Description

Technical Field

[0001] This invention relates to the field of water storage tank construction technology, and in particular to the structure and construction method of prefabricated assembled vertical shaft type water storage tank. Background Technology

[0002] With the rapid development of cities, rainwater and sewage treatment has become an important issue in urban water affairs. As a storage facility for collecting rainwater runoff, stormwater storage tanks can reduce runoff peaks and prevent initial rainwater runoff from polluting river water bodies. They are an important infrastructure for improving the regional water ecological environment in cities.

[0003] However, since regulating reservoirs are mostly built in urban areas and next to existing pumping stations, the available land for construction is very limited, and traditional regulating reservoirs often face the dilemma of being unable to be built due to their large land area.

[0004] Vertical shaft structures have many advantages, such as small footprint, fast construction speed, and minimal impact on the surrounding area. Using vertical shaft structures in the construction of regulating reservoirs has become a new development direction.

[0005] However, due to the characteristics of the vertical shaft structure, there is no support system inside the shaft. Using traditional methods to construct the internal structure is not only difficult and risky, but also makes it difficult to guarantee the construction quality.

[0006] In addition, the large volume of water entering the storage tank and its strong corrosiveness place higher demands on the construction quality control of the internal structure.

[0007] Therefore, how to solve the problems of high construction difficulty, high risk, and difficulty in ensuring construction quality in the internal structure of vertical shaft-type structures has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0008] In view of the above-mentioned defects of the prior art, the present invention provides a prefabricated assembled vertical shaft type water storage tank structure and construction method. The purpose is to combine modular design and adopt a fully prefabricated assembly form to achieve a fast, efficient, green and low-carbon vertical shaft type water storage tank structure, and solve the problems of high construction difficulty, high risk and difficulty in ensuring construction quality in the prior art.

[0009] To achieve the above objectives, the present invention discloses a prefabricated assembled vertical shaft type regulating reservoir structure, including a spiral-shaped drop channel set within the vertical shaft structure.

[0010] The inner side of the waterfall corridor is equipped with multiple columns;

[0011] Each of the columns is provided with multiple bracket structures on the side facing the shaft structure;

[0012] All of the aforementioned corbel structures are arranged in a spiral around the central axis of the shaft structure;

[0013] The waterfall corridor is erected on multiple of the corbel structures;

[0014] Each of the aforementioned columns comprises multiple prefabricated column segments that are spliced ​​together end to end;

[0015] Each pair of adjacent prefabricated column segments is spliced ​​together by multiple matching positioning steel bars and multiple socket holes;

[0016] Each of the prefabricated assembled column segments has at least one corbel structure on the side facing the inner wall of the shaft structure;

[0017] The waterfall corridor comprises multiple prefabricated, assembled corridor segments that are spliced ​​together end to end.

[0018] In the plurality of corbel structures arranged along the spiral, any two adjacent corbel structures along the spiral are provided with corresponding prefabricated assembly corridor sections.

[0019] Preferably, each of the prefabricated column segments has multiple positioning steel bars extending upward from the upper end face and arranged in a rectangular array on the corresponding upper end face, and multiple socket holes are provided at the lower end corresponding to the multiple positioning steel bars of another prefabricated column segment below.

[0020] Preferably, each of the prefabricated assembled corridor sections has a tenon on its underside near both ends;

[0021] Each of the bracket structures has a corresponding tenon on the top of the two prefabricated assembled corridor sections, which is provided with a corresponding corridor positioning groove.

[0022] Preferably, the side of each of the bracket structures facing the inner wall of the shaft structure is fixed to the shaft structure.

[0023] More preferably, each of the bracket structures and the inner wall of the shaft structure is provided with a pair of matching groove locking steel plates and slider locking steel plates.

[0024] Each of the aforementioned sliding lock plates is fixed to the corresponding bracket structure or the corresponding shaft structure, and the side facing the corresponding sliding lock plate is provided with a T-slot or dovetail slot extending in the vertical direction.

[0025] Each of the slider locking steel plates is fixed to the corresponding bracket structure or the corresponding shaft structure, and the side facing the corresponding sliding groove locking steel plate is provided with a slider that matches the corresponding T-slot or the corresponding dovetail groove.

[0026] More preferably, each of the bracket structures is provided with a slider locking steel plate on the side facing the inner wall of the shaft structure, and each slider locking steel plate includes two sliders extending in the vertical direction.

[0027] The inner wall of the shaft structure is provided with a sliding groove locking steel plate corresponding to the position of each bracket structure, and each sliding groove locking steel plate includes two T-slots or dovetail slots extending in the vertical direction.

[0028] More preferably, each of the T-slots or dovetail slots protrudes from the corresponding slide lock plate, and multiple stiffening ribs are provided on both sides and between the corresponding slide lock plate in a vertical direction.

[0029] Preferably, the inner cavity of the shaft structure is cylindrical, and four columns are provided inside;

[0030] The four columns are evenly distributed around the axis of the shaft structure.

[0031] Each of the prefabricated assembled corridor segments corresponds to the length of the 90-degree included angle of the corresponding spiral.

[0032] This invention also provides a construction method for a prefabricated assembled vertical shaft type regulating reservoir structure, comprising the following steps:

[0033] Step 1: Prefabricate all precast column segments and all precast corridor segments in the factory;

[0034] Step 2: Install the foundation structure for each column at the bottom of the shaft structure; during installation, set the height of each foundation structure according to the rise of the spiral line to form a spiral rising structure;

[0035] Step 3: Sequentially hoist the upper layer of the prefabricated column segment of each column, so that each two adjacent prefabricated column segments are spliced ​​together by multiple matching positioning steel bars and multiple socket holes. During the descent of each prefabricated column segment, the corresponding sliding groove locking steel plate and sliding block locking steel plate are aligned and inserted.

[0036] Step 4: Grouting is performed between the multiple positioning steel bars and multiple socket holes of each pair of prefabricated column segments that have been spliced. The groove locking steel plate and the slider locking steel plate are welded and fixed.

[0037] Step 5: After completion, hoist the corresponding prefabricated assembled corridor section, and position each prefabricated assembled corridor section and the corresponding two corbel structures through matching tenons and corridor positioning grooves, and then reinforce them with grouting.

[0038] Step 6: Repeat steps 2 to 5 until the assembly of all prefabricated column segments and all prefabricated corridor segments is completed.

[0039] The beneficial effects of this invention are:

[0040] The internal structure of the prefabricated, assembled vertical shaft-type regulating reservoir of this invention neither obstructs the flow path of fluid droplets, thus satisfying the requirement for continuous flow energy dissipation, nor erodes the structural columns, thereby reducing the corrosive effect on the concrete structure.

[0041] This invention can effectively solve the problems of high difficulty, high risk, and difficulty in ensuring construction quality when using traditional methods to construct the internal structure of ultra-deep vertical shaft-type regulating reservoirs.

[0042] This invention combines modular design and adopts a fully prefabricated assembly method, which can achieve the goals of speed, efficiency, greenness and low carbon emissions.

[0066] The prefabricated column segment 2 with corbel structure 4 of the present invention is connected by vertical positioning to meet the verticality of the column, reduce the eccentricity caused by assembly, and facilitate the vertical load transfer of the structure to the bottom of the shaft structure 1.

[0067] like Figure 7 and Figure 8As shown, in some embodiments, each prefabricated column segment 2 has multiple positioning steel bars 3 extending upward from the upper end face and arranged in a rectangular array on the corresponding upper end face, and multiple socket holes are provided at the lower end corresponding to the multiple positioning steel bars 3 of another prefabricated column segment 2 below.

[0081] like Figure 2 As shown, the present invention also provides a construction method for a prefabricated assembled vertical shaft type regulating reservoir structure, including the following steps:

[0082] Step 1: Prefabricate all prefabricated column segments 2 and all prefabricated corridor segments 6 in the factory;

[0083] Step 2: Install the foundation structure of each column at the bottom of the shaft structure 1; during installation, set the height of each foundation structure according to the rise of the spiral line to form a spiral rising structure;

[0084] Step 3: hoist the upper layer of prefabricated column segment 2 of each column in sequence, so that each two adjacent prefabricated column segments 2 are spliced ​​by multiple matching positioning steel bars 3 and multiple socket holes. During the descent of each prefabricated column segment 2, the corresponding sliding groove locking steel plate 42 and sliding block locking steel plate 41 are aligned and inserted.

[0085] Step 4: Grouting reinforcement is carried out between the multiple positioning steel bars 3 and multiple socket holes of each pair of prefabricated assembled column segments 2 that have been spliced. The sliding groove locking steel plate 42 and the sliding block locking steel plate 41 are welded and fixed.

[0086] Step 5: After completion, hoist the corresponding prefabricated assembled corridor section 6, and position each prefabricated assembled corridor section 6 and the corresponding two corbel structures 4 through matching tenons 61 and corridor positioning grooves 5, and then reinforce them with grouting.
