Basement construction method and plug type bearing platform structure

Abstract

The invention relates to a basement construction method and a plug type bearing platform structure. The basement construction method is characterized by comprising the following steps of: (1) first, digging out basement earth to avoid the damage of the pile quality caused by digging out the earth after a pile is driven; (2) pouring a reinforced concrete bottom plate and leaving a room for the bearing platform; meanwhile, pouring an annularly closed girth on the bearing platform position; (3) driving a precast pile into the ground at the reserved bearing platform position; and (4) checking and accepting the precast pile; and if the precast pile is standard, pouring the plug type bearing platform structure at the bearing platform position and connecting the basement bottom plate to form a whole body; and if the precast pile is not standard, first repairing the pile, and then pouring the plug type bearing platform structure at the bearing platform position and connecting the basement bottom plate to form a whole body. The basement construction method and the plug type bearing platform structure, provided by the invention, are important construction process creation, which makes it possible that the basement construction sequence is changed from digging out the earth after the pile is driven into driving the pile after the earth is dug out; therefore, the construction quality accidents like pile inclination and pile body breakage in the soft foundation soil are avoided; and the time limit is shortened and the construction costs are reduced while the construction quality is improved.

Description

technical field [0001] The invention relates to a basement construction method and a plug-shaped platform structure thereof, which are suitable for basement floor structure construction. Background technique [0002] At present, in the basement construction procedure of soft foundation soil, what generally adopt is the construction procedure of excavating earthwork after piling first. Due to the heavy weight of the piling equipment, and the transportation of the piling equipment and the pile body, the stacking of the pile body and the construction work, etc., the site is required to have a strong bearing capacity, but the bearing capacity of the soft ground soil is low, and it is usually necessary to use the soft ground soil Reinforcement is carried out, such as filling a layer of dregs (sand) with high bearing capacity, replacing foundation soil, or changing the properties of soft foundation soil by adding cement and mixing. However, the above-mentioned methods all need to...

Problems solved by technology

However, adopting the above-mentioned methods all need to prolong the construction period and increase the cost

In addition, even if the above measures are taken to make the soft foundation soil meet the requirements of piling, during the excavation of the basement after piling, due to the dynamic action of the excavating machine, the pile in the soft foundation soil will often be tilted, and even the pile body will be damaged. broken quality accident
