Description

Technical Field

[0001] The utility model relates to the technical field of municipal engineering construction equipment, and more specifically, to a mobile concrete placing machine platform for cast-in-place integrated pipe corridors. Background Art

[0002] During cast-in-place concrete construction of existing open-cut integrated pipe corridors, as they are often laid out on existing roads, it is impossible to use truck-mounted pumps outside the foundation pit to directly pump concrete. Instead, concrete can only be poured using ground pumps installed along the length of the integrated pipe corridor's foundation pit. However, integrated pipe corridors are typically buried deep, and support beams are installed within the deep foundation pit, limiting the depth of the pit. Therefore, concrete cannot be poured using a concrete placing boom (due to its height colliding with the support beams). Concrete can only be poured using a ground pump, long-distance pumping pipes, and manual assistance.

[0003] When pouring concrete using a ground pump and pumping pipe, due to the planned box culvert partition wall, it is impossible to cross the partition wall from a single compartment to other compartments in the foundation pit across the width of the foundation pit, which means that the pouring cannot cover the entire width of the foundation pit. In addition, along the length of the foundation pit, the pumping pipe must be continuously installed and removed to the pouring point according to the length of the concrete pouring. This method has low construction efficiency, a large manual installation and removal workload, and repeated installation and removal operations. There are long construction breaks during the installation and removal process, which can easily cause discontinuous concrete pouring and form cold joints, thus affecting the quality of the project.

[0023] Various embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. In each of the accompanying drawings, identical elements are represented by identical or similar reference numerals. For the sake of clarity, the various parts in the accompanying drawings are not drawn to scale.

[0024] Conventional utility corridors are laid within the red line of the existing road. To ensure uninterrupted traffic, during construction, the construction enclosure is placed close to the perimeter of the utility corridor's foundation pit, leaving no working space outside the pit (unable to accommodate a concrete truck pump). Furthermore, utility corridors are typically buried at a depth of more than 7 meters. When constructed within urban roads, open excavation with vertical supports is often employed to protect surrounding roads and buildings. The deep excavation within the foundation pit requires multiple supports. This limits the depth of the pit, making it impossible to use a concrete placing boom to pour concrete within the pit (due to its height colliding with the support beams).

[0025] In order to solve the problems existing in the prior art, the present invention provides a mobile concrete placing machine platform for cast-in-place integrated pipe corridor. Figure 1 and Figure 2 The mobile concrete placing boom platform for cast-in-place integrated pipe gallery comprises: a concrete placing boom 1, a track 4, and a foundation pit top support beam 6; wherein, a plurality of the foundation pit top support beams 6 are transversely arranged at the top of the integrated pipe gallery foundation pit, two of the tracks 4 are fixedly connected to the tops of the plurality of the foundation pit top support beams 6, and the two tracks 4 are parallel and spaced apart along the width direction of the integrated pipe gallery foundation pit; two rows of support wheels 3 are symmetrically arranged at the bottom of the concrete placing boom 1, and the two rows of support wheels 3 are respectively rollingly connected to the two tracks 4.

[0026] The mobile concrete placing boom platform for cast-in-place integrated pipe corridor solves the technical problem in the prior art that the concrete placing boom 1 cannot be arranged for pouring concrete due to limited space in the depth direction of the foundation pit by movably setting the concrete placing boom 1 on the track 4 on the support beam 6 at the top of the foundation pit.

[0027] Specifically, to facilitate the installation of support wheels 3 at the bottom of the material distribution boom 1, a steel plate base 2 is horizontally disposed at the bottom of the material distribution boom 1, with two rows of support wheels 3 disposed at the bottom of the steel plate base 2. In this embodiment, the steel plate base 2 is made of rectangular steel plate, and the base 1 of the material distribution boom is welded and fixed to the steel plate base 2. Two rows of "L"-shaped support frames 31 are symmetrically disposed at the bottom of the steel plate base 2, and the support wheels 3 are rotatably connected to these support frames 31. In this embodiment, a total of eight support wheels 3 are disposed at the bottom of the steel plate base 2, with four support wheels 3 in each row, and each support wheel 3 is rotatably connected to a corresponding "L"-shaped support frame 31.

[0028] In this embodiment, the track 4 is a C-shaped steel, and the support wheel 3 is connected to the groove of the C-shaped steel in a rolling manner. The support wheel 3 is a steel roller, and the diameter of the support wheel 3 matches the size of the groove of the C-shaped steel. The groove of the C-shaped steel refers to a groove-shaped channel formed by the web, two wing plates and two wing plate curlings of the C-shaped steel. By rolling a row of support wheels 3 formed by multiple support wheels 3 in the groove of the C-shaped steel, the diameter of the support wheel 3 matches the size of the groove of the C-shaped steel, thereby ensuring that the support wheel 3 can slide steadily along the longitudinal direction of the C-shaped steel, and there is no gap between the support wheel 3 and the inner side wall of the C-shaped steel, and they are completely consistent, so that the fabricator 1 can run firmly along the track 4. At the same time, the C-shaped steel has sufficient rigidity to support the load of the top fabricator 1. Since the support wheel 3 in this embodiment is rotatably connected to the "L"-shaped support frame 31, when the support wheel 3 is set in the groove of the C-shaped steel, the lower end of the "L"-shaped support frame 31 passes through the opening of the C-shaped steel and into the groove of the C-shaped steel, and will not interfere with the C-shaped steel.

[0029] Furthermore, the track 4 is detachably connected to a plurality of the foundation pit top support beams 6. Specifically, the foundation pit top support beams 6 are reinforced concrete structure support beams. When the foundation pit top support beams 6 of the integrated pipeline corridor foundation pit are constructed, embedded bolts are provided on the foundation pit top support beams 6. The embedded bolts are detachably connected with "J"-shaped fixing buckles 5. The track 4 is pressed and fixed to the foundation pit top support beams 6 by the fixing buckles 5. The fixing buckles 5 can be buckled on the track 4. Bolt holes are provided on both sides of the fixing buckle 5. The bolt holes on the fixing buckle 5 are sleeved on the embedded bolts of the foundation pit top support beams 6 and are locked and fixed by screwing nuts. By detachably connecting the track 4 to the foundation pit top support beams 6, after pouring a section of integrated pipeline corridor concrete, the track 4 can be removed from the foundation pit top support beams 6 and moved to the foundation pit top support beams 6 above the unpoured area for reuse.

[0030] In this embodiment, the two ends of the foundation pit top support beam 6 are fixed to the top of the foundation pit support piles 9 on both sides of the integrated pipe gallery foundation pit. Below each of the foundation pit top support beams 6, a foundation pit middle support beam 10 is also provided. The foundation pit middle support beam 10 is a steel beam. The two ends of the foundation pit middle support beam 10 are fixed to the middle of the foundation pit support piles 9 on both sides of the integrated pipe gallery foundation pit, and are used to support the foundation pit support piles 9 on both sides of the foundation pit.

[0031] Furthermore, the length of the track 4 is consistent with the casting length of each section of the integrated pipe corridor. With this arrangement, after casting a section of the integrated pipe corridor, the concrete placing boom 1 can be moved to the track 4 above the area where the next section of the integrated pipe corridor is to be cast, and the previous section of the track 4 can be disassembled and then installed on the foundation pit top support beam 6 above the next section of the integrated pipe corridor to be cast.

[0032] In order to better illustrate the structure and application method of the present invention, an open-cut cast-in-place multi-compartment integrated pipe corridor with a burial depth of 8m is used as an example. In the foundation pit, two layers of support beams are set (multiple support beams on each layer are 4m / row along the length of the foundation pit). The first layer of support beams is the top support beam 6 of the foundation pit flush with the excavation ground. The top support beam 6 of the foundation pit is a reinforced concrete support beam. The second layer of support beams is the middle support beam 10 of the foundation pit. The middle support beam 10 of the foundation pit is a steel beam. The middle support beam 10 of the foundation pit is 3m away from the base (the height of the pipe corridor is 4m). The length of the integrated pipe corridor is 1km, and the expansion joint is 25~30m / row along the length of the pipe corridor (that is, a whole section of the integrated pipe corridor is cast every 25~30m). The specific construction process is as follows:

[0033] After the excavation of the foundation pit is completed, foundation pit support piles 9 are vertically installed on both sides of the foundation pit. A mold-cast foundation pit top support beam 6 is supported on the top of the foundation pit support piles 9. At the same time, a foundation pit middle support beam 10 is installed in the middle of the foundation pit support piles 9 to support the foundation pit support piles 9 on both sides of the foundation pit. During the construction of the foundation pit top support beam 6 of the reinforced concrete structure, embedded bolts are set on the foundation pit top support beam 6. The position of the embedded thread corresponds to the installation position of the track 4. The embedded bolts are used to cooperate with the fixing buckle 5 to compress and fix the track 4.

[0034] After the installation of the foundation pit support and the excavation of the integrated pipeline corridor are completed, the reinforcement of the bottom plate and side walls of the integrated pipeline corridor 8 will be tied, and the bottom plate formwork will be supported to complete the preparation work for pouring concrete for the integrated pipeline corridor 8.

[0035] A steel plate base 2 is welded to the bottom of the material placing machine 1, two rows of support frames 31 are symmetrically arranged at the bottom of the steel plate base 2, and multiple support wheels 3 are respectively installed on the corresponding support frames 31 to form an integral movable material placing machine 1. Figure 3 shown.

[0036] The C-shaped steel track 4 is fixed to the multiple foundation pit top support beams 6 above the area where the integrated pipe corridor is to be poured, using fixing buckles 5. The fixing buckles 5 are fastened to the embedded bolts on the foundation pit top support beams 6 with nuts. The track 4 extends along the longitudinal direction of the integrated pipe corridor, and the length of each track 4 corresponds to the planned pouring length of each section of the integrated pipe corridor 8 (25-30m).

[0037] The supporting wheel 3 of the material placing boom 1 is passed through the end of the C-shaped steel track 4 along the groove, so that the assembled movable material placing boom 1 is smoothly installed on the C-shaped steel track 4.

[0038] The ground pump 7 is set on the unexcavated ground of the integrated pipe gallery or on the ground where backfill has been completed, and the pumping pipe is connected to the concrete placing machine 1 along the direction of the integrated pipe gallery foundation pit. The pumping pipe is longitudinally placed on the top of the integrated pipe gallery foundation pit support pile 9;

[0039] According to the position change of the pouring point of the integrated pipeline corridor 8, the concrete placing machine platform is moved using the installed C-shaped steel channel and support wheel 3, and moved along the length direction of the integrated pipeline corridor foundation pit. The concrete placing machine 1 can unfold the rotating concrete placing arm in the horizontal direction to cover the entire width of the integrated pipeline corridor 8, thereby quickly completing the concrete pouring in the width and length directions of the integrated pipeline corridor 8.

[0040] The mobile concrete placing machine platform for cast-in-place integrated pipe corridors provided by the present invention has a simple structure, is easy to manufacture, and is convenient to operate, and can be completed without purchasing special materials and equipment. By setting two tracks in parallel on the top support beam of the foundation pit at the top of the integrated pipe corridor, and symmetrically setting two rows of support wheels at the bottom of the concrete placing machine, the concrete placing machine can move on the tracks through the support wheels at the bottom, thereby completing the pouring of the integrated pipe corridor concrete quickly and efficiently, reducing the workload of installing and removing pipes, saving the intermittent time during pouring, ensuring the continuity of the integrated pipe corridor concrete pouring, and improving the construction efficiency and quality of the integrated pipe corridor concrete pouring.
