Abstract
The invention discloses a building foundation construction method, in particular to a subsequent anchor cable secondary grouting construction method in a building foundation construction. The method includes the following steps: using a drill to drive the anchor rib and the grouting pipe of the anchor cable into a designed depth for one time simultaneously when drilling in; then grouting a solidifying liquid in a bore through the grouting pipe; taking a drill stem out and leaving the anchor bar and the grouting pipe initial setting of the solidifying liquid. Compared with the prior art, the invention solves the problem of no bore-forming in a sand layer anchor rod construction and leads the bore-forming and grouting to be finished for one time, solves the secondary grouting problem in the construction and reduces the construction cost. The method greatly reduces the construction cost of the anchor rod or the anchor cable in the sand layer and improves the construction speed. The cost is reduced by 30 percent and the efficiency is improved by 50 percent.
Description
Technical field
The present invention relates to a kind of construction foundation working method, particularly relate to the follow type anchor wire secondary slip casting construction method in a kind of construction foundation working.
Background technology
In the existing deep foundation pit support engineering, anchoring construction is used two kinds of methods always.A kind of is the anchor bolt construction method, and another kind is the anchor cable construction method.The former has, and construction is simple, the reliable advantage of anchoring.But its cost is higher.The anchor cable construction method because of its construction cost is low than the former, is progressively approved by market when having the supremacy clause that construction technology is easy, the Device-General formula is good.But some problems are also arranged in engineering is finished, mainly show as: when loose sandy soil layer carried out anchor cable construction, because the pore-forming difficulty, slip casting effect was undesirable, and stretching resistance is low.Cause the anchor cable operating efficiency to reduce, construction cost increases.
Summary of the invention
It is to have solved pore-forming difficult problem in the anchor cable construction that the present invention provides a kind of follow type anchor wire secondary slip casting construction method, purpose in order to solve the problems of the technologies described above exactly, has also solved the low problem of anchor cable uplift resistance simultaneously.
In order to solve the problems of the technologies described above, the present invention is achieved in that a kind of follow type anchor wire secondary slip casting construction method, and it comprises following processing step: use rig dowel and disposable designated depth of bringing into of Grouting Pipe with anchor cable when creeping into; Then by Grouting Pipe perfusion consolidation liquid in boring; Propose drilling rod and dowel and Grouting Pipe are stayed in the hole; Before the consolidation liquid initial set, carry out secondary grouting by Grouting Pipe.
Described anchor cable is substituted by anchor pole.
Described secondary grouting pressure generally be controlled at 0.5-2.5mpa between.
The described secondary grouting time is to carry out after 2-4 hour after the slip casting for the first time.
Advantage of the present invention and effect are as follows:
1, compares than conventional art and solved in the layer of sand anchor bolt construction the not problem of pore-forming, pore-forming slip casting is once finished.
2, solved the problem of secondary grouting in the construction.Secondary grouting pressure generally be controlled at 0.5-2.5mpa between
3, reduced construction cost, the method greatly reduces the cost that anchor pole or anchor cable are constructed in layer of sand, improved speed of application.Cost reduces by 30%, and efficient improves 50%
Through evidence job practices of the present invention is rationally advanced and actual effective good method, and it had both solved pore-forming difficult problem in the anchor cable construction, had also solved the low problem of anchor cable uplift resistance simultaneously.
The specific embodiment
Below description by the specific embodiment the present invention is described in further detail, but this can not be used for limitation of the present invention, those skilled in the art are according to basic thought of the present invention, can make various modifications or improvement, but only otherwise break away from basic thought of the present invention, all within the scope of the present invention.
A kind of follow type anchor wire secondary slip casting construction method of the present invention: use rig dowel and disposable designated depth of bringing into of Grouting Pipe with anchor cable when creeping into; Then by Grouting Pipe perfusion consolidation liquid in boring; Propose drilling rod and dowel and Grouting Pipe are stayed in the hole; Before the consolidation liquid initial set, carry out secondary grouting by Grouting Pipe.Wherein secondary grouting pressure generally be controlled at 0.5-2.5mpa between.The described secondary grouting time is to carry out after 2-4 hour after the slip casting for the first time.
Used anchor pole or anchor cable can be selected any one disclosed product now for use.
Claims (4)
1, a kind of follow type anchor wire secondary slip casting construction method is characterized in that it comprises following processing step: use rig dowel and disposable designated depth of bringing into of Grouting Pipe with anchor cable when creeping into; Then by Grouting Pipe perfusion consolidation liquid in boring; Propose drilling rod and dowel and Grouting Pipe are stayed in the hole; Before the consolidation liquid initial set, carry out secondary grouting by Grouting Pipe.
2, follow type anchor wire secondary slip casting construction method according to claim 1 is characterized in that described anchor cable is substituted by anchor pole.
3, follow type anchor wire secondary slip casting construction method according to claim 1, it is characterized in that described secondary grouting pressure generally be controlled at 0.5-2.5mpa between.
4,, it is characterized in that carrying out after 2-4 hour after the described secondary grouting time is for slip casting for the first time according to claim 1 or 3 described follow type anchor wire secondary slip casting construction methods.
