Problems solved by technology
However, the artificial support formwork has the disadvantages of construction safety and construction period: (1) the manual operation speed is slow, and the operation quality is unstable
(2) The traffic flow on the road is huge and there are many construction workers, so the safety risk is great
(3) Concrete needs to be removed after equal strength, and the construction period is long
(4) There are many turnover materials, and the formwork cannot be reused after the foundation construction is completed
(5) The template is fixed on the existing road surface with nails, which will cause damage to the road surface

Embodiment Construction
[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0025] See Figure 1-Figure 4 , the urban road enclosure large-section concrete foundation sliding form construction method specifically includes the following steps:
[0026] (1) Construction lofting: the middle piles are released accurately every 200m, and the J2 theodolite is used to release the 10m middle piles accordingly, and the design distance to both sides is used to determine the sidelines of the enclosure foundation. Before construction, steel brazi...

The invention discloses an urban road fence large-section concrete foundation slip-form construction method which adopts a slip-form machine pouring mode, a special fence foundation mold is arranged on a slip-form machine, and in the linear walking process of the slip-form machine, concrete extruded by the special fence foundation mold is automatically poured and formed; a purpose of rapid pouring forming of the fence large-section concrete foundation is achieved, construction cost is reduced, and construction efficiency of the fence foundation is greatly improved.
Description
technical field [0001] The invention relates to the construction field of road enclosures, in particular to a sliding form construction method for large-section concrete foundations of urban road enclosures. Background technique [0002] Due to the need to occupy the existing road during the construction stage, the construction on the existing road will face the problem of closed enclosure at the construction site. In order to ensure the safety of construction and traffic, the enclosure must be provided with a solid and reliable concrete foundation. At present, the construction of urban road fences at home and abroad is relatively common. The conventional method is to use artificial support formwork to pour concrete foundations. After the pouring is completed, expansion screws and diagonal braces are used to fix the fence pieces. However, artificial support formwork has disadvantages of construction safety and construction period: (1) The manual operation speed is slow and t...
