[0002] Existing concrete pits require a lot of time for processes such as steel sheet pile support, foundation pit excavation, foundation treatment, formwork support, steel bar tying, concrete pouring, concrete curing, formwork removal, backfilling and sealing. The manual on-site integral pouring is inefficient and not conducive to the expansion of later renovation and maintenance.

[0003] At the same time, the cost of existing precast concrete work pits is relatively high, and the transportation and installation of large quantities are somewhat difficult. The joints that remain after splicing are filled with glue or mortar, and the waterproofing effect is not very ideal.

[0007] Among them, a number of cable brackets are provided on the inner side of the prefabricated long side panels, and a horizontally arranged adjustable steel plate is provided between a pair of the relatively arranged cable brackets, and is temporarily fixed by bolts; at the same time, the prefabricated long side panels and the prefabricated short side panels adopt a double-skin wall structure, and cement mortar is evenly spread in the cavity to fix the entire prefabricated working well.

[0008] As a preferred technical solution of the present application, cement mortar is poured into the cavities of the prefabricated long side panels and the prefabricated short side panels to half the height of the wall.

[0009] As a preferred technical solution of the present application, the inner wall skins of the prefabricated long side panels and the prefabricated short side panels are smaller than the outer wall skins.

[0010] As a preferred technical solution of the present application, a plurality of additional reinforcing steel bars are distributed around the prefabricated top plate, and the prefabricated top plate is fixedly connected to the prefabricated long side plates and the prefabricated short side plates through the additional reinforcing steel bars.

[0011] As a preferred technical solution of the present application, the prefabricated long side panels and the prefabricated short side panels are fixed using installation angle brackets.

[0024] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] like Figure 1-2 As shown, the modular assembled prefabricated working shaft of the utility model comprises a prefabricated bottom plate 1, a pair of prefabricated long side plates 2, a pair of prefabricated short side plates 3, a prefabricated top plate 4 and a prefabricated cover plate 5; wherein, the prefabricated long side plates 2 and the prefabricated short side plates 3 are placed around the prefabricated bottom plate 1, the prefabricated top plate 4 is arranged on the inner walls of the prefabricated long side plates 2 and the prefabricated short side plates 3, and the prefabricated cover plate 5 is placed on the maintenance entrance 41 of the prefabricated top plate 4.

[0026] Specifically, a plurality of cable brackets 21 are provided on the inner side of the prefabricated long side panels 2. The cable brackets 21 are used to suspend cables so as to keep a certain distance from the ground, thereby achieving a moisture-proof and beautiful effect.

[0027] Among them, a horizontally arranged adjustable steel plate 6 is provided between a pair of oppositely arranged cable brackets 21, and the cable bracket 21 and the adjustable steel plate 6 are fixedly connected by bolts to play a temporary supporting role; at the same time, the prefabricated long side plate 2 and the prefabricated short side plate 3 are fixed by using installation angle brackets. In addition, part of cement mortar is evenly spread in the cavity of the prefabricated long side plate 2 and the prefabricated short side plate 3 for fixing.

[0028] The prefabricated top plate 4 is placed on the inner wall of the prefabricated long side plate 2 and the prefabricated short side plate 3. At the same time, a plurality of additional reinforcing steel bars 42 are distributed around the prefabricated top plate 4. The prefabricated top plate 4 is fixedly connected to the prefabricated long side plate 2 and the prefabricated short side plate 3 through the additional reinforcing steel bars 42.

[0029] In order to strengthen the stress stability of the components and improve the waterproof effect, reinforcement parts or additional reinforcing steel bars are used at the joints of all components, and layered cement mortar is poured in all gaps to ensure the stability of the components during construction.

[0030] In addition to the above structure, the modular prefabricated work well of the utility model also has the following structural features:

[0031] 1. A pebble cushion is laid under the overall modular prefabricated pit to ensure that the bottom of the foundation is flat and the force is evenly distributed, and the prefabricated bottom plate 1 is placed horizontally in the foundation pit.

[0032] 2. The modular assembled prefabricated working shaft bottom plate adopts prefabricated composite plates, and the clearance height in the working shaft can be flexibly adjusted according to the design requirements to ensure that later personnel can enter the maintenance and take over the space.

[0033] 3. Prefabricated long side panels 2 and prefabricated short side panels 3 adopt a double-skin wall structure. First, the long side walls are arranged. The cable brackets prefabricated in advance on the inner side of the double-skin wall can be used to pull the long side walls on both sides and temporarily fix them with corresponding bolts and adjustable steel plates. Then the short side walls are arranged, and the prefabricated seven-shaped connectors of the wall are used to temporarily fix the inner wall skins of the short side walls and the long side walls.

[0034] 4. Prefabricated long side panels 2 and the prefabricated short side panels 3 have a double-skin wall structure, in which the inner wall is narrower than the outer wall by a certain width, so that the corners of the surrounding walls can fit better; at the same time, the outer wall of the side wall and the bottom plate can also fit better.

[0035] 5. After the surrounding side walls are fixed, pour cement mortar into the cavity to half the height of the wall to make the bottom plate and the side walls more stable. At the same time, it forms a waterproof measure to make the joint gaps more moisture-proof and waterproof.

[0036] 6. After the top plate is placed on the surrounding side walls, additional reinforcing steel bars are used to connect it to the side walls to make its structure more stable. Finally, after the overall cement mortar is poured, the entrance reserved in the top plate is covered with a prefabricated cover plate, which is safer and more convenient.

[0037] 7. The overall size of the modular prefabricated work well can be flexibly adjusted according to design requirements. One or two entrances are set on the top plate to facilitate workers' maintenance. Holes are also reserved on the side walls to facilitate subsequent pipeline connections.

[0038] 8. Use high-strength and high-performance concrete. Because it is very dense, its durability indicators such as impermeability, frost resistance, carbonization resistance, and corrosion resistance are all excellent, which can increase the service life of concrete structures. At the same time, the weight is reduced, which can reduce the risks of transportation and installation.

[0039] According to the above-mentioned modular prefabricated work well, the utility model also proposes a processing method of the modular prefabricated work well, which specifically includes the following steps:

[0040] S10: First, hoist the prefabricated bottom plate 1 to the designated position in the foundation pit, and adjust the position correctly;

[0041] S20: Then, the prefabricated long side panels 2 and the prefabricated short side panels 3 are placed around the prefabricated bottom plate 1. The prefabricated long side panels 2 are connected to the bolts on the work well bracket using the adjustable steel plate 6 to play a temporary supporting role. The prefabricated short side panels 3 are fixed to the prefabricated long side panels 2 using the installation angle brackets.

[0042] S30: After the prefabricated long side panels 2, the prefabricated short side panels 3 and the prefabricated bottom panel 1 are fixed and adjusted, a portion of cement mortar is evenly spread in the cavities of the prefabricated long side panels 2 and the prefabricated short side panels 3 to fix them;

[0043] S40: placing the prefabricated top plate 4 on the inner wall of the prefabricated long side plate 2 and the prefabricated short side plate 3, arranging the steel bars of the prefabricated top plate 4 and connecting it with the prefabricated long side plate 2 and the prefabricated short side plate 3 with additional reinforcing steel bars 42 on all sides;

[0044] S50: After the cement mortar is evenly spread and the overall pouring is completed, the prefabricated cover plate 5 is placed on the maintenance entrance 41 of the prefabricated top plate 4.

[0045] The modular prefabricated work well of the utility model adopts factory production and on-site modular assembly to solve the problems of long on-site construction period and excessive impact on the surrounding environment. The modular assembly method is adopted, and reinforcement parts or additional reinforcement steel bars are used at the splicing positions of all components. After that, cement mortar is poured at all gaps, and the force stability of the overall components is stronger and the waterproof effect is better. High-strength and high-performance concrete is used. Because it is very dense, its durability indicators such as impermeability, frost resistance, carbonization resistance, and corrosion resistance are all excellent, which can increase the service life of concrete structures. At the same time, the weight is reduced, which can reduce the risks of transportation and installation.
