The continuous steel sheet pile that is used for pattern foundation pit supporting structure or diaphragm wall
Technical field
The utility model relates to technical field of building construction, is specifically related to a kind of continuous steel sheet pile that is used for pattern foundation pit supporting structure or diaphragm wall.
Background technology
Steel sheet pile is usually used in sealing in pattern foundation pit supporting structure or the construction of diaphragm wall and bank protection (common have U type, T type, V-type, Z type etc.), has quick construction, safety, environmental protection, characteristics attractive in appearance, and is very extensive in sector applications such as traffic, water conservancy, municipal administrations.Earlier steel sheet pile is squeezed into the precalculated position in the construction, construction finishes and again steel sheet pile is extracted recycling.In the work progress, the mode of closing, fastening by tenon between the two adjacent steel sheet piles connects.The watertightness of this type of steel sheet pile is relatively poor, uses after a period of time, and the easy corrosion of steel sheet pile influences the dismounting and the sealing performance of steel sheet pile, often need handle the situation of leaking in the sealing construction; And along with the increase highly of retaining soil, single steel sheet pile is crushed out of shape or deviation post easily, influences normal construction.
Background technology
The purpose of this utility model is the deficiency that overcomes in the above-mentioned background technology, and a kind of continuous steel sheet pile that is used for pattern foundation pit supporting structure or diaphragm wall is provided, and that this continuous steel sheet pile should have is simple in structure, easy construction, good airproof performance, on-deformable characteristics.
For realizing above purpose, the utility model has adopted following technical scheme:
The continuous steel sheet pile that is used for pattern foundation pit supporting structure or diaphragm wall is made up of first shaped steel sheet pile and the B-mode steel sheet pile that arrange several spaces, and adjacent first shaped steel sheet pile and B-mode steel sheet pile are locked mutually; It is characterized in that: the edge, the left and right sides of described first shaped steel sheet pile respectively is fixed with a steel bushing of vertically arranging, the right flank of the left surface of left side steel bushing, right side steel bushing respectively offers a fluting that vertically stretches; The edge, the left and right sides of described B-mode steel sheet pile respectively is fixed with a Grouting Pipe that is used for the pressure injection cement paste, and this Grouting Pipe is vertically inserted in the described steel bushing and with it and is complementary; The plate body thickness of the width of described fluting and B-mode steel sheet pile is complementary.
The tube wall of described Grouting Pipe is shaped on some injected holes, and the bottom of Grouting Pipe is fixed with the retaining mud capping.
The plate of described first shaped steel sheet pile and B-mode steel sheet pile respectively is shaped at least one anchor pole reinforced hole on one's body.
The plate body of described first shaped steel sheet pile, B-mode steel sheet pile and described Grouting Pipe, steel bushing all adopt the thick galvanized steel plain sheet of 5-15mm to make.
Use principle of the present utility model is: in the work progress, can earlier first shaped steel sheet pile be driven underground, be driven underground behind the steel bushing with the aligning of the Grouting Pipe on the left of B-mode steel sheet pile first shaped steel sheet pile right side again by (steel bushing that the Grouting Pipe on perhaps B-mode steel plate right side is aimed at first shaped steel cover left side), the operation of driving piles in regular turn afterwards makes first shaped steel sheet pile and B-mode steel sheet pile space arrange and form continuous steel sheet-pile wall.After finishing, piling can improve the supporting capacity of steel sheet pile after cement paste or mortar solidify by Grouting Pipe to steel sheet pile bottom pressure injection cement paste or mortar.
The beneficial effects of the utility model are: the utility model cooperates by steel bushing and Grouting Pipe, makes first shaped steel sheet pile and B-mode steel sheet pile lock securely, and is simple in structure, easy to use; And after piling is finished, can promote the supporting capacity of steel sheet pile on the one hand by Grouting Pipe toward steel sheet pile bottom pressure injection cement paste or mortar, cement paste can fill up the gap between Grouting Pipe and the steel bushing on the other hand, strengthens the watertightness of steel sheet pile.In addition, the utility model also can by plate on one's body the anchor hole skyhook or anchor cable to resist the pressure of native side, make steel sheet pile not yielding or the displacement.

The specific embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
Embodiment 1
As shown in Figure 1, the continuous steel sheet pile that is used for pattern foundation pit supporting structure or diaphragm wall described in the utility model, first shaped steel sheet pile 1 and the B-mode steel sheet pile of being arranged by several spaces 2 forms that (described first shaped steel sheet pile and B-mode steel sheet pile are the stake of T template, buyable obtains), adjacent first shaped steel sheet pile and B-mode steel sheet pile are locked mutually.The edge, the left and right sides of described first shaped steel sheet pile respectively is fixed with a steel bushing 1-1 who vertically arranges (as shown in Figure 2, the cross section of this steel bushing is rectangular, also can make other shapes as required), the right flank of the left surface of left side steel bushing, right side steel bushing respectively offers a fluting 1-2 who vertically stretches; For making things convenient for the connection between each steel sheet pile, this fluting is positioned at the position of center line of described left side steel bushing left surface and the position of center line of right side steel bushing right flank.The edge, the left and right sides of described B-mode steel sheet pile respectively is fixed with a Grouting Pipe 2-1 who is used for the pressure injection cement paste, and this Grouting Pipe is vertically inserted in the described steel bushing and with it and is complementary.The plate body thickness of the width of described fluting and B-mode steel sheet pile is complementary, and the plate body of B-mode steel sheet pile inserts in this fluting.
As shown in Figure 7, the tube wall of described Grouting Pipe is shaped on some injected hole 2-11, in order to make the bottom of mud pressure injection at steel sheet pile, described steel bushing and first shaped steel sheet pile and B-mode steel sheet pile certain distance (specifically determining according to actual conditions) are stretched out in the lower end of described Grouting Pipe; Simultaneously, the bottom of Grouting Pipe is fixed with retaining mud capping 2-12 to prevent that earth stops up Grouting Pipe in the piling process.After slip casting was finished, curing area 4 can be formed on the steel sheet pile bottom, strengthened the supporting capacity of steel sheet pile.In addition, also can reinforce continuous steel sheet pile at the welded top shaped steel or the concreting of continuous steel sheet pile.
As shown in Figure 8, in order to resist earth lateral pressure, prevent that steel plate is crushed out of shape or is shifted, the plate of described first shaped steel sheet pile and B-mode steel sheet pile respectively is shaped at least one anchor pole reinforced hole 3 on one's body, can be during construction according to the anti-native degree of depth, select the anchor pole (or anchor cable) of different length to squeeze in the soil, steel sheet pile is reinforced from the anchor pole reinforced hole.Less than 4m, rock-bolt length is recommended between the 2-6m as the anti-native degree of depth.
The plate body of described first shaped steel sheet pile, B-mode steel sheet pile and described Grouting Pipe, steel bushing all adopt the thick galvanized steel plain sheet of 5-15mm to make.
Embodiment 2
Embodiment 2 is that with the difference of embodiment 1 first shaped steel sheet pile and B-mode steel sheet pile are V-type plate stake (outsourcing acquisition) among the embodiment 2, and remainder and method of attachment are all similar to Example 1, do not do detailed description at this.
