Water collection pit anti-floating integral formwork system and installing method for formwork system

Abstract

The invention discloses a water collection pit anti-floating integral formwork system and an installing method for the formwork system. The formwork system comprises a coverless box type formwork anda supporting system arranged in the box type formwork, wherein the box type formwork is formed by assembling a plurality of side dies and a bottom die. The bottom die and the side dies are fixedly arranged on bottom steel bars and side face steel bars of a steel bar support correspondingly. The bottom die and the side dies are concrete prefabricated plates internally provided with steel bar nets,and a plurality of segmented water stop screws are arranged between the bottom die and the bottom steel bars and between the side dies and the side face steel bars, wherein the segmented water stop screws are distributed in a grid-like manner. A plurality of vibration holes are evenly distributed in the bottom die and between the water stop screws. During installation, the segmented water stop screws, the bottom die and the side dies are installed, and then the supporting system is arranged in the box type formwork formed by assembling the side dies and the bottom die. According to the obtained water collection pit anti-floating integral formwork system and the installing method for the formwork system, formwork removal is not needed, time and labor are saved for formwork installation, andthe construction period is short.

Description

technical field [0001] The invention relates to the anti-leakage technology of sump pits in building construction, in particular to an anti-floating integrated formwork system for sump pits and an installation method for the formwork system. Background technique [0002] When the foundation pit is excavated in construction engineering, if the groundwater level is relatively high and the base level is below the groundwater level, it is necessary to set up a sump pit, and excavate drainage ditches along the bottom of the pit or in the center to allow water to flow into the sump pit, and then Take it away with a sewage pump (submersible sewage pump). The cross section of the sump is U-shaped and consists of a bottom plate and a side wall. The sump is generally composed of a base layer, a concrete cushion, a waterproof layer and a reinforced concrete layer from the inside to the outside. When pouring the outermost reinforced concrete layer, according to the design elevation and...

Problems solved by technology

[0003] Due to the light weight and insufficient strength of the formwork in the above two methods, it is necessary to use anti-floating steel pipes or tie rods for anti-floating and side formwork support, and the number and density of settings are relatively large. In addition, the formwork needs to be concreted after use. Demolition after final setting and maintenance is time-consuming and labor-intensive, affecting the construction period

In addition, when pouring concrete, the concrete under the bottom form cannot be vibrated, which will affect the molding quality of the concrete
