made inner formwork has higher accuracy when in use, and the size after forming has a small error with the design requirements. Compared with customized small steel formworks with a lower turnover and reuse rate, the self-made inner formwork reduces the use of steel, is more economical, green and environmentally friendly, and the formwork can be recycled, which has significant social benefits.

[0039] 5. Before construction, four-dimensional visual dynamic construction simulation is realized through the application of BIM software, and a four-dimensional progress construction simulation of the project is created. Different time unit intervals and different construction sequences are used to simulate and analyze the construction progress, which fully reflects the overall progress of the project and construction simulation drills, and realizes a full range of simulations from visual dynamic construction simulation to resource allocation and process flow. At the same time, due to the small space on the construction site, the overall structure is assembled before construction and hoisted after assembly, avoiding the problem of inconvenience in construction due to small space.

[0048] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0049] Example 1

[0050] like Figure 1-Figure 5 As shown, this embodiment 1 provides a construction method for a surge tank flow hole assembly module component, comprising the following steps:

[0051] Make the template steel frame, and make the inner template steel frame that meets the size of the flow hole and the anti-hole aperture according to the requirements of the pressure-regulating shaft excavation and support construction; in this embodiment, according to the requirements of the pressure-regulating shaft excavation and support construction, after the excavation interface and the main structure of the flow hole are completed, only 200mm of operating space is reserved. In order to ensure that there is enough operating space for the installation of steel bars and templates, it is necessary to prefabricate steel components in the steel bar processing plant in advance.

[0052] The inner form steel frame of the flow tunnel is bidirectionally tied with C25 steel bars, with a longitudinal steel bar spacing of 120mm and annular steel bar spacing of 500mm. The supporting steel bars in the tunnel are staggered and reliably welded to the main bars.

[0053] The glued wood mold is assembled on the surface of the inner mold steel frame to make the inner mold for the flow hole and the impedance hole; in this embodiment, a 2440mm×1220mm×18mm glued wood mold is selected for assembly. During the assembly process, three people are used to lift it in the extension direction and fit it along the length direction of the template steel frame. When the template is spliced, 1.5cm rivets are used to fix the square wood inside;

[0054] After the glued wood formwork is assembled, a layer of PE board is nailed on the surface of the inner formwork to ensure that the inner formwork surface is flat and smooth. In this embodiment, the PE board is nailed in a plum blossom shape using fasteners. Specifically: Figure 3 As shown, the fastener is a rivet. In this embodiment, the specification of the PE board is 3000mm×1500mm×3mm. The PE board is nailed with 1.5cm rivets arranged in a plum blossom shape of 50mm×50mm to ensure that the template surface is flat and smooth.

[0055] After the inner formwork is completed, the structural steel bars are tied outside the inner formwork, and then the structural steel bars and the self-made inner formwork are connected as a whole to form a prefabricated component; in this embodiment, after the self-made inner formwork is assembled and the PE board is nailed, the entire surface should be checked to see if there are any uneven and smooth surfaces such as loose joints and hollow PE boards. If so, square wood or rivets should be nailed immediately. After the inspection of each surface is completed, the structural steel bars are directly tied or welded on the formwork surface. During the steel bar installation process, it is strictly carried out in accordance with the requirements of the construction drawings. After the steel bar structure is completed, it will enter the next process after acceptance;

[0056] Re-measurement and cleaning of the flow tunnel structural surface. Before the above-mentioned prefabricated component hoisting operation, the excavation opening of the flow tunnel is re-measured and cleaned to ensure the smooth progress of the prefabricated component hoisting operation of the flow tunnel. Specifically: the construction personnel clean up the garbage, branches, soil and rocks inside the opening. After the cleaning is completed, the surveying personnel use the total station to review the center line, position and excavation size of the opening, and make timely corrections to the places that do not meet the review requirements;

[0057] After the prefabricated component hoisting operation is completed, the prefabricated component is hoisted into the flow tunnel after the re-measurement and cleaning of the flow tunnel structure surface is completed. In this embodiment, when the prefabricated component is hoisted, continuous hoisting operation is required to avoid garbage falling into the interior and animals entering the hole due to construction intervals, causing the structure surface in the hole to not meet the requirements of the drawings; after the prefabricated component enters the flow tunnel, the prefabricated component is adjusted to make the prefabricated component centered and flush, to ensure the smooth lifting of the component and the centering and flushing of the component. Specifically: a 75t truck crane is selected, and 4 hooks are symmetrically hooked on the bottom plate steel bars of the prefabricated component. When the hoisting starts, 4 people hold it diagonally to ensure the smooth lifting of the component; when the component enters the hole, it is necessary to ensure that no personnel enter the hole. After the component enters the hole smoothly, the centering and flushing of the component are adjusted manually in cooperation with the truck crane;

[0058] Installation accuracy review: Before pouring concrete, recheck the installation position, spacing, protective layer and size of each part of the steel bars in the prefabricated components that have been hoisted; to ensure that the stability, rigidity and strength of the inner formwork meet the concrete construction load requirements and meet the formwork design requirements; recheck the bottom elevation, structural section size, verticality and surface flatness of the inner formwork according to the specifications;

[0059] Concrete pouring: Before the concrete is put into the warehouse, a layer of 2-3cm thick mortar of the same grade should be laid on the foundation surface or construction joints. The mortar should be laid evenly and smoothly without any gaps to ensure a good bond between the new and old concrete construction joints. In this implementation, the concrete mix ratio, slump and pouring speed should be strictly controlled during the concrete pouring process. The layered pouring method should be adopted during the concrete pouring process to ensure the density and quality of the concrete pouring.

[0060] The process of pouring concrete in this embodiment includes the following methods:

[0061] Concrete is put into the warehouse, leveled and spread in sequence. Specifically: concrete pump truck is used to put concrete into the warehouse vertically, and the pouring operation surface is leveled manually. Vibrator rods are prohibited from being used to drag and spread materials during paving operations.

[0062] Concrete vibration: insert a vibrating rod into the concrete to make sure that the concrete does not sink, bubbles do not appear, and the surface shows floating slurry. The insertion points of the vibrating rod into the concrete are evenly arranged, moved point by point, and carried out in sequence without omission, so as to achieve internal solidity and external beauty;

[0063] Inspection of the concrete pouring process. During the concrete pouring process, formwork workers and reinforcement workers must strengthen inspection and maintenance to ensure that the reinforcement and embedded parts do not shift, the formwork does not deform, and any abnormal situation is handled in a timely manner. After the concrete pouring is completed, the formwork shall be removed after it reaches the specified strength. The formwork after removal shall be cleaned and maintained for the next turnover use.

[0064] Before construction, four-dimensional visual dynamic construction simulation is realized through the application of BIM software, and a four-dimensional progress construction simulation of the project is created. Different time unit intervals and different construction sequences are used to simulate and analyze the construction progress, which fully reflects the overall progress of the project and construction simulation drills, and realizes all-round simulation from visual dynamic construction simulation to resource allocation and process flow.

[0065] Example 2

[0066] Combination Figure 2-Figure 5As shown, the difference between this embodiment and embodiment 1 is that this embodiment provides a pressure regulating shaft flow hole assembled modular component, including a template steel frame body 1 and a plywood body 2 arranged on the outer surface of the template steel frame body 1, and the outer surface of the plywood body 2 is provided with a PE board body 3, and the PE board body 3 is nailed in a plum blossom shape of 50mm×50mm with 1.5cm rivets to ensure that the template surface is flat and smooth.

[0067] The plywood main body 2 and the PE board main body 3 are laid on the outer surface of the formwork steel frame main body 1 to support and limit the formwork steel frame main body 1.

[0068] A structural steel cage body 4 is provided on the outer surface of the plywood body 2 and the PE board body 3, and the structural steel cage body 4 is connected to the plywood body 2 and the PE board body 3 by binding, that is, the structural steel cage body 4 and the plywood body 2 and the PE board body 3 can be fixed by binding with iron wire or steel wire. This connection method is simple and has low construction cost.
