Description

Technical Field

[0001] This utility model relates to a waterproof cable tray anti-damage decoration structure, belonging to the technical field of waterproof cable tray construction for subway transportation. Background Technology

[0002] Water leakage in waterproof cable trays is a common problem in urban rail transit automatic fare collection systems. Once water enters the cable trays, not only is drainage difficult, but it also poses a significant safety hazard to urban rail transit operations. There are many reasons for cable tray leakage. Besides insufficient waterproofing performance of the cable trays themselves and improper installation, the most significant cause is damage to the cable trays after installation. Currently, the construction method for subway station concourse decoration involves first installing waterproof cable trays, then conducting an airtightness test, followed by pouring the foundation layer, and finally laying the concourse stone cladding. This construction method often results in the cable trays being damaged by machinery during the foundation layer pouring and stone cladding laying processes, rendering the airtightness test ineffective and ultimately leading to water leakage. Furthermore, replacing damaged cable trays is very costly and also delays the construction period. Utility Model Content

[0003] Based on the above, this utility model provides a waterproof cable trough anti-damage decoration structure to overcome the shortcomings of the prior art.

[0004] The technical solution of this utility model is: a waterproof cable tray anti-damage decoration structure, comprising:

[0005] Reinforced concrete floor slabs;

[0006] Waterproof cable trays are installed on the reinforced concrete floor slab;

[0007] A concrete cushion layer is provided on the reinforced concrete floor slab and located on both sides of the waterproof groove;

[0008] The first dry-hardened mortar layer is laid on the concrete subbase;

[0009] The second dry-hardened mortar layer is laid on the waterproof groove;

[0010] The first stone layer is laid on the first dry hard mortar layer;

[0011] The second stone layer is laid on the second dry hard mortar layer, wherein the two sides of the second stone layer are aligned with the sides of the first stone layer.

[0012] In one example, the waterproof cable channel is installed on the reinforced concrete floor slab using cable channel fixing clips.

[0013] In one example, the gap between the reinforced concrete floor slab and the waterproof groove is filled with a cement mortar sealant.

[0014] In one example, the first dry-hardened mortar layer is laid on the top outer side of the concrete subbase, and the second dry-hardened mortar layer is laid on the top inner side of the concrete subbase and on the waterproof groove and cement mortar filler layer.

[0015] In one example, the back of the first stone layer is coated with a first cement slurry bonding layer.

[0016] In one example, a second cement slurry bonding layer is applied to the back of the second stone layer.

[0017] The beneficial effects of this utility model are:

[0018] 1. By setting up a separate concrete pad layer, a first dry-hardened mortar layer, and a first stone layer, the base construction on both sides is completed before the waterproof cable trench is installed, forming a protective construction channel and preventing subsequent construction equipment from directly crushing the cable trench area. This solves the technical problem of cable trench damage from a structural layout perspective.

[0019] 2. Through the synergistic fixing effect of the cable tray fixing clips and the cement mortar filling layer, a stable connection is formed between the waterproof cable tray and the reinforced concrete floor slab. At the same time, the combined structure of the second dry-hardened mortar layer and the second cement grout bonding layer not only ensures the flatness of the stone paving, but also provides a flexible protective layer for the cable tray.

[0020] 3. By aligning the first and second stone layers, a structural system that allows for zoned maintenance is formed while ensuring a unified decorative effect. When maintenance is required, the second stone layer can be disassembled and installed in a targeted manner, significantly reducing the later maintenance costs. Attached Figure Description

Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0026] Please see Figure 1 and Figure 2 This embodiment discloses a waterproof cable trench anti-damage decoration structure, comprising a reinforced concrete floor slab 1, a waterproof cable trench 10, a concrete pad layer 2, a first dry-hardened mortar layer 3, a second dry-hardened mortar layer 6, a first stone layer 4, and a second stone layer 5. The waterproof cable trench 10 is installed on the reinforced concrete floor slab 1 using cable trench fixing clips 8. Concrete pad layers 2 are provided on both sides of the reinforced concrete floor slab 1 and the waterproof cable trench 10. A cement mortar grouting layer 9 is used to fill the gap between the reinforced concrete floor slab 1 and the waterproof cable trench 10. The first dry-hardened mortar layer 3 is laid on the concrete pad layer 2, and the second dry-hardened mortar layer 6 is laid on the waterproof cable trench 10. A cement slurry bonding layer is evenly applied to the back of the first stone layer 4 and laid on the first dry-hardened mortar layer 3. Similarly, a cement slurry bonding layer is evenly applied to the back of the second stone layer 5 and laid on the second dry-hardened mortar layer 6. The sides of the second stone layer 5 are aligned with the edges of the first stone layer 4.

[0027] It should be noted that the first dry-hard mortar layer 3 is laid on the top outer side of the concrete pad 2, and the second dry-hard mortar layer 6 is laid on the top inner side of the concrete pad 2 and on the waterproof groove 10 and the cement mortar filling layer 9, so as to avoid the first dry-hard mortar layer 3 falling off and affecting the installation of the waterproof groove 10.

[0028] The construction method for the above-mentioned waterproof cable trench to prevent damage to the decorative structure is as follows:

[0029] S1: Based on the location diagram of the cable trench after the refinement, locate it on site and use a chalk line to mark the line on the reinforced concrete floor slab 1, leaving a 700mm wide channel. The center line of the channel should coincide with the center line of the cable trench in the drawing, and spray the words "AFC cable trench, do not cover" along the direction of the channel.

[0030] S2: Before pouring the foundation layer, use 50*100mm timber to support the formwork according to the marked lines on the ground. The formwork should be erected to prevent grout leakage. After the formwork is erected, pour the concrete foundation layer 2 to a height of 100mm, and ensure it is vibrated to compact it.

[0031] S3: First, lay a 1:3 first dry-hard mortar layer 3 on the concrete base layer 2. The first dry-hard mortar layer 3 should be laid flat and 10mm higher than the design elevation. Then, evenly apply the first cement slurry bonding layer 11 to the back of the first stone layer 4 and place it on the first dry-hard mortar layer 3. Apply even pressure to ensure that the first dry-hard mortar layer 3 and the first cement slurry bonding layer 11 are tightly bonded, and the surface of the first stone layer 4 is flat.

[0032] S4: Follow the steps in S3 until the large-area stone paving is completed. After determining the location of the grooves according to the drawings, use a chalk line to mark the lines on the reinforced concrete floor slab 1.

[0033] S5: Install the waterproof groove 10 according to the marked position. During the installation process, keep the groove straight, the connection position secure, and the height difference between the two sides of each section of the groove should not exceed 5mm.

[0034] S6: Find an inspection port on the installed waterproof cable tray 10, replace it with a special cover plate for air tightness testing, and use an air pump to pump air into the waterproof cable tray 10 until the air pressure inside the waterproof cable tray 10 reaches 10KP. After 30 minutes, if the air pressure drops to within 5%, it is considered qualified.

[0035] S7: After passing the airtightness test, use the cable tray fixing clips 8 to fix the waterproof cable tray 10 to the reinforced concrete floor slab 1. When the cable tray length is between 1500-2500mm, install one cable tray fixing clip 8 at each end of the waterproof cable tray 10 at a position of 300mm-600mm. Adjustments can be made as needed if there is a cable outlet. When the cable tray length is less than 1500mm, one cable tray fixing clip 8 can be placed in the center. The cable tray fixing clip 8 can be fixed to the floor slab with expansion bolts 7.

[0036] S8: Lay a 1:2.5 flowable cement mortar on the concrete cushion layer 2, filling the gap between the waterproof groove 10 and the reinforced concrete floor slab 1 as much as possible to form a mortar filling layer.

[0037] S9: First, lay a 1:3 second dry-hard mortar layer 6 on the concrete base layer 2 and the mortar joint filling layer. The second dry-hard mortar layer 6 should be laid flat and 10mm higher than the design elevation. Then, evenly apply the second cement slurry bonding layer 12 to the back of the second stone layer 5 and place it on the second dry-hard mortar layer 6. Apply even pressure to ensure that the second dry-hard mortar layer 6 and the second cement slurry bonding layer 12 are tightly bonded, and the surface of the second stone layer 5 is flat.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
