S4: referring to fig. 11, equally divide each layer piping lane side wall into the N section, the construction of piping lane side wall multilayer flowing water, and in the adjacent two-layer piping lane side wall, lower floor's piping lane side wall is in advance in the construction of upper pipe lane side wall.
Specifically, at first, construct first layer piping lane side wall 14, lower floor's side wall promptly, before constructing first layer piping lane side wall 14, should demolish second pipeline concrete support 9 earlier, avoid causing the influence to piping lane side wall construction.
Further, when constructing first layer pipe rack side wall 14, can divide into the N section with first layer pipe rack side wall 14 along pipe rack length direction and construct. Pour first section pipe gallery side wall earlier, first section pipe gallery side wall concrete curing accomplishes the back, and construction equipment moves back the mould and slides along the track 18 that slides and carry out second section pipe gallery side wall construction to this step of repetition is under construction first layer pipe gallery side wall 14.
In this embodiment, when constructing arbitrary section of second section pipe rack side wall to N section pipe rack side wall of first layer pipe rack side wall 14, can begin flowing water construction second layer pipe rack side wall 15 at any time, also divide into the N section during the construction of second layer pipe rack side wall 15, and every section all is the same with first layer pipe rack side wall 14's length, constructs second layer pipe rack side wall 15 according to the segmentation in proper order.
S5: referring to fig. 5 and 6, when the pipe gallery side walls are constructed to the level of the horizontal partition 16, for the sake of understanding, in the present embodiment, after the first layer of pipe gallery side walls 14 is constructed, that is, the level of the horizontal partition 16 is reached, the horizontal partition 16 and the intermediate wall 17 are constructed.
In this embodiment, the horizontal partition 16 and the intermediate wall 17 are both prefabricated structures, which can significantly improve the construction efficiency, and the intermediate wall 17 at this position is a lower prefabricated intermediate wall 17; and in order to avoid the intermediate wall 17 from affecting the construction of the side walls of the upper pipe gallery, the height of the intermediate wall 17 should be flush with the height of the constructed pipe gallery partition wall. Then, paving a sliding rail 18, erecting construction equipment on the sliding rail 18, and continuing to construct the next layer of pipe gallery side wall, wherein before constructing each layer of pipe gallery side wall, supports influencing the construction need to be dismantled;
specifically, under this operating mode, after 14 concrete of first layer pipe gallery side wall reached the strength requirement, it is different according to pipe gallery cavity layout form, mainly can divide into following 3 operating modes:
(1) referring to fig. 5 and 6, the pipe gallery structure includes horizontal partition plates 16, that is, horizontal partition plates 16 connected with the side walls of the constructed pipe gallery are arranged on both sides of the partition wall, and at this time, a foundation pit support replacing 19 (temporary support) is not required to be additionally arranged; because the strength of the horizontal partition plate 16 is relatively low, in order to ensure the safety during construction, a bracket 20 is arranged on the constructed side wall, a sliding rail 18 is erected on the bracket 20, construction equipment is erected on the sliding rail 18, and then the first concrete support 8 is removed to construct the side wall of the previous layer of pipe gallery;
(2) referring to fig. 7 and 8, the pipe rack structure includes a part of horizontal partition plates 16, that is, only one side of the partition wall is provided with the horizontal partition plate 16 connected with the constructed pipe rack side wall, and the other side is not provided with the horizontal partition plate 16 or other connecting platforms connected with the constructed pipe rack side wall, under the working condition, in order to avoid the problem that the upper pipe rack side wall lacks horizontal support in the subsequent construction, a foundation pit support replacing 19 needs to be additionally arranged at the missing part of the horizontal structure, and similarly, a bracket 20 is arranged on the side wall, a sliding rail 18 is erected on the bracket 20, construction equipment is erected on the sliding rail 18, and then a first concrete support 8 is removed to construct the upper pipe rack side wall;
(3) referring to fig. 9 and 10, the pipe gallery structure comprises horizontal partition plates 16, that is, the horizontal partition plates 16 connected with the constructed pipe gallery side wall are arranged on both sides of the partition wall, and a horizontal floor slab 23 is arranged at the elevation position of the side wall, so that the pipe gallery structure has higher strength after the horizontal floor slab 23 is constructed, at this time, a foundation pit support replacing 19 is not required to be additionally arranged, and the horizontal floor slab 23 is also constructed by adopting a prefabricated structure; because horizontal floor 23 intensity is relatively higher, so slip track 18 can directly be laid on horizontal floor 23 to demolish the first support, erect construction equipment to this slip track 18 on, then demolish first concrete support 8, with the construction of last floor pipe gallery side wall.
S6: after the construction of the side wall of the pipe gallery on the uppermost layer is finished, namely the construction of the side wall of the pipe gallery on the upper layer is finished, unloading construction equipment, lifting and constructing a top plate 24 of the pipe gallery, wherein the top plate 24 of the pipe gallery is also constructed in a prefabricated structure, and simultaneously, lifting an upper prefabricated intermediate wall 17 to the prefabricated intermediate wall 17 on the lower layer which is constructed, connecting the upper prefabricated intermediate wall 17 and the lower prefabricated intermediate wall, and finishing the connection of the upper prefabricated intermediate wall 17 and the top plate 24;
s7: and (3) installing various pipelines and foundation structures in the comprehensive pipe gallery, backfilling earthwork at the top of the pipe gallery to complete the construction of the pipe gallery, wherein the step adopts a construction method in the prior art, and the step can be implemented by the personnel in the field according to common knowledge and by combining the prior art, so the step is not repeated herein.
The implementation principle of the embodiment of the application is as follows:
the implementation principle of the construction equipment is as follows: when the construction equipment is used, the construction equipment is erected on a sliding track 18 laid in a pipe gallery structure, then the sliding structure 2 is used for driving the support 1 to move to a specified position, and at the moment, the electric telescopic rod extends to drive the template 3 to move towards the direction of the enclosure structure 7, so that the template support is realized; then, side wall pouring is started, and after the poured concrete is cured, the electric telescopic rod contracts to drive the template 3 to move towards the direction far away from the building envelope 7, so that the template is withdrawn;
compare in integral multiaspect construction forms 3, this application uses more in a flexible way, and simultaneously, also can utilize many sets of side wall construction equipment to realize the construction of multistage flowing water overlap joint, to having the multi-chamber utility tunnel construction in more branch storehouse, perhaps having the piping lane structure of irregular shape, has stronger adaptability.
The construction method has the implementation principle that: when the side wall of the gallery is constructed, a layered and segmented construction mode is adopted, so that the construction flexibility is higher, and the adaptability is stronger; meanwhile, the horizontal partition plate 16, the intermediate wall 17, the pipe gallery top plate 24 and the horizontal floor slab 23 are all of prefabricated structures, and construction efficiency can be remarkably improved.
