With the rapid development of modern society, as an important part of urban infrastructure, the construction of underground pipe gallery has attracted more and more attention. As an important construction tool, the comprehensive pipe gallery mold is widely used in cast-in-place construction methods. This article will focus on the application of comprehensive pipe gallery mold in cast-in-place construction.
First, the introduction of the comprehensive pipe gallery mold.
The comprehensive pipe gallery mold is an important industrial tool, mainly used to manufacture prefabricated pipe gallery, and its main material is steel. Due to its special design, it is able to form various prefabricated parts after grouting, such as two meters, two meters.
Five, four meters, six meters and other different sizes of pipe gallery. These prefabricated pipe corridors are mainly used for the construction of underground pipe corridors in the city, providing centralized laying space for the city's electricity, communication, sewage, gas and other pipelines.
Second, the application of the comprehensive pipe gallery mold in cast-in-place construction.
1.Preparation before construction.
Before construction, it is necessary to select the appropriate comprehensive pipe gallery mold, and according to different construction needs, workers will go to the warehouse to register and use according to the model. At the same time, the construction site needs to be cleaned and leveled to ensure that the construction proceeds smoothly.
2.Installation and fixation of molds.
When installing and fixing the mold, it is necessary to follow the specified operation process to ensure the stability and safety of the mold. Under normal circumstances, the mold needs to be installed on a flat ground and fixed with a fixture to prevent displacement or deformation during the pouring process.
3.Preparation and pouring of concrete.
When preparing concrete, it is necessary to dose according to the specified mix ratio and ensure that the quality of the concrete meets the requirements. When pouring, it is necessary to inject the concrete evenly into the mold and ensure the compactness and uniformity of the concrete. During the pouring process, the mold also needs to be vibrated and troweld to prevent bubbles and uneven surfaces.
4.Curing and demoulding.
After pouring, the concrete needs to be cured and demoulded. During curing, the proper temperature and humidity need to be maintained so that the concrete can harden and solidify sufficiently. When demoulding, it is necessary to follow the prescribed operation process to avoid damage to the concrete.
5.Quality inspection and acceptance.
Finally, it is necessary to carry out quality inspection and acceptance of the prefabricated pipe gallery made. The inspection content includes appearance quality, dimensional accuracy, compressive strength, etc. After passing the acceptance, the subsequent installation and use can be carried out.
Third, the advantages and precautions of the comprehensive pipe gallery mold.
1.Merit.
The comprehensive pipe gallery mold has the advantages of high production precision, easy use and good durability. It can greatly improve the production efficiency and quality of the prefabricated pipe gallery, shorten the construction period and reduce the construction cost. At the same time, due to the use of the comprehensive pipe gallery mold, the excavation and damage to the urban road can be reduced, and the impact on the surrounding environment can be reduced.
2.Precautions.
When using the mold of the comprehensive pipe gallery, it is necessary to pay attention to the following points: first, it is necessary to choose the appropriate mold model and material to ensure that the construction needs are met; Secondly, the mold should be installed and fixed correctly to prevent the pouring process from shifting or deforming; Third, it is necessary to strictly control the mix ratio and quality of concrete to ensure the quality of pouring; Fourth, it is necessary to carry out curing and demoulding in accordance with the prescribed operation process to avoid damage to the concrete; Finally, it is necessary to do a good job in quality inspection and acceptance to ensure that the quality of the prefabricated pipe gallery meets the requirements.
