The specific embodiment
As one embodiment of the present of invention, introduce slope retaining Composite Bolt structure construction, operating principle and the job practices of banketing of the present invention in conjunction with Fig. 1 to Fig. 6.At first combine Fig. 1, Fig. 6 to introduce the slope retaining Composite Bolt structure construction that bankets of the present invention.As shown in Figure 1; The slope retaining Composite Bolt of banketing comprises the load transfering strip that bankets (1); The anchor pole two parts that banket are formed; The load transfering strip that bankets (1) wherein directly contacts with banketing; The anchor pole that bankets is connected with the load transfering strip that bankets (1); The anchor pole that bankets comprises the body of rod (2) and anchoring body (3) two parts composition; The body of rod (2) is positioned at anchoring body (3); The load transfering strip that bankets (1) in Fig. 1 can be a concrete; It also can be mortar; It can also be cement paste; The shape of load transfering strip (1) of banketing can be a tubulose; Bar shaped; Or a blocks, the load transfering strip that bankets (1) can also be the combination of a plurality of blocks.The body of rod (2) can be a reinforcing bar, also can be steel strand, can also be tension members such as steel pipe.Anchoring body (3) can be materials such as cement mortar, cement paste, epoxy resin; Be positioned at anchoring body (3) in order to ensure the body of rod (2); Can between the anchoring body (3) and the body of rod (2), locator (4) be set; The available reinforcement fabrication of locator (4), locator (4) can guarantee that the body of rod (2) has enough protective layer thickness.In the embankment slope retaining; Bigger at the width that bankets; Under the situation that the body itself that bankets is not enough to keep stable; The part of the anchor pole that bankets can be arranged in the undisturbed soil that links to each other with the zone of banketing; As shown in Figure 6; The anchor pole that bankets in undisturbed soil partly is undisturbed soil anchoring section (6), and the structure construction of undisturbed soil anchoring section (6) also comprises the body of rod (2) and anchoring body (3) two parts composition, can implement with reference to existing anchor pole technology.Present embodiment mainly combines Fig. 2 to Fig. 6 with the lower part, introduces the job practices of the slope retaining Composite Bolt of banketing.As shown in Figure 2; The first step in job practices; After the on-the-spot undisturbed soil removing surface; The gradient of the line of slope (9) of mensuration undisturbed soil as shown in Figure 2; Status requirement in conjunction with the slope retaining Composite Bolt of banketing in line of slope (9) and the design drawing; The first step is accomplished in the anchor pole of confirming undisturbed soil anchoring section (6) mouthful position (5) of burying, and gets into for the 2nd step.In this step; It mainly is the construction of before banketing, accomplishing relevant position undisturbed soil anchoring section (6); Can adopt existing anchor rod construction method to accomplish; In this step; As shown in Figure 3; Can be as required; Before fill construction, accomplish the construction of whole undisturbed soil anchoring sections (6); Also can combine with the layered backfill construction sequence; The bottom-up undisturbed soil anchoring section (6) of before the covering of banketing, successively constructing, the body of rod (2) of undisturbed soil anchoring section (6) can adopt the reinforcement fabrication of 1 diameter 32, and anchoring body (3) is optional to be made with cement paste or cement mortar; Thereby accomplished for second step, got into for the 3rd step.In this step; As shown in Figure 4; Bottom-up backfill soil is successively passed through the top of anchor pole section (7) to the banketing of slope retaining Composite Bolt of banketing; And setting the banket interior side slope (8) consistent with the slope retaining Composite Bolt direction of banketing; Can on the interior side slope (8) of banketing, open the groove of 300mm * 300mm; The thick mortar of first backfill 50mm in groove; Then the steel pipe (10) of diameter 73mm, thickness 4mm is positioned over the top of mortar; And the body of rod (2) that the reinforcing bar conduct of a diameter 32mm of placement is banketed and passed through anchor pole section (7) in steel pipe (10); And locator (4) is set on the body of rod (2); To guarantee that the body of rod (2) is positioned at the center of steel pipe (10); The reinforcing bar of the undisturbed soil anchoring section (6) of having constructed is connected as one as the body of rod (2) with the reinforcing bar that passes through anchor pole section (7) that bankets; The mortar of the thick 150mm of backfill covers steel pipe (10) in groove afterwards, then fluting is filled and led up.Embedding steel pipe (10) has been formed the load transfering strip that bankets (1) of the slope retaining Composite Bolt of banketing of the present invention with the mortar that is covered in steel pipe (10) in this step; For improve the load transfering strip that bankets (1) and banket between bonding strength, can one or more block mortars or concrete structure be set along steel pipe (10) diverse location.The load transfering strip (1) that bankets can increase the stability of the body that bankets in the fill construction process.In this step; Between invar pipe (10) and the body of rod (2) be not set firm the connection; Therefore; In the fill construction process; Even bigger banket sedimentation and horizontal movement occur; Be positioned at the inner body of rod (2) of steel pipe (10) and under the protection of steel pipe (10), can be damaged, steel pipe (10) can also protect the body of rod (2) not to be compacted work progress factor affecting such as machinery in the fill compaction process, has guaranteed that simultaneously undisturbed soil anchoring section (6) is not destroyed in the fill construction process.Thereby accomplished for the 3rd step, got into for the 4th step.Mainly be according to one deck soil under the fill construction requirement backfill in this step, repeated for the 3rd step, as shown in Figure 5.Thereby got into for the 5th step.In this step; As shown in Figure 6; Treat that fill construction thickness is enough; After fill construction is eliminated the destructive factor of the slope retaining Composite Bolt of banketing; In steel pipe (10), inject cement paste or cement mortar; Treat the anchoring body (3) that just having formed after cement paste or cement mortar are solidified bankets passes through anchor pole section (7), the body of rod (2) of the slope retaining Composite Bolt of banketing accomplished of will constructing then with by anchoring body (11) locking, form the side slope anchored bolt retaining wall supporting of banketing.By anchoring body (11) can be to spray the steel concrete barricade, also can be soil-baffling structures such as antislide pile, lattice girder.Thereby accomplish the slope retaining Composite Bolt construction of banketing of the present invention.
This patent includes but not limited to other job practicess of the alternative use of professional person in this area.
