Abstract

The utility model discloses a seamless junction underground diaphragm wall guide wall structure on a complex stratum. The seamless junction underground diaphragm wall guide wall structure on the complex stratum comprises holes I formed through a percussion drill and holes II formed through a rotary drilling multi-head drill or a guide plate grab machine, wherein the holes I and the holes II are arranged alternatively, the diameter of each hole I is larger than that of each hole II, the holes I are tangent with the holes II, and the thickness of a guide wall is smaller than the diameter of each hole II. The seamless junction underground diaphragm wall guide wall structure on the complex stratum has the advantages that the seamless junction underground diaphragm wall guide wall structure is good in permeability resistance, small in vibration and small in noise in construction process and quite suitable for city construction; a wall body is high in rigidity and capable of bearing large soil pressure used for excavation of a foundation pit, so that the accidents of foundation settlement or collapse hardly occur; construction can be carried out close to an original building; the seamless junction underground diaphragm wall guide wall structure can be applied to multiple stratum conditions, and is high in work efficiency, short in work period, reliable in quality and high in economic benefit.

Description

Bad ground seamless link underground impervious wall is led wall construction
Technical field
The utility model relates to the fields such as building, water conservancy, municipal administration, petroleum refining and nuclear industry, is that a kind of seamless link underground impervious wall that is applicable to bad ground is led wall construction specifically.
Background technology
TRD engineering method is the cutting box in insertion ground to be connected with main frame and transverse shifting, by the cutter digging ground on chain, inject simultaneously consolidation liquid in the vertical direction with original position soil mix and blend, in the engineering method of the firming body of underground formation wall shape.Underground impervious wall construction vibrations are little, noise is low, and wall stiffness is large, and barrier performance is good, to ground undisturbed around, can form and have the very arbitrary polygon diaphragm wall of large bearing capacity and replace pile foundation, open caisson foundation or laying foundation.In when construction, but in the time of bad ground construction, when TRD equipment cannot cut and need to set in advance and lead wall construction, otherwise, cannot cut into wall for the TRD equipment of constructing.Therefore, how to arrange and lead wall construction and become the necessary condition that affects TRD equipment construction.
Utility model content
For solving the problems of the technologies described above, the object of this invention is to provide a kind of bad ground seamless link underground impervious wall and lead wall construction, comprise and adopt the hole one of Churn drill formation and the hole two of rotary cutting Multi-drill bit or the formation of guide plate grab claw, the setting alternate with hole two of described hole one, the diameter in hole one is greater than the diameter in hole two; Hole one and hole two are tangent, lead the diameter that wall thickness is less than hole two.
Hole one diameter is 1000mm; Hole two diameters are 800mm; Leading wall thickness is 600mm.
The utility model has the advantages that: 1. impervious good; 2. when construction in, is shaken littlely, and noise is low, is highly suitable for municipal construction; 3. wall stiffness is large, during for excavation of foundation pit, can bear very large soil pressure, and foundation settlement or cave in accident seldom occur; 4. can press close to inhering architecture construction; 5. be applicable to multiple formation condition; 6. work efficiency is high, the duration is short, reliable in quality, economic benefit are high.
Brief description of the drawings
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Illustrate the utility model below in conjunction with accompanying drawing, as shown in Figure 1, the utility model comprises the hole 1 of employing Churn drill formation and the hole 22 of rotary cutting Multi-drill bit or the formation of guide plate grab claw, the setting alternate with hole 22 of described hole 1, and the diameter in hole 1 is greater than the diameter in hole 22; Hole 1 and hole 22 are tangent, lead the diameter that wall 3 thickness are less than hole 22.
Hole one 1 diameters are 1000mm; Hole 22 diameters are 800mm; Leading wall 3 thickness is 600mm.
Principle of the present utility model is: first adopt Churn drill to hole to bad ground, and because the boring procedure of Churn drill must carry out sharp pounding to harder lithosphere, therefore, very favourable to adopting rotary cutting Multi-drill bit or guide plate grab claw to form hole; Through after two kinds of pore-formings above, TRD construction equipment can cut into wall easily, finally forms impervious wall.
