Description
Technical Field
The invention relates to the technical field of pipe gallery construction, in particular to a prefabricated buttress structure for a pipeline in a pipe gallery and a construction method.
Background
With the rapid development of economy, the land use of cities is increasingly tense, so that the development of underground spaces is inevitably carried out. In the development of underground space, an urban underground comprehensive pipe gallery is also an important one. The system integrates various engineering pipelines such as electric power, communication, gas, heat supply, water supply and drainage and the like, and is an important infrastructure and a 'life line' for guaranteeing urban operation. However, in the construction of the pipe gallery, the construction of the buttress is often very complicated. At present, the conventional method for constructing the buttress needs to face the problems of difficult feeding, inconvenient construction and the like. If meet bad weather, can not in time pour the concrete after the reinforcement is accomplished, still can lead to the corrosion of reinforcing bar. Under the requirements of increasing the construction cost of projects and saving the construction period as much as possible, optimization and improvement on the pier construction in the gallery are a technical problem at present.
Disclosure of Invention
The invention aims to solve the technical problem of providing a prefabricated buttress structure for a pipeline in a pipeline and a construction method aiming at the defects in the prior art.
The technical scheme adopted by the invention for solving the technical problem is as follows:
the invention provides a prefabricated buttress structure for a pipeline in a pipeline corridor, which comprises a main structure at the top of the pipeline corridor, a buttress prefabricated block and a channel, wherein the buttress prefabricated block and the channel are arranged above the main structure; wherein:
the bottom of the buttress prefabricated block is provided with four pulleys; two channels are arranged below each buttress prefabricated block; the bottom of the channel is provided with a plurality of bottom supporting mechanisms, and the bottom supporting mechanisms of the channel are arranged at the top of the main body structure; the top of the channel comprises a long groove and two short grooves, the long groove is a rectangular groove, and the two short grooves are respectively arranged at one side and the middle part of the channel;
two liang of relative settings of four pulleys of buttress prefabricated section bottom arrange the long recess of channel respectively in, when transversely moving the buttress prefabricated section to one side of channel along long recess, remove the vertical short recess removal of following of buttress prefabricated section again, remove to the interior back of short recess, establish the billet through adding at the pulley rear and fix.
Furthermore, a main structure top steel bar is arranged in the main structure, and when the channel is pre-buried in the main structure, the bottom supporting mechanism is welded to the main structure top steel bar.
Furthermore, the top of the buttress prefabricated block is provided with a U-shaped groove, and a pipeline is installed through the U-shaped groove.
Further, two adjacent channels of the present invention are disposed parallel to each other.
Furthermore, at least 5 bottom supporting mechanisms are arranged at the bottom of each channel, one bottom supporting mechanism is arranged below each short groove, and at least 3 bottom supporting mechanisms are arranged below the long groove.
The invention provides a construction method of a prefabricated buttress structure for pipelines in a pipeline, which comprises the following steps:
the method comprises the following steps: after the embedded positions of the buttress and the channel are determined, paying off and positioning are carried out, and the channel with the size corresponding to the bottom of the buttress prefabricated block is customized;
step two: after the top steel bars of the main body structure are bound, welding a bottom supporting mechanism of the embedded channel to the top steel bars of the main body structure;
step three: after welding, pouring concrete at the bottom of the channel and the main structure together;
step four: after pouring is completed, the buttress prefabricated block is pushed into the position of the channel, the pulley on the lower portion of the buttress prefabricated block slides to one end along the long groove in the channel, and then slides to the turning position along the short groove, and then a wood block with the same size as the channel is plugged in the channel for fixing, so that the pulley is ensured not to slide any more.
The invention has the following beneficial effects: the pipe gallery internal pipeline prefabricated buttress structure and the construction method have the following advantages:
compared with a steel-wood template combined formwork, the aluminum template can be adopted during prefabrication. Which circumvents the disadvantages of steel and wood templates. For the steel form, the steel form is heavy, and the construction operation of workers is inconvenient. For the wood template, the wood template is easy to deform, has low repeated utilization rate and is not beneficial to the protection of forest resources. The invention adopts the aluminum template when erecting the formwork, thereby having the advantages of difficult deformation in operation, high construction efficiency, low manufacturing cost and better integrity.
Second, in traditional buttress formwork and concrete placement, because of the pipe gallery inner space is narrow and small, the workman is under construction inconveniently, and often can meet the problem of throwing the material difficulty. The prefabricated block used in the invention can well avoid the problems, is convenient for construction, and can reduce unnecessary material waste. In addition, the number of people for pier construction operation in the pipe gallery is reduced, the construction period is greatly shortened, and the construction cost is effectively reduced.
Three, compare in traditional buttress reinforcement form, if meet unfavorable weather factor and cause the inside ponding of pipe gallery, then can not in time carry out concrete placement after reinforcement accomplishes, the reinforcing bar can appear the condition of corrosion, and the pipe gallery inner space is originally just narrow and small, exposes for a long time like the reinforcing bar, not only is not convenient for construction operation personnel to walk in the pipe gallery, can cause the hidden danger to constructor's safety moreover. The prefabricated block can be used for well avoiding the problems, effectively eliminating the influence of external factors and ensuring the safety of workers.
And fourthly, compared with the ductile cast iron pipeline buttress, the cover pressing plate and the rib arrangement process of the ductile cast iron pipeline buttress are complicated, and the risk of rusting can be caused by using an iron metal material. The invention omits the complicated installation and splicing steps and uses precast concrete materials. Compared with the prior art, the method has the advantages of fewer construction processes, more convenience in construction and good durability.
Compared with the common precast block, the bottom of the pier precast block is provided with the pulley. When carrying out the material transportation, the input of manpower and materials that can significantly reduce reduces construction operation personnel, makes the construction more convenient. And, under the construction environment that the piping lane originally is unfavorable, simplify the material transportation flow and also can let construction operation personnel's safety more secure to a certain extent.
