Abstract
The invention relates to a drainage method for building construction in mountainous regions with large precipitation, which is characterized in that when flat construction is carried out in a field, a water intercepting ditch and a certain amount of precipitation wells in a ring field are built along the position of 50-100cm of a fence, then drainage ditches and a certain amount of precipitation wells along a main trunk are built on one side of the main trunk by utilizing a construction main trunk in the construction region, one drainage ditch is arranged at intervals of 30-50 meters, temporary steel plates are covered on the upper parts of the drainage ditches needing to enter and exit by large machinery and are used for vehicles and machinery to enter and exit the construction field, and the ordered construction and the smooth drainage in the field are ensured; finally, when a plurality of steps are constructed, the building plane on the same construction step looks for slopes towards the drainage facilities on two sides as much as possible, and the drainage facilities generally adopt a method of descending and connecting layer by layer from the upper layer to the lower layer. The invention reduces the influence of rainwater siltation on site construction, reduces the work waste of site workers and saves the construction period cost.
Description
Technical Field
The invention relates to the field of house construction, in particular to a drainage method for building construction in mountainous regions with large precipitation.
Background
With the rapid development of construction enterprises, the construction market of coastal areas is transferred to western areas, various construction technologies of the relatively flat coastal areas are mature, but the application of the construction technologies in southwest mountain areas is less, the requirements of enterprises and markets on construction quality, progress and benefit are gradually improved, a certain method of arranging intercepting ditches and drainage ditches in construction areas is generally adopted when the construction is carried out on hilly landforms such as western rainy mountain areas, the problem that soft foundation construction machinery cannot enter the field for construction due to accumulated water and poor drainage of foundations in part of the construction areas is generally caused at present, and if the problem cannot be solved properly, the enterprises have relatively large uncertain factors in project construction period and self profit, and great risks are generated.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, provides a drainage method for building construction in mountainous regions with large precipitation, and solves the problem that the foundation of the building construction site in mountainous and waist regions with large precipitation is difficult to be constructed after being soaked by rainwater.
In order to solve the technical problem, the invention is realized as follows:
a drainage method for building construction in mountainous regions with large precipitation is characterized by comprising the following steps:
firstly, when the flat field construction is carried out in a field area, a water intercepting ditch (intercepting rainwater catchment from the outside of the field of a construction area) and a certain amount of precipitation wells (eliminating flowing water scouring stress in the water drainage process) of the ring field area are built (brick laying and low-standard concrete construction are both available) along the position of 50-100cm of enclosure protection, so that precipitation outside the construction area is prevented from flowing into the construction site and being discharged into surrounding drainage facilities uncontrollably and orderly;
secondly, drainage ditches and a certain number of dewatering wells along the main trunk road are built on one side of the construction main road in the construction area, one drainage ditch is arranged at intervals of 30-50 meters, temporary steel plates are covered on the upper parts of the drainage ditches needing to be accessed by large machinery and are used for vehicles and machinery to access the construction site, and the orderly construction and drainage in the site are ensured to be smooth;
finally, when a plurality of steps are constructed, the building plane on the same construction step looks for slopes towards the drainage facilities on two sides as much as possible, the drainage facilities generally adopt a method of reducing and connecting layer by layer from the upper layer to the lower layer, and the following points can be ensured:
1) normally working, if some parts are blocked by silt, workers need to be dispatched to clean the silted silt in time;
2) all the drainage facilities on the same floor, steps and high floors are positioned at the lowest elevation of the same floor;
3) the drainage facilities in the field are communicated and cannot be disconnected, and are arranged in a row to a three-stage sedimentation tank or a car washing tank arranged in the field.
The invention has the beneficial effects that: set up the combination precipitation system of escape canal and precipitation well at inside periphery in original construction area and construction main road next door, guarantee the certain drainage slope rate of this system, let the effectual getting rid of ponding in the place and holding back, problem that the foundation that can be great help is soaked by the water and is leaded to unable construction of machinery and very big time limit for a project that delays.
Compared with the common operation method, the method has the advantages that the field construction progress is accelerated, the influence of rainwater deposition on the field construction is reduced, the labor waste of field workers is reduced, and the construction period cost is saved.
Drawings
The invention is described in further detail below with reference to the following figures and embodiments:
fig. 1 is a schematic view of each floor of drainage facility.
Detailed Description
As shown in fig. 1: for the united villa buildings constructed in mountainous areas such as clouds, nobility, Sichuan and Yu, the height and the fall in the construction area are usually extremely large, the rainfall is abundant, and each layered platform is greatly influenced by the accumulated water when the multi-layer construction pile foundation is divided, and the drainage method for the buildings in the mountainous areas with large rainfall in the application has the following concrete method:
firstly, when the flat field construction is carried out in the field, a water intercepting ditch (intercepting rainwater catchment from the outside of the field of a construction area) and a certain amount of precipitation wells (eliminating flowing water scouring stress in the water drainage process) of the annular field are built (both brick laying and low-grade concrete construction) along the position of 50-100cm of the enclosure protection, so that precipitation outside the construction area is prevented from flowing into the construction site and is discharged into surrounding drainage facilities in an uncontrolled manner and in sequence.
Secondly, constructing drainage ditches 1 and a certain number of dewatering wells 2 (one every 30-50 meters) along the main road on one side of the main road by utilizing the construction main road in the construction area, wherein i is the water flow direction in the figure 1, and temporary steel plates are covered on the upper parts of the drainage ditches needing to be accessed by large-scale machinery for vehicles and machinery to enter and exit the construction site, so that the orderly construction and the smooth drainage in the site are ensured;
then, when a plurality of steps are constructed, the building plane on the same construction step looks for slopes towards the drainage facilities on two sides as much as possible, the drainage facilities generally adopt a method (drainage ditch, dewatering well and the like) of descending and connecting layer by layer from the upper layer to the lower layer, and the following points can be ensured:
1. normally working, if some parts are blocked by silt, workers need to be dispatched to clean the silted silt in time;
2. all the drainage facilities on the same floor, steps and high floors are positioned at the lowest elevation of the same floor;
3. the drainage facilities in the field are communicated and cannot be disconnected, and are arranged in a row to a three-stage sedimentation tank or a car washing tank arranged in the field.
