Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of deep foundation pit support and road high slope support, and particularly relates to a reinforcing tool and method for single-side cast-in-place formwork of a special-shaped pile-slab wall. BACKGROUND

[0002] With the continuous innovation and improvement of the municipal road engineering construction technology, the scale of municipal infrastructure construction is also expanded. The municipal road slope support is an important link in the municipal road construction, and the construction quality of this link directly affects the quality of the urban road engineering and the safety of people's lives, and therefore must be highly valued. The municipal road slope support generally adopts support forms such as row piles and gravity type retaining walls. The anti-sliding pile support slope is one of them. In the traditional construction of the anti-sliding pile, the crown beam is made on the top of the anti-sliding pile after the anti-sliding pile is completed, and the vertical distribution bars of the retaining wall are pre-buried, and finally the retaining wall is supported.

[0003] The special-shaped pile-slab wall is quite different from the ordinary pile-slab wall in structure. The special-shaped pile-slab wall is a support structure in which the retaining wall is arranged between the anti-sliding piles, and the steel bars are pre-buried between the anti-sliding piles for connecting the steel bars of the retaining wall. The characteristic of this type of pile-slab wall is that one side of the anti-sliding pile is the soil body, and the other side is the cast-in-place concrete retaining wall on the road side, which leads to the fact that the conventional formwork reinforcing method cannot be used, the retaining wall construction operation cannot be carried out, and the forming quality of the retaining wall after pouring cannot be guaranteed. Compared with the traditional retaining wall, this slope support has a lower risk coefficient and can save construction cost, greatly ensuring the stability of the slope and the safety of the construction personnel in the operation area.

[0004] At present, in the construction of the special-shaped pile-slab wall, for the double-side cast-in-place slab, most of the time, the two sides of the formwork are tightly fixed by using the tensioning screw rod. For the single-side cast-in-place slab, the reinforcing method mostly adopts the external support scaffold steel pipe, which is set by means of counter-support, and the reaction force of the external support scaffold is applied to the pile-slab wall, or the tensioning screw rod is welded to the distribution steel bars of the retaining wall for fixation, and then the construction is carried out by layer-by-layer pouring. The overall stability of the traditional method support frame is low, and the anti-overturning capacity is small. When the pouring height of the concrete is high, the lateral pressure of the concrete on the formwork is large, the tensioning screw rod is easily broken, the concrete is expanded and exploded, and the construction quality of the retaining wall cannot be guaranteed.

[0041] The embodiment discloses a reinforcing method for a single-side cast-in-place formwork of a special-shaped pile-slab wall.

[0042] Specifically, the reinforcing construction method for the lower segment single-side cast-in-place formwork of the special-shaped pile-slab wall is as follows.

[0043] (1) Before starting to set the retaining wall formwork, the pre-buried circular steel bars 1 and the pre-buried stabilizing steel bars 2 are uniformly chiseled out.

[0044] (2) The cast-in-place formwork 3 is stably fixed in position by the pre-buried stabilizing steel bars 2, and the first vertical reinforcing beams 11 are uniformly distributed and stand between the cast-in-place formworks 3.

[0045] (3) The supporting I-beams 4 are pushed and slid to the middle of the adjacent anti-sliding piles by the universal wheels 16.

[0046] (4) The reinforcing inclined braces 9 are connected with the supporting I-beams 4 by bolting, and the inclined brace connecting plates 10 and the horizontal reinforcing beams 7 are simultaneously installed.

[0047] The first steel bars 6 are connected with the pre-buried circular steel bars 1 by the locking clamps 8 at equal intervals in the vertical direction, then the first steel bars 6 are clamped on the wooden wedges 17 with sliding grooves, the wooden wedges 17 are manually hammered tightly, the supporting I-beams 4 are tightly pressed against the horizontal and vertical reinforcing beams and the cast-in-place formwork 3, the reinforcing method has the advantages of remarkable reinforcing effect and the ability to greatly increase the rigidity of the formwork to resist the lateral pressure of the concrete on the formwork, ensure the height of the once-poured concrete, and save the construction period. One pouring can pour 3-4 rows of forms.

[0048] The reinforcing construction method for the upper segment single-side cast-in-place formwork of the special-shaped pile-slab wall is as follows.

[0049] (1) Considering that the construction height of the upper segment is high, the crane needs to be coordinated, therefore, the combined angle steels 13 are selected for reinforcement, one of which has light weight and large rigidity, and the other of which is selected to be bolted and combined to increase the rigidity for the safety of the construction operation.

[0050] (2) First, the suspension cable 18 is welded on the retaining wall steel mesh reinforcement at equal intervals, used for hanging the angle steel 13.

[0051] (3) The cast-in-place formwork 3 is stably fixed by the pre-embedded stabilizing steel bars 2, and the second vertical reinforcing beams 15 are evenly distributed between the cast-in-place formwork 3 by horizontally and vertically setting stabilizing at equal intervals, and are fixed by using the tension bolts.

[0052] (4) The combined angle steel 13 is installed and hung on the suspension cable 18, and then the circular tube transverse reinforcing beam 7 is inserted along the vertical direction.

[0053] (5) The second steel bar 19 is connected with the pre-embedded circular ring steel bar 1 by using the locking clamp 8 along the vertical direction at equal intervals, and then the jack 12 is installed, which is provided with a clamping groove for pushing the second steel bar 19, and the pushing force is applied synchronously, so that the force of the jack 12 is reversely transmitted to the formwork, thereby ensuring the rigidity and stability of the cast-in-place formwork 3.

[0054] (6) This method is repeated for reinforcement, and this method can ensure that several adjacent sections form a flow process, greatly saving the construction period and accelerating the construction efficiency.

[0055] The second steel bar 19 is provided in three rows, which are respectively arranged at the bottom, top and middle of the cast-in-place pile wall. The steel bar frame can be conveniently disassembled and reused after the formwork is removed, and is removed before the pile wall concrete is hardened and formed, and is reused.

[0056] The above is only a preferred embodiment of the present application, and is not used to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
