Embodiment 1

[0063] Embodiment 1 of the present application discloses an efficient multi-equipment construction method for carrier piles. refer to figure 1 and figure 2 , the carrier pile includes a concrete pile body 101, a pull-out steel bar 102, a filler material 103, an impact soil mass 104, a compacted soil mass 105, a cap 109 and a raft 110, and the cap 109 and the raft 110 are arranged on the concrete pile body At the top of the pile 101, the top of the rod portion of the pull-out steel bar 102 extends upwards into the cap 109 and the raft 110, and the filling material 103 is a mixture of cement and sand. In other embodiments, the filling material 103 can also be dry hard concrete. The compacted soil 105 is formed by mixing and compacting the cement-sand mixture and the undisturbed soil, and the affected soil 104 is the undisturbed soil that has been rammed at the bottom of the pile hole. The length of the bottom of the pullout steel bar 102 hammered into the carrier is 80 cm. In...

Embodiment 2

[0086] Embodiment 2 of the present application discloses a multi-equipment efficient construction method for carrier piles, combining figure 2 and Figure 8 , the difference from Embodiment 1 is that in step S8, the following steps are included:

[0087] Installation of prefabricated piles S83: prefabricating multiple steel cages 11 and concrete to form prefabricated piles 12 (see Figure 9 ), hoist the prefabricated pile 12 and put it into the steel casing 106, the center of the prefabricated pile 12 forms a pipe pile hole for accommodating the rod of the pull-resistant steel bar 102, and penetrates the rod of the pull-resistant steel bar 102 into the prefabricated pile 12, measure the elevation of the prefabricated pile 12 and adjust the prefabricated pile 12 within the allowable error range;

[0088] Pouring cement mortar or concrete S84: pouring cement mortar or concrete in the prefabricated pile 12, measuring and controlling the elevation of the pouring cement mortar. ...

Embodiment 3

[0091] Embodiment 3 of the present application discloses a multi-equipment efficient construction method for carrier piles, combining figure 2 and Figure 10 , and the difference from Embodiment 1 is that the top end of the rod portion of the pull-out steel bar 102 does not extend into the platform 109 and the raft 110, and the length of the rod portion of the pull-out steel bar 102 is roughly half the length of the carrier pile.

Abstract

This application relates to a carrier pile multi-equipment efficient construction method, and relates to the technical field of carrier pile construction. The carrier pile includes a concrete pile body, pull-out steel bars, fillers, impacted soil, and compacted soil. The construction method includes the following constructions Steps: When the equipment enters the site, prepare cranes, vibratory hammers, hydraulic clamps, multiple steel casings, multiple solid column hammer pile drivers and multiple hollow column hammer pile drivers at the construction site, and install the vibratory hammer on the crane. Set pouring port on the hook and on the steel casing; measure the line and sink the steel casing; form a hole; tamp the filling material; measure the three-strike penetration; lower the pull-out steel bar; tamp the filling material with the hollow column hammer; form Concrete pile body; pull out sleeve. The application has the effects of low equipment investment cost, high equipment utilization rate and high construction efficiency.

Description

technical field [0001] The present application relates to the technical field of carrier pile construction, in particular to an efficient multi-equipment construction method for carrier piles. Background technique [0002] The carrier pile is a kind of pile different from the ordinary sense. The carrier pile is mainly composed of two parts: the upper pile body and the lower "composite carrier". The pile body is generally a cast-in-place concrete structure or a high-strength prestressed prefabricated pile. The composite body located at the bottom of the pile body and compacted by deep filling materials uses the free fall movement of the heavy hammer to repeatedly tamp and compact the deep soil at the pile tip, so that the soil within a certain range below the pile tip can be most effectively Ground reinforcement and compaction to form a "composite carrier" is the technical core of this type of pile, which can diffuse and reduce the stress at the pile tip layer by layer, chang...
