Combined snowflake type pile foundation construction system and construction method

Abstract

The invention discloses a combined snowflake type pile foundation construction system and a construction method. The pile foundation construction system comprises a combined snowflake type pile foundation and construction equipment, wherein the combined snowflake type pile foundation comprises a snowflake type concrete steel sheet pile and a powder spraying pile; the snowflake type concrete steel sheet pile is pressed into the powder spraying pile under the action of the construction equipment; the construction equipment comprises a base and an operation device; the operation device comprises a plurality of positioning locking devices, a manual operation system, a two-dimensional code remote operation system, a computer remote operation system and an operation system control center; the positioning locking devices are used for positioning the snowflake type concrete steel sheet pile; and the operation system control center is used for converting the manual operation system, the two-dimensional code remote operation system and the computer remote operation system so as to control the locking sizes of the positioning locking devices and the height of the construction equipment. According to the combined snowflake type pile foundation construction system and the construction method, the perpendicularity of a pile body is guaranteed when the snowflake type concrete steel sheet pile is sunk into the powder spraying pile, and the horizontal ultimate bearing capacity of the combined snowflake type pile foundation is improved.

Description

technical field [0001] The invention relates to a combined pile foundation in the fields of construction, rock and soil and geological engineering soft soil reinforcement, in particular to a combined snowflake-type pile foundation construction system and construction method. Background technique [0002] In geological engineering, different foundation reinforcement methods should be adopted according to different geological conditions. For example, there are large areas and deep liquefied soil layers and collapsible soil layers in the western and northwestern regions, and there are some muddy soft soils in the southern region. The high compressibility of the soft soil foundation will cause large unevenness in the building. Settling or even cracking and damage. [0003] In high embankments, ports, foundation pits and slope support projects of highways, the pile foundation is not only subjected to vertical loads, but also to large horizontal loads. Under the wind load and ear...

Problems solved by technology

[0006] Purpose of the invention: The purpose of the present invention is to provide a combined snowflake-type pile foundation construction system and construction method to solve the problem of uneven consolidation of the powder-sprayed pile body in the prior art when the pile body is pressed into the powder-sprayed pile The reason why the verticality of the pile body cannot be guaranteed due to the fact that the pile passes through different soil layers, and the lack of auxiliary devices leads to technical problems that reduce the construction quality
