Prefabricated caisson mold construction method capable of replacing brick forming die with mucky soil

Abstract

The invention discloses a prefabricated caisson mold construction method capable of replacing a brick forming die with mucky soil, and relates to the technical field of buildings. The prefabricated caisson mold construction method capable of replacing the brick forming die with the mucky soil comprises the following specific operation steps that S1, a current geological condition is judged, and if the mucky soil is very poor in cohesive force, prone to collapse and large potential safety hazards are caused, the step S2 is carried out; according to the prefabricated caisson mold construction method capable of replacing the brick forming die with the mucky soil, a caisson type steel mold is prefabricated in advance, the mold can be immediately hoisted in place after a foundation pit is excavated, the risk of slope collapse is prevented, the safety of elevator shaft and water-collecting well earth excavation is ensured, the engineering cost is reduced, the later maintenance cost is eliminated, the soft foundation bed forming die can replace a brick forming die, can play a role in protecting a wall, prevents earthwork collapse, forms a whole with a cushion layer, is good in waterproof performance and integrality, and can prevent the soft foundation bed layer from sinking and cracking due to uneven settlement.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a construction method for a prefabricated caisson mold in which muddy soil can replace brick tire molds. Background technique [0002] At present, with the development of the economy, the scale of the city is getting bigger and bigger, the residents are more and more concentrated, and the number of high-rise buildings is increasing. In areas with poor soil quality, in order to meet the foundation bearing capacity requirements of high-rise buildings, piled raft foundations are usually used. However, the elevations of the water collection wells and elevator shafts are relatively high and do not reach the bearing layer. In addition, there are more rainwater and rivers in the south, and generally the soil is mostly muddy, which poses great difficulties to the construction of elevator shafts and water collection wells. [0003] In the excavation construction practice of earthwork...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a prefabricated caisson mold construction method in which silty soil can replace the brick tire formwork, which solves the problem of complete excavation of elevator shafts and water collection wells in the construction practice of silty soil earthwork excavation. Finally, when the gasket layer and the masonry brick tire formwork are not available in the future, landslides are prone to occur, causing great safety hazards, and the construction is difficult. Usually, elevator shafts and water collection shafts need to be supported by piles, but the construction period is too long , the cost is too high, and the construction is too difficult
