Construction equipment of hole drilling/punching cast-in-place pile with self-provided mud pit and mud separating device

Abstract

The invention discloses construction equipment of a hole drilling / punching cast-in-place pile with a self-provided mud pit and a mud separating device, which consists of the self-provided mud pit, the mud separating device, normal / reverse circulation drilling / punching drilling machine and a caterpillar pile driver platform, and adopts the construction method that the mud pit is arranged on the caterpillar pile driver platform, the drilling machine simultaneously drills and removes sediments through a sediment removing pipe, and the mud is absorbed into a screen mud conveyor through a mud pipe to be preliminarily separated with the bigger clay particles being separated out; the separated mud flows into a mud separating tank, and the sediments sink into the extrusion mud separator to be removed; the liquid mud flows into the self-provided mud pit of the pile driver through a mud overflow hole and is injected into the pile hole for cyclic utilization through a mud flowrate control valve. The invention has the advantages that the mud pit is not required to be excavated on the construction site, so as to avoid the on-site mud contamination; the mud is filtered layer by layer with the clay particles and sediments being separated out for cyclic utilization; the mud concentration is controllable, the hole is regularly formed, and the hole forming is quick in speed; and the rock embedding performance is high, the bearing capability is high after the pile is driven, and the pile foundation is low in cost.

Description

technical field [0001] The invention relates to a construction equipment and a construction method for drilling / punching cast-in-place piles with its own mud pool and mud separation device, and belongs to the technical field of building construction. Background technique [0002] With the development of the national economy, all kinds of civil and industrial buildings are increasingly high-rise, and cast-in-place piles have been recognized by many design units and construction units for their unique advantages of large bearing capacity. It is indeed an affordable form of foundation. [0003] Affected by factors such as building structure type, load distribution, geological conditions, construction equipment and construction conditions, the choice of pile type is greatly limited, especially when encountering high groundwater levels such as silt or silt soil or quicksand layers. In the case of unfavorable geological conditions, according to the current dry and wet methods of ...
