Problems solved by technology

[0003] The invention whose authorized announcement number is "CN 109442099 A" solves the problem that the installation of the pipeline is not fixed enough, but it has disadvantages: 1) it is limited to the space state, and does not consider the reinforcement method when laying on the ground; 2) the installation components are complicated; 3) The fixing device is exposed, the air corrosion is serious, and the service life is reduced
The authorized announcement number is "CN 109869531 A", which relates to a technology of oil pipeline fixing device. This invention has a fixed ground device, which is convenient for pipeline installation and protection, but there are also shortcomings: 1) it is not conducive to weak soil foundation; 2) the foundation and The interface of the ground fixing device is a weak surface; 3) After backfilling, the underground device will be eroded by the soil and the service life will be reduced

Embodiment 1

[0044] A pipeline installation method is provided: firstly, it is necessary to determine the construction location, excavate the foundation pit with a long-arm excavator, excavate in layers and sections, excavate the excavated earth and load it away by truck; backfill and compact the over-excavated part to the design height to ensure the foundation Meet the design strength requirements, and ensure the flatness of the excavation surface; after the foundation trench is repaired, remove the debris and floating soil on the foundation, and use the sand and gravel cushion as the foundation cushion to form a construction trench.

[0045] Further, after the excavation of the construction trench is completed, the operator needs to lay the pipeline concave flexible base at equal intervals along the pipeline laying length of 1000mm and place it on the center line of the trench. The concave flexible base of the pipeline is filled with sand, pulverized coal Gray and other flexible materials...

Embodiment 2

[0051] refer to Figure 1-4 , provides a flexible anti-floating device for pipelines, including a groove assembly 100, including a base groove 101, a base 102 disposed in the base groove 101, and a placement groove opened on the base 102; a pipeline anchor assembly 200, It includes a rod body 201, an octagonal nut 202 arranged at the upper end of the rod body 201, and a drill bit 203 arranged at the lower end of the rod body 201. A helical blade 204 is arranged between the drill bit 203 and the rod body 201. and the buckle assembly 300, the buckle assembly 300 is arranged between the pipeline and the rod body 201, the diameter of the bottom of the helical blade 204 is the same as that of the rod body 201, the diameter of the top of the helical blade 204 is 2-3 times the diameter of the rod body 201, and the helical The height of the blade 204 is 2-3 times the transverse diameter of the helical blade 204. The buckle assembly 300 includes a number of prisms 301 arranged at the u...

Abstract

The invention discloses a pipeline mounting method. The method comprises the following steps: uniformly excavating a foundation trench in a segmented and layered manner, and leveling; laying pipeline concave flexible bases at the bottom of the foundation trench at equal intervals; determining the drilling position and drilling a pull anchor rod body; and performing section-by-section quality inspection on to-be-used pipe sections according to product standards, hoisting the pipe sections by adopting a crane, and placing the pipeline perpendicular to the groove edge and stably cushioning the pipeline. A flexible clamping belt is used for fixing, fluidized soil is used for backfilling, the structure is reasonable, manual installation is convenient, the reinforcing effect is durable, environment protection is facilitated after soluble plastic is degraded, the strength of the hardened fluidized soil is fully utilized, the problem that a pipeline anchoring device is exposed or buried in soil to be damaged is well solved by backfilling the foundation trench with the fluidized soil, the solidified and hardened fluidized soil has extremely high strength, and the pipeline mounting effect is extremely good.

Description

technical field [0001] The invention relates to the technical field of pipeline installation, in particular to a pipeline flexible anti-floating device and a pipeline installation method. Background technique [0002] Existing pipeline fixing devices all adopt a single fixing method during the fixing process, and the contact area during fixing is small, which will lead to a greater degree of stress on the stressed point of the pipeline, thereby easily causing damage to the pipeline. Since the pipeline is a hollow entity, it will appear in a floating state in the liquid. Now a solution is needed to ensure that the pipeline does not float when pouring fluidized soil in the foundation trench. [0003] The invention whose authorized announcement number is "CN 109442099 A" solves the problem that the installation of pipelines is not fixed enough, but has disadvantages: 1) It is limited to the space state, and does not consider the reinforcement method when laying on the ground; 2...
