CN101956421B - Fast diversion method of drain pipe in drainage construction - Google Patents

Abstract

The invention relates to a diversion method of a drain pipe in drainage construction, in particular to a fast diversion method of a drain pipe in drainage construction, which is characterized by comprising the following steps: 1) excavation: firstly excavating earthwork at intersection of newly-built pipelines and old pipelines, cleaning out the earthwork around the old pipelines at the intersection by manpower, and exploding the tops of the old pipelines within a well chamber of the newly-built pipelines; 2) installation of draft pipes: placing the draft tubes on the tops of the old pipelines, and filling soils to reach compact covering in the gap between the old pipelines and the draft tubes at the same time; and 3) elimination of the old pipeline: starting to eliminating the old pipelines within the well chamber of the newly-built pipelines after the draft tubes are placed, and constructing the well chamber of the newly-built pipelines in accordance with the design drawing. The diversion method of the invention has the advantages of practicality, simplification, fastness, and low cost.

Description

The quick method of river diversion of gutter in the drainage construction

Technical field

The present invention relates to the method for river diversion of gutter in the drainage construction.

Background technology

At present, in the municipal engineering drainage construction, newly-built gutter often need pass old gutter, and the water of old gutter need be guided in the newly-built drainage pipe simultaneously.Traditional method is to do in the upstream of old pipeline to dam, and with foul water pump water is guided in the new pipeline, and the old pipeline that will influence new pipeline construction is then abolished, and new pipeline is installed and is built by laying bricks or stones the well chamber.If do not have power supply or power failure suddenly, then water conservancy diversion can't be constructed.

Summary of the invention

The object of the present invention is to provide a kind of practicality simply, the quick method of river diversion of gutter in the drainage construction fast.

For achieving the above object, the technical solution used in the present invention is: the quick method of river diversion of gutter in the drainage construction is characterized in that it comprises the steps:

1) excavation: at first, manually the earthwork around the old pipeline of intersection is cleaned out, then the top of the old pipeline in the well chamber scope of newly-built pipeline is abolished with cubic metre of earth the excavating of newly-built pipeline and old pipeline intersection;

2) mozzle is installed: lay mozzle from the top of old pipeline, the filling mount is closely knit in the space of old pipeline and mozzle simultaneously;

3) abolish old pipeline: after treating that mozzle places, begin to abolish the old pipeline in the well chamber scope of newly-built pipeline, then according to the construct well chamber of newly-built pipeline of design drawing.

The invention has the beneficial effects as follows: adopt mozzle that the part of abolishing of old pipeline is communicated with, water is guided in the new pipeline without foul water pump; The present invention is practical simply, quick, cost is low.

Description of drawings

Fig. 1 is the water conservancy diversion schematic diagram of gutter;

Fig. 2 is the vertical view of Fig. 1;

Among the figure: the old pipeline of 1-, the 2-mozzle, the 3-mount, the newly-built pipeline of 4-, 5-abolishes part, 6-well chamber.

The specific embodiment

Be described in detail the present invention below in conjunction with accompanying drawing:

As shown in Figure 1 and Figure 2, the quick method of river diversion of gutter in the drainage construction, it comprises the steps:

1) excavation:, manually, then (abolishing part 5) abolished at the top of the old pipeline in the well chamber scope of newly-built pipeline with cubic metre of earth cleaning out around the old pipeline 1 of intersection at first with cubic metre of earth the excavating of newly-built pipeline 4 and old pipeline 1 intersection;

2) installation mozzle: lay mozzle 2 (as shown in Figure 1, being communicated with) from the top of old pipeline 1, in the space of old pipeline 1 and mozzle 2, fill mount 3 closely knit (guaranteeing that sewage passes through from mozzle) simultaneously by the part of abolishing of mozzle with old pipeline;

3) abolish old pipeline: after treating that mozzle places, begin to abolish the old pipeline in the well chamber scope of newly-built pipeline, then according to the construct well chamber 6 of newly-built pipeline 4 of design drawing.

Claims (1)

1. the quick method of river diversion of gutter in the drainage construction is characterized in that it comprises the steps:

1) excavation: at first, manually the earthwork around the old pipeline of intersection is cleaned out, then the top of the old pipeline in the well chamber scope of newly-built pipeline is abolished with cubic metre of earth the excavating of newly-built pipeline and old pipeline intersection;

2) mozzle is installed: lay mozzle from the top of old pipeline, the filling mount is closely knit in the space of old pipeline and mozzle simultaneously;

3) abolish old pipeline: after treating that mozzle places, begin to abolish the old pipeline in the well chamber scope of newly-built pipeline, then according to the construct well chamber of newly-built pipeline of design drawing.
