Description

Technical Field

[0001] The present invention belongs to the technical field of prefabricated inspection wells, and more specifically, relates to a cast-in-place strong and weak electricity inspection well template system and a construction method. Background Art

[0002] Traditional inspection well construction mostly uses wooden strips to form templates, standardized wooden templates and standardized steel templates. The wooden strips to form templates are semicircles composed of multiple line segments, and it is difficult to accurately adjust the height and thickness of the inspection well. The standardized templates need to customize multiple sets of templates according to different circular diameters, and cannot flexibly adapt to the needs of different heights and thicknesses; the size and shape of the traditional templates are fixed, and it is difficult to adapt to the needs of different construction scenarios. For example, the standardized steel template needs to be customized according to different circular diameters, and the scope of application is narrow. The turnover rate of traditional templates is low and the number of uses is limited. For example, the turnover rate of wooden strips to form templates is only about 5 times. The turnover rate of standardized wooden templates and standardized steel templates is also not high, and they are easily damaged during use. Due to the low turnover rate, the templates need to be frequently replaced and maintained during use, which increases the construction cost; traditional templates are mostly one-time use or have a limited number of reuses, resulting in serious material waste. For example, wooden strips to form templates are prone to leakage during use, requiring a large number of wooden strips, wasting forest wood resources; the installation and removal process of traditional templates is complicated and requires a lot of manpower to operate. For example, standardized steel molds are heavy, inconvenient to install, dismantle and carry, and increase the labor intensity of construction workers.

[0003] The prior art has a method of adjusting the height of the inspection well template by setting telescopic struts for lifting. However, there are problems with the thickness adjustment of the inspection well and the inability to ensure the strength of the inspection well. It is very easy to be unstable and prone to the risk of mold explosion. There is a method of quickly erecting the inspection well template by surrounding an inner mold tube and an outer mold tube, but the processing technology of the tube is relatively cumbersome and the concrete expansion and contraction after the material is fixed causes damage, resulting in a waste of labor and material costs. There is also a method of combining an outer steel ring and an inner steel ring to form a combination bolt for fixing and rapid erection and dismantling, but the height of the inspection well tube is difficult to adjust and the scope of application is relatively narrow. It is necessary to find a steel ring with a width corresponding to the actual height of the inspection well, and the steel ring itself is heavy, which is prone to safety accidents during the process of removing the template.

[0004] Therefore, there is an urgent need for an inspection well template device that can be quickly erected, reused and has high adjustment flexibility. Summary of the invention

[0005] In view of the above defects or improvement requirements of the prior art, the present invention provides a cast-in-place strong and weak electricity inspection well formwork system and construction method. The system includes a number of arc-shaped steel plates, rectangular stiffening steel plates, and maintenance supports with adjustable fasteners. By reasonably designing the steel plate modulus, a flexible and detachable steel formwork is assembled by splicing steel plates of a certain modulus. Through the flexible erection of the formwork, the height and thickness of the inspection well can be flexibly adjusted, so that the steel formwork actually required on site can be effectively spliced, can be quickly disassembled and assembled, and can be repeatedly turned over with extremely low loss rate. It is suitable for the construction of cast-in-place strong and weak electricity inspection wells. Especially in projects with different requirements for the height and thickness of inspection wells, it can better meet the construction needs and improve the construction quality and efficiency. The present invention can solve the problems that the adjustment of the height and thickness of the traditional inspection well formwork is not flexible enough, the formwork turnover rate is low, and material and labor are wasted.

[0037] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0038] (1) The present invention provides a cast-in-place strong and weak electricity inspection well template system and method. The system is equipped with a complete support system, making the template structure more stable. During the concrete pouring process, it can effectively resist the lateral pressure and keep the shape and position of the template unchanged, thereby ensuring that the quality of the cast inspection well meets the design requirements and reducing the quality problems and rework caused by template deformation; by designing the module of the template, the size and shape of the template have a certain standardization and uniformity, which is convenient for construction personnel to quickly understand and operate, and also convenient for the storage and transportation of the template, so as to achieve flexible assembly and disassembly of the template; construction personnel can quickly assemble and disassemble the template according to the specific size and shape requirements of the inspection well, without the need for complex tools and cumbersome operating steps, greatly improving construction efficiency and shortening the construction period; by adjusting the number of the first bottom template, the first upper template, the second bottom template, and the second upper template and adjusting the spacing between the sleeve-shaped outer mold assembly and the sleeve-shaped inner mold assembly through the detachable fastener, the flexible assembly and disassembly of the inspection well templates of different sizes can be achieved, and the height and thickness of the inspection well can be flexibly adjusted.

[0039] (2) The present invention provides a cast-in-place strong and weak current inspection well formwork system and method. The arc-shaped design of each panel enables it to fit closely to the circular structure of the inspection well. Whether it is the adjustment of height or thickness, it can maintain good adaptability and ensure that the shape and size of the concrete pouring meet the design requirements. The vertical and horizontal stiffening plates are arranged on the panel in a cross-section, which effectively enhances the rigidity and stability of the formwork, making it less likely to deform when subjected to the lateral pressure of the concrete, ensuring the construction quality and reducing the concrete pouring defects caused by the deformation of the formwork. The design of each connecting plate provides convenience for the detachable assembly of the formwork, so that the formwork can be quickly installed and disassembled according to the actual engineering requirements, improving the construction efficiency, and also facilitating the transportation and storage of the formwork, reducing the construction cost. The specific connection method and layout of the first vertical support panel and the first bottom foundation support plate, and the second vertical support panel and the second bottom foundation support plate enable the formwork to reasonably disperse and transmit force when subjected to force, avoiding damage caused by excessive local force and extending the service life of the formwork. The structural design of each formwork and the bolt connection method between the formworks not only ensure the strength and stability of the formwork, but also realize the convenient assembly and disassembly of the formwork, providing an efficient and reliable formwork support system for the construction of cast-in-place strong and weak current inspection wells.

[0040] (3) The present invention provides a cast-in-place strong and weak current inspection well formwork system and method. The design of the detachable fasteners allows the thickness of the inspection well to be flexibly adjusted according to actual engineering needs without replacing the entire formwork system, greatly improving the application range and utilization rate of the formwork and reducing construction costs. The coordination of the fastening bolts and the adjustment holes, as well as the tight fit between the fastening blocks and the formwork, ensures that the connection between the formwork components is stable and reliable, and can withstand greater lateral pressure during concrete pouring, ensuring that the formwork shape remains unchanged, thereby ensuring that the quality of the cast inspection well meets the requirements. The adjustment and fixing operations of the fasteners are simple and quick, and can be completed by simply loosening or tightening the fastening bolts, greatly improving construction efficiency and shortening the construction period.

[0041] (4) The cast-in-place strong and weak electricity inspection well formwork system and method of the present invention adopts steel formwork as the main material, and has the advantages of high strength, high rigidity, and long service life. The steel formwork can be spliced ​​arbitrarily and flexibly combined according to the different specifications of the inspection well to meet the diverse construction needs. When traditional formwork is processed on site, there are often problems such as serious material waste and difficulty in turnover. The formwork system of the present invention effectively solves these problems through standardized modular design and detachable connection methods, improves the turnover rate and utilization rate of the formwork, and achieves resource conservation and cost reduction. At the same time, the steel formwork has low loss and can be recycled, avoiding the waste caused by on-site processing of traditional formwork and reducing construction costs.

[0063] like Figure 7 As shown, the second aspect of the present invention provides a construction method for a cast-in-place strong and weak current inspection well template system, comprising the following steps:

[0064] S1: Prepare and transport templates and accessories, prefabricate a number of first bottom templates 111, first upper templates 121, second bottom templates 211, second upper templates 221, detachable fasteners 3 and bolt accessories in the processing plant according to the required modules; and transport the prefabricated templates and accessories to the construction site, and check and count them to ensure that the materials are complete and undamaged;

[0065] S2: Synchronously set up the templates of the sleeve-shaped outer template assembly 1 and the sleeve-shaped inner template assembly 2. The construction personnel of the sleeve-shaped outer template assembly 1 stand outside the inspection well, connect the first bottom templates 111 in turn with circumferential bolts and fix them to the ground through the anchor 4, and then gradually set up the first upper template 121 upwards to form an outer wellbore; at the same time, the construction personnel of the sleeve-shaped inner template assembly 2 stand inside the inspection well, connect the second bottom templates 211 in turn with circumferential bolts and fix them to the ground through the anchor 4, and then gradually set up the second upper template 221 upwards to form an inner wellbore; the inner and outer templates are installed synchronously to ensure the alignment and sealing of each template;

[0066] S3: Install longitudinal stiffening plates and transverse stiffening plates on each of the first bottom formwork 111, the first upper formwork 121, the second bottom formwork 211, and the second upper formwork 221, respectively, to enhance the rigidity and stability of each formwork;

[0067] S4: Install the detachable fastener 3 on the first upper template 121 and the second upper template 221 at the top, and ensure that the spacing, shape and thickness of the inspection well of the sleeve-shaped outer mold assembly 1 and the sleeve-shaped inner mold assembly 2 meet the design requirements by adjusting the detachable fastener 3;

[0068] S5: After the sleeve-shaped outer formwork assembly 1 and the sleeve-shaped inner formwork assembly 2 are erected to a preset height, concrete pouring and curing are performed;

[0069] S6: After the concrete reaches the design strength, first remove the removable fastener 3; then remove the bolts at the template connection to ensure that the template can be removed smoothly; finally, remove the entire steel template from top to bottom by pulling down the stiffening plate; promptly repair and maintain the removed template. If there is a similar type of inspection well, it can be partially removed, transported, and transferred to the next construction site, and the above steps can be repeated to continue construction.

[0070] Furthermore, in step S2, the digital modeling of the construction plan of the cast-in-place strong and weak current inspection well formwork system is performed using building information modeling (BIM) technology to help engineers better plan the construction process and improve construction efficiency and accuracy. BIM technology can realize the sharing and transmission of construction project information. Each participant can obtain and update the information of the building model at any time to achieve real-time collaboration and communication. Through BIM technology, designers, construction parties, owners and other participants can share the same model to ensure the consistency and accuracy of information. The digital modeling of the construction plan using building information modeling (BIM) technology specifically includes:

[0071] Establishing BIM modeling standards:

[0072] Establish modeling standards: including modeling accuracy, data format, naming rules, etc., to ensure the quality and readability of the model;

[0073] Unified model elements: Model elements should have unified classification, coding and naming rules, and parameterized control should be adopted.

[0074] Creating a BIM Model:

[0075] According to the design drawings of the cast-in-place strong and weak current inspection well template system, a three-dimensional model of the cast-in-place strong and weak current inspection well template system is established, including the geometric information and physical information of the cast-in-place strong and weak current inspection well template system;

[0076] According to the three-dimensional model and structural design drawings of the cast-in-place strong and weak current inspection well formwork system, the structural model of the cast-in-place strong and weak current inspection well formwork system is established, including the geometric dimensions and material information of the structural components;

[0077] Establish construction equipment models according to construction equipment drawings, including equipment geometry information, performance parameters, etc.;

[0078] Model integration and coordination

[0079] Model integration: Integrate BIM models of various disciplines into a unified platform to achieve information sharing and collaborative work;

[0080] Collision check: Use software such as Revit to run collision checks to identify components that conflict between disciplines and within disciplines, and provide design modification opinions and suggestions:

[0081] Model deepening:

[0082] Split composite components: The composite structural components in the design model of the cast-in-place strong and weak current inspection well formwork system should be split according to the construction process;

[0083] Add formwork system: The formwork system of cast-in-place strong and weak current inspection wells should be partially or completely added with formwork system models to realize the classified configuration, statistics and material arrangement of formwork and brackets, as well as the visual explanation of formwork support;

[0084] Checking of reserved holes: By deepening the design model of the cast-in-place strong and weak electricity inspection well template system, the reserved holes of the cast-in-place concrete structural components are checked, and coordinated with the equipment professional pipelines, pipe wells, etc. to ensure accurate reservation and avoid rework in the later stage;

[0085] Complex node modeling: For complex nodes, it is advisable to establish a steel bar solid model for simulation and check the construction feasibility of the node.

[0086] Furthermore, in steps S2-S5, an intelligent monitoring system is introduced to monitor various parameters in the construction process in real time, such as the deformation of the formwork and the pouring of concrete, to ensure the quality of construction. The intelligent monitoring system can transmit the data of the construction site to the monitoring center in real time through sensors and data transmission technology, so that engineering personnel can obtain and analyze the data in a timely manner to ensure construction safety and quality. Computer vision technology is used to monitor the displacement changes of the formwork support structure in real time during the construction process. When unsafe displacement occurs, the system will automatically alarm and guide the elimination of danger to ensure construction safety.

[0087] Furthermore, step S5 includes inspection before pouring: check the stability and sealing of the formwork to ensure that there is no leakage. Check the binding of the steel bars to ensure that the steel bars are accurately positioned and firmly bound; concrete pouring: concrete pouring should be carried out in layers, and the thickness of each layer is generally about 300 mm; pouring should start from one side of the inspection well and gradually move to the other side to ensure uniform concrete pouring; use a vibrating rod to vibrate the concrete to ensure that the concrete is dense and avoid quality problems such as honeycombs and rough surfaces; maintenance: after the concrete is poured, it should be maintained in time. The maintenance method can be watering maintenance or covering with plastic film maintenance. The maintenance time is generally about 7 days to ensure that the concrete reaches the design strength.

[0088] Furthermore, in step S6, the formwork should be handled with care when it is removed to avoid damage to the formwork and concrete structure; the removed formwork should be sorted and cleaned in time, the damage to the formwork should be checked, and necessary repairs and maintenance should be carried out. The sorted formwork can be stored in a designated area for recycling; if there are inspection wells of similar models, they can be partially dismantled, transported, and transferred to the next construction site, and the above steps can be repeated to continue construction.

[0089] The construction method of the present invention refers to the construction drawings to design inner and outer formworks with a certain modulus, align the connecting plates of the steel formworks and connect them with bolts, first set up the (inner and outer) foundation bottom formworks and anchor them firmly with bolts, then set up the upper formworks and fasten the inner or outer formworks piece by piece with bolts, and assemble the inner and outer formworks simultaneously to form an inner wellbore and an outer wellbore. The inner mold wellbore and the outer mold wellbore have a high degree of sealing and can effectively prevent the technical requirements of concrete slurry penetration. Through the connection of steel formwork with a certain modulus, the longitudinal stiffening plate and the transverse stiffening plate are arranged in an orderly manner, so that the inner and outer forms are stabilized, and the shape of the top of the formwork and the thickness of the well are locked by the detachable fastener 3, so that the concrete has a complete adjustable and quick-to-assemble and dismantle formwork support system; the inspection well is formed by concrete pouring and curing; after forming, the detachable fastener 3 is first removed, and then the bolts between adjacent formworks are removed, and the entire steel formwork is removed from top to bottom by pulling down the stiffening plate, and the steel formwork of the modulus can be sorted and recycled sustainably; the flexible steel formwork of the present invention is simple to operate, easy to use, and recyclable, and realizes the effect of quick installation and disassembly, and green environmental protection. Through the above detailed construction method of the present invention, the construction quality of the cast-in-place strong and weak current inspection well can be ensured, the construction efficiency can be improved, and the construction safety can be ensured. In particular, through the use of high consistency inspection and top adjustment fasteners, the height consistency of the formwork assembly can be ensured, thereby ensuring that the size and shape of the inspection well meet the design requirements. At the same time, the flexible assembly and recycling of the formwork realizes the effect of quick installation and disassembly and green environmental protection.
