Description
Technical Field
The utility model relates to the technical field of cable trench construction, in particular to a pouring template convenient for construction of a power pipe trench in a narrow space.
Background
With the development of informatization, the existing power pipeline faces the need of modification, and particularly the cable trench needs to be modified urgently in the busy old areas of large cities so as to meet the requirement of city development. But the transformation in busy places faces a plurality of problems:
firstly, there are many shops and plants distributed along the line, the distance between the electric power pipe ditch side line and the existing structure side line is 1-3m, and the periphery of the electric power pipe ditch side line is also provided with structures such as electric power poles and advertising boards, so that the construction area is narrow and small, and large-scale equipment cannot be put into the field.
Secondly, the precipitation of partial areas is large, the time of rainy season is from May to September every year, the underground water burial depth of the construction area is shallow according to the existing geophysical prospecting report, and the construction time of the power pipe trench is required to be shortened as much as possible under the conditions.
Thirdly, the most important point is that the construction schedule of 50m template segment construction of the power pipe trench is as shown in fig. 1, and the construction period needs 8 days, and the construction period proportion of each procedure is 7% of trench excavation, 6% of cushion layer construction, 31% of template installation, 31% of reinforcement binding and 25% of concrete pouring, and the construction procedures of template installation, reinforcement binding and concrete pouring are relatively large through analysis.
Therefore, in order to shorten the construction time of the power pipe trench in a narrow space, the end reasons of the above-mentioned processes, namely the two main reasons of "inconvenient template installation and splicing" and "narrow construction site", need to be analyzed. These two main factors are further analyzed below.
Factor analysis one: inconvenient installation and splicing of templates
The traditional wood formwork support has the defects of complicated mould process, multiple nail hammer processes, dense distribution of the power pipe trench supports, vertical 0.25m and horizontal 0.8m spacing of the cloth holes, and 72cm spacing between the two power pipe trench supports. The supports are densely distributed, and the space between the supports is narrow, so that the templates are inconvenient to manufacture, install and splice. After the test section wood template is installed, the periphery of the hole position of the support still needs to be plugged, slurry leakage is prevented, and the installation progress of the template is further slowed down.
Factor analysis two: narrow construction site
The red line of many places of this engineering investigation and the red line of land use coincide mutually, and the distribution shop along the line, factory building are more, very close to electric power trench construction area simultaneously. The excavation depth of the power groove is large, the foundation pit side slope stability and the surrounding building safety are guaranteed, so that the site slope excavation cannot be carried out, and the template installation area is very limited.
To sum up, the construction site is narrow and small and the inconvenience of template installation and splicing is the main factor that hinders the construction progress.
