Embodiment Construction

[0031] In order to better understand the present invention, below in conjunction with embodiment and accompanying drawing, technical scheme of the present invention is described further (as Figure 1-8 shown).

[0032] Such as figure 1 , 2 , 3, 4, a template for reserved foundation pits for inspection wells, including circular templates, according to the depth (20CM) and size (diameter 170CM) of foundation pits that need to be excavated in the road base, the outer diameter is 170CM and the effective height is made 18CM circular formwork, the circular formwork is made of rubber, with multi-layer canvas net inside. The lower surface of the circular template is provided with a circular spigot 2 that matches the wellhead of the inspection well, and the circular spigot 2 is a circular boss with a concentric blind hole (about 50 cm in diameter and about 50 cm in depth) in the middle. 18CM), the outer diameter of the circular stop 2 (about 70CM) is slightly smaller than the inner ...

Abstract

The invention belongs to the technical field of municipal road construction, and in particular relates to a formwork and a method for reserved foundation pits for inspection wells. A template for reserved foundation pits for inspection wells, comprising a circular template, the lower surface of the circular template is provided with a circular stop that matches the wellhead of the inspection well; the circular template is divided into two along the diameter, and divided into Two semicircular templates. The circular formwork is made of rubber, and a multi-layer canvas net is arranged inside. The upper surface of the semicircular template is provided with a plurality of lifting rings, and the lifting rings are embedded in the semicircular template. The inside of the circular template is provided with multiple rings of annular cavities distributed from outside to inside, and the multiple rings of ring cavities share the same center as the circular template. It is used to solve the problems of inconvenient, time-consuming and labor-intensive use of temporary manhole covers in the traditional inspection well construction scheme.

Description

technical field [0001] The invention belongs to the technical field of municipal road construction, and in particular relates to a formwork and a method for reserved foundation pits for inspection wells. Background technique [0002] With the continuous improvement of the degree of urban modernization, there are more and more public pipelines in various cities, and the inspection wells of various pipeline networks on the municipal roads are also increasing. In the traditional inspection well construction plan, when laying the road base (cement stable layer), a steel plate (or other load-bearing objects) with a slightly larger diameter is placed at the wellhead to cover the wellhead as a temporary manhole cover, and the road is marked. The base layer is paved and rolled to prevent compaction dead ends. After the maintenance period of the road base layer expires, the foundation pit is excavated from the inside to the outside at the wellhead of the inspection well, the tempora...
