Problems solved by technology

[0004] The closing section of the pipeline usually chooses a straight line section. Due to the influence of the position during the installation of the gantry, the reserved length of the closing section is relatively large, so that the 2~3 sections of PCCP cannot be installed according to the pipe arrangement table, and a large-tonnage crane must be rented separately for closing. increased construction costs

Embodiment 1

[0021] Example 1, such as Figures 1 to 2 As shown, the structure of the closing section of the large-diameter PCCP water pipeline includes closing port 5, front-end pipeline 6, back-end pipeline 7, front-end track 8, back-end track 9 and accompanying road 10; front-end pipeline 6 and back-end pipeline 7 are both straight lines Pipeline, the front-end pipeline 6 and the rear-end pipeline 7 are arranged at an angle, and there is a gap at the intersection of the front-end pipeline 6 and the rear-end pipeline 7 to form a closing port 5; the front-end track 8 is distributed along the axis of the front-end pipeline 6 in the front-end pipeline 6 On both sides of the rear-end pipeline 7, the rear-end track 9 is distributed on both sides of the rear-end pipeline 7 along the axis of the rear-end pipeline 7; Accompanying road 10; the end of the front end track 8 located at the closing port 5 is connected with a deflection track 11 that is offset to the side of the accompanying road 10 a...

Embodiment 2

[0034] Embodiment 2, the installation method of the large-diameter PCCP water pipeline closing section pipe layout, including the first step: select the position of the closing pipe in the pipeline, and use the inflection point of the pipeline as the closing section; the second step: reserve the space for installing the closing pipe Closing mouth 5; Step 3: Lay the front track 8 forward along the reserved closing mouth 5, and lay the rear track 9 backward; Step 4: erect the gantry through the rear track 9, facing or away from the closing mouth 5 Install the PCCP pipes sequentially in the direction to form the back-end pipeline 7; the fifth step: erect the gantry through the front-end rail 8, install the PCCP pipes in sequence toward the reserved closing port 5, and reserve the last one to two PCCP pipe joints; Step 6: At the opening 5, extend and deflect the front-end track 8 so that the formed deflection track 11 bypasses the port of the rear-end pipeline 7; Step 7: The bendin...

Abstract

The invention relates to a large-diameter PCCP water delivery pipeline closure section framework and a mounting method, in particular to a large-diameter PCCP water delivery pipeline closure section framework and a pipe arrangement mounting method. The framework comprises a closure opening, a front-end pipeline, a rear-end pipeline, a front-end track, a rear-end track and an accompanying road, the front-end pipeline and the rear-end pipeline are both linear pipelines, the front-end pipeline and the rear-end pipeline are arranged at an included angle, and a notch is reserved at the intersection of the front-end pipeline and the rear-end pipeline to form a closure opening. Due to implementation of a technical scheme, a turning point of the pipeline is selected as the closure opening, a deflection track bypassing an end opening of the rear-end pipeline is formed at an end opening of the front-end track by adopting an extension or deflection method, the deflection track matches the accompanying road and a descending slope, so that a pipe conveying vehicle can be backed into the descending slope, a portal frame unloads a pipe to mount the complete front-end pipeline, due to the fact that a closure pipe is manufactured in sections, closure installation can be completed only through a small-tonnage truck crane during closure, and construction cost is saved.

Description

technical field [0001] The present application relates to an installation structure and installation method of a closing section of a large-diameter PCCP water delivery pipeline, and in particular to a structure and a method for installing a closing section of a large-diameter PCCP water delivery pipeline. Background technique [0002] In order to improve the installation progress of the large-diameter PCCP water pipeline project, the same pipeline is usually installed on multiple working faces at the same time. , Width and the length of the closing place, the number of PCCP installed at the closing place is limited, resulting in the need to rent a large-tonnage crane separately for PCCP installation and steel pipe fittings closing. [0003] Large-diameter PCCP single section weighs about 50 tons (take DN3400 as an example), affected by the geographical environment of the installation work surface, when using crawler cranes for installation, considering safety, at least 280 ...
