Problems solved by technology

[0003] In the prior art, due to precipitation infiltration and groundwater erosion, it is easy to cause the soil layer to loosen. Over the years, underground cavities may be generated, and local collapse occurs under the pressure of the ground load. When the collapse occurs, the soil layer or stones above the pipeline will The impact of the pipeline causes damage to the pipeline, so how to prevent the impact of precipitation on the municipal pipeline due to precipitation infiltration and groundwater erosion needs to be solved

Embodiment 1

[0036] like Figure 1-Figure 5 As shown, a construction technique for protecting municipal pipelines includes the following steps:

[0037] Step 1: First, excavate the trench along the pre-made municipal pipeline laying direction mark on the pre-selected road section. The depth and width of the excavated trench need to be greater than the diameter of the municipal pipeline itself. The depth and width of the excavated trench The sizes are 80cm-100cm and 50cm-70cm respectively;

[0038] Step 2: Then excavate two empty grooves on both sides of the trench excavated in step 1, and dig a horizontal placement groove at the bottom of the trench to ensure that the width of the placement groove is greater than the width of the groove;

[0039] Step 3: Then use the drilling equipment to drill multiple fixing holes at equal intervals on both sides of the empty slot in step 2 and the placement slot;

[0040] Step 4: Then build the trenches excavated in steps 1 and 2, the side walls of th...

Embodiment 2

[0052] A construction technique for protecting municipal pipelines, comprising the following steps:

[0053] Step 1: First, excavate the trench along the pre-made municipal pipeline laying direction mark on the pre-selected road section. The depth and width of the excavated trench need to be greater than the diameter of the municipal pipeline itself. The depth and width of the excavated trench The sizes are 90cm and 60cm respectively;

[0054] Step 2: Then excavate two empty grooves on both sides of the trench excavated in step 1, and dig a horizontal placement groove at the bottom of the trench to ensure that the width of the placement groove is greater than the width of the groove;

[0055] Step 3: Then use the drilling equipment to drill multiple fixing holes at equal intervals on both sides of the empty slot in step 2 and the placement slot;

[0056] Step 4: Then lay waterproof and anti-corrosion cement on the trenches excavated in steps 1 and 2, the empty grooves and the...

Embodiment 3

[0061] A construction technique for protecting municipal pipelines, comprising the following steps:

[0062] Step 1: First, excavate the trench along the pre-made municipal pipeline laying direction mark on the pre-selected road section. The depth and width of the excavated trench need to be greater than the diameter of the municipal pipeline itself. The depth and width of the excavated trench The sizes are 90cm and 60cm respectively;

[0063] Step 2: Then excavate two empty grooves on both sides of the trench excavated in step 1, and dig a horizontal placement groove at the bottom of the trench to ensure that the width of the placement groove is greater than the width of the groove;

[0064] Step 3: Then use the drilling equipment to drill multiple fixing holes at equal intervals on both sides of the empty slot in step 2 and the placement slot;

[0065] Step 4: Then coat the trenches excavated in steps 1 and 2, the side walls of the empty slots and the placement slots, and t...

Abstract

The invention relates to a construction process for protecting municipal pipelines. The construction process specifically comprises the following steps of: step 1, marking along the laying direction of the municipal pipelines which are made in advance to excavate a groove; step 2, excavating two empty grooves on two sides of the excavated groove; step 3, drilling a plurality of fixing holes on two sides of the empty grooves and a placing groove at equal intervals; step 4, building waterproof and anticorrosive cement on the side walls of the groove, the empty grooves and the placing grooves and the inner walls of the plurality of fixing holes drilled in the step 3; step 5, putting the arranged and mounted municipal pipelines into the built groove; and step 6, building and laying a shelter on the flattened top. The side walls of the groove, the empty grooves and the placing groove and the inner walls of the fixing holes are all built with the waterproof and anticorrosive cement or coated with an anti-freezing solution, and some heat preservation pads and buffering pads are fixedly laid on the outer sides, so that the waterproof supporting protection effect on the municipal pipelines is achieved, and the influence of rainfall permeation and underground water erosion on the municipal pipelines is prevented.

Description

technical field [0001] The invention relates to the technical field of municipal road pipeline construction, in particular to a construction technique for protecting municipal pipelines. Background technique [0002] The density of urban population is increasing, and urban buildings are becoming more and more dense, which makes the density of urban underground pipelines gradually increase. With the rapid development of urban traffic, the number of urban road construction and the density of urban roads are also gradually increasing. The pipeline is directly related to people's livelihood. If it is damaged, it will affect the production and life of residents, increase traffic congestion, and affect residents' travel. Therefore, properly handling the laying of pipelines under municipal roads plays an important role in improving the quality of life of residents. Meaning, municipal road pipelines are buried underground, and the underground of municipal roads provides space for la...
