Abstract

The utility model relates to an underground continuous wall with arrangement of three round connective piles, which is characterized by being formed through assembly of the three round connective piles with the same structure, the three round piles of the three round connective piles have the same diameter and are connected into a whole in a tangential way, and adjacent round connective piles are also arranged in a tangential way. The utility model has the following advantages that: the bodies three round connective piles arranged to form the wall are connected into the whole, adjacent round connective piles are concreted, no pile clearance is formed, good anti-seepage effect can be achieved, and the wall is safe and reliable; while the wall maintain the same thickness as the conventional underground continuous wall with a single round pile, the amount of concrete can be saved by more than 30 percent; and holes can be formed rapidly, and the construction cycle of the formed piles and the formed wall can be shortened effectively.

Description

Three circle disjunctor row of piles formula diaphragm walls

Technical field

The utility model relates to a kind of three circle disjunctor row of piles formula diaphragm walls that are used for.

Background technology

Conventional row of piles formula diaphragm wall, its cross section is single circular, adopt borehole or drill-pouring steel concrete to form, owing to be single pile, do not link to each other mutually between the pile body, and there is certain clearance, this just must be after concrete reaches demarcation intensity, impose cement mixing pile or high-pressure rotary jet grouting pile again in the bonding crack position of two pile bodies to obtain anti-seepage effect, the shortcoming of this row of piles formula diaphragm wall be impossible facilitate the stake with between closely be connected, and the job practices of secondary caulking joint, the duration also is long, because the consolidation time of cement mixing pile is very long.

The utility model content

The purpose of this utility model just provides that a kind of speed of application is fast, three circle disjunctor row of piles formula diaphragm walls of good seepage-proof property.

The technical solution of the utility model is: a kind of three circle disjunctor row of piles formula diaphragm walls, it is spliced mutually by three identical circle disjunctor stakes of structure, three circular stake diameters of described three circle disjunctor stakes are identical, and three a circular disjunctor and tangent, and are also tangent between the three adjacent circle disjunctor stakes.

Of the present utility model three justify disjunctor row of piles formula diaphragm walls, compare with existing single circle row of piles formula diaphragm wall to have the following advantages:

L, be arranged in three circles of wall, pile body disjunctor not only, and and left and right sides adjacent studs close with fixed attention, do not have a gap, also need not apply cement mixing pile or high-pressure rotary jet grouting pile again, its good seepage-proof property, safety, reliably;

2, under the identical situation of the single circle of routine row of piles formula diaphragm wall design thickness of wall body, can economize concrete more than 30 percent;

But 3 fast pore-creatings can effectively shorten pile, become the wall construction period.

Description of drawings

Figure l is the utility model structural representation.

The specific embodiment

Embodiment is as shown in Figure 1: a kind of three circle disjunctor row of piles formula diaphragm walls, diaphragm wall is spliced mutually by three identical circle disjunctor stakes of structure, three circular stake l diameters of described three circle disjunctor stakes are identical, and three a circular l disjunctor and tangent, and are also tangent between the three adjacent circle disjunctor stakes.

Claims

1. plant three circle disjunctor row of piles formula diaphragm walls, it is characterized in that: diaphragm wall is spliced mutually by three identical circle disjunctor stakes of structure, three circular stake diameters of described three circle disjunctor stakes are identical, and three a circular disjunctor and tangent, and are also tangent between the three adjacent circle disjunctor stakes.
