Problems solved by technology

Municipal roads and rainwater wells in residential quarters are mostly brick-built wells. Brick-built wells are mainly made of bricks, sand and cement. The inside and outside of the wells are plastered. The compressive strength of the well is low, and the ash joints of the brick rainwater well are easy to fall off and crack after a long period of use.
However, the construction sequence of traditional concrete wells is mostly surveying and setting out-pipe trenches, excavation of rainwater wells-pouring of rainwater well cushions-formwork support-pouring concrete-curing-formwork removal-piping-backfilling, in which wooden formwork support and The demolition is complicated and cumbersome, it takes a lot of time, the loss rate after the formwork is removed is high, it is difficult to control the connection time between various processes, and it is difficult to implement large-scale flow construction

Embodiment 1

[0040] Such as Figure 1 to Figure 4 Shown, a kind of concrete rainwater well construction method that utilizes steel pipe to make inner formwork is characterized in that, comprises specific following steps:

[0041] Step 1: HDPE rainwater pipe 4 installation

[0042] 1) Measuring and setting out: according to the direction and elevation of the pipeline in the drawing, use lime wire to release the direction and position of the pipeline and tube well respectively; excavate a circular well pit with a diameter of φ1400 at the position of the tube well, and spread lime line at the center of the well pit. On the "ten"-shaped mark, the depth of the well pit should be based on the drawing design plus 100mm as the rainwater well cushion;

[0043] 2) Excavation of pipe trench 5 and rainwater well: according to the design requirements of the construction drawings, use excavator to excavate pipe trench 5 and rainwater well;

[0044] 3) Fine sand laying: The original soil at the rainwat...

Abstract

The invention discloses a concrete rainwater well construction method using a steel pipe as an inner mold. The specific steps of the method include installing HDPE rainwater pipes, making the inner mold of the rainwater well, making and installing a baffle plate, pouring concrete, removing the inner mold of the rainwater well, and backfilling pipe trenches. The invention is applicable to the construction of rainwater wells and sewage wells in municipal or residential areas, improves the compressive strength and durability of rain masonry structures, simplifies procedures, shortens construction period, and reduces costs.

Description

Technical field: [0001] The invention belongs to the technical field of municipal construction, and in particular relates to a construction method for a concrete rainwater well using a steel pipe as an inner mold. Background technique: [0002] At present, with the rapid growth of my country's economic level in recent years, the urbanization process has steadily advanced, and the residential quarters and municipal roads in various cities have increased rapidly. Municipal roads and residential roads generally use asphalt pavement or concrete pavement. Because the asphalt pavement or concrete pavement is hard pavement, although it is neat and durable, it is impermeable. In addition, drainage depends on underground drainage pipes, and each drainage pipe is connected through a rainwater inspection well. On the one hand, the rainwater well can solve the need for cleaning up the silt accumulated in the underground drainage pipes after long-term use; Steering station. Municipal r...
