Abstract
The utility model provides integral type gutter structure, crown beam is performed at the top of fender post, the back side of crown beam closely gutter, wherein, the rear wall of crown beam also serves as the antetheca in gutter, the rear wall of crown beam is equipped with notch, and the reinforcing bar one in crown beam is passed through the reinforcing bar two arranged in notch and gutter and linked together using lap-welded mode, and the crown beam and gutter after connection are connected as one by casting concrete.It combines to form overall structure with the crown beam for going along with sb. to guard him stake top in the gutter, its globality is stronger, the good supporting role of fender post avoids gutter and occurs the adverse consequences such as differential settlement, cracking in use, it is in gutter under safe and reliable state, it effectively avoids reducing the risk that the soil body around gutter is disturbed by rainwater in the rainwater intrusion supporting construction behind soil body.
Description
Technical field
The utility model relates to integral type gutter structures, belong to foundation pit Yield rainfall relation technical field.
Background technique
Along with the fast development in city, deep-foundation pit engineering presents the growth of blowout, not only builds class in traditional room
It is related to deep-foundation pit engineering in engineering, and there is also a large amount of in newly-built urban track traffic (subway) and pipe gallery project
Deep-foundation pit engineering.
Unavoidable problem when water is deep foundation pit construction, it may be the principal element for inducing deep basal pit safety accident,
Scientific and reasonable Yield rainfall relation facility can effectively reduce influence of the water to deep foundation pit construction.
Traditional Yield rainfall relation facility is mainly reflected in: (1) dewatering well, which is arranged, reduces underground water within the scope of foundation pit；(2) on slope
Gutter, sump is rationally arranged in top, slope foot position, in time excludes water.The above-mentioned treatment measures for water, which can satisfy, to be wanted
Ask, but still remain shortcoming: (1) barrier properties in gutter are poor, and especially in the position of structure sediment seam, water can usually seep
Enter in the soil body through gutter, soil bearing capacity is caused to reduce；(2) integral strength in gutter is low, and seepage through soil mass destroys
Afterwards, cause gutter to be cracked, cause the water of the overwhelming majority to enter in the soil body, influence the safety of foundation pit.
Utility model content
To solve the above-mentioned problems, the utility model provides integral type gutter structure, it is therefore an objective to guarantee the steady of gutter
It is qualitative, reduce the interference of water base hole surrounding soil, it is ensured that the construction safety of foundation pit.
In order to achieve the above technical purposes, the utility model adopts the following technical solution: integral type gutter structure is being enclosed
Perform crown beam at the top of fender pile, the back side of crown beam closely gutter, wherein the rear wall of crown beam also serves as the antetheca in gutter, crown beam
Rear wall be equipped with notch, the reinforcing bar one in crown beam passes through the reinforcing bar two arranged in notch and gutter and uses lap-welded mode
It links together, the crown beam and gutter after connection are connected as one by casting concrete.
Preferably, impervious barrier is formed after the waterproof mortar cover operation of the surface in gutter, it is ensured that water will not be through draining
In the soil body that ditch penetrates into.
Preferably, it is equipped with water blocking platform at the top of crown beam, guard rail is installed on water blocking platform, rainwater can carried out effective
Stop.
Preferably, the section in gutter is in zigzag shape.
Preferably, it is installed with subsiding crack on gutter, local antiseepage drain process is carried out in the position of subsiding crack, it is ensured that no
Because malformation causes to damage.
The utility model is to connect gutter to form overall structure with crown beam, while the rear wall of crown beam also serves as gutter
Antetheca can guarantee the overall stability in gutter, stay the position for setting subsiding crack to carry out Anti-seeping technology in gutter, it is ensured that will not
Because malformation causes to destroy；At the same time, when gutter is constructed, with waterproof mortar on its surface before concrete final set
Impervious barrier is formed after cover operation, guarantees that gutter has enough impermeabilities.
The technical effect of the utility model:
1, the utility model can ensure the overall stability in gutter, will not destroy, give full play to because the soil body settles
Its work effectiveness；
2, the utility model structure is simple, convenient and quick construction, and the impervious barrier on surface can effectively prevent water through row
Ditch and penetrate into the soil body, reduce influence of the water to deep pit monitor.

Specific embodiment
With reference to the accompanying drawing, the utility model is described further.
Integral type gutter structure as shown in Figure 2 performs crown beam 3 at the top of fender post 1, and the back side of crown beam 3 is closely
The undisturbed soil in gutter 10,10 slot bottom of gutter will have enough bearing capacities, wherein the rear wall of crown beam 3 also serves as gutter 10
Antetheca, the rear wall of crown beam 3 are equipped with notch 9, carry out water blocking platform 6 and guard rail 7, the reinforcing bar one in crown beam 3 simultaneously in crown beam 3
4 pass through the reinforcing bar 25 arranged in notch 9 and gutter 10 is linked together using lap-welded mode, 3 He of crown beam after connection
Gutter 10 is connected as one by casting concrete, when carrying out concrete pouring operation, adequately to be vibrated, to guarantee
The compactness of concrete.
Before concrete final set, with waterproof mortar to formation impervious barrier 8 after the surface finishing operation of gutter, it is ensured that water will not
Through hardening concrete and penetrate into the soil body, cause soil bearing capacity to reduce.
The gutter 10 should be stayed according to the requirement of design and set subsiding crack, local antiseepage is carried out in the position of subsiding crack
Drain process, it is ensured that not because malformation causes to destroy.
Gutter structure provided by the utility model has the characteristics that good integrity, impermeability are strong.It is mainly manifested in draining
The reinforcing bar of the arrangement of ditch bottom of trench is reserved the reinforcing bar in notch with crown beam and is linked together using lap-welded mode, casting concrete
After make both connection formed overall construction or gutter bottom of trench arrangement reinforcing bar and crown beam reserve both reinforcing bar in notch
The side wall of integrated construction, crown beam also serves as the side wall in gutter；It is made on its surface of waterproof mortar before the concrete final set of gutter
Overlay treatment forms it into impervious barrier, it is ensured that in the soil body that water will not be penetrated into through gutter.
The utility model construction technology is as shown in figure 3, specific as follows:
(1) after foundation pit enclosure stake 1 is constructed, chiseling pile head operation is carried out to fender post 1；According to 3 ruler of crown beam of design
