Abstract
The invention is a high light type anchor rope sheet-pile wall and a construction method, and is characterized in that the anchor rope sheet-pile wall is composed of a pile, a breast board, a prestressed anchor rope and earth fill, the anchor rope is connected with the pile via a connecting piece, and the breast board is arranged between the earth fill and the pile. The construction sequence is as follows: measurement positioning; pile pit digging and check of foundation subsoil; meanwhile breast board prefabrication; pile body reinforcing steel bar manufacture and installation; pile body concreting; meanwhile anchor rope pore-forming, anchor rope manufacture, anchor rope holing, inner anchor section grouting anchoring and preservative treatment; breast board installation; earth filling; channeling for embedding the anchor rope in the fill; preservative protection of anchor rope; anchor rope pre-tensioning; breast board installation; each anchor rope of grading tensioning; anchor sealing. Not only does the invention have novel structure, but also the structure further has the advantages of good earthquake resistance, less space occupation, short construction period, much waste bank consumption, etc. The invention is applied to retaining and constructing roadbed in the conditions of steep terrain and geology in mountain areas, in particular having obvious advantage in the aspect of construction cost and much strong practicability.
Description
Technical field
The present invention relates to highway, railway, mine, foundation ditch, municipal engineering construction technical field, specifically a kind of high light anchorage cable pile panel wall and job practices thereof that is applicable in highway, railway, mine, foundation ditch, the high embankment retaining engineering of municipal engineering.
Background technology
In present highway, railway, mine, foundation ditch, municipal engineering construction, the anchored pile board wall mainly is used in the middle of the cut slope engineering, the construction of anchored pile board wall generally is first construction stake, reserve anchor cable hole and reinforcing bar during construction stake in the stake, excavation stake back, a limit soil body then, limit link plate, the prestress anchorage cable and carry out stretch-draw of constructing again during to the anchor cable position, repeat excavation-link plate-anchor cable construction operation successively, until road bed.The high light anchorage cable pile panel wall of embankment since the free section part of anchor cable in banketing, anchor cable has certain inclination angle, require to banket in the roadbed standard to want the placement in layers compaction in layers, roadbed bankets and anchor cable construction produces contradiction, for solve banket and anchor cable construction between contradiction, the present invention has studied the job practices of high light anchorage cable pile panel wall.
Summary of the invention
The objective of the invention is to solve in the construction of high light anchorage cable pile panel wall and banket and the anchor cable construction technical barrier, a kind of short construction period, practical high light anchorage cable pile panel wall and job practices thereof are provided.
Technical scheme of the present invention is: high light anchorage cable pile panel wall can be divided into two kinds of separate type anchored pile board wall and Cast-in-situs type anchored pile board walls according to stake plate pouring type difference, and separate type anchored pile board wall is construction separately, and cast-in-site, plate site prefabrication are adopted in stake; And the cast of Cast-in-situs type anchored pile board wall stake slab integral.High light anchorage cable pile panel wall structure is: by stake, breast boards and (prestressing force) anchor cable and banket and form, anchor cable is connected by connector with stake, banket and stake between be grade native plates.
The job practices of high light anchorage cable pile panel wall is as follows:
Sequence of construction: measurement and positioning → stake hole excavation and check of foundation subsoil (prefabricated breast boards simultaneously) → pile body reinforcement fabrication installation → pile concrete builds → (carrying out anchor cable pore-forming → anchor cable making → anchor cable hand-hole → interior anchor section slip casting anchoring and preservative treatment simultaneously) → breast boards installs → banket → in embankment grooving imbed anchor cable → pre-stretch-draw → breast boards of anchor cable anti-corrosion protection → anchor cable and install → banket → initial tensioning → circulation carries out embankment and rolls; anchor cable is anticorrosion; each layer of breast boards installation → grading tension anchor cable → sealing off and covering anchorage.That is:
1) measurement and positioning: press plan and measure unwrapping wire, the stake position is fixed;
2) stake hole excavation: the stake sectional dimension is 0.6m * 0.8m, adopts the way excavation stake hole of manually digging hole, stake hole supporting while excavating;
3) reinforcing cage system is installed: press design drawing establishment reinforcing cage;
4) template system peace:, and install firm along pile body by the sectional dimension custom made forms of stake;
5) concrete pouring: the disposable continuous pouring of separate type anchored pile board wall pile concrete, breast boards is prefabricated, the disposable continuous pouring of Cast-in-situs type anchored pile board wall stake slab integral;
6) anchorage cable anchoring section construction: 1. anchor cable boring, 2. anchor cable selection and making, the 3. preservative treatment of anchorage cable anchoring section;
7) breast boards lifting: separate type anchored pile board wall adopts the way of lifting that breast boards is installed;
8) banket: delamination fills layered rolling;
9) the free section construction of anchor cable: when banketing to the anchor cable position, anchor cable hole and anchorage cable anchoring section line from the stake, grooving is carried out the free section construction of anchor cable, and is carried out the free section preservative treatment of anchor cable, to the pre-stretch-draw of anchor cable so that anchor cable is straight;
10) banket: fill the groove that digs because of the free section construction of anchor cable, anchorage cable stretching to anchor cable is designed pulling force;
11) repeat 7)-10) step, up to the roadbed design absolute altitude;
12) sealing off and covering anchorage: super 1.15 times of being stretched to the design pulling force of all anchor cables, anchor head adopts the preservative treatment of concrete sealing off and covering anchorage then.
The good effect that the present invention has compared with prior art is as follows:
High light-duty retaining structure is novel structure, advanced technology, saving investment not only, simultaneously this structure also have shock resistance good, take ground less, advantage such as the useless Fang Duo of short construction period, consumption, relatively adapt under the steep landform of mountain area horizontal wall inscription, the geological condition roadbed is propped up retaining construction, especially aspect construction costs, have significant advantage.
High light anchorage cable pile panel wall job practices has solved the construction key issue that exists in the high embankment retaining structure in the mountainous area highway, high light-duty anchored pile board construction method practicality is stronger, to provide construction to instruct under conditions of similarity, building high light retaining structure, anchorage cable anchoring section and the separately construction of free section, elder generation's construction anchorage cable anchoring section, when banketing certain altitude, the free section construction of anchor cable is carried out in grooving in banketing.This job practices and the certain altitude that ought banket are holed outside stake again, and the construction anchor cable is compared, and can shorten the construction period, reduce engineering quantity, and more important is to guarantee anchor cable and the construction quality of banketing, and has guaranteed the quality of whole engineering.
Along with further going deep into of Mountainous Highway Construction, high light-duty retaining structure technology will obtain wide popularization and application, further creates favorable social and economic benefits.The development level that has advanced China to prop up the retaining technology jumps onto a new step.
