Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of construction auxiliary facilities for building engineering, specifically a prefabricated temporary drainage integrated pipe trench suitable for construction sites. Background Technology
[0002] In construction sites, especially in scenarios involving foundation pit projects, foundation pits are usually located below the ground surface and are prone to accumulating rainwater or groundwater. If the water is not drained in time, the water accumulation in the foundation pit may reduce the bearing capacity of the foundation and induce safety accidents such as foundation pit collapse.
[0003] Drainage channels, by effectively collecting and discharging surface water and accumulated water around the foundation pit, can maintain the dryness and stability of the pit environment and are an important facility for ensuring construction safety. However, existing drainage ditches generally adopt the method of temporary excavation or laying of simple channels on site, which has the following main disadvantages:
[0004] 1. On-site construction of drainage ditches requires a lot of materials and manpower. At the same time, the temporary design of the ditches results in poor reusability and low resource utilization.
[0005] 2. Simple ditches are prone to leakage or blockage during drainage, which cannot effectively collect surface water and may even cause water accumulation around the foundation pit, affecting the construction progress.
[0006] 3. Existing drainage ditches typically discharge surface water directly, failing to make rational use of water resources and thus failing to meet the environmental protection requirements of green construction.
[0007] On the other hand, integrated cabling (such as electrical cables and communication cables) at construction sites is a crucial facility for ensuring the operation of construction equipment and information transmission. However, the current methods of arranging integrated cabling have the following drawbacks:
[0008] 1. Due to the variety of cables and temporary water pipes at the construction site and their different installation methods, there are often problems of tangling and random laying. This not only affects the cleanliness of the construction site, but also increases the complexity of construction management.
[0009] 2. Improper cable layout may lead to cable damage or even short circuits, threatening the safety of construction personnel and equipment.
[0010] 3. Due to the disorderly cable layout, it is difficult to quickly locate and repair faults, affecting the normal operation of construction.
[0011] Drainage ditches and integrated cabling often need to be laid out in the same construction area, but the existing decentralized layout further exacerbates the complexity of the construction site. The cross-interference between drainage ditches and cables may lead to difficulties in construction deployment, prolong the construction period, and increase construction costs. Utility Model Content
[0012] The main purpose of this utility model is to provide a prefabricated temporary drainage integrated pipe trench suitable for construction sites, which optimizes drainage and pipeline layout at construction sites and improves construction efficiency.
[0013] The prefabricated temporary drainage integrated pipe trench provided by this utility model is composed of multiple identical prefabricated pipe trenches spliced together. Each prefabricated pipe trench includes a prefabricated trench body, a partition plate, a pipe layer, and a filter layer. The partition plate is a permeable plate, which is set in the prefabricated trench body to divide the prefabricated trench body into an upper part and a lower part. The upper part is provided with a pipe layer and a filter layer, and the lower part is a drainage area.
[0014] In one embodiment of the aforementioned trench, the prefabricated trench body is rectangular in shape, integrally prefabricated, and made of high-strength concrete.
[0015] In one embodiment of the aforementioned trench, tongue and groove structures are provided at both ends of the prefabricated trench body, and each section of prefabricated pipe is connected and spliced through the tongue and groove joints.
[0016] In one embodiment of the above-mentioned trench, the partition plate is prefabricated as a whole using concrete material and is integrally formed with the prefabricated trench body; multiple drainage holes are evenly opened on the partition plate.
[0017] In one embodiment of the aforementioned pipe trench, the pipe layer includes fire-fighting pipes, temporary electrical conduits, and water supply pipes arranged in parallel; each pipe is fixed to the central partition using a fixed bracket.
[0018] In one embodiment of the above-mentioned trench, the filter layer is disposed above the pipe layer, and the filter layer includes a graded crushed stone layer, a medium-coarse sand layer and a geotextile layer arranged sequentially from top to bottom.
[0019] In one embodiment of the aforementioned trench, the geotextile is adhered to the upper surface of each pipe and the upper surface of the partition plate.
[0020] In one embodiment of the aforementioned trench, lifting holes are respectively opened at the four corners of the top of the prefabricated trench.
[0021] The beneficial effects of this utility model are as follows:
[0022] 1. All types of pipes and cables are uniformly arranged in the integrated pipe trench, avoiding the complex layout of pipelines and drainage on traditional construction sites and reducing construction interference;
[0023] 2. The integrated utility tunnel adopts a prefabricated assembly design, which has good turnover and can be reused, significantly reducing the waste of disposable materials. At the same time, after prefabrication, only hoisting and splicing are required on the construction site, eliminating the need for cumbersome on-site processing, reducing material loss and labor input during construction, and improving construction efficiency.
[0024] 3. Tongue and groove connections are used between each section of the integrated pipe trench to ensure the stability and sealing performance of the connection between the pipe trenches, which helps to prevent leakage during long-term use and improve drainage and protection performance.

[0028] The relevant technical solutions will now be clearly and completely described with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0029] like Figure 1 As shown in the figure, the prefabricated temporary drainage integrated pipe trench disclosed in this embodiment, which is suitable for construction sites, is composed of multiple identical prefabricated pipe trenches spliced together.
[0030] A single-section precast pipe trench includes a precast trench body 1, a partition plate 2, a pipe layer 3, a filter layer 4, and a hoisting hole 5.
[0031] The precast trench 1 is rectangular in shape and is precast as a single unit. It is made of high-strength concrete to ensure that the trench has sufficient strength and durability.
[0032] like Figure 2 As shown, tongue and groove joints 11 are provided at both ends of the prefabricated trench 1. Each section of prefabricated pipe is connected and spliced through the tongue and groove joints, which are firmly connected and have good sealing performance, effectively preventing water leakage and seepage.
[0033] The partition 2 is installed inside the prefabricated trench 1, dividing the trench into an upper and lower section. The upper part of the partition is the pipe layer 3, and the lower part is the drainage area, which allows for the independent arrangement of drainage and cable pipes.
[0034] The drainage area is used to collect purified water from the laminar flow of the filter. The water flows out of the drainage area and connects to the sedimentation tank or other treatment devices at the construction site to achieve efficient recycling of water resources.
[0035] like Figure 3As shown, the partition 2 is prefabricated from concrete and integrally formed with the trench body. Multiple drainage holes are evenly distributed on the partition to drain the filtered water from the upper filter layer 4 to the lower drainage area, achieving efficient drainage and reducing water accumulation.
[0036] Pipe layer 3 includes fire-fighting pipes 31, temporary electrical conduits 32, and water supply pipes 33 arranged in parallel. Each pipe is fixed to the central partition 2 with a fixed bracket to ensure safe and reliable operation of the pipeline.
[0037] The filter layer 4 is located above the pipe layer and is used to filter and purify surface water to ensure that the water entering the lower drainage area meets the requirements for reuse. The filter layer includes a graded crushed stone layer 41, a medium-coarse sand layer 42, and a geotextile 43 arranged sequentially from top to bottom.
[0038] The bottom layer of geotextile 43 is attached to the upper surface of each pipe and the upper surface of the partition plate.
[0039] Setting up geotextiles can prevent the loss of graded crushed stone and medium-coarse sand in the upper layer, maintain the overall structure and function of the filter layer, and enhance the tensile strength and deformation resistance of the filter layer; at the same time, it can effectively diffuse, transfer or decompose concentrated stress, and protect each pipe and partition from wear.
[0040] The top four corners of the precast trench 1 are each provided with a hoisting hole 5, which facilitates the rapid movement and installation of the trench using hoisting equipment during construction, greatly improving construction efficiency.
[0041] A method for installing and using this integrated pipe trench on a construction site, comprising the following steps:
[0042] 1. Foundation treatment: Excavate foundation trenches at the installation location, ensuring that the width, depth and flatness of the trenches meet the installation requirements of precast pipe trenches; compact the foundation trenches to ensure the foundation is stable.
[0043] 2. Precast trench hoisting: Use hoisting equipment to hoist the precast trench section by section into the foundation trench; during the hoisting process, take care to protect all components of the precast trench to avoid collisions and damage.
[0044] 3. Pipe trench splicing: Splice the precast pipe sections together using a tongue and groove structure to ensure a firm connection and good sealing performance; check the flatness and tightness of the splice, and make adjustments and reinforcements if necessary.
[0045] 4. Pipe and cable layout: Fire protection pipes, temporary power supply conduits and water supply pipes are laid in the pipe layer according to the design requirements; fixed supports are used to firmly fix each pipe to the partition plate; according to the cable layout requirements of the construction site, integrated cables are reasonably laid in the pipe trench.
[0046] 5. Filter layer laying: A graded crushed stone layer, a medium-coarse sand layer and a geotextile are laid in sequence above the pipe layer to form a filter layer; ensure that the geotextile adheres to the upper surface of each pipe and the upper surface of the partition plate to prevent the upper material from being lost.
[0047] The advantages of using this integrated utility trench are:
[0048] 1. All types of pipes and cables are uniformly arranged in the integrated pipe trench, avoiding the complex layout of pipelines and drainage on traditional construction sites and reducing construction interference.
[0049] 2. The integrated utility tunnel adopts a prefabricated assembly design, which has good turnover and can be reused, significantly reducing the waste of disposable materials. At the same time, after prefabrication, only hoisting and splicing are required on the construction site, eliminating the need for cumbersome on-site processing, reducing material loss and labor input during construction, and improving construction efficiency.
[0050] 3. Tongue and groove connections are used between each section of the integrated pipe trench to ensure the stability and sealing performance of the connection between the pipe trenches, which helps to prevent leakage during long-term use and improve drainage and protection performance.
[0051] 4. By combining the pipe trench with the construction site's environmental protection equipment, the surface water is collected and purified through the filter layer, and the filtered water is used for construction and production, which not only solves the drainage problem, but also realizes the recycling of water resources.
[0052] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although detailed descriptions have been provided with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
