Embodiment 1

[0023] Embodiment 1 Pipeline update method from outdoor to indoor:

[0024] (1) Outdoor opening

[0025] The outdoor opening means excavating the working pit outdoors. According to the orientation of the pipeline, digging the working pit outdoors is convenient for drilling rig construction. The size of the working pit is set at 1500×1500×1000.

[0026] (2) Horizontal drilling

[0027] After the working pit is excavated, hoist the horizontal directional drilling equipment into the working pit with a crane, level it manually according to the requirements of the pipeline, install the guiding head on the front end of the drill pipe, cooperate with the guiding instrument to carry out drilling jacking, and strictly control the direction and elevation. Enter a drill pipe for inspection once, and adjust quickly if there is any deviation.

[0028] (3) Indoor opening

[0029] Indoor opening means vertical drilling indoors. This method adopts the non-excavation crossing construction m...

Embodiment 2

[0036] Embodiment 2 The pipeline update method from indoor to outdoor:

[0037] (1) Indoor opening

[0038] The indoor opening is the indoor inclined drilling. The inclination angle is 25 degrees. The equipment used when opening the indoor hole is a bolt drill, which is inclined to drill outwards. The diameter of the drilling hole is 200mm. The indoor opening is above the original riser elevation. Move 15cm.

[0039] (2) Horizontal drilling

[0040] Install the drill pipe at the front end of the rock bolter, install the guide head at the front end of the drill pipe, cooperate with the guiding instrument to carry out drilling jacking, strictly control the direction and elevation, check each time a drill pipe is jacked, and adjust it quickly if there is any deviation.

[0041] (3) Outdoor opening

[0042] The outdoor opening is to excavate the working pit outdoors. After the drill bit reaches the outdoor target position, the working pit is excavated around the drill bit. The ...

Abstract

The invention provides an updating method for an indoor pipeline. The updating method comprises the following steps: forming indoor holes and outdoor holes; drilling the holes; mounting the pipeline; testing pressure; backfilling a working pit. The updating method for the indoor pipeline has the beneficial effects that the updating method is adopted when the indoor pipeline is exchanged, the influence on the surrounding environment caused by the pipeline exchange is settled, the updating for the indoor pipeline is realized without large-area digging, the method is low in cost and the construction is convenient.

Description

technical field [0001] The invention belongs to the field of engineering, and in particular relates to a method for updating indoor pipelines. Background technique [0002] In the interior of old residential buildings or factories, municipal public pipelines are often unable to be reused due to corrosion or disrepair for a long time, and new pipelines need to be replaced. The existing method is to dig the ground path of the original pipeline to take out the original pipeline and lay a new one. The pipelines involved in the large-scale excavation of residents or factories will have a great impact on the lives of residents or the production of factories. Contents of the invention [0003] The purpose of the present invention is to solve the impact of pipe replacement on the surrounding environment, and provide a method for renewing indoor pipes without large-area excavation. [0004] The technical scheme of the present invention is: a kind of indoor pipeline updating method...
