The warp and weft type foundation pit supporting structure comprises a plurality of row piles arranged in a foundation pit, auxiliary cables and main cables for applying prestress, wherein the row piles include main piles and auxiliary piles, the main piles and the auxiliary are distributed in an I-shaped manner, a plurality of auxiliary piles are distributed between every two adjacent main piles, the auxiliary piles and the outer walls of the main piles are arranged on the same plane, the main piles and the auxiliary piles are connected with the auxiliary cables in a warp and weft weaving manner, one main cable is connected between every two adjacent main piles, and the main cable contacts with the outer walls of the auxiliary piles between the main piles. Compared with the prior art, the warp and weft type foundation pit supporting structure has the advantages that the lateral rigidity of the overall row piles is fully utilized, the normal (relative to the wall of the foundation pit) deformation of the row piles is resisted through cable force transmission, the diameters and embedding depths of the row piles are reduced, the integrity and stability of the foundation pit support structure are increased, underground space is saved greatly, and the structure is promising in application market and development prospects.
Description
Technical field
The present invention relates to Geotechnical Engineering field, particularly a kind of longitude and latitude foundation pit supporting construction.
Background technology
Existing pattern foundation pit supporting structure generally uses the method that campshed adds anchor cable, achieves preferable supporting effect.But, there is following subject matter in the method:
1. the underground space shared by anchor cable is relatively big, and a large amount of along with the underground space develop (such as subway, pipeline etc.), it is impossible to the foundation ditch meeting anchor cable construction space requirement gets more and more；
2., for being uniformly arranged the campshed of reinforcing bar, it is identical around pile body all directions rigidity.Existing supporting construction only make use of campshed normal direction (relative to foundation pit walls) rigidity, and lateral rigidity is not utilized effectively；
3. many foundation pit accident show, during instability of foundation pit, only part stake was lost efficacy.Now, if campshed being divided into unstability stake, being involved stake and anchor spike three part, Guan Liang and waist rail are delivered to, by involving the power of stake still based on normal direction (relative to foundation ditch) power, be unfavorable for that foundation ditch is stable；And anchor spike for unstability stake and is involved stake and can not play restriction and act on, and wastes the drag of part supporting construction.
Summary of the invention
The invention aims to solve the deficiency of prior art problem, a kind of longitude and latitude foundation pit supporting construction is provided, with campshed for " warp ", hawser is " latitude ", weaving, make full use of all directions rigidity of campshed self, improve supporting construction globality and stability and greatly saved the underground space.
For reaching above-mentioned purpose, the present invention implements according to techniques below scheme:
A kind of longitude and latitude foundation pit supporting construction, including the some campsheds being arranged in foundation ditch, also include secondary cable and the main push-towing rope of Shi Hanzhang, described campshed is made up of king pile and secondary stake, king pile and secondary stake are yi word pattern distribution, some secondary stake is distributed between every two adjacent king piles, the outer wall of secondary stake and king pile is arranged at grade, described king pile and secondary stake with pair cable to be connected in the way of knitting device, being respectively connected with main push-towing rope between two adjacent king piles, between described main push-towing rope with adjacent two king piles, the outer wall of secondary stake contacts.
Preferably, the two ends of described main push-towing rope cuff respectively is on two adjacent king piles.
Preferably, described king pile and secondary stake are cylinder, and the diameter of described king pile is more than the diameter of secondary stake.
Work process and the principle of the present invention be:
Fully mutually utilize the lateral rigidity of every single pile, make single pile be connected as entirety, when wherein part stake will be occurred unstability by bigger soil pressure:
1. king pile or the secondary stake of possible unstability will be suffered restraints by secondary cable a plurality of on it and keep stable, and the restraining forces of secondary cable is from all stable king piles and secondary stake；
The main push-towing rope of the most a plurality of Shi Hanzhang can provide the normal force being perpendicular to foundation pit walls, stops campshed unstability；This normal force is collectively constituted by the restraining forces of main push-towing rope prestressing force, king pile lateral rigidity and pressure secondary cable thereon.
Compared with prior art, beneficial effects of the present invention is as follows:
1. fully mutually utilize pile body lateral rigidity, reduce campshed stake footpath and insert depth；
2. improve globality and the stability of supporting construction；
The most ingenious utilization was not lost efficacy a rigidity, improved the drag of supporting construction；
The most greatly save the underground space.
Therefore, the present invention has wide application market and developing prospect.
