Abstract
The invention discloses a sheet pile supporting structure with a water stopping function and a construction method. The sheet pile supporting structure with the water stopping function and the construction method are used for soil blocking and water stopping of the circumferential wall of a foundation pit. The sheet pile supporting structure with the water stopping function comprises sheet piles which are arranged along a positioning line for supporting of the foundation pit at intervals. Grooves are formed in the two side faces of each sheet pile respectively. A concrete splicing plate used for soil blocking and water stopping is arranged between the grooves of every two adjacent sheet piles. The two ends of each concrete splicing plate are embedded into the corresponding grooves. Rubber waterstops used for water prevention are arranged at the joints of the two ends of each concrete splicing plate and the corresponding grooves. According to the sheet pile supporting structure with the water stopping function and the construction method of the sheet pile supporting structure, assembly type construction is adopted, convenience and rapidness are achieved, the concrete splicing plates have the soil blocking and water stopping functions, and the rubber waterstops have the water preventing and sealing functions; the distance between the sheet piles can be properly increased, so that the pile insertion soil squeezing effect is relieved, the integrity of the supporting structure is guaranteed, the rigidity of the supporting structure is effectively improved, and finally the safety and stability of a foundation pit project are achieved; the sheet pile supporting structure is particularly suitable for relatively regular medium and small foundation pit projects.

Rigidity, enhancing base pit stability, the sheet pile supporting construction with water stopping function of good water-proof effect and construction method.
The technical solution adopted for the present invention to solve the technical problems is：A kind of knot of the sheet pile supporting with water stopping function
Structure, for the gear soil sealing of foundation ditch perisporium, including along the spaced sheet pile of pattern foundation pit supporting structure position line, described sheet pile two sides
Groove is respectively provided with, the concrete attachment strap for keeping off native sealing is provided between the groove of adjacent sheet pile, the two ends of concrete attachment strap are embedded in described recessed
In groove, concrete attachment strap two ends are provided with the rubber fastening band for waterproof with groove junction.
Preferably, described groove is square ribbon.
Preferably, described sheet pile stretches into 50%～80% that bottom of foundation ditch soil depth is foundation depth.
Described rubber fastening band stretches into 10% that bottom of foundation ditch soil depth is foundation depth.
A kind of construction method that pattern foundation pit supporting structure is carried out using the above-mentioned sheet pile supporting construction with water stopping function, with as follows
Step：
A, according to Foundation Pit Support Design parameter, it is prefabricated or purchase sheet pile, concrete attachment strap；
B, it is embedded in rubber fastening band in the groove of sheet pile；
C, along pattern foundation pit supporting structure position line, using three axes agitating pile grooving；
D, by guide groove position, be sequentially inserted into sheet pile；
The groove location of e, alignment sheet pile, inserts concrete attachment strap；
F, the above-mentioned b-e steps of repetition, sheet pile is constantly linked together with concrete attachment strap, encloses to be formed with water stopping function
Sheet pile supporting construction.
The invention has the beneficial effects as follows：The present invention adopts fabricated construction, convenient and swift, with stronger Practical
Property, concrete attachment strap plays a part of retaining soil and water, and rubber fastening band plays waterproof sealing effect, and can suitably increase sheet pile spacing,
Make full use of the rigidity of supporting construction, it is ensured that the globality of supporting construction, effectively improve the security and stability of base pit engineering, especially
Suitable for relatively regular medium and small base pit engineering.
