Abstract
A kind of steel-pipe pile truss protecting side slope, relate to side slope protection field, its structure is: steel-pipe pile A(1) and steel-pipe pile C(9) top and channel-section steel (4) fixing be connected, channel-section steel (4) is fixing is connected by slip casting ductule B(8), ductule B(8) vertical with channel-section steel (4) fix, channel-section steel (4) is along domatic laying, geotextiles (5) it is provided with on domatic (2), lay between channel-section steel (4) and grout rock layers (3), grout rock layers (3) geotextiles (5) to be compacted, the toe position of domatic (2) arranges concrete bed (7) and lays longitudinal drainage pipe (6).The beneficial effects of the utility model are: use truss type steel tube pilework, play the compressive property of structural member to greatest extent, avoid shearing and power of toppling that in friction pile, steel-pipe pile is produced by sliding force simultaneously, destruction to friction pile body, whole safeguard structure has construction convenience, reasonable stress science, the feature that construction costs is little.
Description
One, technical field
This utility model relates to side slope protection field, particularly to a kind of steel-pipe pile truss protecting side slope.
Two, background technology
Civil engineering it is frequently necessary to carry out slope excavating.Some are weak or loose earth is after excavation, slope stability
Very poor, easily unstability, form landslide or slope failure, need to take corresponding side slope protection technical measures.Side slope protection normal
Have by technical measures: retaining wall method, friction pile method, back-pressure backfill method, Combining Support of Frame Beams of Prestressed Anchor Rope method, slope body grouting and reinforcing method etc..Various
Method has its different suitabilitys and pluses and minuses.
Three, summary of the invention
Thering is provided a kind of steel-pipe pile truss protecting side slope for the problems referred to above this utility model, its structure is: steel-pipe pile A
(1) and steel-pipe pile C(9) top and channel-section steel (4) fixing is connected, channel-section steel (4) is fixed and is connected by slip casting ductule B(8), slip casting
Ductule B(8) vertical with channel-section steel (4) to fix, channel-section steel (4), along domatic laying, domatic (2) is provided with geotextiles (5), channel-section steel
(4) laying between and grout rock layers (3), grout rock layers (3) and geotextiles (5) be compacted, the toe position of domatic (2) arranges concrete
Drain pipe base (7) also lays longitudinal drainage pipe (6).
Construction method of the present utility model: before slope excavating, carries out vertical steel pile tube A(1 in advance along excavation line) construction,
Form the side slope protection of first order diaphram wall form.
First order side slope longitudinally excavation five to ten meters, carries out second level steel-pipe pile C(9 immediately after) construction, Yi Jiyi
The side slope protection of excavation.Channel-section steel (4) in two-stage steel-pipe pile and slope protection, forms the slope protection shape of similar truss structure
Formula, to ensure the slope stability in construction.
Points for attention: 1), longitudinally after domatic excavation 5～10m, carry out immediately stopping excavation, carry out second level steel-pipe pile C(9)
Construction.2), after this section of steel-pipe pile has been constructed, side slope protection construction is carried out immediately.3) side slope supports channel-section steel (4) and steel-pipe pile B
(8) secure attachment, to prevent channel-section steel (4) under stress, bends up upward.4) according to rock mass water content and slope stability, the
Diode stake C(9) row's steel-pipe pile can be optimized for.5) after this section of steel-pipe pile and slope protection have been constructed, Ji Kejin
The excavation of next section of side slope at the same level of row, operation repeats working procedure above, so that slope excavating at the same level and protection are fully completed.
After first order slope excavating and protection complete construction, slope excavating and the construction of prevention work of next stage can be carried out.
Ultimately form complete side slope protection system.
Technical characterstic: 1) stake is long, grade of side slope, and whether the setting of rotary churning pile to be, all can be actual according to slope soil stability
Situation is adjusted.2) side slope protection skid resistance is reached down at bottom toe, with toe by truss type steel tube stake
The drag of steel-pipe pile and the soil body balances each other.3) truss type steel tube stake side slope protection, it is to avoid the antidumping that vertical pile body uses is long
Degree so that side slope protection system stress is more scientific and reasonable, easy construction is quick, and construction costs reduces, and working security is significantly
Improve.4) this method can be used for saturated soft soil side slope, collapsible loess slope, broken upper side slope etc..
The beneficial effects of the utility model are: use truss type steel tube pilework, played structural poles to greatest extent
The compressive property of part, avoids sliding force in friction pile to the shearing of steel-pipe pile and the power destruction to pile body of toppling simultaneously, whole
Safeguard structure has construction convenience, reasonable stress science, the feature that construction costs is little；
Steel-pipe pile embeds slope soil without going through the degree of depth, produces anchorage, is greatly reduced difficulty of construction, adds
Fast project progress；
In construction, take step excavation, step by step side slope protection construction, make side slope be in all the time in digging process stable
State, it is ensured that construction equipment and the safety of personnel；
Avoid side slope unsure state when constructing again after antiskid retaining wall needs all to have excavated, multistage anti-
The shortcoming of the sliding more difficult construction of barricade.Avoiding friction pile needs the degree of depth to embed supporting course, and the shortcoming that pile body shearing strength is bigger；
This side slope protection technology wide accommodation, structure stress science, can be according to reality such as slope stability, landslide sizes
Situation flexible arrangement technical measures, are applicable to soil body high slope, fractured rock side slope, saturated soft soil side slope etc., have notable
Science, economy, convenience,
This side slope protection technology is original technology.
When have employed the protection that steel-pipe pile truss carries out weak slope body, form the mechanics rock-steady structure of reasonable science,
Avoid the unfavorable factor of the methods such as friction pile, Gravity Retaining Wall, the reinforcing of slope body, Vierendeel girder, back-pressure backfill, easy construction, make
Valency is reasonable.The method is effectively to protect during slope excavating, so working security is higher.
