The present invention has compared with prior art proposed the complete heavy caliber brick that is used for of a cover and has mixed reversal of the natural order of things well construction technology, can guarantee construction quality, for examination provides a new standard.
The specific embodiment
A kind of heavy caliber brick mixes reversal of the natural order of things well construction technology,
The position of a, selection working pit
Take into full account following factor:
1. being convenient to the pipeline butt joint scope of operation and well chamber builds;
2. be convenient to an excavation of foundation pit and a cubic metre of earth transportation;
3. on the ground and underground structure, all kinds of pipe network are easy to take to protect and the measure of safe construction;
4. have a good transport service;
B, working pit excavation
1. cut the earth symmetrically the bottom on every side along the borehole wall according to position line, each digging depth must not surpass 500 mm, digs the mid portion earthwork after the border puzzles, and symmetry is constructed downwards in this order.Masonry according to collar tie beam top absolute altitude control top is built by laying bricks or stones, descends the joint excavation after top well bore intensity reaches 70%.Require symmetry to draw to dig a well the soil layer of wall below, draw at every turn and dig width≤600 mm, the degree of depth≤500 mm, till designing invert elevation (IE) below 500 mm.According to soil property situation and cutting depth, need per 3 m reinforced concrete circle beam to be set together.
2. the borehole wall adopts MU7.5 mortar MIO brick to build by laying bricks or stones rapidly and draws the well bore that digs part, and wall is wide to be that 240 mm bricks mix supportings in-1~-5 m scope downwards from the face of land ,-6~-be to insert φ 6200 mm steel lacing wire supportings during 370 mm bricks mix in the 9m scope.
3. collar tie beam adopts the reinforced concrete structure of 400 mm X400 mm, and main muscle adopts 014 mm, and stirrup adopts φ 8200 mm, and topping is 30 mm, and concrete strength is C20.
4. base plate is thick is 200 mm, and concrete is C25, and the sump of 1 500 mm X 600 mm is set simultaneously.
5. back backrest: for upper pipe working well, the reversal of the natural order of things well is provided with backrest behind the concrete according to pipeline rout to the set absolute altitude.In order to guarantee push pipe working space and backrest area, need will backrest place, back the well bore body of wall remove, and downwards (below, shaft bottom), outwards (well bore is outside) draw and dig, draw to dig and be of a size of 3.0 m X2.5 m, thick is 1.0 m, uses C25 concreting.
6. be unearthed and draining: adopt manual work to fetch earth; (hoist cable must be with the tough and tensile rope made of hemp or the nylon rope of diameter >=16 mm with a capstan winch and large bamboo or wicker basket; Knot firmly, safety arrestment and hook gear arranged) from the hole, hang soil, or adopt hoist engine to cooperate the tripod vertical transport.Sump central drainage is adopted in draining, with the bright row of submersible sewage pump, can use light well point precipitation when the water yield is big.
Points for attention
1. Brick for building should be carried and use water saturates the previous day.
2. select medium coarse sand for use, back mud content≤3% sieves.
3. must strict symmetry excavate, symmetry is built well bore by laying bricks or stones.
4. must be with digging with block, forbid to draw and dig that the back is overnight builds again.
5. draw and dig end and need treat to construct once more after masonry reaches 70% intensity for every layer, in mortar, mix early strength admixture in case of necessity.
6. the masonry palpus fissure of displacement forbids to occur vertical straight joint, and mortar must be full.
7. along well bore vertical per 2113 lath of 20 mm X, 10 mm together is set, with the variation of observation well bore.
8. in well depth reaches during the fine sand soil layer, should per 300 mm add the hoop reinforcing rib of 2 φ 10 mm.
C, drainage of foundation pit
Drainage of foundation pit is extremely important, should establish necessary drainage.Design ponding well, gutter forbid ponding to soak foundation ditch in the foundation ditch.Forbid to drench with rain, soak in the 3.0 meters scopes in outside, hole, should effectively dredge when rainy.The foundation ditch team leader is responsible for the draining of construction period.The security official is responsible for supervision, the underproof rectification of hidden danger down notice.
The job site is arranged
1, the construction layout is provided amenities for the people in line with favourable production, meets the principle of civilized construction requirement:
2, according to the construction characteristic and the requirement of engineering, simplify construction installation as far as possible, satisfy the construction needs;
3, the place is arranged and should be convenient to construction, does not influence a works area existing utility and an interior transportation again;
According to the prospecting to the job site, the needs of practice of construction have carried out preliminary layout to temporory structuries such as construction barracks, temporary roads, also need when specifically arranging to do concrete adjustment according to field condition.
D, active well are made
Can consider to take brick oval reversal of the natural order of things well reverse construction according to soil property situation and pipe network distribution; Active well borehole wall brickwork thickness is taked 240mm; Need below the 4m every 1m reinforced concrete circle beam is set together, be provided with more than the 4m 4 road constructional columns-6~-builds by laying bricks or stones for the 370mm brick is mixed in the 9m scope.
