Abstract

The utility model discloses a kind of bad ground seamless link underground impervious wall and leads wall construction, it is characterized in that: the hole two comprising hole one and rotary cutting Multi-drill bit or the guide plate grab claw formation adopting Churn drill to be formed, described hole one vertical ground, wall two side position of leading between described hole one arranges multiple hole two, and described hole two is longitudinally arranged in " y " type; " y " type of described hole two longitudinal direction is set to be symmetrical arranged.The utility model has the advantages that: 1. impervious good; 2. shake little during construction, 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, few generation foundation settlement or cave in accident; 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, high financial profit.

Description

Bad ground seamless link underground impervious wall leads 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 being applicable to bad ground leads wall construction specifically.
Background technology
TRD engineering method is that the cutting box inserted in ground is connected and transverse shifting with main frame, by the cutter digging ground on chain, injects the consolidation liquid native mix and blend with original position in the vertical direction simultaneously, forms the engineering method of the firming body of wall shape in underground.Underground impervious wall construction vibrations are little, noise is low, and wall stiffness is large, and barrier performance is good, to around ground undisturbed, can form the arbitrary polygon diaphragm wall with very large bearing capacity and replace pile foundation, open caisson foundation or laying foundation.When constructing, but when bad ground construction, need to pre-set when TRD equipment cannot cut and lead wall construction, otherwise the TRD equipment for constructing cannot carry out cutting into wall.Therefore, how to arrange and lead wall construction and become the necessary condition affecting TRD equipment construction.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of bad ground seamless link underground impervious wall and leads wall construction, comprise the hole two of hole one and rotary cutting Multi-drill bit or the guide plate grab claw formation adopting Churn drill to be formed, described hole one vertical ground, wall two side position of leading between described hole one arranges multiple hole two, and described hole two is longitudinally arranged in " y " type;
" y " type of described hole two longitudinal direction is set to be symmetrical arranged;
The described asymmetric setting in multiple holes two led wall two side position and arrange.
The utility model has the advantages that: 1. impervious good; 2. shake little during construction, 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, few generation foundation settlement or cave in accident; 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, high financial profit.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is vertical structure schematic diagram.
Detailed description of the invention
The utility model is illustrated below in conjunction with accompanying drawing, as shown in Figure 1 and Figure 2, the utility model comprises the hole 23 of hole 1 and rotary cutting Multi-drill bit or the guide plate grab claw formation adopting Churn drill to be formed, described hole 1 vertical ground, wall 1 liang of side position 11,12 of leading between described hole 1 arranges multiple hole 23, described hole two comprises two holes 3,31 that two longitudinal directions are tiltedly arranged, and the length of its mesopore 31 is less than hole 3, and hole 3 and hole 31 form " y " type;
" y " type of described hole two longitudinal direction is set to be symmetrical arranged;
As shown in Figure 1, the asymmetric setting in multiple holes 23 that wall 1 liang of side position 11,12 is arranged is led described in.
Hole 1 diameter is 1000mm; Hole 22 diameter is 200mm; Leading wall 3 thickness is 600mm.
Principle of the present utility model is: first adopt Churn drill to hole to bad ground, because the boring procedure of Churn drill must carry out sharp pounding to harder lithosphere, therefore, forms hole very favourable to employing rotary cutting Multi-drill bit or guide plate grab claw, in addition, reduce the drilling hole amount of leading wall construction as far as possible and can reduce engineering quantity, reduce costs, and large diameter hole is relative to the hole of minor diameter, construction cost is higher, for this reason, hole one quantity formed by Churn drill reduces, at two side positions of leading wall, the rotary cutting Multi-drill bit of minor diameter or the hole 23 of guide plate grab claw formation are set, and hole 23 is in " y " type, and setting can expand pretreatment area as far as possible, simultaneously, reduce drilling depth, reach and hard bad ground is decomposed, broken, meet TRD engineering method construction requirement, the more important thing is, decrease boring amount, finally form impervious wall with lower cost.
