Description

Technical Field

[0001] This invention relates to an integrated molding and rapid construction method for prefabricated cable trenches in energy storage power stations, belonging to the field of energy storage power station construction technology. Background Technology

[0002] The cables for energy storage power stations need to be laid through cable trenches. Existing technology (see Chinese Patent Announcement No. CN110808564B) uses on-site casting process. Although it can make cable trenches, the on-site casting process is inefficient and cannot meet the requirements of rapid construction. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides an integrated molding and rapid construction method for prefabricated cable trenches in energy storage power stations.

[0004] The present invention is achieved through the following technical solutions.

[0005] This invention provides an integrated molding and rapid construction method for prefabricated cable trenches in energy storage power stations, comprising: The construction process involves multiple prefabricated cables being assembled and interlocked with each other after prefabrication.

[0006] The construction process includes rapid hoisting and interlocking connection steps. The precast cable trench is hoisted onto the pad layer by binding rope with threaded sleeves. Multiple precast cable trenches are assembled, with the front end of the previous precast cable trench section spliced ​​with the rear end of the next precast cable trench section. At this time, the male insert block B and female groove B at the rear end of the precast cable trench are interlocked with the corresponding insert block A and female groove A at the front end of the precast cable trench.

[0007] The male insert B at the rear end of the precast cable trench is diagonally offset from the insert A at the front end of the precast cable trench, so that the female groove B and the female groove A are also diagonally offset.

[0008] The construction process also includes two steps: the initial design and fabrication of standardized molds, and the integrated molding of prefabricated cable trench segments.

[0009] The standardized mold design and manufacturing steps are as follows: the mold for the precast cable trench consists of an inner mold body, an outer mold body, a front mold body, and a rear mold body; the front mold body is provided with a protrusion A and a recess A for forming the male insert A and female groove A at the front end of the precast cable trench; the rear mold body is provided with a protrusion B and a recess B for forming the male insert B and female groove B at the rear end of the precast cable trench.

[0010] The integrated molding steps of the prefabricated cable trench segment are as follows: the mold is laid and installed, the mold is detachably connected and assembled with components such as bolts and nuts, threaded sleeves are pre-embedded between the inner mold body and the outer mold body, concrete is poured into the mold and vibrated and then placed to solidify.

[0011] The construction process also includes a subsequent rapid installation step of the cable bracket, which involves fixing the cable bracket to the threaded sleeve embedded in the side of the precast cable trench using bracket bolts, and then laying the cable on the inner wall of the precast cable trench with support through the cable bracket.

[0012] The beneficial effects of this invention are as follows: since multiple prefabricated cable trenches are prefabricated and then interlocked with each other through male insert B and female groove B and insert A and female groove A, the problem of low efficiency in on-site casting process for making cable trenches and inability to meet the requirements of rapid construction is solved.

Detailed Implementation

[0014] The technical solution of the present invention is further described below, but the scope of protection is not limited to what is described.

[0015] like Figures 1 to 3 As shown.

[0016] This application discloses an integrated molding and rapid construction method for prefabricated cable trenches in energy storage power stations, comprising the following steps.

[0017] Step 1, Standardized mold design and manufacturing: The mold 1 for the prefabricated cable trench consists of an inner mold body 11, an outer mold body 12, a front mold body 13, and a rear mold body 14; the front mold body 13 is provided with a protrusion A131 and a recess A132 for forming the male insert A and female groove A at the front end of the prefabricated cable trench 2; the rear mold body 14 is provided with a protrusion B141 and a recess B142 for forming the male insert B21 and female groove B22 at the rear end of the prefabricated cable trench 2.

[0018] Step 2, integrated molding of precast cable trench segments: After the mold 1 is laid and installed, the mold 1 is detachably connected and assembled with components such as bolts and nuts. Threaded sleeves 3 are pre-embedded between the inner mold body 11 and the outer mold body 12. C40 concrete is poured into the mold 1 and vibrated before being placed to solidify, so that the precast cable trench 2 segments are solidified and formed in the mold 1. After curing to a design strength of more than 75%, the mold is removed, and the precast cable trench 2 is precast. Steps 1 and 2 are repeated to obtain multiple precast cable trench 2 segments.

[0019] Step 3, on-site foundation preparation: excavate the foundation trench according to the design drawings at the construction site and pour the foundation layer.

[0020] Step 4, rapid hoisting and interlocking connection: Using threaded sleeves 3 and ropes, the prefabricated cable trench 2 is hoisted onto the padding layer. Multiple prefabricated cable trenches 2 are assembled, with the front end of the previous section of prefabricated cable trench 2 connected to the rear end of the next section. At this time, the male insert block B21 and female groove B22 at the rear end of the prefabricated cable trench 2 are interlocked with the corresponding insert block A and female groove A at the front end of the prefabricated cable trench 2. Step 4 is repeated to assemble multiple prefabricated cable trenches 2. The male insert block B21 at the rear end of the prefabricated cable trench 2 is diagonally staggered with the insert block A at the front end of the prefabricated cable trench 2, and the female groove B22 is also diagonally staggered with the female groove A.

[0021] Since multiple prefabricated cable trenches 2 are prefabricated and then interlocked with each other through male insert B21 and female groove B22, the problem of low efficiency in on-site casting of cable trenches and inability to meet the requirements of rapid construction is solved.

[0022] Step 5, quick installation of cable brackets: The cable bracket 4 is fixed to the threaded sleeve 3 embedded on the side of the prefabricated cable trench 2 by the bracket bolt 41. The cable is supported by the cable bracket 4 and laid on the inner wall of the prefabricated cable trench 2.

[0023] Step 6, Cover plate installation and backfilling: Install the cover plate on the top of the prefabricated cable trench 2 (this is existing technology and will not be described in detail), and then backfill soil is compacted to bury the prefabricated cable trench 2 with the laid cables underground.
