Description

A kind of longitude and latitude foundation pit supporting construction
Technical field
This utility model 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, the method There is following subject matter:
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 is 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 is divided into unstability stake, Being involved stake and anchor spike three part, Guan Liang and waist rail are delivered to the power by involving stake and with normal direction (relative to foundation ditch) power are still Main, it is 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, waste part The drag of protection structure.
Summary of the invention
The purpose of this utility model is intended to solve the deficiency of prior art problem, it is provided that a kind of longitude and latitude pattern foundation pit supporting structure knot Structure, with campshed for " warp ", hawser is " latitude ", weaving, makes full use of all directions rigidity of campshed self, improves supporting construction Globality and stability have also greatly saved the underground space.
For reaching above-mentioned purpose, this utility model is implemented 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 includes secondary cable and applying Prestressed main push-towing rope, described campshed is made up of king pile and secondary stake, and king pile and secondary stake are yi word pattern distribution, every two adjacent king piles Between some secondary stake be distributed, the outer wall of secondary stake and king pile is arranged at grade, described king pile and secondary stake with secondary cable with warp The mode of knitting device connects, and is respectively connected with main push-towing rope, between described main push-towing rope with adjacent two king piles between two adjacent 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 of the present utility model and principle be:
Fully mutually utilize the lateral rigidity of every single pile, make single pile be connected as entirety, when wherein part stake is subject to bigger Soil pressure when unstability will occur:
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, the constraint of secondary cable Power 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 method Collectively constitute by the restraining forces of main push-towing rope prestressing force, king pile lateral rigidity and pressure secondary cable thereon to power.
Compared with prior art, the beneficial effects of the utility model are 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, this utility model has wide application market and developing prospect.
