Description
Technical Field
[0001] The utility model belongs to the field of foundation pit support, in particular to a comprehensive support structure in which a concrete wall serves as a pile row water stop and a pile retaining wall. Background Art
[0002] Traditional support technology using prestressed anchors and piles is suitable for conditions with good soil quality and no groundwater within the excavation depth. The anchor structure utilizes prestressed anchors, which are connected by steel beams and tensioned against the piles. Shotcrete is typically used for simple support between the piles. If groundwater is present within the excavation depth, a waterstop curtain or pit dewatering may be necessary.
[0003] This combined support structure has the following problems in practical application:
[0004] From a force perspective: First, prestressed anchors act on the piles via steel beams, but these beams are easily deformed by collisions with construction equipment during excavation, affecting their force transmission. Second, the soil between the piles must be excavated before construction of the retaining walls between the piles. This often creates an uneven surface, making the quality of the retaining walls formed by the subsequent shotcrete injection impossible, thus affecting force transmission between the piles.
[0005] From the perspective of water stopping: when there is groundwater within the excavation depth of the foundation pit, shotcrete cannot serve as an independent water retaining structure. Setting up a water-stop curtain or dewatering the foundation pit alone will increase costs and construction period, and it is easy to affect the surrounding area during construction. Utility Model Content
[0006] The purpose of the utility model is to provide a comprehensive support structure of a concrete wall that serves as both a pile row water stop and a pile retaining wall, and to solve the problem that the existing pile row prestressed anchor rod combined support technology has two aspects, namely, the stress angle and the water stop angle, which affect the support stress and water stop.
[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0008] A comprehensive support structure for a concrete wall that serves as both a pile row water stop and a pile retaining wall, comprising an inner pile row support, soil between the pile rows, and a cast-in-place concrete wall adjacent to the outer side of the pile row support. The cast-in-place concrete wall comprises wall reinforcement and wall concrete. The wall reinforcement is a steel cage comprising vertical force bars arranged in pairs and horizontal ladder bars arranged between each pair of vertical force bars.
[0009] The pile support and the cast-in-place concrete wall are connected by the tie bars between the piles. The inner half of the tie bars between the piles are embedded in the pile support, and the outer half of the tie bars between the piles are embedded in the cast-in-place concrete wall. The tie bars between the piles are arranged at intervals along the height direction of the pile support. The tie bars between the piles on each pile row are arranged in groups along the length direction of the cast-in-place concrete wall.
[0010] The soil between the piles and the cast-in-place concrete wall are connected by a set of prestressed anchor systems.
[0011] The prestressed anchor system includes a steel strand anchor rod. The steel strand anchor rod passes through the soil between piles and the cast-in-place concrete wall from the inside to the outside to form a three-part force transmission structure, namely the solidified part in the soil between piles, the embedded part in the wall, and the anchor part outside the wall. The steel strand anchor rod corresponds to the solidified soil section between piles, the free section in the wall, and the anchor head section outside the wall from the inside to the outside of the three-part force transmission structure.
[0012] The soil solidification section between piles is solidified in the soil between piles.
[0013] The embedded part in the wall includes a through-wall steel sleeve located in the cast-in-place concrete wall, which passes through the free section in the wall and is placed in the through-wall steel sleeve. The outer end of the free section in the wall passes through the through-wall steel sleeve.
[0014] The outside-wall anchor head section is anchored at the outside-wall anchoring portion.
[0015] The top surface of the cast-in-place concrete wall is at the same height as the pile row support. A pile row crown beam is provided on the top surface of the pile row support. The pile row crown beam is also provided on the top surface of the cast-in-place concrete wall and widened to be flush with the outer surface of the cast-in-place concrete wall.
[0016] Each pair of vertical stress-bearing reinforcement includes outer wall reinforcement and inner wall reinforcement correspondingly arranged along the inner and outer sides of the cast-in-place concrete wall.
[0017] The tie bars between the wall piles are fixedly connected to the outer and inner wall bars. The outer end faces of the tie bars between the wall piles are flush with the outer surface of the wall concrete. Each section of the cast-in-place concrete wall is equipped with two rows of tie bars between the wall piles, namely the upper row of tie bars and the lower row of tie bars.
[0018] The horizontal ladder reinforcement is fixedly connected between the outer and inner reinforcements of the wall along the thickness direction of the cast-in-place concrete wall.
[0019] The cast-in-place concrete wall is arranged in sections along the height direction. The horizontal ladder bars in each section of the cast-in-place concrete wall are arranged at intervals up and down along the height direction of the cast-in-place concrete wall. The horizontal ladder bars are located between the upper row of tie bars and the lower row of tie bars, namely the upper ladder bars and the lower ladder bars. The prestressed anchor rod system is located between the upper ladder bars and the lower ladder bars.
[0020] The through-wall steel sleeve is high on the outside and low on the inside and is pre-buried in the cast-in-place concrete wall. The outer end and inner end of the through-wall steel sleeve are fixedly connected to the outer reinforcement and inner reinforcement of the wall respectively.
[0021] The embedded part in the wall also includes horizontal structural reinforcement bars. The two ends of the horizontal structural reinforcement bars are fixedly connected to the outer sides of the outer wall reinforcement bars on the left and right sides of the wall-penetrating steel sleeve. The horizontal structural reinforcement bars are respectively fixedly connected to the upper and lower sides of the outer end of the wall-penetrating steel sleeve. The wall-penetrating steel sleeve and the horizontal structural reinforcement bars are fixedly connected to the wall steel bars in the cast-in-place concrete wall.
[0022] The embedded part in the wall also includes a steel plate, which is fixedly connected to the outer end face of the wall-penetrating steel sleeve. The outer surface of the steel plate is flush with the outer surface of the wall concrete. A rod hole is opened in the center of the steel plate, and the outer end of the free section passing through the wall passes through the rod hole.
[0023] The external wall anchoring part includes a wedge-shaped pressure plate and an anchor. The wedge-shaped pressure plate is provided with a through-plate hole. The external wall anchor head section passes through the through-plate hole and is anchored on the wedge-shaped pressure plate through the anchor.
[0024] The inter-pile soil solidification part includes an anchor hole formed on the inter-pile soil along the angle of the wall-penetrating steel sleeve. The inter-pile soil solidification section is placed in the anchor hole and forms a grouting solidification body with the grouting in the anchor hole.
[0025] When located below the groundwater level, the middle of the wall-penetrating steel sleeve is fixedly connected to a circular water-stop flange of the vertical cylinder.
[0026] Compared with the prior art, the present invention has the following features and beneficial effects:
[0027] In the utility model, the row pile support and the concrete wall on the pile side are specifically connected through the tie bars between the wall piles, and the concrete wall and the soil between the piles are connected and force is transmitted through the prestressed anchor rod system, so that the concrete wall, the row pile support and the soil between the piles are firmly connected.
[0028] The utility model eliminates the traditional method of transmitting force with a steel waist beam during pile prestressed anchor support. A steel sleeve is embedded in the concrete wall, and the prestressed anchor can be bored through the steel sleeve. A steel pad can also be installed at the hole of the steel sleeve to directly tension the anchor. The prestressed anchor can be directly anchored to the surface layer of the reinforced concrete wall through a pressure plate, thereby ensuring the overall force transmission of the support structure.
[0029] The utility model is a combined support of pile row support and pile side concrete wall. The reinforced concrete wall on the pile side replaces the sprayed concrete between the piles. The concrete wall is directly used as the retaining member between the piles to achieve soil support between the piles and ensure the force transmission effect between the piles. The anti-seepage effect of the concrete wall can also be used to achieve the groundwater interception requirement and achieve a water-stopping effect, so that the support structure does not need to be separately set up with a foundation pit dewatering or water-stopping curtain on the outside.

[0050] The soil between the piles 2 is connected to the cast-in-place concrete wall 3 by a set of prestressed anchor systems 7.
[0051] The prestressed anchor rod system 7 includes a steel strand anchor rod 71. The steel strand anchor rod 71 passes through the pile soil 2 and the cast-in-place concrete wall 3 from the inside to the outside to form a three-part force transmission structure, namely the solidified part in the pile soil, the embedded part in the wall and the anchor part outside the wall. The steel strand anchor rod 71 corresponds to the pile soil solidified section 711, the free section 712 passing through the wall and the anchor head section 713 outside the wall in the three-part force transmission structure from the inside to the outside.
[0052] The embedded portion in the wall includes a through-wall steel sleeve 72 located within the cast-in-place concrete wall 3. A free section 712 extends through the wall and is inserted into the through-wall steel sleeve 72. The outer end of the free section 712 extends out of the through-wall steel sleeve 72. When located below the groundwater level, a vertical cylindrical circular waterstop flange 9 is fixedly connected to the center of the through-wall steel sleeve 72.
[0053] The wall-penetrating steel sleeve 72 is high on the outside and low on the inside and is pre-buried in the cast-in-place concrete wall 3.

The wall-penetrating steel sleeve 72 and the horizontal structural reinforcement ribs 73 are both fixedly connected to the wall steel bars in the cast-in-place concrete wall 3.
[0055] The embedded part in the wall also includes a steel plate 74, which is fixedly connected to the outer end face of the wall-penetrating steel sleeve 72. The outer surface of the steel plate 74 is flush with the outer surface of the wall concrete. A rod hole 741 is opened in the center of the steel plate 74, and the outer end of the free section 712 passing through the wall passes through the rod hole 741.
[0056] The inter-pile soil solidification section 711 solidifies within the inter-pile soil 2. The inter-pile soil solidification portion includes an anchor hole 21 formed in the inter-pile soil 2 along the angle of the through-wall steel sleeve 72. The inter-pile soil solidification section 711 is placed in the anchor hole 21 and forms a grouting solidification body with the grouting in the anchor hole 21.
[0057] The external wall anchor head section 713 is anchored in the external wall anchoring portion. The external wall anchoring portion includes a wedge-shaped pressure plate 75 and an anchor 76. The wedge-shaped pressure plate 75 has a through-plate hole 751. The external wall anchor head section 713 passes through the through-plate hole 751 and is anchored to the wedge-shaped pressure plate 75 through the anchor 76.
[0058] The cast-in-situ concrete wall 3 is arranged in sections along the height direction of the support body according to the construction excavation surface, including the completed wall 31 of the upper section and the construction wall 32 of the current layer. The thickness of the cast-in-situ concrete wall 3 is 300mm-400mm.
[0059] See also Figure 9-13 As shown, the bottom connection end of the upper steel bar connection sleeve 10 extends downward from the bottom surface of the upper completed wall 31, corresponding to the position of the vertical force reinforcement 4. The bottom surface of the current construction wall 32 is flush with the current earth excavation surface 11. The current steel bar connection sleeve 12 is pre-embedded on the current earth excavation surface 11, corresponding to the position of the vertical force reinforcement 4. The top connection end of the current steel bar connection sleeve 12 is exposed from the current earth excavation surface 11. The upper steel bar connection sleeve 10 corresponds to the current steel bar connection sleeve 12 in the upper and lower directions. In this embodiment, the upper steel bar connection sleeve 10 and the current steel bar connection sleeve 12 are both straight threaded sleeves. Both ends of the vertical force reinforcement 4 of the current construction wall 32 are threaded and threadedly connected to the top connection end of the current steel bar connection sleeve 12 and the bottom connection end of the upper steel bar connection sleeve 10, respectively.
[0060] This kind of concrete wall serves as a comprehensive support structure for pile water stop and soil retaining between piles. The basic construction steps are as follows:
[0061] Step 1: Position the pile support 1 outside the foundation pit according to the requirements of the design drawings, and then construct the pile support 1.
[0062] Step 2: Use excavation machinery to excavate the trench section step by step close to the side wall of the pile row. The excavation width is greater than the thickness of the cast-in-place concrete wall 2 and the wall reinforcement cage is placed below.
[0063] The excavation dimensions of the staged trench section are as follows:
[0064] First, excavate to 0.5m above the groundwater level, then use a telescopic arm grab to excavate in sections. Excavation length: each section excavation length is not more than 6m; excavation depth: not more than 2m; add a dewatering step, and drill a drainage well inside the foundation pit near the cast-in-place concrete wall 2; the drainage well is to facilitate the construction of the next concrete wall to reduce the amount of groundwater gushing out from the outside during excavation.
[0065] Step three, after the construction of the upper section of the completed wall 31 is completed, the earth within the range of the current construction wall 32 is excavated downwards, the bottom of the upper section of the completed wall 31 is chiseled out to expose the bottom connection end of the upper section of the steel bar connecting sleeve 10, and then excavation is carried out to the bottom excavation surface of the current construction wall 32, that is, the current earth excavation surface 11.
[0066] Step 4: Design and drill anchor holes on the pile body of the pile support 1 for implanting the tie bars 6 between the wall piles. The anchor holes are located at the top and bottom of the construction wall 32 of this layer; the anchor holes are divided into top anchor holes and bottom anchor holes. The top anchor holes are two in a row horizontally, and the bottom anchor holes are two in a row, that is, the two anchor holes in each row are at the same height on the corresponding pile row and are symmetrically arranged on the left and right.
[0067] Step 5: bury and install the current layer steel bar connection sleeve 12 at the position corresponding to the upper section steel bar connection sleeve 10 on the current layer earth excavation surface 11, and expose its top connection end.
[0068] Step six: implant the tie bars 6 between the wall piles in the anchor holes. The protruding length of the tie bars 6 between the wall piles is equal to the thickness of the cast-in-place concrete wall 2 .
[0069] Step 7: Install the wall reinforcement cage. The upper and lower ends of the vertical stress reinforcement of the wall reinforcement cage are threaded before installation. Then, the lower end of the vertical stress reinforcement is first threadedly connected to the current layer reinforcement connection sleeve 12, and then the upper end of the vertical stress reinforcement is threadedly connected to the upper section reinforcement connection sleeve 10;
[0070] The construction steps for installing the wall reinforcement cage in step seven are as follows:
[0071] Step a: first install the inner wall reinforcement 42 between the top connection end of the current layer steel bar connection sleeve 12 and the bottom connection end of the upper section steel bar connection sleeve 10;
[0072] Step b, then fix the outer wall reinforcement 41 and the double-layer horizontal ladder reinforcement 5 into a whole;
[0073] Step c: The middle part of the through-wall steel sleeve 72 is fixedly connected to the double-layer horizontal ladder reinforcement 5 by setting two vertical connectors, so that the through-wall steel sleeve 72 is fixedly connected to the outer wall reinforcement 41 and the double-layer horizontal ladder reinforcement 5 into a whole;
[0074] Step d: Weld a steel backing plate 74 to the front end surface of the wall-penetrating steel sleeve 72, and weld a circular water-stop flange 9 to the steel sleeve;
[0075] Step e: fix the horizontal structural reinforcement ribs 73 to the upper and lower sides of the front end of the through-wall steel sleeve 72 behind the steel backing plate 74 and the outer sides of the wall outer ribs 41 on the left and right sides of the through-wall steel sleeve 72;
[0076] Step f, lower the wall-penetrating steel sleeve 72, the outer wall reinforcement 41 and the double-layer horizontal ladder reinforcement 5 into the groove section as a whole, close to the inner wall reinforcement 42 when lowering, and fix the inner wall reinforcement 42 to the upper ladder reinforcement 51 after lowering to the design elevation; to prevent concrete from flowing into the interior of the wall-penetrating steel sleeve 72 during concrete pouring, foam should be filled inside the two ends of the wall-penetrating steel sleeve 72 after the wall-penetrating steel sleeve 72 is installed.
[0077] Step 8. Hoist the formwork for this layer into the outside of the groove section. After hoisting the formwork for this layer into the wall, first install the top form reinforcement to fix the formwork, and then backfill the soil on the outside of the formwork for this layer to prevent the formwork from shifting during concrete pouring.
[0078] Step nine: After the formwork of this layer is installed and fixed, plug the pouring hose to the bottom of the groove section, and then pour the wall concrete. After the age and strength of the wall concrete meet the requirements, remove the formwork of this layer.
[0079] Step 10. After the current layer of formwork is removed, the prestressed anchor system 7 is constructed. First, the hole of the through-wall steel sleeve 72 is cleaned, and the prestressed anchor system 7 is drilled into the soil 7 between the piles through the through-wall steel sleeve 72. After the drilling is completed, the steel strand anchor 71 is placed and grouting is performed to anchor it.
[0080] Step 11: After the age and strength of the grouting solidification body meet the requirements, install the wedge-shaped pressure plate 75, pass the steel strand anchor rod 71 through the wedge-shaped pressure plate 75, and then install the anchor 76 to tension the steel strand anchor rod 71.
[0081] In step 12, the construction wall 32 of this layer now becomes the upper section of the completed wall 31, and the next section of earthwork is excavated. The cast-in-place concrete wall 3 needs to be cast to 0.7m below the elevation of the prestressed anchor system 7 first. After the construction of the prestressed anchor system 7 is completed, the next section of earthwork is excavated. Repeat steps 3 to 9 until the earthwork is excavated to the base elevation, until all sections are constructed and the cast-in-place concrete wall 3 is formed as a whole.
