Description

Technical Field

[0001] This application relates to the field of building construction, specifically to a construction structure for an integrally cast drainage ditch using an inflatable model and bamboo tubes in tropical regions. Background Technology

[0002] In tropical regions, the construction of traditional brick-built drainage ditches is costly, requiring large quantities of bricks, cement, and other materials, and the construction process is cumbersome and time-consuming. Installing rainwater grates not only increases costs but also poses risks of damage and theft, resulting in high maintenance costs. To address these issues, the development of a new type of combined drainage ditch device is urgently needed. Utility Model Content

[0003] The purpose of this invention is to provide a construction structure for an integrally cast drainage ditch using an inflatable model and bamboo tube in tropical regions, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A construction structure for a drainage ditch made of inflatable model and bamboo tubes in tropical regions is mainly set up near the foundation pit and enclosure for temporary drainage on the construction site. It includes the original soil and fine sand base. The structure is characterized by: a trench opened on the original soil and fine sand base, an inflatable model placed in the trench, hardened concrete on the ground, and bamboo tubes inserted into the hardened concrete and above the inflatable model.

[0005] More preferably, the bottom of the bamboo tube is sealed with tape or food wrap.

[0006] Furthermore, the air mold is provided along the entire length of the groove.

[0007] Furthermore, the inflatable model is formed by connecting several inflatable units end to end, and adjacent inflatable units are connected by wrapping them with food preservation film.

[0008] Furthermore, six or eight bamboo tubes are inserted above each individual air-formed unit and into the hardened concrete ground.

[0009] Furthermore, the width of the groove is greater than the width of the inflatable model, and the height of the inflatable model is greater than the depth of the groove.

[0010] Furthermore, both the original soil and fine sand base and the bottom of the trench are provided with a concrete cushion layer.

[0011] In addition, the upper part of the air model unit has an arc-shaped structure.

[0012] More preferably, the ground hardening concrete is poured on the original soil and fine sand base and in the trench to form a ground hardening structure, and the bamboo tube has a diameter of 4~5cm.

[0013] Compared with the prior art, this utility model has the following features and beneficial effects: Cost advantages: Eliminating the need for brickwork and rain grate installation reduces the procurement costs of materials such as bricks, cement, and rain grate installation. At the same time, it simplifies the construction process, reduces labor costs, and significantly reduces construction costs.

[0014] Convenient construction: Compared with the complex construction process of traditional brick drainage ditches, this device only requires the installation of air molds and bamboo tubes before pouring concrete. The construction process is simple and the construction period is short, which can effectively speed up the project progress.

[0015] Structural stability: The integrally cast concrete structure has higher strength than brick masonry structures. The tropical fine sand foundation is relatively more stable, and the structure has stronger resistance to settlement and deformation, resulting in a longer service life for the drainage ditch.

[0018] To make the technical means, innovative features, objectives and effects of this utility model easier to understand, the utility model will be further described below.

[0019] The embodiments described herein are specific implementations of this utility model, used to illustrate the concept of this utility model. They are all illustrative and exemplary, and should not be construed as limiting the implementation methods or scope of this utility model. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.

[0020] Example 1 A construction structure for a tropical drainage ditch using an inflatable model and bamboo tubes, integrally cast in place, such as... Figure 1 and 2As shown, this system is mainly used for temporary drainage near the foundation pit and perimeter fencing. It includes the original soil and fine sand base 1, a trench 2 dug on the original soil and fine sand base 1, an inflatable structure 3 placed in the trench 2, hardened concrete 4, and bamboo tubes 5 inserted into the hardened concrete 4 and above the inflatable structure 3. The bamboo tubes 5 form inlets in the hardened concrete, and their bottoms are sealed with tape or food wrap. The concrete in the drainage ditch is poured together with the hardened concrete, ensuring even coverage of the inflatable structure and bamboo tubes. After the concrete reaches its design strength, the inflatable structure is deflated and removed. Then, a sharpened wooden stick is used to poke open the tape or food wrap at the bottom of the bamboo tube, making the inside of the bamboo tube interconnected, forming an integrated drainage ditch. The inflatable structure 3 is a continuous structure extending along the trench, made of high-strength, wear-resistant rubber or plastic, with good flexibility and deformation resistance. It serves to reserve drainage space during concrete pouring and can be reused repeatedly.

[0021] Example 2 Based on Example 1, the air model 3 is formed by connecting several air model units end to end. Adjacent air model units are connected by wrapping them with food preservation film. The preservation film is relatively soft and does not affect the air model's retraction after deflation. It also plays a certain role in supporting the concrete and positioning the air model. The drainage ditch needs to be constructed in sections according to the length of the air model units.

[0022] Six or eight bamboo tubes 5 are inserted into the hardened concrete 4 above each air-formed unit. The number of bamboo tubes can be set at intervals as needed, and can be set according to the length and width of each air-formed unit to form a structure similar to a drainage grate. The width of the trench 2 is greater than the width of the air-formed unit 3, and the height of the air-formed unit 3 is greater than the depth of the trench 2. The concrete on both sides of the air-formed unit and in the trench can support the air-formed unit and form a drainage channel.

[0023] Both the original soil and fine sand base 1 and the bottom of the trench 2 are equipped with concrete cushion layers. After the original soil and fine sand base is compacted to form a stable foundation, the concrete cushion layer is no longer required. The upper part of the air model unit is an arc-shaped structure, which can increase the load-bearing capacity of the upper part of the air model. The ground hardening concrete 4 is poured on the original soil and fine sand base 1 and inside the trench 2 to form a ground hardening structure. The bamboo tube 5 has a diameter of 4~5cm. After the ground hardening concrete 4 is poured and cured, the ground and drainage ditch are constructed and formed.

[0024] Tropical regions have many sandy soil layers. After excavation, the sand is generally fine and relatively dense. Therefore, a concrete subbase is not needed before constructing drainage ditches. In other regions, a concrete subbase is required.

[0025] The core components involved in this application are as follows: Finished strip air mold: Made of high-strength, wear-resistant rubber or plastic material, it has good flexibility and resistance to deformation. It plays a role in reserving drainage space during concrete pouring and can be reused repeatedly.

[0026] 4cm diameter bamboo tube: Select bamboo with hard texture and uniform wall thickness, seal the bottom with tape, and insert it during concrete construction to serve as a channel for water inlet, drainage or ventilation.

[0027] The workflow involved in this application is as follows: Preliminary preparations: Level the site in the drainage ditch construction area, clear away fine sand and debris, and compact the original soil and fine sand base to ensure foundation stability.

[0028] Installation of inflatable models and bamboo tubes: Before the drainage ditch is hardened, place the prefabricated strip inflatable models in the designated positions. When pouring concrete, insert 4cm diameter bamboo tubes with the bottom sealed with tape according to the designed spacing; Concrete pouring: The drainage ditch concrete is poured together with the hardened ground concrete to ensure that the concrete is evenly covered by the air mold and bamboo tubes, and is vibrated to ensure the strength and integrity of the concrete.

[0029] Molding process: After the concrete reaches the design strength, deflate the inflatable mold and remove it. Then, use a sharpened wooden stick to poke open the tape at the bottom of the bamboo tube, making the inside of the bamboo tube open and forming an integral drainage ditch.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered illustrative and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
