Road street light foundation construction methods

Abstract

This invention relates to the field of building construction, specifically to a method for constructing road street light foundations. Based on a designed auxiliary tool for casting, the method reduces the excavation area, earthwork volume, and subsequent backfilling tasks. It eliminates the need for formwork, thus avoiding issues such as formwork displacement and bulging. The bottom support plate is easy to level and provides good support, ensuring flange stability and preventing construction disturbances, while also guaranteeing the horizontality of the embedded anchor bolts. Earthwork backfilling can commence immediately after the concrete has initially set and lifted out of the bottom support plate, significantly reducing earthwork storage and dust control work, thereby lowering costs.

Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a method for constructing road street light foundations. Background Technology

[0002] Urban lighting not only adds color to the city, highlights its cultural characteristics, and enhances its image, but also enriches residents' nightlife and improves their sense of well-being. In the construction of streetlights, especially the foundation, the traditional method involves excavating the foundation trench in reverse after the road surface and curb stones are completed, manually erecting the casting template, fixing the anchor bolts, and pouring concrete. However, existing patent CN220013678U – a streetlight foundation pouring auxiliary tool – utilizes a front template, rear template, left template, and right template to assemble a casting box. The bottom of the casting box has four adjustable screw feet used to adjust its stability after being placed in the foundation pit. Furthermore, auxiliary lateral supports are welded to the outer sides of the left and right templates, which, in conjunction with the pit sidewalls, provide temporary positioning. Once the streetlight foundation is suspended on the foundation suspension rod, concrete is poured into the casting box to complete the streetlight foundation construction.

[0003] Traditional methods have many shortcomings. The amount of earthwork excavated is large, which increases the difficulty of protecting the finished product on site. The large amount of earthwork stored also requires dust control measures, which increases costs. The erected formwork is prone to collapse and bulging during the pouring process, which increases construction difficulties. The four adjustable screw feet have poor support, which makes it difficult to control the level of the anchor bolts. The poor stability of the formwork makes the anchor bolts easy to be disturbed during construction, resulting in the anchor bolts exceeding the level tolerance and affecting the later installation effect of the street lights. Summary of the Invention

[0004] To address the above-mentioned problems, this invention provides a method for constructing road street light foundations.

[0005] This invention provides a method for constructing road street light foundations, the method comprising:

A wire hole is also provided on the lower side of the foundation main mold.

[0007] Excavate the foundation trench according to the dimensions of the bottom support plate. After excavation, compact the bottom support plate into the foundation trench and level it during the compaction process.

[0012] Optionally, anchor holes are provided on the bottom support plate, and horizontal air bubbles are provided on the outer surface of the bottom support sleeve; the process of compacting the bottom support plate into the foundation trench and leveling it during the compaction process includes:

[0013] Place the bottom support plate in the foundation trench, tap the bottom support plate with a rubber mallet while observing the horizontal bubbles during the tapping process to level it. After leveling, insert anchor nails into the anchor holes to fix the bottom support plate and enhance its firmness.

[0014] Optionally, the threading hole is a vertically arranged elongated hole, and a groove is provided on the top edge of the bottom support sleeve opposite to the threading hole; the process of the bottom end of the pre-embedded threading pipe passing through the threading hole and exiting the foundation main mold includes:

[0016] Optionally, lifting handles are provided on the bottom support plate and the top edge of the base main mold to facilitate lifting upwards.

[0017] Optionally, a release agent may be applied to the inner surface of the foundation formwork before pouring concrete into it. Attached Figure Description
