Onshore integrated prefabricated bearing platform and production and mounting method thereof

Abstract

The invention discloses an onshore integrated prefabricated bearing platform which comprises a prefabricated bearing platform body and a plurality of first connecting reinforcing steel bars, the inside of the prefabricated bearing platform body is provided with a bearing platform reinforcement cage and a plurality of pile foundation reserved holes, pile foundation reserved hole reinforcing reinforcement cages are arranged around the pile foundation reserved holes, the first connecting reinforcing steel bars penetrates the inner wall of the pile foundation reserved holes, one end of each firstconnecting reinforcing steel bar extends in the bearing platform reinforcement cage, and the other end of each first connecting reinforcing steel bar is reserved into the pile foundation reserved hole. The reinforcing steel bar concrete is preformed, lifted and mounted in place, most of traditional bearing platform construction is transferred to a factory to be finished, the casting construction quality of concrete can be improved, raw materials and manual labor are saved, integrated process of bridge construction is accelerated, the prefabricated bearing platform and a pile foundation are effectively connected through the pile foundation reserved holes and the first connecting reinforcing steel bars, a prefabricated bearing platform is fixedly and reliably ensured, and the platform is used for the technical field of onshore bearing platforms.

Description

technical field [0001] The invention relates to the technical field of onshore caps, in particular to an onshore integral prefabricated cap and a production and installation method thereof. Background technique [0002] The traditional land cap adopts the construction mode of on-site pouring, that is, excavating the foundation pit→arranging the pile head reinforcement→constructing the cushion layer→binding the cap reinforcement→supporting the reinforcement formwork→pouring the cap concrete→maintenance→removing the formwork. There are the following technical disadvantages in the construction of the cap under the cast-in-place mode: (1) The construction quality of the concrete is difficult to control, and it is prone to common quality problems such as run-out, grout leakage, and vibration leakage, and the construction speed is slow, which affects the construction progress of the bridge superstructure; ( 2) The waste of raw materials such as cement, steel, and gravel is serious...

Problems solved by technology

There are the following technical disadvantages in the construction of the cap under the cast-in-place mode: (1) The construction quality of the concrete is difficult to control, and it is prone to common quality problems such as run-out, grout leakage, and vibration leakage, and the construction speed is slow, which affects the construction progress of the bridge superstructure; ( 2) The waste of raw materials such as cement, steel, and gravel is serious, the consumption of water, electricity, and gas is large, and brackets, formwork, and fasteners are easily lost, and the maintenance status is difficult to guarantee; (3) Many construction workers are required, and the labor intensity The construction environment is relatively large, and the construction environment is greatly affected by the natural environment. In rainy, snowy, high temperature, and cold weather, the construction of the platform is affected, and the working environment of the workers is poor; (4) A large amount of concrete cast-in-place construction will easily cause noise pollution to the surrounding environment , generating a large amount of construction waste
