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.
Description
Technical field

Background technology
In recent years, along with the rise of highrise building, the scale of base pit engineering is also increasing.Meanwhile, the continuous construction of the fast development of underground traffic and underground store and urban operating mechanism, simply put slope excavation and can not meet engineering reality, the thing followed is the appearance of various space enclosing structure form.In base pit engineering, the problem of core is the appropriate design of retaining design the most, and this system should play the effect of gear soil, prevents the outer soil erosion of foundation ditch again, to make around foundation ditch surface settlement and control of horizontal displacement within permissible range.Adopt prefabricated sheet pile more in current engineering and carry out pattern foundation pit supporting structure, owing to will consider the retaining soil and water effect of supporting and protection structure, therefore pilespacing is arranged less, and materials'use amount is large, and single lifting lifting capacity is heavier, and mechanical instructions for use is high.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of and makes full use of support rigidity, strengthens base pit stability, the sheet pile supporting and protection structure 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 sheet pile supporting and protection structure with water stopping function, for the gear soil sealing of foundation ditch perisporium, comprise along the spaced sheet pile of pattern foundation pit supporting structure position line, described sheet pile two sides all have groove, the concrete attachment strap for keeping off native sealing is provided with between the groove of adjacent sheet pile, the two ends of concrete attachment strap embed in described groove, and concrete attachment strap two ends and groove junction are provided with the rubber fastening band for waterproof.
Preferably, described groove is square ribbon.
Preferably, it is 50% ~ 80% of foundation depth that described sheet pile stretches into the foundation ditch bottom solum degree of depth.
It is 10% of foundation depth that described rubber fastening band stretches into the foundation ditch bottom solum degree of depth.
Use the above-mentioned sheet pile supporting and protection structure with water stopping function to carry out a construction method for pattern foundation pit supporting structure, there are following steps:
A, according to Foundation Pit Support Design parameter, prefabricated or purchase sheet pile, concrete attachment strap;
B, be embedded in rubber fastening band at the groove of sheet pile;
C, along pattern foundation pit supporting structure position line, adopt three axes agitating pile grooving;
D, to be located by guide groove, insert sheet pile successively;
The groove location of e, aligning sheet pile, inserts concrete attachment strap;
F, repeat above-mentioned b-e step, sheet pile and concrete attachment strap are constantly linked together, enclose the sheet pile supporting and protection structure being formed and there is water stopping function.
The invention has the beneficial effects as follows: the present invention adopts fabricated construction, convenient and swift, there is stronger engineering practicability, concrete attachment strap plays the effect of retaining soil and water, and rubber fastening band plays waterproof sealing effect, and can suitably strengthen sheet pile spacing, make full use of the rigidity of supporting and protection structure, ensure the globality of supporting and protection structure, effectively improve the security and stability of base pit engineering, be particularly useful for the medium and small base pit engineering of rule relatively.

Detailed description of the invention
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of sheet pile supporting and protection structure with water stopping function as shown in Figure 1 and Figure 2, the gear soil sealing of foundation ditch 5 perisporium of 10m is less than or equal to for effective depth, comprise along the spaced sheet pile 1 of foundation ditch 5 supporting position line, described sheet pile 1 two sides all have square ribbon groove 2, the concrete attachment strap 3 for keeping off native sealing is provided with between the groove 2 of adjacent sheet pile 1, the two ends of concrete attachment strap 3 embed in described groove 2, and concrete attachment strap 3 two ends and groove 2 junction are provided with the rubber fastening band 4 for waterproof.
Wherein sheet pile 1 stretches into the foundation ditch 5 bottom solum degree of depth is 80% of foundation ditch 5 degree of depth; It is 10% of foundation ditch 5 degree of depth that rubber fastening band 4 stretches into the foundation ditch 5 bottom solum degree of depth.
Adopt the above-mentioned sheet pile supporting and protection structure with water stopping function to implement a construction method for pattern foundation pit supporting structure, there are following steps:
A, according to foundation ditch 5 support parameters, prefabricated or purchase sheet pile 1, concrete attachment strap 3;
B, along sheet pile 1 groove 2 internal perisporium embed rubber fastening band 4;
