The utility model additionally provides a kind of construction method of high artesian section construction Yield rainfall relation device, such as Fig. 1 to Fig. 5 institutes Show, a kind of construction method of high artesian section construction Yield rainfall relation device mainly includes the following steps that:
Step 1:In the larger position excavation and precipitation well 1 of underground bearing water, the size of dewatering well 1 is hole bottom 1.5m*1.5m, 1:1 slope is excavated, depth 1.5m;
Step 2:The 10 bottom elevation location between drawing water of rubble filter layer 9 is inserted in dewatering well 1, is built by laying bricks or stones using brick setting 10 between drawing water, while it is configured water seepage hole and filling;
Step 3:The making and installation of steel sleeve 3 are carried out, while carries out inserting for rubble filter layer 9 in dewatering well 1, is filled out To 100mm positions under the bottom absolute altitude of bed course 8;
Step 4:The installation of water plug 2 and Yield rainfall relation, water is down to position below the bottom absolute altitude of bed course 8 and carries out bed course 8 again Construction;
Step 5:Carry out the construction and sole plate reinforcing bar colligation of the waterproof layer of bed course 8 etc.;
Step 6:Water plug 2 is withdrawn from, carries out the closure of steel sleeve 3 and pouring for underplate concrete.
Further, in step 1, the arrangement spacing of dewatering well 1, size, gradient etc. are according to job site Groundwater Pressure, water are determined;
Further, in step 2 and step 3, dewatering well 1 cheat the interior embedded thickness degree of rubble filter layer 9, particle diameter, Depending on thickness ratio compactness, setting of water seepage hole etc. are according to live hydraulic pressure, soil property situation, it should be ensured that underground water can penetrate into 10 between drawing water, while it is ensured that catch pit periphery silt not with Groundwater infiltration draw water between 10.
Further, in step 4, first underground water must be down to below the bottom absolute altitude of bed course 8 before bed course 8 is constructed, with true Bed course 8 should fully be vibrated using vibrating head when protecting the concrete match ratio of bed course 8 when pouring quality, while pouring bed course 8, Seal ring 7 is it is ensured that in the medium position of bed course 8;The model of water pumper 21 and the model of steel sleeve 3 according to job site underground water hydraulic pressure, Water is determined, and ensures that drinking-water pipe 23 is smaller at least 3cm than the internal diameter of steel sleeve 3.
Further, in step 5, the specific top job execution basis of time job site actual conditions of bed course 8 and It is fixed, but must assure that underground water below the bottom absolute altitude of bed course 8 during this period;
Further, in step 6, when underplate concrete pours, should first carry out underground water drop drain into draw water between 10 Put, pouring for the concrete of steel sleeve 3 is carried out when withdrawing from time carry out water plug 2, vibration should be used during concreting Rod is fully vibrated to concrete, after the completion of in time carry out ring flange 4 closing.
Further, rubble filter layer 9 is made up of rubble not of uniform size, to accelerate to seep water and to prevent periphery silt It is lost in;The excavation size of original soil 11, gradient etc. are determined according to job site underground water hydraulic pressure, water, should after the completion of excavation The embedded of rubble filter layer 9 is carried out immediately, to prevent periphery silt loss;It is described draw water between 10 surroundings be 240 × 115 × 53 to exempt from Bake bricks and build 24 walls by laying bricks or stones, surrounding reserves a large amount of 12cm × 12cm water seepage holes when building by laying bricks or stones, and hanging hole is followed closely respectively in water seepage hole outer wall, inwall Footpath is 5mm steel wire, and inside filling river sand, a large amount of rubble filter layers 9 are filled in 10 outsides between drawing water.
In above-mentioned implementation steps, in construction, Ruo Liu sets the position of dewatering well 1 and treats whole construction of bottom plates concrete floor After the completion of closed, then staying the seam position steel plate for sealing water should be installed, the staying of steel plate for sealing water sets installation method and done with post-cast strip Method, set if need not individually stay, poured simultaneously with periphery concrete floor 12.
For bed course 8 in construction, position carries out thickening processing above dewatering well 1, and thickness should be controlled in 20cm~50cm Between, situations such as to prevent the reasons such as dewatering well 1 loosens, hydraulic pressure is larger from causing bed course 8 to ftracture, loosen, concrete strength must not Less than C15.
Seal ring 7 and ring flange 4 are welded with steel sleeve 3, is attached by welding;Adopted when blocking dewatering well 1 Poured into the micro- swollen P6 concrete of rapid hardening microlith out of steel sleeve 3, with vibrating head vibration compacting, concrete must assure that steel sleeve 3 fill;The closing for carrying out ring flange 4 is bolted after the completion of pouring, multiple waterproof is carried out to steel sleeve 3.
Seal ring 7 is connected by welding with steel sleeve 3, is installed on the medium position of bed course 8, material is steel, seal ring 7 For the width of the ring wing in 5cm~15 centimetre, thickness is not less than 1.5mm~1cm, and rubble filter layer 9 is formed for rubble not of uniform size, with Just accelerate infiltration and prevent periphery silt loss.
Original soil 11 excavates size, gradient etc. and is determined according to job site underground water hydraulic pressure, water, should after the completion of excavation The embedded of rubble is carried out immediately, to prevent periphery silt loss.
10 surroundings are 240 × 115 × 53 unburned walls of brick masonry 24 between drawing water, when building by laying bricks or stones surrounding reserve a large amount of 12cm × 12cm water seepage holes, the steel wire that hanging hole footpath is 5mm is followed closely respectively in water seepage hole outer wall, inwall, river sand is filled inside water seepage hole, draws water Between 10 outsides fill a large amount of rubbles, isolated the silt of soil layer by rubble filter layer 9, the steel wire and river sand at water seepage hole enter Row secondary filter, the effective silt filtered in a water that draws water, reduces the dewatering well surrounding soil erosion caused by precipitation, causes Water pumper blocks, situations such as hole occurs in basement bottom board.
The example only implemented above with regard to the utility model is described, but is not to be construed as limiting the scope of the invention. The utility model is not only limited to above example, and the utility model is applied to high artesian section construction Yield rainfall relation, is also suitable simultaneously In the Yield rainfall relation of general underground water, its concrete structure allows to change, and those skilled in the art can make according to the utility model Go out various changes and deformation, without departing from spirit of the present utility model, the appended claims for the utility model institute all should be belonged to The scope of definition.
Finally it should also be noted that, having made specifically to specific embodiment of the present utility model above in conjunction with accompanying drawing Bright, the explanation of above operation principle is only intended to help and understands core concept of the present utility model, it is noted that for this technology For the those of ordinary skill in field, on the premise of the utility model principle is not departed from, the utility model can also be carried out Improve and modify, these are improved and modification is also fallen within the protection domain of the utility model claims, while above-mentioned implementation Mode is only as preferred embodiment of the utility model, one skilled in the relevant art's possessed knowledge It is interior, many variations can also be made to it.
