Embodiment Construction

[0046] The following is attached Figure 1-4 The application is described in further detail.

[0047] The embodiment of the present application discloses a construction method for pre-mixed fluid solidified soil foundation treatment. refer to figure 1 , the ready-mixed fluid solidified soil foundation treatment construction method comprises the following steps:

[0048] S1. Plane laying out of the foundation treatment area. The surveyors arrange the positioning control piles, elevation level piles and the gray line size of the groove at the foundation treatment position according to the plane control network of the site and the foundation treatment construction plan. Elevation control lines are set on the outer wall of the completed structure or on the surface of the formwork to strictly control the pouring elevation and flatness.

[0049] S2. Natural foundation cleaning, excavation treatment of the natural foundation with too weak bearing capacity.

[0050] S3. Support fo...

Abstract

The invention discloses a premixed flow state solidified soil foundation treatment construction method. The premixed flow state solidified soil foundation treatment construction method comprises the following steps of S1, plane paying-off being conducted in a foundation treatment area; S2, cleaning a natural foundation; S3, erecting a template and a working platform; S4, cleaning a pouring area and protecting a finished product; S5, pouring, wherein in the pouring process, homogenizing auxiliary equipment is used for homogenizing; and S6, maintenance being conducted. The homogenizing auxiliary equipment comprises a chassis and a support arm, an end part of the support arm is provided with a sun gear, a plurality of planetary gears and a gear ring, and the planetary gears are simultaneously engaged with the sun gear and the gear ring; a main stirring rod is coaxially and fixedly connected to a lower end of the sun gear, an auxiliary stirring rod is coaxially and fixedly connected to a lower end of the planetary gear, disturbance blades are arranged on the main stirring rod, and a power device used for driving the disturbance blades to do reciprocating lifting motion and rotate on the main stirring rod is arranged between the main stirring rod and the auxiliary stirring rod. The method is advantaged in that the homogenizing effect of the flow-state solidified soil in the pouring process is good, construction efficiency is high, and the forming quality is good.

Description

technical field [0001] The present application relates to the field of foundation treatment, in particular to a construction method for ready-mixed fluid solidified soil foundation treatment. Background technique [0002] Ready-mixed liquid solidified soil is a new type of building material. It makes full use of the excavated fertilizer tank, foundation pit or abandoned foundation soil. After mixing a certain proportion of solidifying agent and water, it is fully mixed to form a The pumpable and fluid reinforcement material is used for backfilling of various fertilizer tanks, foundation pits, and mine pits, and can also be widely used in reinforcement treatment fields such as road subgrades and building foundations. [0003] Due to the good fluidity of the fluid solidified soil after mixing, inhomogeneity is prone to occur during the pouring process, especially in parts of the structure that are subject to greater stress, such as column bases, wall corners, and load-bearing ...
