Example Embodiment

[0061] Example 1-4

[0062] A thermal insulation coating, which includes the following components:

[0063] Portland cement, talcum powder, fumed silica, hollow glass beads, barium complex, water, water reducing agent.

[0064] The input amount (unit Kg) of each component in Example 1-4 is shown in Table 2

[0065] Table 2

[0066]

[0067]

[0068] Reference figure 1 The preparation method of the thermal insulation coating in Examples 1-4 includes the following steps:

[0069] Step 01) Add Portland cement, water, and water reducing agent into the stirring tank, rotate at 60r / min, and stir for 5min to form cement slurry;

[0070] Step 02) Add talc powder to the cement slurry at a speed of 50r / min and stir for 8min to form a premix;

[0071] Step 03) Add fumed silica, hollow glass beads, and barium complex to the premix, at a speed of 35r / min, stir for 10min, to obtain a thermal insulation coating, at a speed of 15r / min, and continue stirring until the use is complete.

Example Embodiment

[0072] Example 5-8

[0073] Compared with Example 4, the only difference is:

[0074] The thermal insulation coating in Examples 5-8 also includes the following components:

[0075] Lithium fluoride.

[0076] The input amount (unit Kg) of each component in Examples 5-8 is shown in Table 3

[0077] table 3

[0078]

[0079]

[0080] In step 3), lithium fluoride is added to the premix together with fumed silica, hollow glass beads, and barium complex, and stirred uniformly.

Example Embodiment

[0081] Examples 9-12

[0082] Compared with Example 4, the only difference is:

[0083] The thermal insulation coating in Examples 9-12 also includes the following components:

[0084] Glass fiber, silane coupling agent.

[0085] The input amount (unit Kg) of each component in Examples 9-12 is shown in Table 4

Abstract

The invention relates to the field of pipeline mounting, in particular to a water drainage pipeline mounting process. The water drainage pipeline mounting process comprises the following steps: step 1) of excavating a pipeline mounting groove; step 2) of mounting a tube seat in the groove; step 3) of sequentially hoisting a plurality of pipeline units; step 4) of connecting adjacent pipeline unitsto form a water drainage pipeline; step 5) of coating thermal-insulation paint on the surface of the water drainage pipeline to form a thermal insulation layer; step 6) of backfilling soil and compacting the soil to form a pipeline soil layer, and controlling vertical height difference between the top of the pipeline soil layer and the top of the water drainage part to be 2cm-5cm; step 7) of spreading porous stones on the pipeline soil layer to form a stone heat insulation layer; and step 8) of backfilling soil into the stone heat insulation layer, and compacting the stone heat insulation layer to repair ground. The water drainage pipeline mounting process has the effects of enabling a water body in a water drainage tube to be not liable to ice and expand, and enabling the water drainagepipeline to be not liable to damage.

Description

technical field [0001] The invention relates to the technical field of pipeline installation, in particular to a drainage pipeline installation process. Background technique [0002] At present, with the development of the city, more and more people live in the city, which leads to a large increase in water consumption, which in turn leads to a large increase in drainage demand. Therefore, it is necessary to build a drainage network through drainage pipes to ensure the drainage function of the city. [0003] The installation of existing drainage pipes usually includes the steps of excavating trenches, installing pipe sockets, hoisting pipe units, connecting adjacent pipes, backfilling to repair the ground, etc. By burying the drainage pipes underground, the underground space can be effectively used and reduced Drainage pipes occupy the ground space and reduce the impact on people's normal activities. [0004] There are following defects in the above-mentioned prior art sche...
