Description

Technical Field

[0001] The present invention relates to the technical field of pipeline protection in building construction, and in particular to a cable-type communication pipeline protection structure and a construction method thereof. Background Art

[0002] During foundation pit construction, in order to avoid the impact of construction on pipelines within the scope of foundation pit excavation, it is often necessary to carry out in-situ protection of some pipelines in the foundation pit. Communication pipelines are a common underground pipeline with a relatively light weight. During foundation pit construction, in order to avoid large deformation of communication pipelines and thus affect their use functions, it is necessary to control the vertical displacement of the pipeline mid-span within a certain range when formulating and implementing the in-situ protection plan to ensure the normal working state of the communication pipeline.

[0003] For example, the Chinese utility model patent with publication number CN215928602U discloses a suspension protection device for underground pipelines in open excavation pits. Through a double-slot structure and a suspension rod, underground rainwater, sewage, power and communication pipelines can be suspended for protection. It is easy to install and can be reused. However, this solution has the following shortcomings: the suspension protection structure has many design components, occupies a large space, is inconvenient to transport, has low flexibility in use, and the pipeline is directly hoisted through a pallet. It is difficult to adjust the pipeline after it sags and deforms, and it is easy to cause damage at the bend. Summary of the invention

[0004] The present invention aims to solve the deficiencies of the prior art and provides a cable-type communication pipeline protection structure and a construction method thereof.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a cable-type communication pipeline protection structure, including a pier assembly, a cable assembly, and a nylon sling; the pier assemblies are correspondingly arranged on the top of both sides of the foundation pit, the cable assembly is connected between the pier assemblies, and a plurality of nylon slings are hung on the cable assembly, and the communication pipeline is hoisted by the nylon sling.

[0006] In particular, the pier assembly includes a concrete pier, an embedded steel plate, and a steel ear plate. The concrete pier is correspondingly arranged at the top of both sides of the foundation pit, the embedded steel plate is arranged on the top of the concrete pier, and the steel ear plate is vertically welded to the top of the embedded steel plate.

[0007] In particular, the cable assembly includes a steel cable and a basket bolt. Two steel ear plates are respectively connected to a steel cable. The ends of the two steel cables away from the steel ear plates are respectively connected to the two ends of the basket bolts, and the cable force is adjusted by the basket bolts.

[0008] In particular, a plurality of nylon slings are vertically hung on the steel cable at equal intervals, and the communication pipeline is hoisted at the lower end of the nylon slings.

[0009] A construction method of a zipper-type communication pipeline protection structure comprises the following steps:

[0010] Step 1: Design the cable force calculation formula;

[0011] ;

[0012] F1=G / 2;

[0013] ;

[0014] Where, F is the cable force of the cable;

[0016] θ is the angle between the communication pipeline and the cable and the horizontal line;

[0017] G is the total weight of the communication pipeline and nylon sling;

[0018] h is the mid-span vertical displacement of the communication pipeline and the steel cable;

[0019] L is the horizontal distance between two steel lugs;

[0020] Step 2: According to the cable force F of the cable calculated in step 1, select a cable that meets the requirements;

[0021] Step 3: Carry out the construction of the pier assembly. After the concrete in the pier assembly reaches the designed strength, install the cable assembly;

[0022] Step 4: Perform cable tension adjustment construction, use the turnbuckle bolt to adjust the cable tension of the steel cable, during this process, use the cable tension meter to monitor the cable tension in real time to achieve accurate control of the cable tension of the steel cable, and stop adjusting the turnbuckle bolt when the cable tension reaches the cable tension F calculated in step 1;

[0023] Step 5: Install the nylon sling, hang the communication pipeline at the lower end of the nylon sling, and then carry out the construction of the foundation pit.

[0024] The beneficial effects of the present invention are as follows: by arranging pier assemblies, cable assemblies, and nylon slings, the present invention makes the pipeline protection structure simple in form, convenient in construction, small in occupied area, low in cost, convenient in transportation, and highly flexible in use; and the communication pipeline is suspended by the nylon sling, which is not easy to cause damage to its surface; at the same time, by designing a cable force calculation formula, the total weight of the communication pipeline and the nylon sling can be used to easily select a steel cable that meets the conditions and calculate the corresponding cable force, which can effectively control the deformation of the communication pipeline and ensure its normal use function, effectively improve the efficiency of program formulation and implementation, and have the effect of reducing costs and increasing efficiency.

[0029] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0030] The present invention will be further described below in conjunction with embodiments:

[0031] like Figure 1-Figure 2 As shown, a cable-type communication pipeline protection structure includes a column pier assembly 1, a cable assembly 2, and a nylon sling 5; the column pier assembly 1 is correspondingly arranged at the top of both sides of the foundation pit 3, the cable assembly 2 is connected between the column pier assemblies 1, and a plurality of nylon slings 5 ​​are hung on the cable assembly 2, and the communication pipeline 4 is hoisted by the nylon sling 5; the column pier assembly 1 includes a concrete column pier 101, an embedded steel plate 102, and a steel ear plate 103, the concrete column pier 101 is correspondingly arranged at the top of both sides of the foundation pit 3, the embedded steel plate 102 is arranged At the top of the concrete pier 101, a steel ear plate 103 is vertically welded to the top of the embedded steel plate 102; the cable assembly 2 includes a steel cable 201 and a basket bolt 202, and each of the two steel ear plates 103 is connected to a steel cable 201, and the ends of the two steel cables 201 away from the steel ear plates 103 are respectively connected to the two ends of the basket bolts 202, and the cable tension is adjusted by the basket bolts 202; a number of nylon slings 5 ​​are vertically hung on the steel cable 201 at equal intervals, and the communication pipeline 4 is hoisted at the lower end of the nylon sling 5.

[0032] In order to effectively control the deformation of the communication pipeline 4 and ensure its normal use function, it is necessary to control the vertical displacement of the pipeline in the middle of the span within a certain range. Although the total weight of the communication pipeline 4 and the nylon sling 5 is evenly distributed along the length direction of the cable assembly 2, treating the total weight of the communication pipeline 4 and the nylon sling 5 as a concentrated load acting on the middle of the span of the cable assembly 2 is conducive to simple calculation and is more conservative. Secondly, due to the small total weight, it has little effect on the selection of the steel cable 201.

[0033] A construction method of a zipper-type communication pipeline protection structure comprises the following steps:

[0034] Step 1: If Figure 3 As shown, the design cable force calculation formula;

[0035] ;

[0036] F1=G / 2;

[0037] ;

[0038] Wherein, F is the cable force of the cable 201;

[0039] F1 is the vertical component of the cable force; the horizontal component is F2;

[0040] θ is the angle between the direction of the communication pipeline 4 and the steel cable 201 and the horizontal line;

[0041] G is the total weight of the communication pipeline 4 and the nylon sling 5;

[0042] h is the mid-span vertical displacement of the communication pipeline 4 and the steel cable 201;

[0043] L is the horizontal distance between the two steel ear plates 103;

[0044] Step 2: According to the cable force F of the steel cable 201 calculated in step 1, a steel cable 201 that meets the requirements is selected; the cable force F of the steel cable 201 is multiplied by the coefficient specified in the specification to select a steel cable 201 that meets the requirements;

[0045] Step 3: construct the pier assembly 1, and after the concrete in the pier assembly 1 reaches the designed strength, install the cable assembly 2;

[0047] Step 5: Install the nylon sling 5, hang the communication pipeline 2 at the lower end of the nylon sling 5, and then construct the foundation pit 3.

[0048] The present invention arranges a pier assembly 1, a cable assembly 2, and a nylon sling 5, so that the pipeline protection structure is simple in form, easy to construct, small in occupied area, low in cost, convenient in transportation, and highly flexible in use. In addition, the communication pipeline 4 is suspended by the nylon sling 5, and it is not easy to cause damage to its surface. At the same time, by designing a cable force calculation formula, the total weight of the communication pipeline 4 and the nylon sling 5 can be used to easily select a steel cable 201 that meets the conditions, and calculate the corresponding cable force, which can effectively control the deformation of the communication pipeline 4, ensure its normal use function, effectively improve the efficiency of program formulation and implementation, and have the effect of reducing costs and increasing efficiency.
