Description

Technical Field

[0001] This utility model belongs to the field of shield tunnel segment maintenance technology, and in particular relates to an outdoor maintenance device for precast shield tunnel segments. Background Technology

[0002] In construction engineering, precast tunnel segments are an important structural component, and their quality directly affects the safety and stability of the entire project. Concrete, as the main material for precast tunnel segments, requires particularly careful curing. Proper curing time and methods can significantly improve the strength and durability of concrete, ensuring that the precast tunnel segments meet design requirements.

[0003] Precast tunnel segments are mostly cured using water curing. There are three main methods: 1) Manual water spraying, where workers carry water hoses to spray water onto the segment surface. This method is suitable for small-scale segment production where segments are relatively concentrated. 2) Water curing, where mobile carts transport segments to curing platforms for water curing, allowing for water recycling. However, the frequency of water recycling is low, and multiple curing platforms are needed for large-scale production, which is uneconomical and requires significant labor. 3) Water truck spraying, suitable for large-scale segment production, but requires vehicle access in the segment storage area, wasting limited resources and resulting in high construction costs.

By setting multiple of these curing devices on the precast segments, the water spraying curing range can cover the entire surface of the precast segments without the need for additional channels, thus avoiding resource waste and reducing construction costs. By using fixed brackets to install these curing devices on the precast segments, comprehensive water spraying curing of precast segments in the storage area can be achieved without consuming too much manpower, thereby effectively utilizing the segment storage space and maximizing resource utilization.

[0008] The fixing frame includes two fixing rods symmetrically arranged at the bottom of the mounting base and a bracket fastener horizontally inserted between the two fixing rods; a support pad is provided at the connection between the fixing rod and the precast segment.

[0009] The above-mentioned outdoor curing device for precast tunnel segments is characterized in that: the water supply pipe and the soft water pipe are connected by a connecting component, the connecting component including a receiving plug installed at the end of the water supply pipe and a connecting end provided on the soft water pipe for connecting with the receiving plug.

[0010] The above-mentioned outdoor curing device for precast tunnel segments is characterized in that: the rotating nozzle is connected to the water supply pipe through a water supply branch pipe.

[0021] like Figure 1 and Figure 2 As shown, this utility model includes a water supply pipe 2 installed on the precast pipe segment 1, a fixed bracket installed below the water supply pipe 2 and connected to the precast pipe segment 1, and a plurality of rotating nozzles 3 installed above the water supply pipe 2 for spraying water to maintain the precast pipe segment 1.

[0022] The end of the water supply pipe 2 is connected to a soft water pipe 4;

[0023] The fixing bracket includes two fixing units symmetrically arranged below the water supply pipe 2. The two fixing units have the same structural dimensions. Each fixing unit includes a mounting base 7 arranged below the water supply pipe 2 and a fixing frame arranged at the bottom of the mounting base 7. The mounting base 7 and the water supply pipe 2 are fixedly connected, and the mounting base 7 and the fixing frame are connected by a butt thread 9.

[0024] The fixing frame includes two fixing rods 8 symmetrically arranged at the bottom of the mounting base 7 and a bracket fastener 10 horizontally inserted between the two fixing rods 8; a support pad 11 is provided at the connection between the fixing rods 8 and the precast segment 1.

[0025] In practical use, by setting multiple of these curing devices on the precast segment 1, the water spraying curing range can cover the entire surface of the precast segment 1 without the need for additional channels, thus avoiding resource waste and reducing construction costs. By using fixed brackets to install these curing devices on the precast segment 1, the precast segment 1 in the storage area can be fully watered for curing without consuming too much manpower, thereby effectively utilizing the segment storage area and maximizing resource utilization.

[0026] It should be noted that the bracket fastener 10 can be used to secure the fixing frame when the precast segment 1 is placed on its side and there are no pre-embedded holes, or to freely fix it at different angles on the precast segment 1. Water is supplied to the rotating nozzle 3 through the water supply pipe 2, and connected to an external water source through the soft water pipe 4.

[0027] In particular, the rotating nozzle 3 uses water as its power source. The water jet, impacted and sprayed out, falls evenly in an umbrella shape. The water jet from the upper part has a certain angle of inclination. During spraying, the rotating blade causes the water jet to move in a circular motion, effectively covering the corners and bends formed by the high density of the pipe segments, creating an effect similar to natural rainfall. No personnel supervision is required during the process, saving construction costs and providing good maintenance. The water used for spraying can be recycled and reused using the drainage system of the pipe segment storage area.

[0028] like Figure 1 As shown, in this embodiment, the water supply pipe 2 and the soft water pipe 4 are connected by a connecting component. The connecting component includes a receiving plug 5 installed at the end of the water supply pipe 2 and a connecting end 6 disposed on the soft water pipe 4 for connecting to the receiving plug 5.

[0029] In actual use, if the end of the water supply pipe 2 does not need to be installed with the soft water pipe 4, the end of the water supply pipe 2 can be sealed with a sealing cap.

[0030] like Figure 1 As shown, in this embodiment, the rotating nozzle 3 is connected to the water supply pipe 2 via the water supply branch pipe 12.

[0031] In actual use, a rotating nozzle 3 is set up to spray maintenance water; water is supplied to the rotating nozzle 3 through the water supply branch pipe 12.

[0032] like Figure 1 As shown, in this embodiment, the mounting base 7 has a figure-eight structure, and the mating thread 9 is installed at the connection between the fixing rod 8 and the mounting base 7; the fixing rod 8 has an L-shaped structure, the bracket fastener 10 is arranged on the vertical section of the fixing rod 8, and the support pad 11 is arranged on the horizontal section of the fixing rod 8.

[0033] In actual use, the mounting base 7 and the fixing frame can be freely disassembled and installed through the connecting thread 9. The support 11 contacts the precast segment 1, which serves two purposes: firstly, to ensure a firm contact between the fixing rod 8 and the precast segment 1; and secondly, to prevent damage to the precast segment 1.

[0034] In use, this utility model connects the curing devices in series using flexible water pipes 4, based on the watering area of ​​the precast pipe segment 1. The watering range can fully cover the precast pipe segment 1. The curing devices are fixed to the precast pipe segment 1 in a matrix arrangement. The installation distance of the curing devices is determined according to the watering effect, and the outermost end is sealed with a sealing cap. After the water supply pump is turned on, water flows through the flexible water pipes 4 to provide power to the curing devices. The water spraying effect of the curing devices is an umbrella-shaped circular motion, realizing an automatic spraying effect. Observe the water spraying of the automatic nozzles and adjust the spacing and position of the automatic nozzles as appropriate to ensure uniform water spraying and no missed spraying on the surface of the precast pipe segment 1.

[0035] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
